Types of Domestic Hot Water System

There are a few different domestic hot water system types available for your home. These systems are able to work in conjunction with top water heater brands such as Hyco and Bandini. This superior sense of flexibility also allows you to choose the correct system based on very discrete metrics such as the size of the dwelling and the most appropriate type of water heater installation. Let’s take a look at some of the most common domestic systems as well as the advantages that each one has to offer.

Instantaneous Domestic Hot Water System

This type of domestic hot water system will provide you with on-demand heat thanks to the presence of electric heaters and combination boilers. As you might have already guessed, you will be provided with a continuous flow of hot water. The rate of consumption is likewise limited by your fuel supply.

Stored Heat Systems

One of the main benefits of stored heat systems is that they have the ability to offer a higher supply of hot water. This is due to the fact that the heat itself is stored for an extended amount of time. These configurations can also be used in conjunction with existing water heater installations such as solar or gas-powered options. However, you should keep in mind that any excess hot water not used will eventually go cold.

A Mains Pressure Domestic Hot Water System

If you have a smaller home, you may choose this type of domestic hot water system. This is because the presence of apparatus such as a combination boiler is not needed. Sometimes referred to as “dry loft” configurations, mains networks are known for their high levels of pressure. This is often an advantage if monobloc taps are installed or when dealing with upper floors (such as attics). If you have been concerned about tankless water heater costs, mains supplies are a good idea.

Low Pressure Stored Water Systems

In this case, a storage tank is located in the attic or on an upper floor. The tank supplies a separate hot water cylinder. Low pressure systems have the advantage of not being susceptible to fluctuations in the mains water supply. In fact, they can even function for a period of time if the mains water happens to be cut off. The only possible drawback is that their relatively low pressure may require the use of a separate pump when sending water to the upper floors of a home.

As we can see, there are a number of hot water systems to consider. This is why taking into account other aspects such as the price of a water heater installation, the available water heater brands and the associated pressure are important to look at. Of course, the team at Thermal Integration supplies only the latest configurations at highly competitive prices. Whether you want to learn more about tankless water heater costs or your home needs a total upgrade in the near future, we are always here to help.

The Best Commercial Heating Systems

What is the best way to heat a commercial building? There are a number of different types of heating systems and each system is associated with its own set of unique benefits. Still, the main intention is always the same. Commercial heating systems aim to provide a viable source of warmth in the most efficient way possible. If you hope to choose the best system for your property, it is wise to take a look at the information below.


The Different Types of Commercial Heating Systems

Heating systems come in a variety of shapes and sizes. Here are some of the most common systems used today:

  • Steam heating systems.
  • Heating systems which utilise water.
  • Natural energy commercial heating systems.
  • Heat pumps.

Steam & Water Heating Systems

Many traditional commercial heating systems use either steam or water to drive their internal processes. In either case, a boiler will first heat the steam or water. These elements are then passed on to nearby mechanisms such as a radiator via a series of pipes. One of the only drawbacks to these types of heating systems is that they are not the most efficient. It takes time to boil water to produce steam and other units may require the air to be cleansed before they begin to function; wasting a slight amount of energy.

Natural Energy Heating Systems

One of the most recent commercial heating systems to enter into the marketplace involves the use of sustainable energy. They are quite beneficial due to the fact that they are highly efficient and will therefore help to reduce your energy consumption over time. These configurations also boast an environmentally friendly edge; an obvious concern in this day and age. Still, we should mention that systems powered by renewable sources tend to be more costly to install and maintain.

Heat Pumps

Heat pumps are a final variant to mention. These commercial energy systems essentially extract warmth from the air and then recirculate throughout a given area. One main advantage with this method is that it does not require any type of additional fuel. In addition, heat pumps are also very cost-effective alternatives to more traditional methods. The only possible drawbacks are that a backup generator may be needed in the event that the air becomes too cold and that heat pumps are generally not chosen for properties associated with a colder climate.

These are some of the best choices if you have been curious to learn more about the types of commercial heating systems on the market. You will be pleased to know that Thermal Integration provides some of the most cutting-edge commercial heating systems on the market today. Furthermore, we are more than happy to explain why it is important to upgrade your property in order to embrace a modern edge.

What is a Plate Heat Exchanger?

A plate heat exchanger is a device that enables the heat emanating from one liquid to cool or heat another. A basic law of physics states that heat leaves the hottest fluid and transfers to the colder fluid. Basically, that is what a plate heat exchanger is all about.

What is a plate heat exchanger design?

The design is simple and resembles a sandwich. It comprises two, usually rectangular, plates (the slices of bread) in which the two different liquids are stored, on top of each other, separated by a thin, highly conductive wall (the sandwich filling). Plate heat exchangers come in many different sizes. Those that deploy gaskets as a means of stopping leakage can usually facilitate the addition of additional plates and may be cleaned by dismantling each plate; in welded or brazed exchangers, it is not possible to add additional plates, and the entire unit can be removed for cleaning off-site.

Plate heat exchanger calculation

If you are installing a plate heat exchanger, you need to know whether it will provide the performance you need. You may therefore need to do some calculations which are quite complex. The calculation needs to take in a number of factors, including:

  • Heat load
  • The temperatures that the heat enters and leaves the plates
  • The flow rate on both sides of the plates

If this sounds technical, don’t panic, there are applications available on the Internet that will help you with the calculation.

Types of heat exchangers

There are other types of heat exchangers in addition to plate heat exchangers. Shell and tube heat exchangers comprise a number of tubes, brigaded in bundles within a cylinder. The tubes contain hot and cold fluids which work in a similar way to how a plate heat exchanger operates. Shell and tube exchangers are favoured in the marine industry because they are easy to maintain even though they are not as efficient as plate heat exchangers.

Air exchangers, as the name suggests, use air as the cooling medium. Air exchangers have a wide application in the vehicle industry, in military vehicles, agricultural machinery and diesel and petrol engines.

Finned tube exchangers are an enhanced version of shell and tube exchangers where fins are added to each tube, significantly increasing the surface area.

It is worth remembering that of all heat exchangers, flat plate heat exchangers are regarded as the most efficient; the fact that plate heat exchange works on the basis of counter-current flow rather than co-current flow is a primary factor in this. There are different types of plate exchangers that offer different benefits depending on what you are using the exchanger for. These include vacuum brazed, dip brazed, and welded.

A final word

A detailed introduction to heat exchangers, their designs and applications would take many pages. I hope that I will have at least covered first-base for those thinking about their heat exchanger requirements and that I have answered the question, what is a plate heat exchanger?

What is Energy Heating?

When we talk about energy heating, we often think of it in terms of how cold or hot something is. But while an object such as an iceberg will feel cold to us, in truth, it will contain a lot of heat energy. Therefore, while temperature measures how cold or hot something is, heat instead measures the amount of energy within. So, how does energy heating work and how can it make heating more efficient and sustainable? Here is everything you need to know about energy heating.

What Is Kinetic Energy?

Within each object there are molecules moving around and bumping into each other. This process is referred to as kinetic energy. As the object or substance heats up, the faster the molecules move around. Eventually the heat will cause the molecules to break apart, turning solids to liquids and liquids to gas. On the opposite scale, freezing an object or substance will cause the molecules to move slower and become closer together. This is the process that turns liquid into ice, and at certain temperatures, gas into liquid. Because it is virtually impossible to reach absolute freezing temperatures, all objects retain a certain amount of kinetic energy. Therefore, as cold as an iceberg is, it can contain a lot of heating energy due to its massive size.

How Does Heat Transfer?

Another aspect of energy heating to discuss is the concept of entropy, or the second law of thermodynamics. Basically, heat will always flow from hot temperatures to cold ones. This is why ice melts on warm days, or hot coffee cools at room temperature. We can recognise this when trying to heat our homes in winter: the colder it is outside, the more heat escapes, in turn this leads to more energy usage and higher bills. To reduce this, we need to understand the three types of heat transfer: conduction, convection, and radiation. Conduction is where heat flows from a hotter solid object to a colder one. Convection is where heat circulates through a liquid or gas until the cold air or liquid is replaced. Radiation is where heat is carried directly to you through electromagnetism, such as the sun’s rays.

How Understanding Heat Energy Helps

Looking at heat energy and transfer shows us how to effectively use energy heating to heat our homes. Solids such as metals tend to have low heat capacities, meaning convection takes place, but they do not retain heat for long. Therefore, choosing a metal like copper for conducting heat works well. Water has a high level of heat capacity compared to air, which works well for convection. Finally, insulation can help prevent the escape of heat through convection or radiation. As such, this type of energy works best for industries and homes that want to be more efficient when it comes to heating and cooling.

Geothermal Heating and Cooling

Geothermal heating and cooling systems for homes have grown in popularity over the years for a number of reasons. They are a natural source of energy that is both efficient, sustainable and eco-friendly. In addition, the temperature of these sources remain constant throughout the year; this means you can use them to supply or reduce heating as needed. Also, their reliability, efficiency and low maintenance needs make them a great investment. With that said, how were geothermal heating and cooling systems discovered? Who developed them into the technology we see today? Let us take a look at some of the history behind this technology as well as their types and benefits.

The History of Geothermal Heating and Cooling

Geothermal systems have been around for thousands of years. The Qin dynasty in ancient China built hot spring spas as far back as the 3rd century BCE. A few hundred years later, the Romans popularised this energy for heating rooms and public baths. For modern geothermal systems, there are several inventors who have helped develop them into what they are today. William Thomson, the future Lord Kelvin, invented the heat pump in 1852. This would become one of the primary tools used for modern systems.

In 1912, Mexican-Swiss engineer Heinrich Zoelly used Thomson’s pump to patent an invention that would draw heat from the earth. This would become the basis for the modern geothermal system used today. During the 1940s, several inventors such as Robert Webber, J. Donald Kroeker and Carl Nielsen came up with their own unique systems that are in use today.

Types of Geothermal Systems

All geothermal heating and cooling systems use underground pipes to exchange heat as needed. The design of these exchangers determines what type of system is used:

  • Closed Loop Systems are the most common type of geothermal system. It uses water and a refrigerant such as anti freeze as a medium within the heat exchange coils. This medium remains inside the system and there is no requirement to replenish this fluid on a regular basis. These exchangers can take the form of vertical pipes drilled straight down (vertical loops), horizontally orientated within a trench (horizontal loops), or overlapping with coil-like pipes (slinky loops). In some cases the pipes can be installed beneath water sources, such as ponds (pond loops). In such cases the water source needs to be deep enough so the temperature will not be affected.
  • Open Loop Systems are a much simpler type of geothermal system. These draw heated water from an underground source which passes through the exchangers and heat pump. It discharges the used water back into the original water source away from the water intake. These systems are reliant on having access to a clean supply of water. Also, in many cases the system will need to treat the water before discharging it.

Benefits of Geothermal Heating and Cooling Systems

  • Geothermal systems are much more energy efficient than other heating and cooling systems. They can reduce energy costs in the home up to 50%.
  • There are less parts that you need to take care of. This means the system is easier to maintain and more convenient to run.
  • Regular heating and cooling systems can last between 10 and 15 years. However, geothermal systems are very durable and can last anywhere between 20 and 50 years.

Communal Heating Systems for Flats

Whether you are a landlord or a tenant there are many benefits to using communal heating systems for flats. A communal heating system is one that supplies heat to all tenants from a central heat source. This type of system can help cut down energy needs and can also reduce carbon emissions through the use of renewable energy. There are a number of products and services that can help you achieve a reliable heating system. Here are some of the available types of communal heating systems for flats, and their benefits.


Types of Communal Heating Systems

There are five main communal heating systems for flats available:

  • Type One systems are ones that provide heating only. Boilers run for 18 hours each day between 6 am and 12 midnight during the colder months of September through March. The boilers can also be optimised to increase the temperature before 6 am during any sudden cold snaps.
  • Type Two systems provide 18 hours of regular heating until midnight, at which point they shut off. These run on an “optimum start” system that allows them to begin warming up at 3 am ready to provide the ideal temperature at 6 am. Also, they will continue to provide hot water throughout the year.
  • Type Three systems are similar to Type Two except that they do not shut off at 12 midnight. Instead, these systems run at a reduced temperature overnight. These systems also have the optimum start and hot water capabilities found in Type Two systems.
  • Type Four systems do not shut off overnight and are available to run fully for 24 hours. These systems will also continue to offer hot water throughout the year as needed.
  • Type Five systems allow the tenant to have control over the level of heating and hot water in their flat. Tenants receive a heating card when they sign the agreement and can purchase heating credits from the supplier. By inserting the card into the control interface they can use as much credit for heating and hot water as needed.

For systems One through Four you can control the level of heating supplied by adjusting your thermostatic radiator valve (TRV) or room thermostat. A separate thermostat is available for hot water if no storage cylinders are supplied.

Benefits of Communal Heating Systems for Flats

There are several benefits for both landlords and tenants when it comes to communal heating systems for flats. The benefits for tenants include:

  • An efficient and reliable central heating system.
  • Instant hot water from the mains.
  • No need to maintain gas appliances or cylinders.

For landlords the benefits include:

  • The ability to monitor heating usage for each tenant from any location.
  • The ability to control the amount of central heating from anywhere.
  • Instant alerts that can be sent to mobile devices.
  • Free software for monitoring communal heating.

Communal Heating Billing – All You Need to Know!

These days one of the biggest issues that landlords have to deal with is communal heating billing. Many do not have a strategy in place to assess the rates of each tenant and send out separate invoices. However, under the Heat Network (Metering and Billing) Regulations 2014, it is the responsibility of landlords to correctly meter the heating usage of their tenants. Therefore, how can landlords best comply with this and effectively measure heating? Here is all you need to know about communal heating billing, how it works and how landlords can use it.


How Does Communal Heating Billing Work?

Landlords are required by law to monitor the heating used by each tenant and provide accurate bills accordingly. This can be daunting for individual landlords if they have no knowledge in this field. As such, they will often employ agencies who can assess heating bills on their behalf. The landlord is required to install a meter for each tenant or suitable alternative if a meter is not feasible. From there the landlord will still be responsible for setting tariffs and debt collection. The agency will handle reading the meters and sending out communal heating bills.

The Difficulties of Communal Heating Systems

Communal heating billing can create problems for both landlords and tenants. For landlords, there is the need to know how to assess heating systems as well as how best to install meters. For example, individual wiring is more reliable but costly, while daisy chaining is cheaper but can lead to mass failure. There is also the issue of incorrect readings or failing M-Bus equipment. For tenants, these heating systems can also lead to higher costs. Also, these systems prevent them from being able to choose their own energy supplier.

How HEATWEB Can Help

Here at HEATWEB we can provide expert advice and support on a range of communal heating projects. We offer a range of services including Heat Interface Units and monitoring tools that are perfect for use in communal heating.

How Combined Heat and Power Works

A system known as combined heat and power (CHP) is able to provide a much more energy-efficient means of generating electricity. The main principle recaptures thermal energy (heat) normally lost by traditional systems. This heat can then address other issues around the home or within a professional atmosphere.

In other words, this type of closed system will be able to save property owners an appreciable amount of money while still ensuring that they can enjoy a comfortable environment throughout the year. However, let’s break the notion of CHP down further in order to truly understand how it works.

Combined Heat and Power Systems Explained in Detail

The configurations associated with CHP systems:

Combined Heat and Power Explained

  • Combustion turbines
  • Reciprocating engines

Without becoming overly technical, the most important component within models is a heat recovery unit. A heat recovery unit essentially “pulls” excess heat created by the existing turbine or engine (this heat would have normally gone to waste otherwise). Heat captured transforms into a usable source of energy. This results in hot water or steam.

Steam or hot water is collected and redirected to work with other components. For example, combined heat and power systems for residential use can be used to supply energy for space heating, radiators, hot water tanks, and even cooling systems. We can therefore see that the efficiency associated with this model is extremely beneficial to the customer.

To put these systems into perspective, it has been shown that average technologies can lose up to 50% of their efficiency due to the amount of heat and energy that are wasted. On the contrary, CHP can increase this efficiency by up to 80%.

A Look at CHP Efficiency

CHP systems produce very little waste and this is important for a handful of reasons. Perhaps the most obvious is the simple fact that less waste equates to massive money-saving advantages over time. We need to remember that less energy will power a home or office environment. So, CHP can help to reduce our dependency upon fossil fuels. Finally, CHP will help to lower the carbon footprint of any property.

Are There Any Potential Disadvantages?

To be clear, it is wise to quickly mention some possible drawbacks. CHP systems are not suited for sites with no hot water or heating. Furthermore, the initial installation can be expensive (although this is normally offset by long-term cost savings). The good news is that overall combined heat and power efficiency will generally outweigh any concerns that a customer may have. However, it is wise to speak with a trained specialist. This will help you to determine whether or not CHP is the right choice for your property.

Working with the Team at HEATWEB

The team at HEATWEB boasts a wide range of experience in terms of CHP efficiency. However, we are more than happy to provide other configurations to both commercial and residential customers. This is why it is a good idea to contact one of our customer service specialists in order to schedule an appointment at your convenience.
