- Suitable for heating up to 25 modern individual properties
- Designed to offer many options within one standard casing
The MASTER and MAJOR range of HIU’s (Heat Interface Units) provide central heating with optional domestic hot water in properties connected to a single boiler or a district heating system using a central boiler plant.
For many years, there has been an increasing use of centralised boiler plants in property developments. The advantages of removing gas boilers from properties and making use of high efficiency centralised boiler plants are numerous.
Advancing technologies such as combined heat and power (CHP), biomass, extract air heat pumps, waste incineration and solar are mostly uneconomical to employ in individual properties but can be utilised and combined to generate heat to numerous properties. HIU’s are fitted into each property and take the heat from the central plant; using this to provide central heating and hot water to taps.
It is easiest to think of an HIU as a boiler, running off heat from large pipes throughout the development, rather than a gas supply in each individual property. Occupants are charged for units of heat, rather than units of gas. The charge is calculated by a heat meter which measures energy use.
Higher outputs are suitable for larger properties, existing boiler replacements, connection to existing heating controls or cluster installations.
