Thermal Integration Announced New Wbbsite Launch June 2021

Read on to find out what our new site will offer you.

Our History

Our story goes back to the early 1980s. George Hanson-Graville, the owner of Hydro Spartan, made advances in coil thermal tech, such as the Spartan ET50/100. In the late 80s, he founded Dedicated Pressure Systems (DPS). DPS built the Heat Bank Thermal Store, the first to replace the coil with plate heat exchangers.

In the 1990s DPS continued to design and install systems in the South East and across the UK. The first website was launched in 1998, and by 2003 DPS had built its own plant in Epsom. DPS also began to use software and electronics in new systems.

In 2011 DPS went into administration and passed their knowledge and expertise to Specflue Ltd, who relaunched as Thermal Integration. The plant was moved to Sudbury and began making new renewable tech.

Since then Thermal Integration and Heatweb have become top names in heating and hot water tech. Our brand also comes with 40 years of knowledge, expertise, training and continued research and design.
