Assurance for your heating systems, all year round


Installations need to be designed so that we control the maximum temperature that the system reaches, but we also need to have adequate management in place should this maximum be exceeded. These include the Autofill Pressurisation unit, featuring:


A


• Category 4 backflow protection: complies with water regulations for filling of “non- house systems”, negating the need for a filling loop


• Pressurisation Unit is Only 300mm Squared: meaning it is extremely compact, saving space


• No integral tank: reducing risk of legionella


• All components accessible: completely serviceable


• Volt-free high and low cut out switches: adjustable to suit requirements on site
