The Thera-6 and V2000SX range

Designed to transform the performance, efficiency and reliability of home heating systems, our new range of thermostatic valves and heads offer the one-fits-all solution that stockists, specifiers and installers need.

Extended warranty

The Thera-6 head designed with quality in mind comes with 10 years . And the designed for durability V2000SX range comes with 15 years warranty. That’s pieces of mind for you and your customers.
