Twin returns for maximum efficiency – Introducing Varmax

varmax-front_co_whitebgThe floor standing Varmax is a powerful, fully ErP compliant, all stainless steel condensing boiler for demanding applications with high output requirements, such as district heating schemes operating with wide differential temperature.

Twin return connections allow greater opportunity for the boiler to condense, improving system operating efficiency. Standby losses and running costs are minimised by generous insulation surrounding the heat exchanger which is made of high quality fully welded stainless steel. Less prone to corrosion caused by poor system water quality, it ensures long-term reliability.

Simplified installation is provided by an internal distribution circuit ensuring even heat distribution at low system flow rates, as well as a flue gas non-return flap making the boiler easy to install in cascade flue arrangements.

The integrated Siemens LMS controls platform delivers reliable, futureproof and simplified site controls due to its expandable controls options and built in sequence control.

The Varmax is natural gas and LPG compatible, comes with a 5-year warranty on the heat exchanger and is available in 8 single (120kW to 450kW) and 4 dual models (550kW to 900kW).
