Hamworthy Varmax

Varmax floor standing boilers are built around an entirely stainless steel fully welded heat exchanger. This gives exceptional tolerance to a wide range of system water conditions for corrosion resistance and a long life. The range consists of 8 single boilers with outputs from 120kW to 450kW, and 4 dual models with combined outputs from 550kW to 900kW. Varmax is ideally suited for split temperature systems and projects such as medium sized district heating schemes.

High water capacity of the heat exchanger allows operation with wide differential temperatures. This removes the need for a dedicated primary circuit and enables system pumps with lower energy use to be installed. Designed for use in sealed hydraulic systems only, all boiler models are pressure tested to 6 bar and have twin return connections for improving operating efficiency with split temperature systems. Generous insulation assures standby losses are kept to a minimum.
