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
Fully pre-mix burners with 5:1 turndown
far exceed ErP NOx criteria with emissions
across the range lower than 40mg/kWh. A
built in flue gas non-return valve simplifies
flue system design whilst providing effective
protection from re-circulation of flue gases
through non-firing boilers.
Featuring comprehensive controls, Varmax boilers are capable of managing heating
systems including a domestic hot water
cylinder and up to three independent heating
circuits operating at different temperatures
to one another. Featuring in built sequence
control functionality, multiple boilers can be
managed without the need for a dedicated
sequence control panel.
Where premises are equipped with Building
Management Systems, control of the boilers
can be set to receive enable and analog
signals dictating when boilers should operate
and the magnitude of power output they
