Unique features and benefits:

HE boilers are suitable for use on most types of fully pumped heating and hot water systems and are ideal for systems that have been designed to operate with a low return water temperature i.e. under floor heating.

An environmental investment:

Designed to be environmentally friendly, Warmflow HE boilers are highly efficient in operation and are SEDBUK ‘A’ rated. Combining economical running cost operation with comprehensive 5 year heat exchanger warranty makes Warmflow the perfect choice for oil-fired heating.

Factory-fitted with a low pressure switch as standard, the boiler is protected from damage in the event of water loss from the system. An integrated thermostatic mixing valve ensures a controlled output, as well as temperature adjustment.

The Utility Standard Boilers (UHE) are supplied with a pre-wired, factory-fitted burner and thermostat. Only one IE320 mains socket (supplied) needs to be wired on site. The multi-optional flue system can be routed through the top, back, left or right hand side of the casing.
