Outdoor High Efficiency Condensing Boilers

With efficiencies of up to 97%, all Warmflow High Efficiency Condensing Boilers easily exceed the minimum requirements of SEDBUK Band A, and therefore operate more economically in comparison to conventional boilers. Warmflow High Efficiency Condensing 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.

Incorporating the latest Riello RDB2.2 burner and an easy-clean front servicing secondary heat exchanger, with patent pending technology, Warmflow High Efficiency Condensing Boilers have been designed specifically with the needs of the installer and service engineer in mind.

For those occasions when internal space is limited, Warmflow Outdoor High Efficiency Condensing Boilers offer a flexible and easy to install outdoor option. All Warmflow Outdoor Boilers are fully self-contained in an insulated, weatherproof casing and are supplied complete with burner, thermostat and low-level flue system, including terminal guard.
