The ACV HeatMaster 35TC is a storage combination boiler/water heater that fully condenses during both hot water and heating mode. Offering outstanding performance for heating and hot water plus being very economical. With a full range of balanced flue option available to suit most applications.

How the HeatMaster works.

Heating: The heating return enters the lower circuit of the boiler, which allows the boiler to operate in condensing mode. The upper circuit of the HeatMaster TC is kept at a consistently high temperature due to the internal shunt pump which ensures that the primary water circulates around the heat exchanger flue tubes

Hot Water: With the upper circuit maintained at a high temperature, the HeatMaster TC is always ready to supply hot water on demand. The cold water enters through the dual coil at the base of the heat exchanger and is pre-heated before entering the hot water tank. The low temperature of the bottom circuit results in continuous condensation of the flue gases in hot water mode.

Heating and Hot Water: Once up to temperature, the HeatMaster TC is capable of producing heating and hot water simultaneously
