Total condensing storage combination boiler - complies with Part L.
With the high levels of building insulation now in place in most properties, the requirements for heating output are reducing – and this trend is set to continue with some experts predicting a drop in the boiler load due to heating from around 75% to as low as 45%. At
the same time, hot water usage is increasing year-by year as demand rises for luxury bathing facilities such as high performance showers and spa baths. If hot
water demand has risen to 55% of the boiler load, the natural next step is to gain as much efficiency in hot water mode as possible.
MCBA electronic control fitted as standard. Managing boiler and burner functions, this helps reduce the stop/start cycle significantly, ultimately saving fuel and component wear and tear.
Additional controls available, please discuss your requirements with our technical department.
Key Benefits
- Totally condensing in both hot water & heating - The best condensing combination boiler in the world
- Dual primary circuit technology
- Dual tank technology
- Modulating premix gas burner
- Weather compensation control
- Exceptional hot water outputs in excess of 80 litres per minute
- Suitable for connection to existing heating systems
- Reduced maintenance due to self-cleaning heat exchanger
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.
