HeatMaster® 201...

High Efficiency Range

High performance combined
boiler and water heater with fully
modulating burner technology.

The HeatMaster is a high performance hot water producer: its annular Tank-in-Tank holds a volume of hot water for peak demand. This combines the advantages of a hot water producer with integrated storage and of an instantaneous water heater, while avoiding the disadvantages of space, cost and efficiency.

All ACV stainless steel Tank-in-Tank products, it can operate at high temperature (over 90°C).

The HeatMaster has a primary circuit and can therefore also be used as a central heating boiler.

Exceptional Performance
The MCBA electronic controller regulates the boiler (start-up, safety, modulation), the shunt pump and the heating pump in response to hot water and heating demand. The MCBA offers numerous advanced features:

- A large burner modulation range - down to less than 30%
- The hot water tank is always kept at an optimum temperature
- Excellent hot water performance
- Energy efficiency is optimised in both hot water and heating modes.
