Modulating central heating boiler
Our Combi Compact HRE A is fitted as standard with a continuously adjustable control system that automatically adjusts the boiler’s power output to the desired heating level. What’s more, it is fitted with a self-learning eco-comfort switch, which automatically turns the hot water supply heat retention feature ON and OFF. This is particularly useful if you don’t need hot water for a while, e.g. at night or when away for an extended period. Our Combi Compact HRE A is compatible with both ON/OFF and modulating thermostats using the OpenTherm protocol.
