4 of 2 ReviewsThe quiet operation of my boiler allows me to enjoy the heat without distracting noise.
I’ve owned it for just a few months, and my experience with it has been excellent so far. The ECO mode, which I didn’t like in our previous boiler, was a big improvement. This function ensures that hot water is first circulated through the system, assessing whether the heat demand is met before full operation, and it has proven to be very effective
