Fuel flexibility: You decide what heats and when
With a combi boiler, you have complete control over what fuel you heat with. When you have enough wood, the boiler uses it, and if wood is not available, it automatically switches to pellets. This flexible system allows you to easily respond to the current fuel supply and optimally manage your heating costs. The boiler adapts to your situation and you don’t have to worry about a thing.

Forget about constant heating. The BLAZE HARMONY boilers have an automatic stoker that keeps the coals hot and ensures a quick relight without the need for a new preparation. Less hassle, less time spent at the boiler and more heat for you. What more could you ask for?

As soon as the wood burns out, the boiler automatically switches to pellets and continues heating without you having to do anything. This intelligent system ensures that the heat of your home never goes out, even when you’re away.
