My dad finished building the wood pellet silo. It can contain roughly 4.8 tonnes of pellets which, according to the plumber, should be enough to provide space heating and domestic hot water for a whole year.

The boiler was installed just before Christmas and hooked up to the in-floor radiant heat right away. The pellets are fed into the boiler automatically and my dad was saying that the whole system is very quiet and efficient. A hybrid hot water tank (water can be heated by the boiler as well as with solar energy and electricity) has been hooked up but is not operational yet since none of the bathrooms and kitchen are finished yet.
