Good day.
We have purchased a semi-detached house built in 1971.
130 sqm (1400 sq ft) of living space.
The attic has been converted, and the roof was insulated and re-covered in 2007.
Double glazing from 1998 with wooden frames.
The original heating system/boiler (oil) is still installed, which we would like to replace with an efficient unit meeting today’s standards.
There is no gas supply at the front door, so we can rule that out.
I personally exclude pellet heating due to the very high initial investment costs.
In the living area (living room and dining room) there is a nice Swedish wood stove heated with free wood.
What would you recommend, especially regarding an efficient and reliable oil condensing boiler?
Additionally, we are considering combining the oil condensing boiler with solar thermal systems, primarily for domestic hot water heating, where in the summer the oil consumption could be zero because the system is switched off.
I already have several offers, but I am interested in your opinions and thoughts on this!
Thank you!
Best regards

Why exclude pellets because of "high initial costs"? Our pellet boiler, including the buffer tank, installation, and all piping (there was no heating system before), cost a modest 6000 euros! Heating surfaces are not included in that price, as we are also installing underfloor heating, which costs extra.
Of these 6000 euros, we received a 50% subsidy from the BAFA.
So please, 3000 euros for a completely new pellet heating system can hardly be called expensive.

It is a Red Compact Slim boiler with 15 kW, which costs around 4000 euros. Before, the previous owner used night storage heaters. We ourselves used a wood stove. Of course, there are also boilers available for 20,000 euros. Those are probably more convenient, as with ours you have to refill the pellets manually. However, since we had the wood stove before, this doesn’t bother us, and 20,000 for a heating system simply wasn’t feasible with a total renovation budget of 60,000 euros.
Because the boiler is located in the living area (under the stairs), operating it is not a problem since you don’t have to keep going down to a boiler room. It is a rather nice, compact boiler, no less attractive than a stove, just without the visible flame.

You won’t get much advice there, as the house builders only want to sell what they offer. In any case, I would still recommend visiting a stove specialist, because in the pellet area there are also water-heating stoves, which are considerably cheaper than boilers. It’s worth taking a look just to be thorough, if the technology isn’t ruled out from the start (mainly due to the lower level of automation, meaning you have to refill them yourself). The advantage of these stoves is that they are available with lower kW output, which can be beneficial for well-insulated houses.
