Hello! I would like to briefly introduce myself and my project and look forward to a productive exchange! I am 42 years old and have inherited a house in a suburb. The house has been vacant for about 10 years. It was built in 1973, has about 105 sqm of living space and a small garden. I have already brought it back to the "shell condition" myself. However, my craftsmanship skills and the time available besides work for further own contribution are unfortunately limited.

The house is fully basemented; the basement is quite damp. The house has another floor with sloping ceilings. The attic is not usable/walkable because of the slopes. The house has never been renovated since it was built. It is in a corresponding condition. All windows are equipped with uninsulated roller shutter boxes. The walls are not insulated, the roof barely. The roof itself is also in need of renovation. There is an old oil heating system and no gas connection. There is also no gas connection in the street. The building core is in good condition (no damage).

I consulted an energy advisor who recommends renovation from an energy perspective to KFW House 85 standards. The package of measures includes: basement ceiling, roof and exterior wall insulation. New windows. New roof. Pellet heating with solar thermal, possibly also photovoltaics (south-facing roof 40°, about 80 sqm area). He based his calculations on an energy requirement of about 2700 euros per year. According to this, an amortization of his determined renovation costs can be expected within about 20 years. However, these costs amount to "only" 48 thousand euros.

Currently, I would receive 120 thousand euros from KFW at 0.75% + 33-36 thousand euros repayment subsidy, as well as up to 30 thousand euros subsidy from BAFA for the new heating system.

With a construction contractor, I am at about 180 thousand euros for the complete renovation in a (so far verbal) cost estimate. But this also includes bathrooms, windows, floors, etc.

How does this appear to you? Do you have any comments—possibly something I am overlooking? Especially regarding the pellet heating, I am a bit uncertain—also because the contractor has never installed one before, but was fairly confident to manage it properly. The location is ideal for me regarding family and work—in that sense, it is very important for me to be able to settle here.

Best regards!

Well, getting a completely renovated house for €180,000 stands against selling and building new. Financially, the new build already loses by a wide margin—apart from the location that suits you.

I don’t like pellets; I would rather install a "normal" air/water heat pump. Maybe even a Geisha for very little money.

But: I find €180,000 itself too expensive for 105 sqm of living space (including photovoltaics?). That’s €1,700/sqm, a good profit for the builder. If we take the estimate of the energy measures at €48,000 (insulation, windows, roof, heating), €132,000 remain for cosmetic renovations—that is floors, doors, walls, water/electrical lines. Either you get gold plates on the floors, door handles made of gemstones, OR the builder gets his new Porsche this year...

I had a thread myself on the topic of pellet heating, just search here for my name and pellet. I think it is not practical for most people.

That would be a heat pump, right? I have also considered it - but I keep reading about insufficient heating capacity or high electricity costs. Would such a pump be an alternative for a house that will be insulated in the future (but of course not like a new build)?

That is not the alternative, that is the standard. Pellets are the exotic option.
