Hello,
first of all, many thanks that this forum provides a platform for such questions.
I have the following problem that I am trying to solve and hope to get some tips from the pros.
I am interested in a house, have not bought it yet.
- Viebrockhaus, so-called 3 liter house, HAHA. Built 2000
- very good equipment in terms of bathrooms, floors, materials
- 2 upper floors total 200 sqm with mansard roof and fully developed basement with office of 90 sqm
- here it comes, hold on: they easily have 400€ electricity costs per month and blow out 10-12,000 kWh depending on the year. Electrically, mind you. For two people!
- radiators throughout the whole house. No underfloor heating!. Two fireplaces, whose draft is exactly opposite the technical room. Ok, the fireplaces also have flaps to the hallway.
- heating: 2 x exhaust air heat pumps Nibe Fighter 600 or 610 for the living area and one Nibe Fighter 315 for the basement/office.
- central exhaust system from the relevant rooms, and decentralized supply air openings in every room
Clearly, the system is so sh... that it probably heats with the heating rods 90% of the time. The ventilation must also be on, otherwise no efficiency is achieved at all.
I want to get away from these high costs. I have read up that you can tune with timers and so on, mostly ventilation off, fake temperature with thermal sensors, etc. But I think all that is not effective and annoying.
IDEA:
- since there is MASSIVE space in the technical room in the basement, including a large storage room. Use of a suitable wood pellet heating system. Chimney external draft. I don’t mind the look.
Combine the whole thing with a modern exhaust air heat pump like Nibe F135, which should only run occasionally.
To maintain the ventilation, I am afraid that otherwise it might get moldy.
The house was very dry and did not give a musty impression.
Viewing was at 35°C, scorching hot inside, of course, because they pull in the warm air.
What do you say to this, or is this nonsense? Solar thermal for hot water instead? I have also thought about leaving the old Nibe additionally in place and only using the ventilation function. What I don’t want is to break up 200 sqm of floor and install underfloor heating.
Therefore, OIL/GAS/GW/GSOL are probably out.
I have also thought about photovoltaics to cover the horrendous electricity costs, but that would be pearls before swine and in the end not even enough.
Maybe someone still has a tip.
THANK YOU VERY MUCH!
Frank
