My partner and I have found a semi-detached house built in 2000. We would now like to renovate it and improve its energy efficiency significantly.
The house is 140 sqm (1,507 sq ft) in size, with 5 rooms and currently an unused attic. There is no basement. A heating system (defective) and an old Wikora hot water tank are located in the attic.
We plan to install underfloor heating on the upper floor. The bathroom already has underfloor heating connected via the return line, which will remain. The living room (ground floor) is also planned to have underfloor heating installed. There is a stove there as well. The wall radiators will be removed from the rooms.
The house will receive cavity wall insulation. The attic will be insulated later with both insulated battens and partial rafter insulation. The ceiling between floors is already insulated.
Due to the size of the access hatch, we cannot place large hot water tanks in the attic – aside from structural considerations. Roller shutter boxes will also be insulated afterwards.
We are still undecided about which condensing boiler to install, which hot water tank to choose, and especially whether solar energy is sensible and feasible.
Currently, we are considering a Viessmann Vitodens W300 with Vitotronic RF300 (wireless and smartphone control) and a 120-liter (32-gallon) CUG hot water tank.
- How would you approach this?
- Does a solar storage tank make sense? We cannot fit a large tank in the attic.
The budget is very limited since we are already investing quite a lot in cavity wall insulation, attic insulation, insulating the roller shutter boxes, underfloor heating, etc.
Best regards,
Tobias
