Hello everyone,
I need your advice on the decision of which heating system we should choose for the planned renewal of the heating system.
Facts:
- Semi-detached house with two separate residential units, built in 1972, newly acquired by us in 2014
- approximately 220 sqm heated space, 186 sqm living area, 95 sqm on the ground floor, 91 sqm on the upper floor
- Building envelope insulated with 10 cm
- New windows triple glazing, winter garden (complete glazing) on the ground floor and upper floor
- Roof not insulated
- Heating distribution: (We currently plan to replace the old radiator panels with low-temperature radiators)
- Replacement of old oil heating from 1989 (low temperature), oil tank 6000 l steel tank, current consumption approx. 2500 liters per year
- No gas house connection
- Additional planned project is a photovoltaic system with approx. 8 - 9.9 KWp on the south side of the roof with a 10 KWh storage battery
- Ideally use BAFA funding 40% - 45% per system
There have been many considerations regarding the variants of the new heating system:
Option 1: Gas hybrid with solar thermal 8.5 sqm and 600l water buffer tank
(Offer with Buderus or BOSCH systems)
Option 2: Gas hybrid with 400l water tank and small additional air-water heat pump (possibly combined with photovoltaic system on the roof)
(Offer with WOLF systems)
Option 3: Air-water heat pump with integrated water treatment in the indoor unit and with outdoor unit (possibly combined with photovoltaic system on the roof)
(Offer with Vaillant systems)
Everything has its advantages and disadvantages, but I am also interested in your opinions and experiences. In particular, I am unsure about the noise level of the outdoor units of the heat pump. How loud are they really?
Or maybe you are currently planning a replacement and have a similar situation. So, please share your experiences with the systems and which you would recommend for my context.
Thank you very much for your help!!!
Best regards
Chippy

- Heating distribution: (We currently plan to replace the old radiator panels with low-temperature radiators)
[*]Basement: An old radiator panel and about 40 sqm underfloor heating (old system - probably keep heating pipes)
[*]Ground floor: Underfloor heating with 9 loops, installed in 2014, and old underfloor heating system in the winter garden as in the basement
[*]Upper floor: Six old radiator panels
