Hello everyone,
my name is Kevin. A few days ago, I purchased an existing property. Now some renovations are planned.
Current condition:
- Oil heating system from 2004 for heating and domestic hot water
- Hot water storage tank estimated at 220 liters (58 gallons) next to the boiler
House details:
- Built in 1957
- Living area 147 square meters (1580 square feet)
Planned occupancy: up to 4 people
Planned renovations:
- Bathrooms to be refurbished with underfloor heating on the ground floor (5 square meters / 54 square feet) and upper floor (10 square meters / 108 square feet)
- Pellet stove in the living room, which will likely heat the living room and adjacent dining area (approx. 55 square meters / 592 square feet)
- Possible solar thermal system on the south-facing roof
Now to my main questions:
1. I assume I will need two different supply temperatures, right?
2. Is it feasible to use the solar thermal system to provide hot water and underfloor heating, possibly with government subsidies (e.g., BAFA funding), and to have the oil boiler as a backup heat source?
