First of all, hi everyone
We are planning to build a new house, specifically a KfW 70 standard home from Massa Haus with 160m² (1722 sq ft) of living space.
I’m still completely undecided about which heating system to choose.
There are no gas lines available, so we would need to rent a gas tank.
The standard package includes a gas boiler with a 300L (79 gallons) storage tank and about 5m² (54 sq ft) of flat-plate solar collectors.
A controlled ventilation system with heat recovery is always included.
For now, we have decided on an air source heat pump with underfloor heating (around €13,000). Since it is a compact system, the storage tank will probably be smaller. For an additional €1,500, we could add two high-performance evacuated tube solar collectors on the roof (about €14,500 extra compared to the standard package).
If we calculate differently and stick with the gas boiler, we would also have underfloor heating with a 750L (198 gallons) storage tank (160L domestic hot water and 590L buffer) for hot water and heating support, plus about 10m² (108 sq ft) of solar collectors (approximately €16,500 extra).
One advantage I’ve read about is that the heat pump has much lower maintenance costs (inspections, chimney maintenance, etc.).
I am really unsure about what to decide.
If we go with the heat pump, should we add the solar water collectors and save money, or is it better to invest more and install photovoltaic panels on the roof? (If you can even get anything useful for around €3,500.)

... Due to the low return temperature, the condensing effect can be fully utilized only then. With underfloor heating, the serial heat emission results in a limited temperature difference of 5 to 7 K (9 to 13°F). With radiators, temperature differences of 15 to 20 K (27 to 36°F) can be achieved. Every heat generator, including condensing boilers, benefits from this. Best regards
Hello, I don’t have my own house yet, but when it comes to home heating, I think heating with wood is the best option. It is very environmentally friendly and, I believe, also less expensive. Heating oil is available as well and is just as effective and affordable. The costs and prices for gas and electricity keep rising every time and each year anyway.
Best regards, Antonia
Best regards, Antonia
