ᐅ Comparison Between Ground Source Heat Pump and Gas Heat Pump

Steve_DHello,
we are currently gathering offers for prefabricated houses and now the exciting question arises: which heating technology would be suitable for us, ground source heat pump or gas heat pump.
Ground source:
Variable capacity ground source heat pump (geothermal heat pump) with integrated 180-liter (48-gallon) hot water storage tank and ventilation system with heat recovery (decentralized supply air, centralized exhaust air)
- Ground source heat pump Nibe F1255
- NIBE FLM (decentralized supply air, centralized exhaust air)
Gas:
Gas condensing boiler compact unit with 150-liter (40-gallon) stratified storage tank + controlled indoor ventilation with heat recovery + solar domestic hot water heating
- Vaillant auroCOMPACT VSC S 146/4-5 150 or 206/4-5 150
- 150-liter (40-gallon) stratified storage tank with integrated solar use
- Vaillant auroTHERM VFK 145V
- Vaillant recoVAIR 260 or 360 (centralized supply and exhaust air)
House:
- Danwood house type "Point 127.16"
- 1.5 storeys
- Knee wall 1.30 m (4 ft 3 in)
- 130 m² (1400 sq ft)
- KFW 55 standard
- Slab-on-grade foundation
My questions:
1. What would the approximate costs be for the two options?
2. Which option is more efficient and cost-saving over the years?
3. Is a photovoltaic system with 5 kWp worth it?
4. Can you get BAFA funding for both options?
5. How good or bad are the listed devices?
I am currently trying to get into the topic, but often it all sounds like gibberish to me. ^^
Best regards & thanks

toxicmolotof19 Apr 2016 18:353) In my opinion, the decision has nothing to do with the heating system. In summer, photovoltaic panels are of course ideal for hot water production combined with a heat pump. Whether it is cost-effective... depends on the individual case and needs to be calculated.
But please explain to me where the second mentioned device is supposed to be a heat pump. That is a gas boiler. And that probably rules out the Bafa subsidy, although I don’t know exactly what they currently fund and whether your first mentioned heat pump qualifies.

The question is certainly difficult to answer in general terms. It always depends a lot on the local situation and personal preferences. Here are some additional points to consider:
- Ground collectors / geothermal probes – what is the geographic situation like at your location?
- How many people will be living in the house?
- Estimation of hot water consumption – this is very important regarding the heat generator, especially if you plan to use a heat pump.
- If you are planning on photovoltaic panels, a high degree of self-consumption is essential to achieve a somewhat reasonable economic efficiency.
Generally, I find the combination of gas and solar energy quite sensible, especially since you won’t have a basement and, according to Vaillant, installation as a roof-mounted central unit is possible.
