Haeusle20163 Apr 2016 12:26Hello everyone,
We are currently facing the difficult decision of choosing between gas heating and an air-to-water heat pump.
Our cost comparison:
Gas:
Cost for gas connection approximately 3000 € (about $3,200)
Reimbursement from the construction company for the gas heating system including solar thermal -500 € (about -$530)
___________________________________________________________________
+2500 € (about $2,670)
Air-to-water heat pump:
This would currently be included in our house price.
If we decide on an air-to-water heat pump, there is still the question of whether to install a photovoltaic system.
Cost of photovoltaic system: approximately 10,000 € (about $10,700)
We would greatly appreciate any answers and advice!

Hi,
sorry if I’m a bit blunt sometimes.
This is not a cost comparison. It’s apples, oranges, and cucumbers all mixed together.
1. As I understand it, your house would be built with an air-to-water heat pump at no extra cost. The total cost of ownership is usually somewhat higher compared to gas at the moment. However, if the house is properly constructed, an air-to-water heat pump (from a good brand and correctly sized) can definitely be a viable option.
I assume the air-to-water heat pump would be installed without a solar thermal system. Whether with or without heating support, these systems don’t really add much benefit.
2. Regardless of that, you could have a gas connection installed. From my technically biased perspective, gas is far from over, and the technology is still evolving. There will be interesting developments in the future. Usually, the decision to forgo a gas connection is made when installing an air-to-water heat pump—unless you want the gas connection, for example, for a stove.
3. Photovoltaics are unrelated to all of this. They are more of a “green thumb” principle decision. With an air-to-water heat pump, you have a chance to generate a notable portion of your own energy. A little bit for heating in winter; and for about 6-8 months of the year, for hot water. Personally, I consider an air-to-water heat pump combined with solar thermal and photovoltaics to be roughly economically nonsensical.
Despite economic considerations, I’m currently having photovoltaics installed later on. The green thumb...
Solar thermal is my hobby, which was insanely expensive and ineffective, while our gas heating is very affordable and efficient.
Best regards,
Thorsten

ErikErdgas25 Apr 2016 09:11Hello Haeule2016,
thank you for your question in the forum. However, T21150 and EveundGerd are right—besides a few general placeholders, a qualified answer cannot be given based on the information you provided. Please share some initial data, and you will receive more specific answers here online.
Important information includes:
- Is this a new build or an existing property undergoing energy-efficient renovation?
- Is it a single-family house or a multi-family building? Are there possibly commercial areas involved?
- Is there already an energy standard that must be met, due to personal preferences or financing requirements (e.g. KfW, state subsidies, etc.), such as KfW 40?
- Who are the future occupants?
- Is there a defined budget for the heating system?
- Location of the property?
- And so on.
The more data available, the more reliable the advice can be!
Just looking at the gas heating part alone, if it is an existing property, the chimney renovation might be missing in the calculation. Has the gas connection been specifically requested? Maybe it is available at a reduced price when signing a supply contract? Overall, the investment for a gas heating system will be lower after a detailed assessment of the individual factors. However, there are also factors that could rule out one or another option. But here, data, figures, and facts are still missing! Please provide these so that it becomes more concrete!
