Hello experts,
one of many questions: What is more economical, an air source heat pump or a gas boiler? It’s just one of many points we hardly understand.
We were considering a photovoltaic system with an air source heat pump, but it seems clear that usually, the sun shines the least when you need heating the most.
Is the good old gas boiler actually more economical after all?
Thanks!

the approach sounds reasonable. What are the cost estimates for the technologies based on, and what do they include? I would always make sure that the entire system is considered, which also involves proper professional installation (e.g., hydraulic balancing).

Andreas&Marie25 May 2016 12:56Hello,
I’m new here and not sure if I’m doing everything right.
My girlfriend and I are planning to sign a contract with Bien-Zenker in the next few weeks for our house. It will be a single-family home built to the Efficiency House 2016 standard, with a living area of about 137 square meters (1,474 square feet).
We were recommended the Proxon comfort climate heating system (Proxon by Zimmermann Ventilation). However, I’m not completely sure about this concept and have some concerns about this decision.
Now my question:
Has anyone installed this type of ventilation heating system? If so, what are the consumption values (kWh) and what experiences do you have during hot summers (heat exchanger / bypass or summer box) and in low temperatures?
Thank you very much in advance.

AndreasPlü26 May 2016 23:02A different kind of question in between: Some of you are from the Stuttgart area – does anyone happen to know Pfeil Bauunternehmung Althütte? Sorry, this is unrelated to the topic, but here’s the actual question: In my opinion, (interim conclusion as of today 22:55) a sensible gas condensing boiler is definitely more economical than an air-to-water heat pump, even if you add solar thermal. However, our authorities are on a confrontational course with Russia, and there have been tensions in oil-producing countries for some time now – so we are heading toward electricity. On the other hand, Russia also supplied gas during the Cold War, and in an emergency, switching to an air-to-water heat pump is still possible, at least with underfloor heating.
How gas prices will develop – no idea. How electricity prices will develop – no clue. So both options carry risks.
Of all heat pumps, geothermal is in my opinion the best – but it’s not feasible for us or many others. There is also a certain residual risk of subsidence and groundwater changes caused by drilling, for which the owner bears the risk.

No, that doesn’t ring a bell. I would recommend talking to homeowners who have built with him. He should definitely be able to provide references.
Your comparison of gas and electricity is somewhat off. The government isn’t moving away from gas because of tensions with Russia, but because the goal is to phase out fossil fuels. Economically, gas currently can’t be beaten by an air-to-water heat pump. However, in the medium term, I’m quite sure all gas customers will face a problem caused by the government. Fossil fuel taxes are the key issue here. The energy performance certificate is another. I also weighed the options for a long time between gas and an air-to-water heat pump. As I said, purely from a financial perspective right now, gas is better, but in the medium term, it’s a self-inflicted problem. That’s why we will go with an air-to-water heat pump.
