Hello!
We are currently planning our single-family house (~145m² (1,560 sq ft) plus basement) and are now completely confused about the heating system! Almost everyone who wants to build a house for us says something different. It ranges from "I would never build without a heat pump and mechanical ventilation with heat recovery" to "everything other than gas is nonsense, way too inefficient!" to "What, KfW70? Why would you spend money on that?"
I understand the inefficiency at really low temperatures, but if it’s not -15°C (5°F) cold, it should work pretty well, right?
While researching, I came across hybrid heating systems that automatically use a gas boiler as backup when the heat pump’s efficiency is too low. As a layperson, that sounds like a good idea to me. What do you think? Of course, compared to a pure heat pump, I’d still have to pay for the gas connection, but as an alternative to a gas-only heating system…?
In general, I also liked the idea of a ground-source heat pump, but since we have a slight slope, some have ruled that out from the start.
Thanks in advance!

My apologies!
Best regards, Bauexperte

Do not confuse the use of the heating element with the defrosting of the evaporator!
My apologies!
Best regards, Bauexperte

It is undisputed that the fundamental assessment described by “Euro,” which in the past was only fulfilled as a formality, must now be actively carried out in order to develop a coherent overall concept. The partner in this process is the energy consultant, who independently performs a demand assessment and system design, regardless of manufacturer. In such a review, various heat pump systems as well as gas condensing boiler systems can be considered as system options.
Given the range of options available today, combined systems represent a possible alternative, such as the zeolite gas heating system mentioned by “Bolzen,” which was not discussed in detail.
Perhaps the technology behind it is not yet widely known. It is a combination of a heat pump with a gas condensing boiler system and solar thermal energy. There are some easy-to-understand videos online explaining the operation of the zeolite module used. A zeolite gas heat pump represents an energy-efficient and low-emission overall system that combines various advantages. It may be worthwhile for the planner, contractor, or energy consultant to specifically look into this technology.
Best regards, Erik
