hello guys,

i've read quite a bit here in the forum, but i still don't really get it...

i plan to build next year and now i'm faced with the choice of heating system.
there is no gas connection in the town where i want to build.
so if a gas heating system were an option, a gas tank would have to be buried..

which type of heating system is the most economical?
the house seller advised us against the heat pump because of rising electricity costs.. :confused:
is that really the case?
the house is supposed to be about 120 to 130m² in size..

what type of heating system can you recommend to me, i'm a bit clueless :(

thanks ;)

Hello,
Actually incomprehensible. :confused: Nearly every post, for example from me, states that there can only be a reliable answer if the actual demand (power, energy) has been determined beforehand.
Everything else is guessing or reading coffee grounds!
See above!
As a blanket statement, nonsense!

Best regards

Hello Holzwurm,

the seller probably advised you against the heat pump more because the house might end up being a bit cheaper overall
and you would be more likely to build a house with him :P

Gas and oil have no future, honestly... a heat pump probably does.

Get advice from an energy consultant, there is actually one in every district and he also COSTS NOTHING!

Best regards Eugen

so and if you now tell me how I should determine the demand I would also be grateful ;)

what kind of energy consumption is to be expected in a 125m² house?

I had actually already thought before the statement that I want to install a heat pump, only this statement confused me a bit..

@ eugen does the energy consultant also advise before building, I always thought they only come and give you tips on what can be optimized...

This might be a bit overwhelming for a layperson. That is why there are TGA planners. The consumption results from the actual energy demand in connection with the respective technical solution. With conventional heat generators, consumption is higher than demand, but the specific price per kWh is lower. With heat pumps, it is the other way around. That means very specific boundary conditions must be observed and a suitable device must be used. Otherwise, it will be an expensive adventure. An energy consultant should already be involved in the planning to find an economically sensible solution. The usual approach, where a structural engineer has to reluctantly handle the verification on the side, is rarely acceptable. Best regards

Hello,

The keyword holistic and integral planning means that nothing should be strictly excluded and not only the architect should be involved in the planning!

In addition to the client who specifies a large part of the user requirements and the architect, an energy consultant belongs to the planning team today. Due to the increasing complexity, a TGA planner may also need to be involved, but many project managers (architects) are still reluctant to do so because of the perceived "additional" costs that the client will incur. The energy consultant and/or TGA planner support the development of a long-term concept, at the beginning of which everything should be open. For example, gas should not be excluded just because there is currently no [ERDGAS] connection. A query with the local energy supplier could reveal that supply will possibly be provided in the foreseeable future as part of network development. However, a qualified energy consultant, e.g., from the trades, who accompanies the project is not free, as this is not a one-time consultation often subsidized by municipalities!

Greetings
