Hello everyone,
We are planning a new build with approximately 190 sqm (2,045 sq ft), two stories, without a basement. The attic, about 65 sqm (700 sq ft), will be converted to include a bathroom and a storage room. The house will have a brick veneer exterior and will be built according to the energy-saving regulations. It is for a household of five people (2 adults + 3 children).
A mechanical ventilation system with heat recovery and KNX home automation are planned (if the budget allows, specifically for the KNX).
Once the house is completed, I would like to add solar thermal and photovoltaic systems after a few years.
I’m having trouble deciding between gas heating or a heat pump.
The gas connection costs me €2,500.
Could you help me make this decision?
And which manufacturer would you recommend?
Thanks!!!
Regards

Have you read the previous posts? The best heating system is the one that suits you and your building project best.difficult for a layperson

difficult for a laypersonThe alternative for better understanding is to listen to more opinions on which heating system is the best. The impact and costs of this decision are long-term and significant enough to warrant a deeper look.And in my experience, an informed layperson sometimes makes better decisions than simply following recommendations from experts.

It is a very difficult situation for us. We consulted four professionals, and three of them clearly prefer gas combined with solar.
Only one of them says that while gas plus solar is definitely safer and cheaper initially, in the long term, an air-to-water heat pump could be a better option.
Since we have to make our decision by the weekend (foundations and the slab will be built next week, and the pipes and connections need to be installed accordingly), we are worried about making the wrong choice with an air-to-water heat pump combined with photovoltaics.
Should we give in and follow the "expert opinion," or go through with the air-to-water heat pump?
I have read through the forum here but am still unsure what the best choice is, as this kind of answer is rarely straightforward.
A small additional note: we will use a wood-burning stove since we can get wood cheaply, which will greatly relieve the heating system. We only plan to heat certain rooms (bathrooms and later children’s bedrooms) with the main system, while mainly using the stove for the living room and open kitchen area.

So, do you give in and follow the 'expert opinion' or go ahead with the air-to-water heat pump? That depends on many factors.
How well is your house insulated? What energy standard does it meet?
How is the rest of the heating system designed?
Underfloor heating? How tightly installed?
What supply temperature can be used?
And so on, and so forth...

and so on... We are doing a lot of the work ourselves, and my mother’s cousin, who has built many houses, is our construction manager.
We expect to achieve approximately the KfW 55 standard, probably better rather than worse.
We will install underfloor heating in all rooms (over 210m² (2260 sq ft) of space).
Unfortunately, I don’t know the supply temperature.
We should actually receive the quotes today or tomorrow.
