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

If you use a unit without an outdoor installation, yes – although I wouldn’t recommend that.
Whether you need a hole in the slab depends on how and where the outdoor unit is going to be installed. Okay, so outdoor installation means having the main unit inside the utility room and an additional unit with a fan outside. In your opinion, would that be the best option?
We had planned to place the fan directly on the east exterior wall near the main system (so the heating and fan are only separated by the wall). Would the connecting pipes then be routed under the slab into the interior?
I interpreted it differently.
As a layperson, I understand that generally there are no efficiency advantages between monoblock units and split systems for the outdoor component (quite the opposite, for example, compared to an air conditioner).
The location of the outdoor unit is essentially the main factor in the decision, since a monoblock unit should be installed very close to the utility room due to the required insulation.
I therefore conclude that a monoblock system can reduce installation costs and offers a bit more space inside the utility room.
It would also be interesting to know if there are differences in ongoing costs—maintenance and repairs.

No, I only have one outdoor unit—and I would do it the same way again. The unit is installed directly on the wall of the utility room, so I don’t need to drill a hole in the concrete slab. The two water pipes and the power cable go straight through the wall.
A split system certainly has its purpose—but "I" don’t know what it is.

I deduce that with a monobloc system you reduce installation costs and have slightly more space available in the utility room.
It would also be interesting to know if there are differences in ongoing costs—maintenance and repairs. Okay, that would actually work in our favor if we want to place both units on the same wall (one inside, one outside).
Then the basic question remains whether to give the air-to-water heat pump a chance or to rely on good old gas.
