ᐅ Which Heating System Is Best for a New Build?

I have a question for the experts.
We plan to build a 1.5-story timber frame house with a pitched roof. I am currently looking for the right heating system. We have decided to install a condensing boiler with a storage tank, combined with two solar collectors and a water-based fireplace stove. Underfloor heating will be installed on the ground floor. Radiators are planned for the upper floor and the children’s rooms. The bathroom will have a radiator return loop.

Does anyone have experience with this heating combination?
What would you recommend, and are there better alternatives?
Thank you very much
Robert

Hello,
I don’t understand why you want to install radiators, as this will be a high-temperature system. Are you considering floor coverings that are not suitable for underfloor heating?

It is important that the underfloor heating operates at low temperatures (<=35°C (95°F)). Your entire heating system needs to be designed as a low-temperature system. In the bathroom, I would install a towel radiator. This makes sense from an energy perspective, but it depends on the location.

That’s all for now

Hi,
Underfloor heating should naturally be cost-neutral. The materials are also cheaper, and it can be installed faster than radiators. The complex control system is also unnecessary since the supply temperature is needed for the entire house anyway.
Best regards

Hello,
Thank you very much for the previous responses. Our current apartment has underfloor heating and has not been used in the last two years, especially in the children's rooms and the bedroom. That is why my thoughts are going in this direction.

My intention is not only to heat the domestic hot water with the solar system and the water-based fireplace but also the heating water.
Best regards

Hello Robert, Underfloor heating like this is not used actively, as it heats in the background. The good thing is that you don’t need to keep adjusting it. However, when it comes to a water-based fireplace, I would seriously reconsider if I wanted one. This is a highly complex system and difficult to control. There can always be issues with it. I also believe that the expected savings amount to almost nothing. The two solar collectors you suggested are a minimum requirement and are barely sufficient to heat domestic hot water for two people. This investment will only pay off after about 30 years. I also see heating the water for the heating system as a problem. In summer, you don’t need it, and in winter the sun is not strong enough to warm the heating water. Best regards

Hi,
For me, all of this is too complicated and time-consuming. Two heating circuits with different temperatures are completely sufficient. Sufficient. A hydronic fireplace and solar system can also be included. Possibly underfloor heating as well, but that’s where it ends. The rest involves more work and never pays off. This is also where the major problems arise.
Best regards
