Hello dear home builders,
I am new to this forum. It’s hard to believe, but we are also planning to build our own home and are hoping for your advice 🙂. At the moment, we are still in the idea and planning phase (please move this thread if it belongs to another topic).
We are planning a bungalow of about 190 sqm (2045 sq ft) without an upper floor or basement. The house should meet an energy-saving standard KW. Our builder uses a lightweight timber frame construction. So far, so good. Now I am looking for the right heating system. I have done some reading but haven’t gone into much detail yet, since, as mentioned, everything is still in the planning stage.
I would like to install a complete system with a bivalent or hybrid operation mode. For the main heating system, I am considering a gas or oil boiler (still checking if gas is available on the site – advice on which would be more suitable is appreciated). The heat distribution would be underfloor heating in a dry installation, ideally under ceramic tiles or laminate. As a supplementary heat source, I would like to install a water-based fireplace that feeds water to a combined buffer tank (question: what size is reasonable later for a household of four people?). Additionally, I want to integrate a solar thermal system of about 6 sqm (65 sq ft) with a south orientation to support hot water heating.
The most important question is: does anyone have experience with a similar complete system and can share information about installation costs? Also, I’m interested in the economic aspect, meaning: is the additional effort worth it financially?
Lastly, a somewhat secondary question:
If I wanted to integrate a rainwater harvesting system into the setup, would that make sense? I’m also interested in the cost-benefit considerations here.
I hope my somewhat scattered thoughts make sense and that you can give me some good advice.
Thank you in advance

the first question is how much energy you need for heating and hot water. Creating a heating load calculation would be the appropriate basis for this. Based on that, you can consider what portion can be covered by your main heating system and what additional benefit the hydronic fireplace provides. This will also lead you to the initial economic considerations.
At the same time, you might want to think about whether there is potential to improve the thermal performance of your building.
Once these basics are clarified, you can focus more on the details of the heating systems.
If gas is available, I would generally recommend a gas condensing boiler over an oil heating system.
Best regards, Erik
