Hello,
we will soon be building our house with very low heating demand (close to passive house standard). Since we want tiles on the ground floor, we plan to install underfloor heating. Our architect has now suggested concrete core activation as a more cost-effective alternative. Until now, we had never heard of it.
Is there anyone heating their house this way who can share their experiences?
The heating system will be an air-to-water heat pump with controlled residential ventilation, plus a masonry heater.

Daniel-Sp9 Feb 2022 00:17With an open floor plan, you can also heat the house using just the masonry heater. However, that requires a significant amount of work.
How will domestic hot water be prepared? Is a ventilation system planned?
What does heating demand close to passive house level mean? Are you aiming to implement a passive house concept, or is the building envelope simply so well insulated that it results in a low heating demand?
Are tiles and underfloor heating planned? There are also pellet-wood combination stoves. This way, underfloor heating and hot water are covered, and you can burn wood if desired. However, you also need space for a large buffer tank and possibly for solar thermal systems for hot water production in summer. Pellets can either be filled in bags or fed automatically. Overall, this is a significant investment.
If your heating concept does not include underfloor heating, I would reconsider using tiles since, at the same surface temperature, they always feel colder than wood.
You could also combine the masonry heater with a heat pump for domestic hot water and a ventilation system. This eliminates the need for underfloor heating and allows you to design a nice masonry heater with a seating bench. Retrofitting later to a water-based heating system is not so easy, though. Depending on the size of the masonry heater and the house, you might need to load it twice daily during winter.
I’m curious to see what you will implement...
