Air-to-air heat pump vs air-to-water heat pump vs ring trench collector - differences

Regarding models, I cannot give a recommendation Regarding additional heat sources: This results from the heat load calculation and the planned heating design.

A towel warmer is, as the name suggests, a warmer but not a radiator. For the bathroom, either plan a wall heating system or an infrared mirror. Both ensure that you have enough warmth in the bathroom.

With a properly planned underfloor heating system, you do not need additional heaters for the other rooms.

A fireplace would be only for aesthetics and rather counterproductive, as you then need a chimney and consequently a chimney sweep, as well as an additional control circuit for the controlled residential ventilation system.

Additionally, a fireplace quickly overheats the house with modern construction methods.

But you don’t know my wife very well; when she is cold, she is cold – no matter if the temperature in the room is constantly at 21 degrees. Therefore, temporary and localized supplementary heating in the living area as well as in the bathrooms is mandatory.

In the living area, we will definitely install a panoramic fireplace.

But there are heating systems or controlled residential ventilation systems where the excess heat from a fireplace is transported to the other rooms and thus used sensibly, aren’t there?

You can connect the fireplace to the underfloor heating, but even heating for 100 years would not be cost-effective. If there is space, you can transport the warm air through pipes to the upper floor... but is it worth it?

So we manage well in the bathroom without an additional heater here in the apartment. Currently, when we shower the next morning, we turn up the underfloor heating a bit the evening before so it’s a little warmer. In the morning, we turn it down again. (Only a manual wall thermostat) As soon as you shower every day instead of every other day, we would keep the bathroom permanently at 23°C, because then a “high low high low” cycle wouldn’t be worth it with such inertia. I would also assume that it doesn’t cause much additional cost if you just keep the bathroom a bit warmer, even permanently. An infrared additional heater as a large mirror would, of course, be great. Then you would have both a nice large mirror and the option to quickly raise the temperature temporarily for showering. However, I don’t find it absolutely necessary. It’s all a matter of the price you want and can invest.

None of the three variants allow for that. Air-water heat pumps and ground-water heat pumps due to the inertia of the underfloor heating, and with air heat pumps you also don’t just turn the hairdryer higher for a short time.

I haven’t followed everything completely, but if you currently live in an older house, you are not allowed to compare that. The feeling in a modern new building is completely different. If you’re still afraid of that, then you have to work with additional heaters.
Infrared is one option. But with the infrared mirror, keep in mind that some women who put on makeup in front of the bathroom mirror don’t find that particularly pleasant.

There are, but it is completely uneconomical. A lot of investment that you don’t even remotely recover.
