ᐅ Underfloor heating or not?

Hello dear forum friends (it’s quite trendy these days to “collect friends” ;-) ),

we are once again faced with a question that has led us to gather so much information and so many impressions here in the forum (and pretty much everywhere else) that we no longer really know what is best or right for us.

As mentioned elsewhere, we are going to build a bungalow. So far, the plan is to install underfloor heating (additional cost about EUR 6,000). Now we have the feeling that this might not actually be the best choice for us. I won’t repeat all the pros and cons I’ve read, but simply explain what is important to us.

What really matters is that we would like to install hardwood flooring in the living room and carpet in the children’s rooms and bedroom. If we went with underfloor heating, we are also prepared to put tiles in the living room.

Now to our concerns:

1. Tiles = cold underfoot if the underfloor heating is not running. So in the transitional seasons and summer, this could be unpleasant, especially for the lady of the house.

2. Hardwood / laminate / carpet = generally less suitable for underfloor heating. There are products that carry a “suitable” certification, but it seems clear that heating costs will increase anyway, because these floor coverings usually provide good insulation.

3. The extra cost of EUR 6,000 really surprises me. Somehow, that must be balanced out by savings in heating or improved living comfort. Apparently, installing underfloor heating does not involve a significant additional effort, at least nothing close to that price level.

4. The comfortable climate in winter is probably guaranteed while the system is running and you don’t have to worry about much. However, short-term discomfort can’t be fixed with a quick turn of the room thermostat, because the thermal inertia of underfloor heating excludes a fast response.

So we are now wondering if we are the right candidates for this system, or if it would be better to install conventional radiators and provide a return line for kitchen and bathroom.

What do you think? Are we on the wrong path? Are we missing something? Are we letting all the writing confuse us too much?

:-)

Best regards from the Ammerland

I’m no expert, but depending on the type of heating system, you probably can’t avoid using a surface heating system like underfloor heating. Because of the lower supply temperatures of, for example, an air heat pump, you won’t achieve a comfortable indoor temperature with radiators. That’s my layman’s knowledge… so take it with a grain of salt… ;-)

So the question from the forum community is likely: What type of heating system are you considering?

Hello JDoerbecker, good question that of course should be answered. We are using a conventional gas condensing boiler and will not be installing an air source heat pump.

A woman who often has cold feet gives you a subjective answer.

No, the tiles actually retain the sun’s warmth until late in the evening... I thought the heating was on, but it was the stone acting as thermal mass 😉

My parents had no basement and no underfloor heating – that’s always been a deal-breaker for me. Always cold feet, all year round, even with carpet 🙁

We already had carpet upstairs over underfloor heating in our old house – very cozy, no loss of comfort. Parquet up to 1cm (0.4 inches) thick is also fine.

...same here (knocked off my feet). Way too expensive 🙁

You don’t really feel the need to adjust it. I personally always missed having a direct heat source coming inside after being out in the cold in the old house. That’s why we got a stove, and now we also built with a stove. But the old house was poorly insulated; the current house offers a completely different, better, and cozier environment.

At 6,000, I would also reconsider. If you already have radiators that don’t bother you... I think you can still be a candidate for underfloor heating. Try to negotiate the supply temperature again or calculate what kind of loan the 6,000 would require. 😉 And if someone also writes to you about the consumption difference between radiators and underfloor heating, it might turn into a calculation that works out.

To quickly heat up:
We also have underfloor heating in our office and a party mode button. When you press it, it gets warm or warmer very quickly. So apparently, that’s possible nowadays even with underfloor heating. Otherwise, as mentioned, with a stove.
Without underfloor heating, it would never be an option for me again!

Hello, THANK YOU for the previous responses. It does seem that about 50% of new construction projects are equipped with underfloor heating. The homeowners can’t all be wrong. In the bathroom, there will be a "towel heater," and we will have a wood-burning stove anyway (already installed). The party function is interesting. I assume this works by temporarily increasing the supply temperature to achieve the desired effect; otherwise, I can’t imagine how the floor covering would warm up faster. ;-)

I have initially requested additional information about the details of the underfloor heating system and its installation. This is to ensure transparency regarding the expected costs. We will only sign a contract once ALL relevant points for us (i.e., costly ones) are clarified to our satisfaction or we reluctantly agree for other reasons despite our dissatisfaction.

I almost feel that this is a matter of belief. That’s not my strong suit compared to objective evaluation. ;-)
