ᐅ Basement underfloor heating or low-temperature radiators

Hello

I am currently in the process of buying a house.

New build, 147 sqm (1580 sq ft) + 45 sqm (484 sq ft) basement
KfW 55 standard
Basement is heated

Basement rooms: laundry/utility room, storage room, and probably a home gym or storage room (more likely a home gym)

The standard heating in the basement is low-temperature radiators.
For an additional cost of about €2600, the entire basement can be equipped with underfloor heating.

What is better for the basement? Is the extra cost for underfloor heating worth it or not?

What are the advantages and disadvantages of both heating systems?

There isn’t a straightforward answer as to what is better or worse. If it’s going to be a playroom for small children or similar, underfloor heating is preferable. Otherwise, radiators are sufficient. HOWEVER: Radiators should be designed for low flow temperatures. Proper planning is very important here (for example, genuine low-temperature radiators intended for heat pumps with 30°C (86°F) flow temperature almost certainly won’t be installed in your case, as they are quite expensive).

The additional cost for underfloor heating is not very high. So, if it fits within your budget, I would recommend going with underfloor heating.

Underfloor heating operates at lower flow temperatures (generally resulting in lower heating costs). It provides a more comfortable warmth. The floor feels warm (at least it doesn’t feel cold, like tiles do with regular radiators). It can also increase the resale value of the house due to the higher specification.

Both systems will heat the space adequately.

A floor heating system in the basement is very valuable. Definitely install it there. The floor is the coldest in that area.

Thank you for your quick response.

I was told that low-temperature radiators are to be installed.
We do not have a heat pump but are connected to a local heating network with a combined heat and power plant (this is mandatory).

With the moderate additional cost, I would recommend (after the first winter with a low-temperature radiator in an adjacent room to the main building and underfloor heating in the basement) installing underfloor heating (heating equipment room possibly completely without an additional heat source): no noise from fans, walls remain clear, floor and lower wall area are warm.

In our case, after just four months, a fan of the (expensive) Jaga Strada Hybrid already suffered bearing damage 🙄

Ok, I also think the extra cost for underfloor heating would be worth it.

I don’t have any heating in the basement, just a transfer station where we get the hot water + a 150L (40 gallon) hot water tank.
We are connected to a local district heating network from the municipal utility company (unfortunately this was mandatory).

Has anyone here had experience with district heating?

Low-temperature radiators are not recommended? They even have extra fans installed? (So far, I’ve only had the standard old radiators.)

May I also ask how to best set up underfloor heating in the summer? Do you just leave it running?
