ᐅ Too cold to install the underfloor heating?

Hello everyone,

we are currently having a timber frame house built, and it already looks very good!
Now the ventilation, water, and electrical conduits are installed, and only the underfloor heating is missing.
It was supposed to be installed yesterday, but the site manager told me that it is too cold for that.
The house itself has been standing for 3 weeks and has been fully closed with windows, etc. since then.
So far, all trades have always worked quickly and carefully, and even the chimney builder and the plasterers on the facade had no issues with the temperatures during their masonry work.

Are the heating loops really that sensitive to temperature? The outside temperature here is at least -3°C (27°F), mostly above freezing during the day. Beforehand, it was always clearly stated that the work would be weather-independent since the roof is installed immediately.
As an amateur, I could understand that for the screed, but the pipes should be able to be laid already, right?
...but of course, I don't want to accuse anyone of anything...

Naturally, I am quite impatient right now... :-)

Best regards

Sure, but my patience is running out. As an Aries, it’s never been very big anyway :-)

We signed the contract over a year ago and were actually hoping (up until August 2017!) that we would be living there by Christmas 2017. But due to various delays (for example, the building authority/planning office!!!), the house was only erected in January. Since then, I was able to watch it “grow” almost every day, which was really great and uplifting!

The standstill now is just wearing me down.

I have been living “transitionally” for a year now (marriage, moving, job change) in my husband’s tiny flat/apartment, and my belongings are in storage.

I just want my stuff back and a proper kitchen with appliances!!!!

The worst thing is when the date gets postponed to “indefinite.” As long as I have a date to “look forward to,” it’s manageable.

Okay, enough complaining now, time to keep preparing. As soon as the scaffolding is gone, I can continue planning the garden…

Hello Tanita,

You can heat the construction site with a construction heater, which would solve the temperature issue. Of course, the cost depends on the device and the volume of the space (electricity or gas).

Well, once the underfloor heating is installed (which usually takes about 1 day), you still have to wait for better weather to be able to pour the screed.

My advice:
Forget about construction heaters and just wait. You can’t build properly in winter. Otherwise, you risk ending up with a faulty construction that will make no one happy.

Update: The screed was poured yesterday.
The project manager had set up three small electric heaters (€10 each from the hardware store, we have the same) for a while beforehand. The house was cozy, but electricity consumption has increased eightfold since the start of construction. Hopefully, the outdoor unit of the heat pump can be installed soon so we can start using the heating.
P.S.:
No, it was not warmer than two weeks ago...!
Yes, I feel frustrated...
Still, progress continues!!! :-) Starting tomorrow, we’ll begin ventilating.

Better not to ventilate at all for about a week if you care about your screed...

That is more at my feet than close to my heart...

...our project manager told us differently... ???? :-(
We will clearly question this again.
