ᐅ Floor screed heating program using liquid gas / gas boiler Vitodens

Hello everyone,

our screed was completed last week, but the utility connections will likely not be installed until December. The Vitodens 200 gas heating system is already fully installed. Now to my question:

According to the user manual, the Vitodens 200 can also operate on liquefied petroleum gas (LPG). Would it be permissible for a professional to run it with a 33kg (73 lbs) gas cylinder to heat the underfloor heating?

Alternatively, we would have to use construction power to heat up, which would of course be quite expensive.

Does anyone have experience or tips for us? If we wait for the utility connections, the heating commissioning would be delayed by about 3-4 weeks.

Best regards!

Yes, that’s possible, but you will still spend 500-1000€ on it. Propane is not free.
What does the heating engineer say?

He had suggested the idea of the electric heating rod and now came up with the idea of using liquefied petroleum gas. Before I bring this up, I wanted to ask here for opinions on its feasibility and potential savings. Thanks in advance for the information – it should still be cheaper than electric heating.

Why does it need to be heated already? There should usually be a few weeks in between!
So: slow drying for the first two weeks, then construction dryers, then heating.

This is our plan – after 21 days, we want to start the underfloor heating. The utility connections would take place at least 3 weeks later, if the weather permits. The tiler is supposed to start in mid-December, which wouldn’t be possible if we only receive the utility connections in calendar week 49.

That's great. The invoice goes to the person who forgot to order the connection.
