Replacing an electric heating system?

Hello all!

We are interested in buying an apartment that has an in-floor electric heating system. Where I come from (Canada), electric heating is NOT a good thing, but otherwise we are very happy with the apartment so we did some research to find out if we should continue to pursue it.

We asked to see electricity bills, which were actually quite reasonable (180 CHF / month for heating, electricity and hot water for a 150m2 apartment). However, we found out that the Swiss government is in the process of passing a law that will require all electric heating systems to be replaced by 2025. This has left us wondering about the cost of changing the heating system.

Has anyone else with electric heat started to look into this? Or has anyone ever done this? Since the heat is in-floor and there are no wall radiators, I assume (hope) that it would just be a question of changing the heat source and not all of the pipes etc. We are also hoping that being in a PPE would allow us to share the cost with the neighbours.

Does anyone have any info or advice to share?

Many thanks in advance!

Re: Replacing an electric heating system?

Is the floor heating water pumped from an electric boiler or electric wires through the floor?

You haven't made that clear although I'm not sure that you know.

Re: Replacing an electric heating system?

If there is a law that it must be replaced, I assume it must be replaced due to the degredation of the insulation covering the copper wires, over time.

In this case you would either leave the wires there and get another heating system, or dig up the floor! As the heating cables will twist across the floor I cannot see them being pulled out and new cables being slipped in, the required tension to pull them out would break the existing cables.

Or, for environmental reasons - the wired heating systems aren't energy efficient.

Electrical heating systems are 100% efficient, the energy does not dissapear, it heats the floor.

Creating electricity loses 30% of energy supplied.

Delivering Electricity loses 30% of electrical energy.

Maybe we should stop selling electric cars as well?

Yes I realize that I am not being very specific and I apologize, but as you seem to have guessed, I'm not clear on the details (perhaps my husband should be posting this...).

But I'm not looking for specific advice either, I'm just hoping that anyone who is or has been in a similar situation (changing an electric heating system) can share their thoughts or experience, regardless of the details.

The law is indeed being passed for environmental reasons, and also part of a plan to faze out nuclear power: http://www.thelocal.ch/page/view/swi...s#.UObnU29fCSo

That is considering a ban on electric radiant heaters. This is not relevant to underfloor electrical heating.

I think you need to talk to a Swiss architect, they do the work here of a building surveyor in English orientated countries.

But you don't need to unless you only have those heaters in the little photo in the article. Is that what you have?

I don't think that's the case, I'm quite sure that it's all heaters or water heaters that rely on electricity. We asked the agent and she confirmed that the heating system will have to be replaced if the law passes.

But that's the boiler. You could have an electric boiler heating water for the underfloor heating.

And if you need a gas boiler then there's the issue of local gas supplies etc.
