Re: House with Electric heating

I dont follow this line of thought and I don't think the electrical heating ban will ever come into force here.

For a start Electrical heating is quite economic. I asked about replacing my electrical heating with Gas at the local energy shop and he said I'd save "about 15%" each year max. this with having to get pipes from the road into the house and then pipework all round the house which woudl have been around 40-50k.

Modern radiators have, as well as the temperature sensor: motion detection so they turn on only when people are in the room, scheduling, remote operations as they are connectable to any home automation software plus your electricity to use them can come from Solar or any of the renewable sources.

Therefore you are being asked to replace a green, efficient, intelligent heating source with a heat pump by 2035. The heat pump, bear in mind, isnt any good unless you have good insulation. so an entire house wrapping in insulation along with heatpump install and pipework around the house ? easily into six figures. this is to save the environment of course, which is all that matters, because solar panels clearly arent seen as a green source of energy by the canton.

Bear in mind a massive proportion of heating in switzerland is electric. what exactly are they going to do in 2035, tell people to turn off their heating during winter and freeze to death ?

If you like the house, buy it. the electrical heating ban will not come into force, they are not looking at how technology will evolve.
They are giving people 15 years to come up with something different.

Often, the houses are old and have bad insulation. It's from a time when nuclear power-plants produced cheap energy all day...

If you have such a system, it's time to think about alternatives - because they are expensive and take a very long time to amortize.

If you look at the slides in the 2nd link, you'll see that the difference in the requirements for maximum energy-usage between Muken 2008 and Muken 2014 is just 700ml of heating oil equivalent per sqm.
That's not really a huge difference, Muken 2000 specified 9l vs. 4.8l in 2008.

There is clearly the law of diminishing returns at work here (also, I'm asking myself if and how gray energy usage is taken into account here - fabrication of insulation or cement for a new building is very expensive, from an energy point of view).

Anyway, your thinking is a bit naive: when was the last time reason got the upper hand over a political agenda?
