Apparently not. Seeing that you pay huge amounts more than an average family, you either have a huge house, a huge family or some electrical appliances or electricity meter that is very much off.
Do you have a separated counter for the heating usage?
Let's take of 2500kWh for television, dishwasher, lamps and such. Then you are left with roughly 32.500 kWh for the heating, I'd find his acceptable if you live on the Mont Blanc or have the windows open the whole winter.
Either you run things very inefficiently, or the system itself is way to old/very poorly installed combined with very bad isolation, or something is broken.
We have stopped using the dishwasher to save water and electricity (the utility bills cover both electricity and water here). Even worse, the boiler cannot produce enough hot water for shower by our family (3 ppl) in the evening!
What system is used to heat your house? Electrical wired floor heating, electrical panels on the walls, waterpipes in the floor which are electrically heated?
Is your house suitable for solarpanels? A heat pump? With such costs, even an investment of 30.000,- can earn itself back within a very decent amount of years and gain you huge profit in the long run.
A proper dishwasher consumes less water and energy when compared to doing it by hand, if your tap is 15/20 meters away from the water heater you might consider getting a close-in boiler.
You should really get in contact with your utility (couldn't figure out the equivalent of EWZ in Geneva), so that they can send someone to look into this.
That, or the police will show up sonner or later to find your canabis plantation.
Using the Romande Energy facture simulator, for a family of 5 running entirely electric heating on the swiss tariffs the results are 25k kwh per year, relating to an electricity bill of 5.5CHF
Depends on what you call decent, the solar stuff I have seen so far generates fairly low levels of power so took around 15 years to pay off. Is there something more efficient you can recommend (this is a genuine question, not a dig) because if there is something that can pay for itself in under 10 I would be interested.
The amount of years that is needed for panels to pay of depends on a lot of things, is all that can be generated actually used? Can what not immediately is being used be stored (Heat up a large water vessle for heating and showering for example), how much can actually be generated? I am not saying this is the solution for OP, but he should look into it. And maybe the solution would be to isolate the house better, or install a heat pump. Just accepting a bill like this since "yeah we do use so much I think" is to me unacceptable.
so for solar panels, you can buy a battery as well to store up, but even that still ends up with a fairly poor return on investment from what Ive seen. The commune give you some back, which is good, but it still takes a huge amount of time to even pay for itself, by which time technology in terms of electrical generation will have moved on and solar panels might not be the best option.
All the other ones listed are what the canton also say - put in a heat pump, isolate the house all a prohibitively expensive when you look at the actual install cost.
For a family of 5 as it says above around 5.5k CHF is what they expect, so yes they are over and there is something to look at in terms maybe of whether they are new radiators and so on, but they are not wildly over the expected amount, just over by a margin.
Solar panels are - at this time - just a bet that oil will become extremely expensive in such a short time-frame during the lifetime of the panels that it's impossible to get panels at an acceptable price during that time.
Has anyone have the experience of asking SIG to check for the problem similar to mine please? So far, it seems to me that SIG is just happy to receive my regular bimonthly contribution!
