I love the way you analyse this so you give the power you do not need to the energy system and get paid? We have solar panels in the new house, also had them in another one just to make sure we have warm water between March to October and no need to fire up heating at all.
My aunt has installed more and sells surplus but regrets it as she is now officially and entreprenuer and tax system is as any other thing complicated in Germany :-).
This does not have any tax impact on us as it just gets offset against what we pay for our energy. I need to see if the payments need adjusting to keep us in credit through the winter. I could use some of the excess for water heating, but we have more than enough for that. The house heating is currently on gas, but I may look at a heat pump at some point.
Have you posted about your system? I want to see what benefits solar brings to different people.
!BEER
I did not post about the system - I actually have it in the cellar and as long as it works I do not really think about it :-). But I might take a deeper look into the specs sooon and let you know. House heating also on gas right now, with solar we jsut do not need that much which is good. In Germany they wanna get rid of all gas / oil stuff and support you buying "Wäremepumpe aka heat pump" but still it would cost most house owners addition 40-60k€ and I am careful to spend that much money yet .
I'm sure Germany wants to get off dependence on Russian gas. Heat pumps should cost a lot less than that, but it will depend on what other equipment you need. Here there is a government grant to cover some of the cost.
just checked again the government program - they pay 40% for the system (if meets requirements whch is typical German admin language) - so it could work out with 30-40k - but in a nutshell makes only sense when gas system is old and has to be replaced anyway - now not really an option I think. We will see :-)
We can get a £7500 grant and Octopus says it would only cost another £500 for the heat pump. Actual cost will depend on other factors, but I would want to get an proper quote. Our boiler is getting on a bit, so I will consider it when that needs replacing.
Yeah many factors and many different sources that tell what it wil / could cost dpeending on certain factors - here a ballpark screenshot (In German)
Rough translated (but all depends on "factors" :-))
How much does it cost to convert a gas heating system to a heat pump?
Converting a gas heating system to a heat pump costs between €25,000 and €50,000, depending on the output and type of heat pump. The purchase costs for the heat pump are between €20,000 and €35,000, up to 40% of which is subsidized by government grants.
The total costs for the gas heating system are calculated as follows:
Cost center of the conversion Costs
Disposal of gas heating € 2,000 - 3,000
Purchase of heat pump 20,000 - 35,000 €
Installation of heat pump incl. accessories € 3,000 - 12,000
Total costs € 25,000 - 50,000
I could read the German :)
Maybe the German market is different to the UK, but costs here seem much lower. Looks like an opportunity for someone to offer a better deal.
True, independent frpm Russian gas and we also get support by government but my calculation still says we need to spend privately in addition around 40-60k - that is not doabel - we will see how the next election will end and what is new then
