interestingly, most split air conditioning units also have a heating function. Usually, they convert 1kwh of electric energy into 4-5 times the heat energy.
Heating with electricity is therefore something quite achievable and sometimes even economical. At current German electricity prices of 0,33 EUR/kwh electricity heating is currently cheaper than gas heating (currently at 0,20 EUR/kwh for new contracts - was at 0,04 before the crisis).
- MandieD 5y agoMost people here don’t have air conditioners - more than used to, but most of the people I know here (Nürnberg area) don’t. I feel like we temporarily dodged a bullet by sheer laziness - before the pandemic, we were all set to do the whole Energiesanierung with full KfW incentives, which would have required chucking out our oil furnace (replaced right before we bought the house a few years ago) for, most likely, natural gas. Instead, we are still sitting on 1.5 years of normal or possibly 3 years of very carefully used heating oil supply. Now, like everyone, we’re looking into heat pumps. Because we are still sitting on a year or two of heating oil, I think we shouldn’t be competing against our gas-heated neighbors for that changeover this year or next.
