Currently, a lot is happening regarding heat pumps. I recently read a WeLTplus article that stated heat pumps could become the new hazardous waste in a few years. Additionally, in winter—if planning is poor and demand is high—heating with electricity can cause the price to really skyrocket (especially for homeowners who blindly trust the general contractor, because they care less about the future electricity consumption in winter).
On the other hand, the EGG surcharge for electricity for heat pumps is supposed to be removed soon, which could mean that one gets a separate electricity tariff for their heat pump that is then significantly cheaper than regular electricity at present, since it would be without the Renewable Energy Act surcharge.
A lot will certainly happen in the coming years. I don’t dare to say in which direction. I see it similarly to electric cars. One simply cannot say for sure whether the electric car will firmly establish itself (even though our government, overwhelmed by the energy transition, acts like it’s rock solid). The hydrogen topic. Similarly, hydrogen could play a major role in energy supply for single-family homes in the coming years (electricity storage over the seasons?). But since people tend not to know but only gamble—which can also be wrong—I will probably decide on a gas boiler (that has worked very well and cheaply in recent decades, and improvements toward less environmentally harmful gas can also happen). Sure, gas prices can also explode—just like electricity prices, but no one here truly knows.
Naturally, one should plan accordingly so that if heat pumps are the absolute number one in 10-15 years and not, as the article says, the new hazardous waste that consumes a lot of electricity over winter for many, one can also get one (low supply temperatures with underfloor heating and good heating loops < 100 m, etc.). Until then, the gas boiler with its low acquisition costs will have certainly served well!
