Do I have to rip out a working old heater on January 1, 2024?
No. The obligations of the new law only apply if the old heating can no longer be repaired and must be replaced anyway. However, according to the old legal situation, there is theoretically an obligation to replace existing heating systems after 30 years. That was part of the climate package that the old government decided on in the hot summer of 2019. In practice, this has so far hardly been checked. In addition, old heating systems must be checked and optimized after 15 years.
Is it advisable to quickly install an oil or gas heating system?
Experts advise against installing a new oil or gas heating system in a hurry. At first glance, heating with fossil fuels may seem cheaper than installing a heat pump. “But that is too short-term thinking, after all the CO2 price will rise significantly in the coming years,” says Benjamin Weismann from the Federal Association of Energy Consultants. An example: The price is currently 30 euros per tonne of CO2 emitted. Assuming, for example, an average of 55 euros per tonne over the next 20 years, additional costs of around 7,000 euros can be expected for a normal, unrenovated single-family house with oil heating. Many experts assume that the price of CO2 will be much higher. These costs should be taken into account when making the decision.
Which heaters can I install?
In general, the new heating system must be operated with at least 65 percent renewable energy. This requirement is automatically met with an electric heat pump or a district heating connection, under certain conditions also with electricity and solar heating. Hybrid heaters, which also burn fossil fuels on particularly cold days, are possible; they often save expensive insulation. Gas heaters that can be operated with hydrogen and biomass heaters based on wood pellets, for example, are possible, but also subject to certain requirements.
Should I convert to a heat pump even though I don’t have to yet?
Thinking about your own heating system early on is a good idea. “But homeowners shouldn’t rush anything, a new heating system has to be carefully planned,” says Thomas Zwingmann from the consumer center in North Rhine-Westphalia. Homeowners can therefore wait a little longer before buying a new heating system. The prices of heat pumps are likely to fall somewhat in the coming months and years, and newer models are also coming onto the market. In addition: If in municipal heat planning (see below) If it is determined that a connection to district heating is possible, then this could be the cheaper option. It is also important, says energy expert Benjamin Weismann, to first take care of the right insulation in the house. “This significantly reduces the energy requirement. This means that a new heating system can also be made smaller,” he says. Which in turn saves money.
