The federal government wants to cap the installation of new oil and gas heating systems in the new building energy law. Classic systems may no longer be installed from 2025. This does not affect stoves. Another law could mean the end here. We reveal what households need to know.
The federal government is planning a radical heat law. Households should convert their systems within the next 20 years. The aim is for all gas and oil heating systems to be operated primarily with renewable energies from 2045 onwards. In addition, from 2025 there will be an installation ban for new classic gas and oil heating systems.
Exceptions and subsidies are provided. But there will also be significant changes in stoves from 2025. Demand here has risen sharply in the last year due to the energy crisis.
“The uncertainty of supply security with gas, but also with electricity, prompts many to purchase a fireplace that works without auxiliary energy,” said Torsten Kiel, foreman of the Saxony-Anhalt chimney sweep guild last November. The savings potential of a single-room fireplace is also a common reason for purchase.
This changes with stoves
From 2025, stoves may emit a maximum of 0.15 grams of dust and 4 grams of carbon monoxide per cubic meter of exhaust gas.

From 2025, the deadlines of the current Federal Immission Control Act (1st BImSchV) will come into effect. You’ll find more about it here. From 2025, stoves and wood-burning stoves installed to date may emit a maximum of 0.15 grams of dust and 4 grams of carbon monoxide per cubic meter of exhaust gas. If these limit values are not met, retrofitting must be carried out by December 31, 2024.
If retrofitting to these values is not technically possible, the furnace must be taken out of service by the same date at the latest. All old systems that were installed between January 1, 1995 and March 21, 2010 are primarily affected.
But there are exceptions. Estimates by the Federal Environment Ministry for 2020 assume that almost four million stove owners will be affected by the regulation. The first deadline of the Federal Immission Control Act applied to wood-burning stoves that were installed before 1984.
They had to be retrofitted by the end of 2017 or, depending on the individual case, shut down. Ovens followed, which were installed by December 31, 1994. They had to be upgraded or replaced by the end of December 2020. Stoves that were installed between January 1, 1995 and December 31, 2010 are now affected.
My oven falls under the regulation, what do I have to do?
The chimney sweep will inform you about the necessary steps. If your system emits more than 0.15 grams of dust and four grams of carbon monoxide per cubic meter of exhaust gas, the systems may no longer be operated from January 1, 2025. In this case, the systems must either be shut down or converted. The chimney sweep in your place of residence can help and suggest necessary measures.
“Retrofitting is possible, for example there are particle filters against fine dust,” explains Frank Hettler from Zukunft Altbau. But not against too much carbon monoxide. “With the old stoves, that doesn’t really make much sense,” says Tim Froitzheim from the Central Association for Sanitary, Heating and Air Conditioning.
This is generally discouraged because retrofitting and then measuring the kilns is often more expensive than buying and installing a new, more efficient system that uses up to a third less fuel.
How much does a new and inexpensive stove cost?
Depending on the type, retrofitting costs from 700 euros. Simple, classic Swedish stoves cost 300 euros in the best case in the hardware store. Up to 1,500 euros are due for the installation and installation of the stove by the chimney sweep. For any retrofitting of the chimney, consumers must reckon with additional costs of up to 2000 euros.
