Q

01.What costs should I expect with a Greenflow heating system?

The costs are affordable and lower than those of conventional gas systems or heat pumps. They depend on the size of the system, which is why we can only provide price information on request. The installation costs are manageable, as the system can be installed within approx. 3-4 hours – depending on the condition of the heating system being replaced.

02.Which heating systems will be banned from 2026?

– No new oil heating systems
– No gas heating systems in new buildings

03.How long can condensing boilers still be installed?

During the transition period between the start of 2024 and the point at which municipal heat planning takes effect, new heating systems using fossil fuels may still be installed. For cities with more than 100,000 inhabitants, this applies until 30 June 2030 at the latest; for cities with up to 100,000 inhabitants, until the 30th at the latest.

04.When does a new heating system count as a modernization?

Replacing a heating system with a new, energy-saving, modern heating system can continue to qualify as a modernization measure under § 555b No. 1 BGB. The prerequisite is that final energy is sustainably saved, resulting in an energy-related modernization.

05.What does the new heating law mean for homeowners?

The new heating law generally provides that, from 2024, every newly installed heating system must be operated using 65 percent renewable energy. However, these regulations initially only apply to new buildings in a new development area. Heating systems that are still working can continue to be operated.

06.Are electric heating systems permitted in 2026?

Yes, there is currently no ban on storage heaters or electric heating systems. The new Buildings Energy Act (GEG 2024), also known as the heating law, does not provide for a ban either.

07.What is the cheapest way to heat?

To answer the question of which heating system is the most affordable, it is essential to distinguish between purchase costs and operating costs. When it comes to the former, electric heating systems come out ahead. When it comes to the lowest operating costs, among the heating systems considered here it is pellet heating systems.

08.Which heating system is best for the future?

Sustainable, modern heating systems rely primarily on renewable energy. The heat pump is considered the best heating system for new single-family and multi-family homes. Hybrid heating systems have established themselves as the best solution for modernizing older buildings.

09.Do hybrid heating systems make sense?

These are the advantages of a hybrid heating system: they make you more independent of continually rising fuel prices. Renewable energy sources such as sun, air, or ground heat cost nothing. Two heating systems guarantee reliable supply year-round.

10.Which heating systems will be allowed in the future?

In existing buildings, classic gas or oil heating systems can still be installed until probably 2026 or 2028. Even though installing a new gas or oil heating system is permitted, it can be economically risky for consumers. The same applies to biogas or H2-ready heating systems.
