When should the thermal bath be replaced? A gas heater should be replaced as soon as it becomes defective or unreliable. Replacing an outdated device can also be worthwhile. New models and technologies such as condensing boilers help save 15% to 30% of energy.

Who pays for the exchange of the thermal bath?If the thermal bath is rented with the apartment and is defective, the landlord must pay for the replacement. In contrast to spa maintenance, which is the responsibility of the tenant.

What should be considered when replacing the boiler?The new boiler must match your chimney. This applies to the minimum and maximum length of the exhaust system, the type of exhaust bends to be used, the minimum exhaust gas temperature and the minimum nominal heat load. In order to obtain these specifications, you need a chimney report. The chimney sweeper will issue this to you for €95. After the installer has installed the thermal bath, the chimney sweep must issue a final report and the gas network operator must carry out a check.

According to EU Regulation No. 813/2013, old, defective boilers must be replaced with more environmentally friendly and energy-saving condensing boilers. In practice, however, you can still use the conventional devices.
