You heat and heat, but instead of the temperatures, only the heating costs increase. What reasons could be responsible for the fact that it just doesn’t get warm?
Leaky windows and doors
Leaky windows and doors could be a reason why the apartment doesn’t get warm despite sufficient heating. Due to moisture, the window seal can wear out and leak. Incorrect adjustment between the window sash and frame can also cause cold air to come into the apartment. If it doesn’t get warm enough in the apartment, it may be worth checking the windows and doors for leaks.
Air in the heater
If you don’t vent your own heater regularly, built-up air in the heater can also cause the heater to not work properly. Usually this problem can be solved quite easily by yourself. Thermondo gives a detailed overview of the best way to proceed with ventilation: First of all, you should turn off the radiator completely. You should then hold a container under the vent valve to catch any liquid that may escape. The valve should then be carefully opened with the bleed key until heating water emerges from the valve. The process is now complete and heating can usually resume normally.
Stuck valve pin
A stuck valve pin on the radiator can also prevent the radiators from getting sufficiently warm. An article on Heiz.de gives precise instructions on what needs to be taken into account when solving the problem: First, you should start by carefully loosening the valve pin, ideally using a small hammer to gently tap on the side of the valve. If the pin does not pop out on its own, you should move it minimally with a pipe wrench, being careful not to pull it out completely. As soon as the valve pin protrudes by about five millimeters, the instructions say you should lubricate it with grease or oil to restore mobility. As soon as the valve pin moves smoothly again and pops out automatically after being pushed in, the repair process is complete.
Flow temperature too low, summer operation, hydraulic balancing
According to an article by Peter Barth GmbH, a master craftsman for heating and plumbing, a water supply temperature in the heating system that is too low can also cause problems. According to the article, this could lead to the radiator not warming up properly. There could also be problems with the hydraulic balancing, which results in the heating remaining cold. According to Peter Barth GmbH, it can also happen that the radiators are still set to summer mode when the heating season begins, which means that they also remain cold. In these cases, Peter Barth GmbH recommends contacting the landlord or property management company.
