We’ve all been there: the radiator thermostat is old, stuck, or completely broken. It quickly becomes clear that it needs to be replaced. But the thought of having to drain all the heating water is daunting. Cold feet, a flooded living room, and an expensive plumber visit – no thanks! The good news is that in many cases, a radiator thermostat can be replaced without draining the water.
Radiator Thermostat Replacement Made Easy: Here’s How!
Before we delve into the depths of the matter, let’s first clarify what a radiator thermostat actually is. Simply put, it’s a small valve on the radiator that regulates the water supply and thus the temperature in the room. A functioning thermostat is essential for a comfortable room climate and also helps to save energy.
But how can you replace the radiator thermostat without draining the water? The solution is surprisingly simple: shut-off valves. Modern radiators have their own shut-off valves, which make it possible to stop the water flow to the radiator without shutting down the entire system.
Michael Wagner, expert in heating and air conditioning technology, explains: “By closing the shut-off valves, the radiator is isolated from the rest of the system. This allows the thermostat to be replaced safely and without water leakage.”
Step-by-Step Guide: How to Replace Your Radiator Thermostat
- Turn off the heating: Before you begin, turn off the heating system and let the radiator cool down completely.
- Close the shut-off valves: Turn the shut-off valves on the radiator clockwise until they are fully closed.
- Open the bleed valve: To release pressure in the radiator, open the bleed valve with a bleed key.
- Remove the old thermostat: Loosen the union nut of the old thermostat with pliers or a suitable wrench.
- Install the new thermostat: Place the new thermostat and tighten the union nut hand-tight.
- Close the bleed valve: Close the bleed valve again.
- Open the shut-off valves: Slowly open the shut-off valves again to refill the radiator with water.
- Turn on the heating: Turn the heating system back on and check the new thermostat for leaks.
