How to replace a radiator key: useful tips

Why is it useful to replace the radiator key?

Radiator access key May be cracked or worn and become inefficient. This key is essential because the water flow from the boiler enters through it. The radiator is then filled to the top and the water flows out through the detector.

If this key does not work properly, Heating system will not perform optimally We won’t be able to regulate the temperature of the house. That is, the radiator does not heat much or heats very little, causing radiator problems. In addition, water leakage may occur due to wear and tear of parts.

another reason is Replace radiator key This is to place a more modern one. Currently, traditional radiator keys are often replaced by models with built-in thermostats.This device will allow us Adjust radiator temperature And the room it’s in.

Can you replace the radiator key without clearing the circuit?

Not recommended Replacing the radiator key without draining the circuit Because it can be dangerous and cause damage or accidents. When handling the radiator we must be careful to avoid possible damage caused by clearing the circuit.

Replace radiator key step by step

step 1
To replace the radiator key we must have Heating is off and circuit is empty.

After turning off the heating, we close all the air inlets and outlets of the radiator.

Next, we placed a bucket under the radiator and used a wrench to unscrew the cap at the bottom to clear the circuit. After emptying, we put the lid on and tighten it.

Step 2
Now that the circuit is empty we must Release the upper radiator key. With the help of two wrenches, we loosen the hexagonal nuts that secure the valve and remove the part.

To prevent the parts from breaking, we will use another wrench to tighten the first nut securely while loosening the second nut.

Step 3
When replacing a new radiator key, we must ensure that the new key is compatible with our radiator and that the thread diameter matches.

In addition, we have some interesting options on the market, such as faucets with built-in thermostats, which will help us save on heating bills.

Step 5
Once the radiator key is selected, we apply a universal thread sealant internally to improve the sealing and We tighten the nuts In place, tighten well.

Step 6
To strengthen the joint and avoid dripping, tighten the nut with a wrench.

Step 7
When it ends, We fill the water circuit again Let’s check if it’s working properly. As you can see, by following the steps on how to replace a radiator key, you will achieve it very easily.

What tools and materials are needed?

How to choose the right radiator wrench?

The key we buy must be Compatible with our radiators Regarding connection types and Thread diameter to ensure proper fit and performance. Also, it must be a good quality, durable key.

One of the best options we can find on the market today is the thermostatic valve.This key allows Regulate radiator temperature and reduce energy consumption Through valves that can close empty rooms. This way we can independently regulate the temperature inside the radiator.

By installing them on all radiators, energy consumption can be reduced by up to 10%.

What should you pay attention to when replacing the radiator key?

• Turn off the heating: Before working on the radiator we must turn off the heating and close the shut-off valve.
• Clear the circuit: We must clear the circuit to work completely safely and avoid accidents and damage.
• Use the right tools: We must use the right tools to avoid damaging the radiator.
• Protect your hands: We must use protective gear such as gloves and long sleeves.
• Be prepared for possible leaks: When replacing the radiator key, a small leak may occur and we must have a bucket and a cloth nearby.
