Radiator Valve Change Kit

Product Information

Let's go through everything you need to know about changing radiator valves. What is a radiator valve? Most radiators have manual radiator valves. They have a range of numbers – normally from 1 to 6 – with 6 being the hottest. By simply turning the valve, you're setting how much hot water can flow into the radiator. Thermostatic radiator valves (TRVs) Unscrew the cap and take off the radiator valve . If you’re not sure how to do it , follow these guidelines: firstly, place some dry towels, sheets or cloths under the valve to catch any dripping water that may be left over after draining and bleeding your radiator. Next, hold the body of the old valve with a wrench while you use an adjustable spanner to unscrew the nuts. Unscrew the cap nuts and remove the body of the valve from the radiator. Use wire wool to clean away excess gunk that may have accumulated on it. Step 5. How to Fit Your New Radiator Valve

This method is perfect for combi boiler systems, but if you have a conventional system (conventional cylinder tank system) you’ll require help from a registered heating engineer. The great thing about thermostatic radiator valves is they're able to detect the temperature in the room. Manual radiator valves can't do this.Before we change the radiator valve we’ll first need to isolate the water supply. When we shut off the water it’ll no longer enter the boiler and this could cause it to overheat and burn out the pumps so we’ll also need to switch of the heating system too! While you can drain a combi boiler yourself, hiring a heating engineer is the better option. And if you have a system or regular boiler then it's definitely worth hiring a professional. 3. Take off the old radiator valve Once you’re happy that the radiator and valve isn’t leaking open up the bleed valve to let out any air that may be trapped inside the radiator. This air will prevent the water from filling the radiator. Valves are essential to keep your radiator working efficiently. Our range includes thermostatic valves, radiator valves, cap kits, and vent plugs in a selection of finishes to help you find the best fit. With a thermostatic radiator valve (TRV), you can control your radiator’s heat level, setting it to the perfect temperature with an adjustable dial. The thermostat dial then closes the valve once your desired temperature is reached.

If you have a combi boiler then you could drain it yourself. Take a look at our How to Drain a Combi Boiler for help doing this. Changing a radiator valve can be a DIY job but we strongly advise getting a professional in. Will the heating system need to be drained? It is important to keep hold of the valve body with the grips to avoid it putting pressure on the pipe causing it to bend and potentially leak later on! Once they’re tight (but not overly done) remove the protective cap from the top of the valve body - this is usually screwed on so simply unscrew it. Now take the top of the valve and connect it to the valve body. Once it’s on you’ll want to just gently tighten up the nut a little, be careful not to over tighten it. If you're using tools to tighten up nuts then you could use a bit of cloth so that the finish of the valve isn't damaged in anyway. To do this, hold the body of the valve with the grips and use an adjustable spanner to make an upwards turn and unscrew the cap nut until water starts to flow out.The easiest way to replace a radiator is to choose one with identical pipe centres. If this isn’t the case, you’ll need to reorient your new valves – it’s best to get a plumber to do this. Step 2 Gather all your equipment, including the new valve, and get ready to bleed your radiator and drain out all water that’s in it. Place some towels or old sheets on the floor around the radiator to dry any leaking water.
