Conclusion Best Buy in minutes Get your fixed price Trustpilot Heatable is authorised and regulated by the Financial Conduct Authority (reference no. 805259). Could I save a small fortune and fix it myself. Yes, replacing the Pressure Release Value turned out to be pretty easy. I don’t know very much about boilers myself, but I am generally good with mechanical things. Some of this advice could be very, very bad. All I know is that it worked for me. I accept no responsibility for any consequences of anyone following any advice on this page! I needed to top it up about once a month, but in December 2005 it was getting serious. Over the Xmas period I had to top it up once per day. There aren’t that many reasons for this in a central heating system, so I availed myself of the Sealed Central Heating System FAQ. Read it. Now! Usually this is actually in the boiler, there certainly is one in the WB240. No wonder I was having to top it up a lot! The Sealed Central Heating System FAQ which you read earlier explains this. To test whether it’s the expansion vessel or not you will need to find it. This isn’t difficult. It’s a large red thing. Follow the instructions below about Opening the boiler up. Ergo leaking PRV. Flushing it through wasn’t working so it had to be replaced. They’re not the cheapest on the web, but their delivery is good and they’re not too far away so a visit isn’t out of the question. The valve in question is order code 108151. WB Part 8-716-142-416-0. It arrived the next day despite me picking the 2-3 day delivery. Then isolate it electrically. Somewhere you should have some means of actually turning the boiler’s electricity supply off. This may be near the boiler or near your main electrical distribution board. It could even have its own RCD (switch) in your mains electrical distribution board. When the boiler is powered down there should be no lights on. This is the gas pipe. Turn the screw so that the slot faces across the pipe.
If you can’t figure out how to do this yourself then you’re in trouble. Call a professional! Not the ones facing you, the ones holding the grey control panel to the flanges at the side of the boiler. Supporting the grey control panel from the bottom, undo these screws. The whole control panel unit will then pull forward and hinge down. Note that the actions of pulling it forward and dropping it down are somewhat simultaneous. The Sealed Central Heating System FAQ details how to test it. Mine had plenty of pressure in it. It’s right up the back of the boiler. How convenient. With the control panel dropped, I managed to get my left hand in under the “white thing” and over the top of the PRV so that I could operate the valve. Turn the top towards you, you will hear water escaping. Keep turning it the same way. Eventually it will snap back to the closed position. Hopefully some clever spark has installed a pair of isolators other than the boiler’s own ones. If there is another pair, use them. If not, the two leftmost pipes on the boiler will have isolators on them at the bottom of the boiler. Turn them so that the screw slots face across the pipes not along them. They may leak a bit, so beware. Unless you plan on getting very wet whilst your working, draining the boiler is a good idea. To do this, just tweak the PRV so that water is flowing down the release pipe and leave it until it sounds like it’s empty. If you look just to the left of where the water pipe enters the PRV, there is a slot cut in the panel. This exposes the nut that connects the PRV to the pipe that extends leftward. Don’t do that quite yet though. First, undo the nut that connects the PRV to the waste pipe. If you’ve ever worked on a Citroen, this will be small beer to you. If not, just persevere. There’s very little room to work the spanner and you have to be very patient! It’s still connected via a thick piece of copper wire to the pressure gauge at the front of the control panel.
Undo this, then the PRV is really free. If you’re feeling brave you can test it once and for all:- I turned it to make sure it was shut, covered the pressure gauge socket with my thumb and then blew through it. The problem being that I did in fact blow through it. These gauges are supposed to open at 3 bar and there is no way I can provide 3 bar of pressure with my lungs! I added a bit of PTFE tape to the threads. It’s probably not required and may make matters worse, although I can’t think why. This is what I did and it worked. You will hear the boiler gurgle a bit as (some) water flows back in. Then cause demand from the CH system (select Heating and Hot water and then tweak the controller until the boiler attempts to fire up). Clearly the burner will not work, but everything else will. It will attempt to pump water round the system. If the pump makes a horrible noise, check its temperate. If it becomes uncomfortable to touch, turn it off and wait until it has cooled down, then give it another few minutes. Eventually the boiler should sound pretty much like it did before, but without the burner running, obviously. This is the strange little button on the top of the control panel. It should be pressed in. If it pops out the boiler will stop. If this happens, turn off the gas and run it for a few more minutes without the gas on, then give it another go (you will need to press the reset switch in again). There is a bleed nipple on the pump, there may be one on the heat exchanger, too. Unfortunately I don’t know anything about this. If you do (or manage to find out) then please let me know! Turning on a hot tap will correctly turn the boiler on, but (sometimes) after the hot tap is turned off the boiler continues to run and will not stop. British Gas has replaced many parts on this unit, but still the problem persists. Any advice would be greatly appreciated. Thank you.

It’s a long sequence of digits and letters found printed on the side or on a label pasted on its drop-down front panel. It’s not like the manufacturers make it easy for us to decipher those serial numbers. In most cases the boiler manufacturing date will be coded and hidden somewhere within the serial number. Your best point of reference is the Building Energy Performance Assessment site who have a very convenient boiler database. Select the fuel, type, brand and model and then click on “details”. It will give you the first and last year of manufacture. Of course, it’s not a very accurate way of telling the age of your boiler so let’s hope we’re looking at one of the main brands. Dating their products is relatively easy. So how can I find the age of my boiler. Let’s look at some of the most popular brands. Luckily, the manufacture year is always the fourth and fifth characters. For example this serial number: If you run into problems, you can check this page for reference. Their serial numbers were designed for internal use. So, if you need to tell the age of your WB, you’d need to contact their support team or phone in on 0330 123 3366. A serial number on a Vaillant will be between 20 and 28 characters long and in most cases the 3 rd and 4 th character will represent the manufacturing year while the next two characters will tell you the assembly week number. This means our boiler has been assembled around June 2001. The most popular Ideal Logic range will have a 24 or 25-digit number preceded with a two-letter prefix. It is conveniently split into 3 sections.
Starting from the 16 th or 17 th character you have a 4-digit code representing the year and the week of production. Then the last 6 digits represent the production date. It’s neither the UK nor the American way.Its serial number is shorter. It consists of only 17 or 18 characters. You’d be looking for the 3 rd cluster that contains 4 digits; and it would represent the year and week of production. Its age is coded in the serial number as month and year rather than week and year. For other Ideal models, please get in touch with their technical support. If you come across a more obscure boiler and you struggle telling its age, please get in touch and we’ll see if we can help. Get a new boiler quote now: Feel free to contribute!
