Is this what a decent gas engineer looks like 5 star service

British Gas and homeserve do minimal in and out in 10 minutes and the worst thing they charge £110

Power the boiler off and on from the switch, the diverter may be sat wrong..if this doesn’t help you may need a new filling link.. if you already have pressure in the boiler and it’s just you live in a low pressure area so you haven’t the pressure in the mains to get to 1 bar then turn another cold tap on and off fast. The sudden stop of water causes a spike in pressure.. hope this makes sense

There may be a braided silver hose style filling loop somewhere on the system… near the gauge usually

Is there anyway you can definitively test for this back pressure? I have an unvented hw cylinder and 8bar mains cold. The hw cylinder drips after the water heater has been on until hw is drawn off. But also the tundish drips after around 4 hours of no water usage. Combi valve, t&p valve and expansion vessel all replaced, no difference.

@GHancock 3 ай бұрын

You cold put a lever valve on the outlet, top of cylinder and see it you get back feed, but you can also see if it's pipes in wrong… you could install a reducing valve on the mains incoming to the house before any tees see if that stops it

@frankkelly6353 3 ай бұрын

Seems so inefficient to heat one body of water for it to heat another. Also, do you ever get pin holes an fresh an heating water mixing on the secondary plate?

@GHancock 3 ай бұрын

Yes,pin holes although rare, can happen, the pressure in your heating water will go up even without heating and the filling loop disconnected. there are boilers without secondary heat exchanger ie intergas, but in hard water areas you can not simply change the heat exchanger if scaled up. Thanks for watching

Should clean the trap, and set co2 minimum.. but every 5 years make sure you get a full strip down.. but expect to pay more. If it’s left to long the baffle will not come out or burner gasket will fail.

Good video, but how do i add more water please ? My pressure went very low so i re pressured it but now its going right over to the red area. Can you advise please? Cheers Gary 👍

@GHancock 5 ай бұрын

If it shot up to fast.. or shoots up when it heats. The pressure vessel may be gone. If simply you left it open to long then try venting the radiators to bring down the pressure would be the first move

@GHancock 5 ай бұрын

You shouldn’t add more water if it’s going into the red…if you’ve overdone it then you can let pressure out via a pine in a radiator.. if it starts off at 1 bar and hits 3 bar when heated, then the vessels gone and it’s time to bring in a heating engineer

@grahamwilson2748 6 ай бұрын

Great video thanks for sharing Would an option be to fit a separate 3 bar pressure reducing valve to serve the whole house after the Megaflow cold block valve? As a side not would a 22mm non return valve fitted on the hot out at the top of the cylinder stop back pressure problems? Cheers

@GHancock 6 ай бұрын

Yep, a pressure reducing valve on the mains is often the solution, it’s not perfect because when using cold water you are robbing pressure from the 3bar rather than the higher pressure but it is often the solution

@grahamwilson2748 6 ай бұрын

How do you sit on a check valve on the HW outlet to eliminate back pressure? There appears to be two schools of thought on it

@GHancock 6 ай бұрын

Doesn’t hurt, it’s no more dangerous than turning off a tap, it will put a little strain on shower/tap component as the pipe work cools down it may cause a vacuum..but you still need the pressure reducing valve or the higher pressure can cause issues in mixing as the cold dominates

one of the worst designed heat exchangers ever. will never beat the baxi boilers.2.5 mins and your into the chamber.these boilers are difficult, take ages and are maid of ali. salts up all the time. ive no idea why people thing these are the best boilers.

@GHancock 6 ай бұрын

Mainly the CDI and He that built there reputation, but I have a lot of these ticking over at 16plus years without to much trouble, plus Worcester was the first to make a down loading burner whilst all the others messed around with condensing exchanger added to up existing design, I like Baxi too..but I can pick fault with every manufacturer.. so after service becomes the key as well as good manufacturing. Every Engineer has to push the product he believes in.
