    Hi,

    I’m after a bit of advice please.

    I recently found a Gas Registered small firm to come and service my Boiler and Mega Flo.

    The chap turned up and his gas safe card showed he was qualified for all the aspects he was undertaking.

    My boiler is a Potterton, last serviced about 18 months before by British Gas, It doesn’t have any labels on it confirming which specific model of Potterton it is (30-100). I pointed this out to the engineer and he said not to worry. However on inspection of the paper readout he didn’t check the gas burner pressure. Each model of Potterton has a different gas pressure requirement. I subsequently emailed the company and they have responded saying he identified it as a 40L and the gas pressure was 11.8 so was in tolerance. But this isn’t on the read out of paper I got from the engineer.


    Also he serviced my megaflo as the water pressure in the house is not great, all this involved was him opening the PRV, which improved the water pressure for a second or two only for it to drop back down. I’ve subsequent found online the correct way to recharge the air gap, by opening a tap on the ground floor and draining the whole tank. He did suggest i replace the cold water combination valve.


    Finally I asked him to look at a TMV for conservatory underfloor heating, I had to answer the phone, while he was unscrewing the top of the TMV, he subsequently left and when I went to look at the TMV, it was weeping.


    I’m subsequently being charged £185 for this service, but don’t feel like anything has been carried out correctly? Am I being too fussy, has everything been done correctly?


    Thanks

    Ask them to send a different engineer back out.

    Can you clarify what you mean by rate?

    Is there anything on the paperwork that says kilowatts? Or KW

    Gas rate of an appliance is the amount of Gas it uses in an hour. Usually this would be calculated at the Meter.
    How long was the individual on site?

    Yes, it is rated at 11.8KW.
    He was on site for about an hour.

    It sounds like he did Gas rate it and found it to be using around 1.4 M/3/Hr which is roughly 15Kw input (11.7 Kw Output).
    Hence the identification of 40L. The 40L is 40000Btu/hr output.

    Some of us do both Burner Pressure test and Gas rate but you do not need to. You can look at flame picture, flue Gas analysis etc along with Gas rate checks to confirm that something is burning correctly.

    The Gas rate information will not be on your read out copy if that was from his analyser.

    The other things you mention I cannot comment on without having witnessed them.

    Ask them to come back and explain it to you if you think there is something wrong.

    for a megaflo recharge you do not have to empty the cylinder the instructions are on the side of cylinder for you to be able to do it yourself , if we had to empty the cylinder fully it would take over another hour to empty and fill so your charge would be more.

    Having run many fitters over the years I would consider it fair to be invited back to rectify the problems. If they refuse or don’t turn up then ...release the dogs of war. Rob Foster aka centralheatking

    Did you ask the price before employing them?

    It’s only my opinion but sometimes before handing the customer a piece of paper it’s better to explain what everything means.

    Then the customer understands what’s been done.

    Amount of times I’ve gone to jobs and there’s no paperwork or record of work carried out its annoying it’s like the blind leading the blind.

    Hi Scott,
    Yes, I got a quote before hand and was happy with the price at the time, but unaware how little was involved in ‘servicing a megaflo’ with no improvement to the pressure. (There are no instructions on the side of my cylinder)
    Also I wasn’t expecting him to leave a leaking Tmv.
    It was why I wrote this post as I wanted some advice on if the boiler had been serviced correctly.
    Thanks all who have posted!

    Not a lot in servicing an unvented cylinder. But strainer in combi valve should definitely on the list.

    As for the post in general then I believe you are both at fault. He hasn't explained fully what he has done and you haven't asked enough questions to him. After all its your coin you are spending.

    Difficult to come onto a forum and ask about what he has done/not done when only you and the service engineer are present.

    At least with the leaky tmv it's easy to get them back. Just have a list of questions.

    Oh and include the strainer.
