Well, overheard someone today saying that they placed the analyser probe in the primary flue for an open flued boiler. When I last did me assessment they said after the draft diverter if possible. Has anyone been told anything to clarify.

Customer complaining on Luke warm hot water. On arrival checked for diverter valve problems. Seemed ok. Plated heat exchanger had been changed two years ago so ruled that out for now. Checked gas rate of meter with hot water demand,, that was fine at 21mbars. Then with water control up high...

Well, I quoted a price of £50.00 to do a landlords, with three appliances. Was agreed, but then got a call back to say they had sorted it for £35.00. What on earth do they do for £35.00. On a second job I quoted £120 to fit a new fire to a solid fuel fireplace. And onto a plugged gas point three...

It bought I had put this on the cc part of the forum. My mistake.

Yes would agree, but I think there is either two faults, or something else going on, since there are occasions where the fan and pump will run but no ignition spark occurring at all, and the boiler does not even get to a rectification point. We have checked the APS and both normally closed and...

Well, customer has the above combi. Think it was last of the non condensing ones. Anyway he had the heating on a small loop and only used the boiler for hot water. Asked for heating to be installed which was done. Everything fine. then, as luck would have it, the boiler then started locking...

Go for a vaillant. Yes gloworm are now part of the same group, but to say they are practically the same is a joke. Just look at the both of the side by side and you will see for yourself.

Well, fitted a new boiler for a customer to an open vent conventional cylindered boiler. Everything was fine. The original boiler was under sized so I fitted a vaillant and set it to 14 kw, 4 greater than the original. The only change to the system I made was going s plan instead of three port...

well, i dont think a 0.5bar drop over 6mths is normal, unless as stated, that the rads have been bleed. does your boiler have a hot water thermostat control on the boiler? does it take longer in the cold? if both old and new boilers were the same size, it should take roughly the same time, (as...

check what wires to the valve are energised that will give you the result you need. the three port valve relies on switched lives on, and a no hot water input to provide a switched live to the boiler. there are numurous flow charts on the three port valve around this forum. If the inputs do not...

The requirements of the conversion course is to have the relevant natural gas tickets and experience. They stated that if they waited for candidates to get the experience on lpg, then no one would qualify. Yes there is an issue with exposure to this type of gas, but I would not take a dump if I...

Thanks. Will get that when they have it in print. To be honest I was really surprised at how much different the two gases are in practice. Best keep the books handy.

That's great. As a matter of interest are you expected to have copies of all these publications. When I did the change over exam there must have been about 10 different publications on the table. It nearly did my head in at the end. Regards.

can someone clear up a question please. I have just done my LPG conversion and we discussed soldering copper fittings. it does clearly say that soft solder cannot be used, but when we discussed the 37mbar low pressure side at the dwelling i am sure they said that lead free would be ok. It was...

the calculation for ventillation needs is detailed in the approapriate regulations. You would need to know max output of appliance, other appliances in the room, extraction influences, adventicious air, and then work out the cross sectional areas of ventillation required.

well returned to a house today (owned by a friend who rents it out to a family). they had complained of poor downstairs heating, and that the system was loosing pressure. Boiler was a Glowworm 30sxi. anyway, had previously discovered that the expansion vessel had failed, so i was going to fit an...

is there a problem with the diverter valve on these. change mine about 5mths ago after it was letting by, now yet again letting by to heating?

god knows, its not as if they are expensive and can be used for other work. it does semm odd which is why i asked. they even come with the gasket kit so its not as if they need to buy extra.

customer wishing boiler change as well as system upgrade. What mid range priced boilers do people like and recommend. 24KW would do the trick. was thinking of keeping it open vent and not system to make it simple. reason for asking, is that we normally put in Vaillant, so would like to offer...
