    Megaflow Air Bubbles

    Yea yea...but I may have found the..or at least an answer to this one. Its a downstairs cylinder and they keep trying to regenerate the air bubble using a hot tap which is no lower than the cylinder and thus the bubble in the cylinder never gets replaced. I'l drain from cyclinder drain cock...

    Megaflow Air Bubbles

    I'm familiar with the loss of air bubble problem on Megaflows. Is it ever curable without installing an external PV or is that simply just the way to go for a permanent cure. Client needs convincing, and I don't do or see enough of these things to be authoritative on whats best to cure it of...

    New boiler installed on an old system. Bodged job?** PICS **

    I think most people on here are bang out of order. You do not try and take it out on the customer under any circumstances for using a scheme such as Warmfront. If you have dirty linen you want aired because you have a chip on your shoulder about the scheme then do it within the industry where it...

    New boiler installed on an old system. Bodged job?** PICS **

    You old skinflint. Are you so green that you don't keep a few pennies in your pockets for just such eventualities, In social housing this comes up now and again so you just give them 1p for the electric you used. What are they going to do...complain. It certainly shuts them up. Alfredo

    Correct order of application for central heating treatments

    Just look into each tank..then ask yourself..which is the one which contains the water I bathe in.....yup..its not the grotty dirty water in the little tank. Thats the one you tip all your foul chemicals into. The missus will not be impressed if you start tipping them into the big tankr as it...

    Barn Conversion , combi boilers?

    Depending on how far from the hot tap your combi is, the hot water is rarely if ever instant, so the good lady might be disappointed in the 30-40 second delay getting HW at the tap. You would get just as 'instant' hot water from a cylinder. As others have said, a combi will only work as long...

    Grundfos JP4 and JP5 booster pumps...noise

    Well..the answer is to install the ejector valve in position one, and to throttle back the outlet regulator which reduces cavitation and keep flow rate at around 16-18 litres/min...which is more than adequate. Its still noisy, but a lot less noisy. Not that anybody is interested :mrgreen...

    Grundfos JP4 and JP5 booster pumps...noise

    Customer had a JP4 pump (This is a water supply lifting pump to supply a roof tank from a private water tank in a field fed from a spring), nice and quiet and then it leaked. He bought a JP5 and got another plumber to install it..its VERY noisy. Other plumber is unwell ( he is a friend so its...

    Help, Can i create a new controllable heating zone!

    If its only two rads in an extension then you could do a lot worse than just fit two programmable TRVs like Pegler I temps. They are about £30 each, no pipework. They say batteries last two years.....but i've heard that could be a low as 6 months....so somewhere between six months an 2 years you...

    Best settings for room thermostat, TRVs and boiler stat?

    If rads are too hot to touch boiler stat is too high...or broken. I've been in enough houses where the boiler stat is on so high the occupants cook as the radiators almost glow, then turn off the heating, then freeze, then turn it on again, then cook etc etc. Its crazy and wastes masses, and its...

    Best settings for room thermostat, TRVs and boiler stat?

    The first thing I'd suggest is to open all TRVs to full, room stat full up then adjust your boiler stat to a position where all rads get hot, without being outrageosly hot. Your mexico has a big old cast iron Heat Exchanger that requires quite a heat input to get heat out. Turn the boiler stat...

    PTFE on compression fittings?

    We know what the manufacturers say. They tend not to give guidance on fittings that are less than pristine. As I said the general rule is against using PTFE or sealing compound such as Jet Blue..but then what happens when you obey the rules as laid out by the manufacturer, and your joint leaks...

    NTS AR ID

    I think if you were able to find a cocktail of even minor deficiencies I'd go straight for AR, but we weren't told of any deficiency in the way it passed throiugh the ceiling. Now if there were marking on the ceiling due to excessive heat...different story altogether, but on the use of incorrect...

    Potterton Flamingo 20-30.

    I've worked on a few of them, and what John says is fair comment. The Flamingo is/was a good quality boiler, but its really in its end of life phase..which doesn't necessarily mean its knackered, but it is getting old. The only things you might need are thermocouples and these are freely...

    NTS AR ID

    Unsafe Sits Guru he say: "If Grasshopper find incorrect use of flue material .e.g. exposed flue liner, it NCS" I'd add subject to flue passing all of its tests. As long as its working safely you can leave it. Alfredo
