Like some earlier posters I'm going to move my hot water cylinder up into the loft though as it's over 30 years old thought I'd replace it with a new one.
My pumped flow and return to the coils are in 15 mm (the original documentation I have does say 15 or 22), is there any benefit moving up a size, I've never had any problems with recovery times.
Was thinking of getting a Gledhill Enviro Foam tank as compression connections must be easier than the usual fittings. Any comments on these. I have seen some adverts for Gledhill High Recovery Condencyl tanks, meant to be for for condensing boilers but they have much more insulation. Curiously they aren't mentioned on the Gledhill web site which seems odd.
Off topic, any views on plastic speedfit fittings? I wouldn't use them on high pressure or heating but on the low pressure hot and cold? I've had to do some temporary pipework and used them on that, being a bit old I have a luddite distrust of new things but these did seem very easy to use, just worried that when I turn 80 they'll all be leaking past the seals.
Comments on the sizing and Gledhill would be gratefully received.
