Unvented cylinder size

[Notagainpike]

Also I would recommended sealing the system as the cylinder is in the loft high chance of pumping over

What do you mean by sealing?

Depends where you are. But we’re billing out at £300+VAT per day per man, plus your materials. So it’s probably not a million miles away.

Yeah, 360 a day, what is a plumbers day??
Wheres that abouts??
I wouldnt be suprised by that sort of figure....but 450ish seems crazy in south west

3 days for 1 man?
NO, no soil vent, but there are easy options for discharge i would think...

Yes or 4 if it’s a pain discharge has to be copper or high temp plastic and if over x m it has to be 28mm it can’t be overflow tube

Expansion vessel and filling loop for the heating system instead of a f and e tank

I see. Wasnt going to bother pressurising the heating tbh. At present anyway... is this the best way to go?
What are the afvantages of doing this??

Why high chance of what pumping over??

I would as your having the cylinder in the loft better heat up times customers report and not open to atmosphere so better water quality if flushed

You haven’t much head from the top of the cylinder coil and bottom of the f and e tank at present you have around 2.4m ish with a cylinder in the loft maybe 1-1.5 m max

Sorry boss, you lost me.....am i right in thinking the f+e tank needs raising as high as possible above the cylinder??

Its a bungalow...

Yes you want a min of 2m above the coil of the cylinder to the bottom of the f and e tank
