I had a completely new S plan pressurised central heating system installed 6 months ago with new rads, pipes and boiler. Ever since it was installed, its suffered from reverse circulation with the upstairs rads getting warm with the HW switched on/CH switched off.
The only way to sort this problem properly is to remove the HW cylinder and re-pipe the connections. It has been suggested by the plumber that it can be resolved easily by installing a pressure relief valve which will negate the need to remove the cylinder. I'm not so sure about this proposal and whether I should be accepting this on a new installation. It sounds a bit of a bodge and something else to go wrong? The prv will be under the floorboards. What do you guys think??
Anyway, thanks to all in advance...
