Hello,
I have recently moved into a property and would be very grateful for any advice on a central heating issue.
The flat currently has a gas-fired rayburn which powers the central heating and hot water. The current hot water system is a vented system with water tanks in the bathroom and a shower pump. There is however no header tank for the radiators, and the primary loop is closed and pressurised. Below is a couple of pictures of the cupboard to confirm this in case it helps at all in clarifying! (Sorry I don't know why they're on their side)
GIven that the Rayburn boiler is thermostatically controlled and is a closed-loop pressurised system, is there any reason that I couldn't use an unvented (e.g. megaflo) cylinder for the hot water?
The mains pressure is good and I know I have to test the flow rate, but the pipe from the cold water tank feeding the hot water is 22mm and is next to the where the mains water enters the property.
I have read that some boilers will not work ok with a megaflo system, but would a gas-fired Rayburn be ok? Annoyingly the existing hot water tanks are about 30cm in diameter so I'd have to think about relocation unless it's possible to get very slimline tanks, but my guess is not!
Any help much appreciated!
