Been advised on a previous post to replace old hot water cylinder with an unvented one.
Pressure is good in my area. Any suggestions on what I should be looking for? Make, model, type etc.
I live in a 3 bed, 2 bathroom house with 8 rads. Any suggestions on tank size?
Typical installation costs?, including removal of loft tanks, new pump, timer, stats etc.
Their is this which can be integrated with your existing cylinder to provide mains flow hot water.
A High-flo BZ unit. About £275 and the cheapest upgrade to mains flow HW you will get.
The schematic in this image in the lower right hand corner incidentally has nothing to do with the High-Flo BZ unit.
If your existing cylinder is too small then you could upgrade to this........
A Megalife vented cylinder.
with prices ranging between £600 and £900 for 170L to 210L indirect and direct models.
Manufactured from Duplex stainless steel and 25 year gurantee.
Range also supply these with sizes from 90/L capacity to 300L and should be cheaper than the Megalife.
Now you have the benefit of providing your existing baths with gravity flow from your existing system that you have in place and providing the showers with the mains HW flow.
If you want a fast recovery then you can use a direct cylinder and plate heat exchanger recovery which allows you to downgrade the size of the HW storage cylinder.
DPS will advise on the sizing of this.
I have a cold storage tank in my loft and I wouldnt swap it for a complete mains supply system. And my mains pressure is 4 bar providing 18L/min.
DD will disagree though on this point.
