Thanks for everyone's help. I was finally able to do a test on the outside tap and got between 24-26 litres per minute so I'm satisfied that the water pressure is sufficient to go ahead with an unvented cyclinder. I don't see the need to have a pressurised central heating system as that seems to...
That seems sensible and very good information thank you. I will measure the flow rate from the outside tap and washing machine valve and report back.
I'm annoyed that neither plumber seemed concerned about my flow rate and only performed rudimentary checks and one of them told me I needed to...
And is there any benefit of me going for the pressurised central heating system? Seems to me that decision is independent of getting an unvented cylinder.
Ok thank you... So if I was going to do it I might expect to have an electric shower put in the en-suite then. I told both the plumbers that I wanted it to do 2 showers but they didn't say anything which is annoying.
Thanks for the reply. I don't know if the pressure was measured. He used a device for a few seconds to measure it.
I thought that the advantage of an unvented cylinder would mean I would get mains pressure from all showers and taps? i.e. In my case 2 showers running up to 15l per minute?
Ok here goes…..I moved into a house in January which has got a lovely new bathroom and nice thermostatic shower. The setup is a traditional vented system with a header tank in the loft and hot water cylinder in a cupboard in a bedroom. There is a pump in this cupboard that powers the shower to...
