Hi all,
I am replacing a concealed thermostatic valve shower unit in my ensuite and I'm in a bit of a quandry as to what shower would be suitable. I want to replace it with a new concealed thermostat valve. However the vast majority available (I am looking at Grohe and Hansgrohe) have quite high pressure requirements. I also want one of the large 18cm or bigger drench heads which also require very high pressure (>2bar).
I don't really know whether my boiler system can support that kind of pressure so need to do some measurements I think. The boiler is a Gledhill Gulfstream 2000 - the literature says it can deliver a 35 l/min flow rate at 35c but doesn't give any specs on pressure - other than it is mains water pressure. I am considering buying one of the Monument mains pressure gauges to start measuring.
When the shower manufacturers quote a pressure requirement, is that for both the hot and cold feed independently or the combined feed?
The old valve is still fitted so if I measure the pressure from the valve output will that give me a good indication of the system pressure - accepting that the valve will have some effect on the pressure?
Do I also need to turn on the basin tap at the same time to get flow as opposed to static pressure?
Or do I not need to measure at all and be confident that the boiler is man enough to cope?
Sorry for all the questions but don't want to spend £600 on a shower only to have it barely drip on me!
Cheers
