Advice on smart thermostat/RF

[Harvest Fields]

thanks a lot. The flow is over 22l per minute but I don't know the pressure.

You will not get 22l/m from a 25kw combi boiler.

Oh I don't expect that, but at the moment the pressure is ridiculous and I have a salamander pump!

No problem. You also cannot fit the pump onto the combi also.

Where did you measure the flow from bath taps ?

flow was measured by the plumber from the sink in the kitchen which is right by the boiler.

Yeah, sadly I realised that. This has me a little worried as I would like good pressure in the bathroom shower, instead of this dribling. The shower is over bath. It has a thermostatic bath and shower mixer. The pump has a hot water and cold water feeds, though there is only good pressure when I turn the mixer to hot.

I did not measure it, nor did the plumber. At present it is a gravity fed system with a pump. The hot water pressure at the shower is good, but the cold water is weak. However, next to those is a sink where the cold water pressure is good. Go figure!

i would imagine your cold to the shower could be tank fed not mains as the sink will be the shower feed should be equal pressure on hot and cold or there is a pressure reducing valve on the cold to the shower which has gone faulty or the filter could be blocked.
