i have a new techflow negative head twin-ended pump for supplying a shower (on the same floor as the hot water tank) and a loft bathroom.
when the pump was fitted, i also had the techflange fitted to the tank (drilled in to the side of the tank, approx 3/4 of the way up the tank).
the pump should supply ample water pressure to my thermostatic shower, but for some reason, the hot water supply is only a fraction of the cold supply... as the pump evens out the pressure, when running the shower at a comfortable temperature, the flow is pretty rubbish... when running it cold, the pressure is much much better.
the connections to the tank are 22mm as per the techflow instructions and the pump starts and stops as it should.
any ideas as to why the flow of hot water is so derisory?... could it be due to the location of the flange (towards the top, as opposed to lower down)?
i know that with the techflange, the warranty is increased to 3yrs, which i presume is down to the positioning of the flange in the tank (ie. picking up less scalding hot water, thereby increasing the lifespan of the seals), but tbh, if this is the reason for the waterflow issue, i might have it changed so i can actually enjoy a decent shower.
cheers
