I Moved into a house, where the main bathroom has an Aqualisa power shower fitted. The pump is a 654DE 3bar pump. The problem I have is that while pressure is not a problem(its too much really), temperature is a problem. Its not hot enough.
If I turn off the power to the pump, so that the water is just gravity fed, (from the hot water tank which is on the same floor, and the cold water tank in the loft, a floor above), then the temperature of the water is not a problem. Having the selector at the 1 o'clock position, (if goes from 9 to 3 via 12 o'clock) provides the right temperature. On 2 o'clock its too hot! Turning the electricity back on to the pump and even with the selector at 3 o'clock the water is just warm.
So is the pump at fault? I would guess that it was installed around 1997. I have looked at the installation and its as per the manual, with the connection to the hot tank and cold tank, and 22mm pipe work throughout.
It must be the pump, as the temperature is ok when gravity fed. (pump pulling too much on the cold side?)
thanks
