Hello folks
We've just moved into a completely refurbished bungalow. It's 3 beds, a little over 1000sq ft. A completely new heating system was installed, using a Worcester Greenstar 37CDi Combi. I can't pass comment on the CH system, but although the HW works fine at the taps it is impossible to control the temperature of the showers with the mixer valves, veering from hot to cold all the time.
Having searched through these forums for this issue, I have drawn the conclusion that it's unlikely to be a boiler fault on this brand new system, but could be one of the following:
1) Too much of a pressure mismatch between hot and cold at the shower mixer valve.
2) Not enough flow rate through showerhead causing boiler to constantly turn itself off and on.
3) Oversized boiler, resulting in it going constantly off and on same as (2)
The HW temp is currently set to 'e' on this boiler - which is the setting between 4 and 6. This may mean something to someone familiar with these boilers. I presume the 'e' means this is regarded as the most efficient temperature to set to.
Any comments or advice welcome. Thanks.
