Electric shower pumps

[Clarkster12]

does a single pump have to be fitted to either hot or cold gravity or can I fit it to the mixed water coming out of the shower and pump the water straight to the shower head?

Thanks

Single impeller pumps are normally fitted to blended water, i.e. after the mixer valve.
Twin impeller pumps are normally fitted to the incoming hot and cold feeds, i.e. before the mixer.

Check the installation instructions before purchasing. Stuart Turner Monsoon pumps are the best

Many thanks
I have mains cold water feed - i just wanted to boost the hot. am I best to just boost the blended water?

Boost the hot and fit a flow regulator to the cold to match the flow of the boosted hot, so long as the flow rate of your cold is greater than the boosted hot.
