Can I Fit a Shower Pump to my Heating System?

Postby jughustler » Thu Jul 12, 2018 12:58 pm


I would like to install a shower pump to increase the pressure but i'm wandering about the suitability of my system.

I have a modern boiler (not combi) which heats up water to a copper hot water tank, these are located in a bedroom next to the bathroom. I dont know (but dont think) I have a cold water tank in the loft, but most of the pumps I'm looking at say suitable for gravity fed systems.

Is my system suitable for a shower pump and should it be a twin one which pumps the hot and cold (link below)? Also what pressure in bars is considered good?

Many thanks,

Simply Build It

In terms of the pressure rating, it depends on how many showers/bathrooms you need the shower pump to boost the pressure to. Generally speaking, a 1.5 bar rating is ideal for one shower, tap or appliance. A 2.0 bar rating is ideal for two or three showers, taps, appliances or a whole bathroom. You'd need a 3.0 bar rating to boost pressure to the entire house.
