Pumped shower valves

[Hobo128]

Good morning all

So been asked to install 2 power showers at a property recently... The property has a combi boiler which is only about 3 years old which customer doesn't want to change.... The only option I can see is an unvented cylinder and header tank. Can anyone else see any other options.

Thanks in advance

What’s the fault / complaint?

As Shaun has said what's the issue here lack of hot supply and pressure ? If so then possibly a unvented cylinder for the hot and balanced cold supply to each shower mixer you will need 20 + litres a minute at 3 bar pressure on your incoming supply minimum for a satisfactory result and will require altering quite a bit of pipework? .

No fault. Customer wants a powerful shower which won't happen with a combi boiler. Don't think they've got the incoming mains pressure to cope with a powerful shower and taps, washing machine etc being run at the same time

Depends on the pressure but an accumulator would solve it if it’s a flow issue
