Running power shower pump off normal HW cistern?

because I want the hot water cylinder to heat back up again after use, as quickly as possible. The immersion is set to 40 deg C, and the cylinder stat to 50, so the immersion only kicks in if the cylinder is drawn on heavily. As a result it only takes about 10mins for the water to be ready for the next showerer.

What about the options of either a break tank and pump, or a large accumulator?

How do the costs etc compare?

Hello Rob

HW via a Surrey Flange from the hot water tank. Cold water via a direct tapping into the cold water storage tank. You're not allowed to fix a pump directly onto a main, it has to come directly from the storage tank.

I'm in the testing stages of mine atm. Done all the prelim pipework, fitted the pump - awaiting january sales for the tiles and suite.

During testing, turning on both HW & CW pump-assisted emptied the cold water tank in 15 minutes. I'm hoping I'm not going to need all that for the shower, or I'll have to be quick with the soap!

OTOH, the bath (also pumped) is going to be very quick to fill...

What size pump have you used?

Regards, Rob.
