shower pump for just the hot water on pipe for shower

[fizzlealong]

Hi
My mother in law had a power shower and it was with a single hot water pump and the pump was installed on the feed just before the mixer tap and the cold was from the mains, so not near hot tank on the supply to the whole house just by the hot water supply pipe to shower mixer, there was a loft tank for the feed to the back boiler, vented i believe.
So can any body tell me what pump that could have been, as i can only find pumps to fit by the hot water tank with an flange and a lot of messing about and hers was a simpler one.
Thanks

You can buy them from plumbers merchants or direct from the manufacturer.

Yes that would do it perfectly, but my concern is do they work? they are a lot smaller then all other pumps i seen.They also would not haven around when used to shower a my mother in laws, about 20 years ago.

I've no experience of them personally, but there are some good reviews / videos around, and some reputable plumbers merchants stock them.
