Only ever fitted Salamander pumps before. About to do a large project including a new bathroom with shower room. I figure it will be easier to fit a 3 bar single whole house pump to pump the hot water than it will be to fit and plumb a separate shower pump. I was thinking of using a Stuart Turner one as I've read that they are quieter than the Salamander ones. What do people think that have installed them re build quality, noise etc, compared to Salamanders?
