Rated 5 out of 5 by from Plumbing and heating engineer Well made quality little boiler I have fitted a few of these now and they are my boiler of choice I always recommend them to my customers.

Rated 5 out of 5 by from Nice Had to replace an old Worcester boiler. Really pleased with how this one is performing so far. Easy to follow instructions and the flue system is very easy to fit. Not as heavy as the old one so this is a bonus when mounting on its bracket. Self purging at start up but you must follow the instructions on how to do this. The integrated filling loop is easy to assemble and install. Can't give 5 stars all the way as it has only been in a week. For the price this is a cracking boiler. Tips. Read the instructions on how to purge the system at start up. Assemble the filling loop and install loosely befor fully tightening.

Is it suitable with Underfloor heating

I have a 2 bed ground floor flat being renovated. Will this boiler be sufficient to service underfloor heating in the kitchen, Living room, bathroom? Rads only in the bedrooms.
Asked by: Marsha
Good afternoon Marsha, yes no problem at all. It works with underfloor heating and the Kw for the heating side is an output of 20kW so should be sufficient no problem. Kind regards Paul at Baxi.
