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.

What size boiler do I need for a 3 bed 3 bath house?

Asked by: Melyssa
Good Afternoon Melyssa, I would recommend you get a Gas Safe installer to your property to do a survey. Boiler sizes are based on your needs for hot water consumption as well as the fabric of your property such as property type, insulation, cavity wall, double glazing etc for the heating. An installer will be able to discuss that with you while understanding your home and requirements, as it might well be for your 3 bathrooms the best solution for hot water might be an unvented pressurised cylinder such as the Heatrae Megaflo.

Would this boiler be OK for a 2 bed mid terraced cottage with 1 bathroom and 5 radiators please?

Asked by: Millard
Good morning Millard, the Baxi 624 combi, has a heat output of 20 kW's for the radiators and will supply 10.2 litres of hot water a minute (as long as your mains water supplies that flow rate in the first instance), which means in principle yes will be OK for a 2 bed mid terrace, if you speak to a gas safe installer they will be able to visit your property and do a heat loss of your property to confirm. Please visit the Baxi website to find an installer in your area. https://www.baxi.co.uk/find-an-installer Kind Regards Paul at Baxi.

can this unit be fitted in my garage

Asked by: fatcontrler
Good Morning Fatcontrier, The Baxi 600 combi range can be fitted in an unheated area such as a garage or loft, as it has boiler frost protection but you would need to consider extra protection for the pipework such as an air/pipe stat. You will also need to consider where the flue can terminate such as through the roof vertically or on an outside wall terminating within building regulations. Kind Regards Paul at Baxi
