What we think of the Baxi Duo-tec Combi GA

A relatively new range within the company’s extensive line-up, the Baxi Duo-tec GA boiler was first launched in mid 2011 and is a condensing gas combination boiler.

It was introduced by Baxi because it is a lighter model than an older predecessor in the range and places an emphasis on hot water, rather than heat for the heating system. It is a versatile boiler and comes in four output sizes – 24kW, 28kW, 33kW and 40kW – ideal for smaller properties, as well as medium sized houses.

Of note, is the boiler’s ability to quickly heat cold radiators which is great for those people who come into an unheated home on regular occasions.

Another plus point is the size of the boiler, which is just 77 cm x 45 cm x 35 cm, and weighs only 36kg. It can be mounted on a wall, or can also be placed inside a cupboard, making it even more versatile for properties pushed for space.

Getting a Competitive Boiler Quote

Looking for the best boiler price?  If you want to find the best price, we advise you look around.  Get quotes from both local and national installers. Review their price not only on buying the boiler but their installation prices as well.  You want your boiler installation quote to be fixed regardless of any hidden costs found during installation.  Make sure your boiler installer is Gas Safe Registered.  Lastly, look out for any after care insurance deals.
