How efficient is the Baxi Duo-tec 24?

An efficiency rating of 92% and ErP A-rating for heat and hot water makes this a highly efficient combi boiler that could help to lower your energy bills.

Is the output rating of the Baxi Duo-tec 24 suitable for my home?

As a combi boiler, the Baxi Duo-tec has a central heating (CH) output and domestic hot water (DHW) output. The CH output is 21 kW while the DHW output is 24 kW. This makes the Duo-tec 24 well suited to homes with up to 10 radiators and a single bathroom.

Is a combi boiler suitable for my home?

A combi boiler delivers central heating and domestic hot water on demand with no need for any additional tanks or cylinders. This is ideal for properties with little space and also means there’s no need to wait for a cylinder to refill with hot water before you can get any out of the tap. However, this does limit the amount of hot water a combi is able to provide. For this reason, they’re best suited to properties with 1 bathroom.

How long is the warranty period?

Baxi Duo-tec boilers available with an extensive 7 year parts and labour warranty as standard.
