Product Description

Manufactured by Baxi, the Duo-tec 33 is a highly efficient wall-mounted gas-fired combi boiler.

How efficient is the Baxi Duo-tec 33?

This is a highly efficient boiler that could help to lower your energy bills as shown by the efficiency rating of 92% and ErP A-rating for heat and hot water.

Is the output rating suitable for my home?

A central heating output of 30.3 kW and domestic hot water output of 33 kW means that it’s ideal for homes with 15-20 radiators and 1-2 bathrooms.

Are any other options available in the Baxi Duo-tec range?

Baxi Duo-tec boilers are available in a wide range of outputs, including 24 kW, 28 kW and 40 kW. The 28 kW model is also available as an LPG unit which is ideal for off-grid properties.

Is a combi boiler suitable for my home?

Combi boilers aren’t suitable for all properties as they can only meet a low to moderate demand for domestic hot water. This is because they take water directly from the mains and heat it on demand instead of needing any additional tanks or cylinders.

How long is the warranty period?

After the installation of a Baxi Duo-tec, you will be covered by a 7 year parts and labour warranty.

What are the key features of the Baxi Duo-tec 33?

There are no shortage of features boasted by the Baxi Duo-tec 33, including user-friendly controls, an easy-to-read display, frost protection thermostat to prevent the boiler from freezing, a pre-plumbing jig, a pre-formed copper pipe tail, built in filling loop, and 1 metre main cable to help for quick installation.

How big is the Baxi Duo-tec 33?

This is a compact boiler that can be installed within a standard kitchen cupboard thanks to dimensions of 780x450x345mm (HxWxD).
