Baxi Duo-Tec 28 LPG (ErP) Combi Boiler

Already converted from the factory, the Baxi Duo-Tec 28 LPG (ErP) Combi Boiler is the boiler-only version for homes running on LPG. It heats the radiators and gives hot water on demand, so there is no cylinder or tank to house.

Who the boiler-only Duo-Tec 28 suits

Pick the boiler-only version when the existing flue can be reused, or when the job needs a vertical or extended flue rather than the standard horizontal kit. It also suits installers who prefer to choose their own controls. The Duo-Tec 28 is aimed at medium to larger houses with up to about 15 average radiators, and its display is clear enough for the householder to use without a manual.

Common Questions

What is the difference between the boiler-only Duo-Tec 28 and the kit?

The boiler-only listing has no flue or clock, so you pick the flue and controls that suit the job. The kit version adds a standard horizontal flue and a clock.

Is the Duo-Tec 28 LPG converted at the factory?

Yes, this version comes set up for LPG. It still has to be commissioned on site by an LPG qualified Gas Safe engineer.

Does a combi boiler work with a hot water cylinder?

No. A combi makes hot water straight from the mains on demand, so the cylinder and loft tanks usually come out. If the house needs stored hot water, a system or heat only boiler is the better fit.

Checks before you order in Glasgow

Confirm the flue route first and order the right flue kit, because one does not come with this listing. Make sure the gas pipe from the LPG regulator to the boiler is big enough for a 28 size combi. Use the pre-plumbing jig to get the pipework in place before the boiler goes up, which saves time and keeps the boiler out of the dust. An LPG qualified Gas Safe engineer must install and commission it.

If you would rather have flue and clock in one box, a kit version is listed alongside the Baxi Duo-Tec 28 LPG (ErP) Combi Boiler in our LPG boilers range.
