Baxi 428 (ErP) LPG Combi Boiler

For homes off the gas grid, the Baxi 428 (ErP) LPG Combi Boiler gives central heating and hot water on demand from bottled or bulk LPG. It is part of Baxi’s 400 series, known for being compact and light to lift onto the wall.

Why fit the Baxi 428 LPG combi

A combi heats water as you use it, so there is no hot water cylinder or loft tank to find room for. That suits flats, cottages and small to medium houses outside the mains gas network. The 428 has separate controls for heating and hot water, which keeps it simple for the householder. Installers like it because commissioning can be done without taking the front cover off, and the main parts are easy to reach at service time.

Common Questions

Can you run a combi boiler on LPG? You can if the boiler is made for it. The Baxi 428 is built to run on LPG for homes off the mains gas network.

What is an LPG combi boiler? A combi that burns liquefied petroleum gas instead of mains gas. Like any combi it needs no cylinder or loft tanks, because it heats water straight from the mains as you use it.

How does a combi boiler like the Baxi 428 work? It heats mains water the moment you turn on a hot tap and looks after your central heating the rest of the time. The 428 has separate heating and hot water controls, so it’s easy for the householder to set.

Will the Baxi 428 fit in a kitchen cupboard? Yes, it’s compact enough for a cupboard from 290mm deep. Your installer should still check the clearances in the manual.

Is a flue included with the Baxi 428? No, the flue is a separate item. Pick the horizontal or vertical Baxi flue kit that the manual lists for your job.

Who can fit the Baxi 428 LPG? A Gas Safe registered engineer with LPG competence on their card, who will commission and register it.

Is the Baxi 428 easy to service? Yes, it can be installed and commissioned without taking the front cover off, and the main parts are easy to get at when it’s serviced.

Before ordering from our Glasgow counter

This listing is for the boiler, so check what flue and controls the job needs and order them at the same time. Make sure the LPG supply and the pipe size to the boiler can carry the gas it needs, because undersized gas pipe is a common cause of trouble. Only a Gas Safe registered engineer with LPG on their card should fit, commission or work on it. Look at the hot water demand in the house too, as one combi suits one bathroom best.
