There are still replacement parts available for Baxi back boilers, so if you’re determined to keep hold of yours then this is likely your best avenue for exploration.
Also, Why are radiators on when heating is off?
The diverter goes into a ‘mid position’, which allows the hot water to flow to both the water tank and the radiators. When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off.
Is a back boiler energy efficient?
Energy efficient: typically, a back boiler provides only 78% energy efficiency which is below the government’s minimum requirement of 86%. Many modern boilers can achieve efficiency of 90% and more. Cheaper to run: the energy wasted by a back boiler is costing you money.

Why are my radiators cold when the heating is on?
Why is one radiator cold when the heating is on? One cold radiator usually indicates that either there is air in the system or there is a stuck valve within that radiator. The thermostatic radiator valve (TRV), like the one pictured below, controls the flow of hot water to the radiator.
Why is only half my radiator hot?
If only half of your radiator is getting hot, a blocked or closed vent is likely to blame. The steam that does enter pushes the air to one side, and that side never gets hot. Some vents have a flat screw on the top. The screw can be tightened and loosened, and the air escapes from underneath it.
