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.

Why do thermostatic shower valves fail?

There are several reasons why the cartridge may have failed; the number one cause is an in-balance in water pressure between the mains cold pressure and the heated hot water(and this is very common). This constant in-balance between the two will cause damage to the cartridge which is housed within the valve.

Why does Drayton 4-MAX radiator never heat up?

Only when they are manually turned up (4-max) does the radiator heat up, but then they shut off and never kick back in even though room needs more heat. They are effectively acting as manual valves not trv’s. I have tried the special balancing key and although this restricts flow, once the valve shuts off it doesn’t kick in again.
