Product Information

As Boilers and radiators are installed by third parties, they do have to install in compliance with regulations and manufacturer standards to get the full benefit of the warranty. All our products are guaranteed for a minimum of 1 year (radiators vary - see individual product specifications, copper tube 25 years) but many offer longer warranties from the manufacturer, which you may need to register for.

So the only difference between the two valves is the orange wire on the downstairs is not going live. The other valve is the same the blue wire when connected to the junction box loses 240v not sure why but red herring i think. On each product, under the specification tab, you will find more information on the guarantee or Warranty. As this information is anonymised and aggregated it cannot be used to identify any individual user actions.I Have tested the wiring from the Thermostat through the wiring centre to the valve wiring where the light brown wire becomes live when thermostat is turned but the orange wire does not go live? I have placed the valve manually on open. I was not getting any voltage reading on pin 10 on the wiring for the boiler which I think is switched live for the boiler. which leads me on to why I've posted this topic. When I put the hot water on, the boiler (a 10 year old baxi solo) will run for about 10 mins before the overheat light comes on, followed by banging in the pipes. I basically want to know whether the 2 port valve may be malfunctioning, causing this problem. I had a BG engineer in but all I got from him was "flush the system" so I want to do some detective work myself.

I have a Honeywell 2 port valve (which looks like a silver box) which is situated close to my boiler. This valve has a small lever at the bottom of it. What I want to know is does this lever move when the valve is in operation? Im sure it used to but at the moment it does not.... If fitted in a confined space, sufficient ventilation must be available to keep the valve within its ambient temperature range and access must be provided to remove the powerhead if necessaryIf the motor is receiving 240v (on the brown and blue) it should rotate the spindle about 15 degrees and operate the microswitch. Sounds like the motors stuffed...they either properly die or partially and don't have sufficient torque.
