    Worcester Greenstar Heatslave 18/25 oil boiler.

    Its a bentone sterling 50 burner. When i checked the filter i opened the valve and ran off about 1/2 litre and seemed to be ok. There’s a tiger loop on the system which is showing oil. Its 1 of those jobs where the customer says ‘ it worked ok before you serviced it ‘

    Nerrad tapex kit worth buying

    Have this kit. Really pleased with it. The ease of use for removing old taps is excellent and certainly much easier with the ratchet. The only problem I’m coming across lately is that the threaded rods that come with most new mono taps nowadays are to long. So the sockets aren’t deep enough to...

    Tankless water heater ( undersink )

    The open vented undersink water heater you are talking about vents through the tap. But you need the tap that goes with the water heater. When the water heater heats up, the increase of pressure inside the unit drips out of the tap. Like the tap i have linked...

    Uponor underfloor heating valve.

    So only there if the thermostat head on the flow, fails and or if the boiler thermostat fails? Never seen them on a manifold before. Spoke with an electrician who said in the past he hasn’t wired them in. (Not saying he’s right to do that though)

    Uponor underfloor heating valve.

    Hey. That’s for your reply. Must be the sensor faulty then as the thermostatic control on the flow in, was working ok And controlling the temperature. I linked it out last night just to prove there was no other issue. Going back in today to see if the room is up to temperature.

    Uponor underfloor heating valve.

    Can some please identify the valve on this underfloor manifold ( with the black wire coming out of the top). Have an issue where the system is turning off every 10-20 minutes and staying off for a while then coming back on again. The room can’t get up to temperature because of this. Power was...

    Baxi 624 system boiler

    Is this the jig which the boiler hangs on?

    Baxi 624 system boiler

    Switch the black return valve off under the boiler and there’s a nut to undo. On the Combi is where the filling loop connects to usually.

    Baxi 624 system boiler

    The duo tec has that gauze filter On the return. Never realised till technical told me. Check them all the time when servicing now. Doesn’t take much to block them.
