Valve judders the 1st time a tap is opened after heating water up. Presume it's when there is more pressure than usual in cylinder. Air Pressure in expansion vessel at 3.1 bar. Pressure reducing valve is set at 3 bar. Cylinder temp at 50 degrees. This has only started recently after being in 4 yrs ?

sorry. not seen it. Only info is its a 28 Si i am an RGI but never used cc

sounds like the dhw diaphram on way out. \It works on differential of pressure between hot outlet relative to cold mains feeding boiler. as they fail the diffrence required is greater. = more hot flow. to trip the micro switch.

just had a text off a mate with this boiler. Hot water ok but when heating demand it fires a few seconds and fails and trys again and fails etc. cant get there until after lunch so will miss option to get spares after seeing it but could get some on the way if i had a heads up to the fault...

they have an internal air bubble baffle that traps air in the top of the cylinder. the air bubble air absorbs the expansion of water when you heat it up. its required that the air bubble is regenerated every 12 months to stop excessive working pressure, it normally states how to do this on the...

has it dishcharged any water out of the pressure relief pipe.

Sorry the operating system . the screen is blank so unable to do anything other than see curser moving around

sorry for being a novice. Whats that ?

not sure about that make but most have a remote sensor box wired to the boiler for the stat to comunicate with. they often have a button you can press to bring the heating on manually. you may just need to replace the batteries in the stat.

Is the salus stat wirless. ?

The system pressure when the system is cold should only be around 1 bar and lift to no more than 2.5 when operating. You should remove a little out of the heating system and see how it fairs. You can let a little out of a drain off or even out of a rad vent if you catch it into a bucket until...

Hi my daughters laptop last week wouldnt load up. Vaio comes on the screen then the screen just stayed pink. now its only staying dark blue as its about to do something but nothing happens. any ideas ?

Been having this problem since 2011. After 2 sky hd boxes 4 sky engineers over 2 1/2 yrs of frustration another engineer today still doesn't know whats the cause. lounge tv with hd box is never a problem as connected via a hdmi cable and a coax from rf 1 to tv. RF2 goes direct to attic and...

You should be able to undo it and twice round the compression ring with ptfe should sort it. just hope they fitted the inserts in the pipe. Its old class C alkathene

Anybody changed the flowmeter & cable as new wire has different colours and no instructions which to connect to which. new flowmeter has different size connector plug.

If you plan on doing it I'd chose to use compression elbows instead of push it. Well tight with a little ptfe around the rings. The copper double clipped to the wall prior to screed with the pipes live a while to

Hi all . I have a customer with a remaha avanta boiler. It's twice now failed to give hot water and they have remedied this by switching power off then on. Any known faults for this boiler.

Washer is a siemens extraklass xlm 1200.. It fills with water then clicks but the drum doesn't turn Then clicks again but doesn't turn, Put on drain it empties. Put on rinse it empties but doesn't turn. Sould I be looking at the brushes or is it more serious ?.

Sounds like there could be a fault with the programmer but its all about electrical testing which you have to be competent to carry out. need to check voltage at both zonevalves & work back . could even be a bad N connection but if everything else works may not be. Should work independent to the...

Thermal stores are great if you have multiple heating appliances particularly if some don't have thermostat control as stoves, aga cookers etc. heating boilers can be open vent or sealed by another coil. They can be ordered to individual requirements, can also be fitted with twin immersions if...
