OH i'l stand to be corrected. what make of electronic stat did u buy that works without a neutral conection Breezer ?????? the only type i know of are the battery type.

Not sure about that unless rules have changed in last 3 yrs . u were alowed to move an internal meter witihin 600mm of the service valve . if u moved it within 600mm but u couldnt see the meter & the original service valve at the same time then a secondary service valve had 2 be fitted. also is...

Drop the pressure ,remove it give it a good wash out & try it again . often a bit of dirt in the system

Got called to the same problem just before christmas. it was a bristan mixer similar to yours on a worchester combi. the hot water flow was slow enough when working to get the hot water very hot & it freaked out the wax capsule inside that controles the thermostat function of the valve . it also...

the heating timer shouldnt give u the option of heating only so the hot water has to be on 4 the heating to work in summer u will have to turn all the rads off upstairs by the valve on each rad. if the pipework is easy to get to that feeds the upstairs rads you could add a single check valve on...

dont hav 2 b the case. let a tray & trap in to a concrete floor 3 weeks ago . took 2 hrs a 9" angle grinder with a diamond blade & a sds chisel drill & a sh1t load of dust but the means justifies the end if ya fussy. have you already bought the tray as they are available with legs to avoid this.

If its an old stat as u stated with a contacter gap it may only have red & black wire in it live in & live out. Either way there easy to swap only if u do only have 2 wires the new stat will have to be mechanical as well as the electronic type wont work with out a neutral.

If its hot up to the valve it may be the thermostat pin stuck in the closed position. how long since it last worked.

Think i must of gone through 6 or 7 Rothy superfires & they will send a free service kit on request that replace's the spark assembly,adjustment screw & neck if u can get them f"""king little allen screws out. just bought a turbo tourch last month & very impressed apart from it can take up to 5...

Another option to try 1st save cuting into pipework is to attach a hose onto the drain off on the shelf below the pump & open it to see if the tank starts to run. if no attach the hose to the drain off with a jubilee clip & attach the other end to a cold water tap. then open up the drain off...

I know ya getting lots of different options but the safest bet is to ring preston industrial plastics to c if there,s a supplier near 2 u & if not order the fittings off them .job done properly no problems. there's a special solvent u must also use .i think they stock the 1/2" fittings but also...

sorry to go down another root but i'd of put 2 ltrs of x200 descaler in & left it to chug 4 a couple of weeks to see how it faired, x200 can be left in & is a slowly slowly catch the monkey cure. that scale took years to build up it cant be cured over night without a new heat exchanger, c if it...

Its ok the tap manufacture's stating .5 bar taps . i fitted a DEVA VISION last week at home expecting poor flow on a .5 bar rating with 15mm rigid tails on.7 bar head. Yeap its not as good as the bristan mono mixer wife was fed up with but its just about bearable. looks nice though.

£140 not 2 bad as a 15-60 will be £60 so for £80 they may ned to do a part drain & replace valves. As long as thats a fixed cost .

so much 4 benchmark rules on explaining how the installation works.

If that pump is feeding down then the vent & feed are within the correct configaration. If the vent has only been extended recently u may have solved the problem but not given enough time 4 the system to settle down. with the vent lower it is common 4 the vent to run over each time the pump...

SORRY air pressure switch. THINK it a large white plastic one near gas valve on that boiler. or could be a blockage in the venturi on the fan.

unless the system was hot when u took the pictures you could loose a bit off water out of the f/e tank lower the balvalve so to have about an inch of water above the outlet when cold is the pump on speed 1. if not try it on 1 & only increase if you dont get all the rads hot. the valve on the...

have u tried turning off the heating flow & return isolation valves on the outlet of the boiler to rule out a system leak. wont be able to run heating while doing so. I'd get a better engineer before a new boiler. Could do with gazthepottertonenginners opinon.
