Each Oil boiler has good oints & bad points MY personal favourite IS Grant, yes they can leak, but at least they are easy to work on, Just a quick question Why not put the boiler outside then there is NO flue issues? & YES I remember the Harcol 430, & service a potterton today circa 1965!!!!

I am assuming (which could be fatal) you say he changed the oil pump & "EBI" which is the little black box that creates the spark.... did he change the "satronic control box" ( the box with the light on it)??? as usually the control box & Ebi fail together. If memory serves me correct you have...

Personally I wouldnt be messing around stripping the Oil pum down, far quicker & safer just to replace the Oil pump, HOWEVER the oil pump will need to be calibrated to the unit, as NOT all pumps are standard set @ 8bar (115 psi), better to get a competent burner engineer in

Almost EVERYONE does the same thing they get 1 quote then ask themselves "ooh is that too much" get quotes, doesnt matter if its 5 or 6 ...even 10 or 12, just because there is one that is super cheap..oh great that'll be great, but is the tank being disposed of properly NOT dumped in a ditch...

Sounds like a contradiction to me, a "blending valve" is used on domestic water i.e. baths, sinks & basins, to regulate the water temperature (this is now a current law on ALL new builds) So IF the rayburn is running 8 radiators, where would you fit it? as you have a Flow (going to the...

IS there an air bubble in the clear oil line?... could be a few things as the other engineers have stated, IF its NOT going to lock out & continually running without igniting then it could be photocell going "open circuit", depends where in sussex you are as am in east sussex so might be able to...

Just be careful when using a 32mm holesaw asit'll have NO pilot hole so the blade will "bounce" around, little tip, rest the hole saw over the hole that you want to enlarge, mark around it with a permenant marker then twist the holesaw with your hand until it scores the plastic, then use the...

Personally I wouldnt mess around if youre not that much of a plumber as IF you get it wrong you could quite quickly end up flooding the house, tripping the electrics both in the boiler/house, it sounds like a blockage somewhere on the cold feed coming into the boiler, as if you had hot water for...

I used to work for a major oil servicing company, we had a fully stocked van, pretty much everything, from Motor's Oil pump's, Circulation Pumps, P.E.C's, Control boxe's, electrodes (especially inter B9/B11) as they are notorous for cracks, & even a small burner (complete) doesnt matter if it's...

Not ONLY will it soot up, it MAY cause a lot of damage, MOST boilers are only designed to run on C28 (Kerosene) as it is thinner than D32 (Gas Oil) not only that IF you run the boiler on D32 without increasing the Pump pressure it wont atomise the fuel as a rule of thumb the Minimum required...

Simple RED = NOT GOOD!!! BLACK = Good as a rule of thumb it should be on 1 when the boiler is cold, rising to 1.5 -2 when running IF the needle goes over 3 you will hear a "bang-bang-bang" as the Pressure Relief Valve (P.R.V) dumps out the water out, if this occurs it could be the "expansion...

Water doesnt freeze @ 0oC its IS frozen @ 0oC water starts to freeze @ 3oC thats why Frost stats are set @ 5oC

I know First hand how devious Pikies are Went out to a commercial boiler where he'd been hit 3 times, taking 1,000 litres of red diesel First time they disconnected the 10mm oil line from the tank & syphoned it from there, so the company built a steel box over it second time they undid a 10mm...

Gee Sorry I wasnt clear enough for you... so here let me put it in capitals for you MOST OIL BOILERS RUN ON KEROSENE HOWEVER SOME BOILERS CAN BE CONVERTER TO RUN ON GAS OIL,CHECK MANUFACTURERS FOR THEIR SPECIFICATIONI hope that was clear enough for you

Filthy baffles???? then its not set up right :D, & if youre changing the filter every year I'd be getting the tank checked for crud!!! Admittedly just sticking a flue gas analyser in teh gas flue is easier than the servicing of Oil but I was referring to the old gas boilers!!! cleaning the...

Just add my point of view here... so you've repaired your oil tank & it appears to be holding ON THE OUTSIDE!!! & you dont know what is happening on the inside!!! when it fails it'll be when the tank is fullish, so make sure you keep those tanks & pump handy!!!! (& hope that the EA dont read...

yes thats fins Stu, & totally agree with the servicing the car yourself I do the same!!! :D but since you have to call an electrician in these days to change a fuse, I can see why you did the electrics yourself though!!!& the ONLY warranty i'd buy is the Grant Extended warranty ..that appears to...

the capacitor may give you false hope as it may seem like its working o.k for awhile...personally I'd call the engineer in..it's getting close to christmas & you dont want it breaking down over that period & having to remortgage the house for a new oil pump!!!!

Danfoss do a brilliant book which has ALL the conversions in them, or go on their website, a known fault with the wallstar is the clear flexiline ..can you twist it with your fingers? if you can then it can draw air in that way & Welcome to the Oil engineers fraternity!!!

IF there was a "buzzing" noise after lock-out it sounds like a tight spot on the pump OR a bearing wearing, but try the capacitor first, failing that then get a decent engineer in & YES this is a D.I.Y forum HOWEVER there are certain things on ANY boiler that should just be left to the...
