new house-dunno how to use boiler help pretty please?

[hayley1986]

hello i have a worchester bosch group 25si boiler, the pressure is too high do i need to bleed the radiators will this reduce the pressure?

also the hot water take ages to comeon and when it does it goes from boiling hot to cold to warm to cole to boiling etc, it fluctuates every few minutes? does my boiler need a service?

this is my first home so have no idea who to ring etc, i dont know when the boiler was fitted but when i looked at the online manuals they say they are from 2002

can anyone help a damsel in boilery dsitress please

think with the si its the one without the divertor valve could be sludged heat ex, hot water sensor etc.would recomend a decent rgi to give a good diagnostic to the prob.if you do get someone let them know its faulty, dont say it needs a service then tell em its faulty when they turn up.a service doesnt mean it will fix a problem.

 

[hayley1986]

thank you for your reply

what does sludged heat ex mean?.

do i call someone out of the yellow pages? i wanted to get boiler cover but its already faulty, i dont want to get too ripped off with cal out charges?

so worried now we have almost no money and havnt even payed our first morgage payment yet

thank again

There were three different version of the 25si.

This is the oldest: 25Si Model Manuals

The two later versions: GreenStar 25si Manuals

thank you i think mine is the oldest (boo)

i got a manual here so lookig through see if it mentions what would make the water fluctuate so much as it can tae ages just to run the washing up, will have to ring round now i think my fella wont be pleased he doesnt like to fix things until they have packed up altogether

would bleeding the radiators help reduce the pressure?

would bleeding the radiators help reduce the pressure?

Yep

...do i call someone out of the yellow pages?

If you must, but avoid the really big ads.
By far the best is to ask friends and neighbours for a local guy they have used several times.

id like to say hot water sensor .dont know what the waters like there but scaled heat ex would cause this prob.

 

[hayley1986]

thank you, i sound so useless, but in my defense i made my own fully operational garden gate today AND fixed a leaky pipe

thank you everyone

 

[hayley1986]

oh i see, do i need aproffeshional to clear the scale out or can i attemp it, or is it more likely parts will need replacing/.

 

[holty]

in all just get some one out. like bengasman has said ask locals for a decent heating eng they have used who works on boilers.

 

[hayley1986]
