howaya lads ! first post here but reading through the previous threads im confident of finding an answer !

basically i recieved a call out to a problem with a rad , arse of it completely corroded so had to fit a new one ( heating pipework is all mild steel , but thats a seperate problem ) . problem is the client complaining about fuel consumption from his appliance . he thought he might have a leak somewhere on the oil supply line , but its all accesible and no sign of a leak. i noticed the boiler is a dinosaur and have never come across one like it . its called a "berton ,serie canada ,mod. brev " . just by looking at it i can tell its waaaay oversized. flow and return connections are 2" .  found out the man that built the house around 50 yrs ago owned a factory , so i reckon he took the boiler from there . its a average sized 4 bed bungalow , 10 rads. i advised the client , but would really want some info on this boiler to back up my claims . i cant find anything on the internet . has anybody come across this boiler before , any help would be great as im hoping the client will opt for a HE condensing boiler changeover .

thanks again  !

Nearest I can google is BERTON CALORTECNICA in Italy.

If the house is 50 years old might be a lack of insulation as well as an old boiler. How much oil is he using?

@ CW ... loft insulation is perfect , only redone when they moved in . as for cavity/wall insulation i doubt its up to scratch . id say the pipework isnt helping matters eitheir as the little bit accessible to me was in very bad shape due to corrosion . but unfortunatly he put in all new floors before addressing this problem .

ive advised him of this scruff but hes hesitant because of money etc . very hard to advise people over here these days  as the majority of people assume u are just trying to rip them off . sign of the times unfortunatly.

See if the local fire brigade will give him a Carbon Monoxide alarm

The good o'll oil boiler.
