So bought house last year. Boiler is at end of garden, oil fired central heating system. House was bought from a local plumber so assumed all was ok. Was told boiler was recently installed. Ran out of oil so when system was switched back on it wouldn't work. Called out heating engineer who said it was probably air in pipes. However found whole raft of problems with boiler including fact it was running off test switch as was incorrectly wired and that cabling was unsafe. It should be proper armoured cabling, mine was not. boiler is against fence, there is no way to service boiler in current position and the condensing pipe is not correctly sited. There is also no fire valve shut off in boiler. All in all will cost about 600 to fix as need to move boiler and run new cabling. Original owner not often registered. Is there any way I can get money out of him. I am furious as each time there is a problem with the plumbing it turns out that he has done a cowboy job that costs me loads to sort. Any ideas?
