    Is an £800+ power flush the only option?

    We have an open system oil-fired boiler (fitted we think in 1998 when the house was built) with a hot water tank in the airing cupboard and cold water tanks in the loft. Separate honeywell zone valves each for hot water and heating. We moved in last year, had the boiler serviced last year and so far it has been trouble-free.

    We turned the heating on Sunday and found that the odd radiator got warm but most were stone cold. I set the heating to come on morning and evening, and some radiator got a bit warm and others didn't. This morning one or two of the radiators were positively hot, but most were not. All the thermostatic valves were opened to maximum.

    I was having the heating engineer in today to service the boiler (which passed as far as possible, clean as a whistle) and he checked the system. No radiators heated up at all after he switched the boiler to constant and turned up the thermostat. There is hot water from the tank to the pipe underneath the first radiator, but nothing is getting through. He took off the thermostatic valve on that radiator, checked it worked (which it did) but nothing was going through into the radiator. He also said the boiler is shutting off too quickly, and the pump is working fine but had been turned down too low so he turned it up to what it should be.

    His view on the matter was the system was full of crud and needed a power flush, which would take two of them a full day and cost £600-£800 plus extra for an inhibitor and possibly a magnaclean. He also recommended the system be switched from an open to a closed to stop this happening again. Presumably for more money. I didn't go too far in finding out the cost.

    Apart from the cost, I am concerned that pressure required to flush an unpressurised system plus switching to a closed pressurised system could cause leaks - most of the downstairs pipework is under tiles and I don't want to have them ripped up if something goes wrong.

    Also being female, I would hate to think his suggested course of action to be the result of £££ flashing before his eyes.

    Probably made the situation worse, but hubby and I have manually opened the heating valve to check whether that was at fault, and now we have hot radiators in all but the master bedroom upstairs (although the pipes to the radiator are finally getting hot in there after an hour) but nothing yet downstairs. While slow, we think it is making its way around the system. The lever on the valve is also slack across the whole length of travel (it wasn't before we depressed it), so presumably we've done something to that keeping it in the manual position (unless there is something manual we have to press to get it to go back?)

    Valve is a Honeywell F3-9630 and we think is 'plumbed' in.

    Thinking about it, I've never really logged how much I save doing all these little bits and pieces of money saving here and there. I'm sure there is probably a thread on MSE somewhere for that
