Radiators not heating but water being heated. A heating engineer said motorised valve was ' burnt out' and needed replacing. Meantime he bypassed the valve to restore heating. Is that safe and effective. He said replacement valve cost would be c€200. Please advise
 
Not much you can do if a motorised valve fails, they aren't necessarily cheap and there's time and labour. Those valves have a manual override (in case the motor fails) but you want to get this fixed properly as it isn't efficient.
I had one of them failing on me after 26 months, the other is now 7 years old and still working (the replacement 5 years and no problem).
If you are still in warranty you might at least get a new valve for free, but probably still have to pay for the labour.

Edit: if you get the same make/model valve it is potentially quicker and easier to replace as it would just be a motor switch, otherwise you'd potentially empty and refill the system.
 
Thanks do you know how safe is it to bypass the valve could the boiler overheat or blow up or cause carbon monoxide poisoning
 
its safe, but not as efficient. You will probably find that your hot water is hotter than usual as it wont have a way to stop heating once it reaches its ideal temperature.
