I have had the ISAR HE for about 2 years now and although I have had to buy and fit a new PCB within the guarantee, the boiler itself has performed quite well.The downside is, I have a fault, in that it is wasting Water and Gas. I will explain. Last year to save money we had a water metre fitted, with our eye's firmly on the usage and cost's. However when we have the heating running in the cold weather It will waste unto 3 gallons of water till it reaches temperature. This is because of the very slow operation of the change over actuator. I even tried fitting a new one of these also. I am a retired installer and I do understand how these things work. If there is a mod: out there now that I could fix, please let me know. The whole point of having the boiler change in the first place was to economize. I wish I could have my Myson Midas back. Regards Alan Sutton
