I've had a new boiler installed today, but was out when the installer left. He's left me the instruction manual. If it were in Klingon it would make as much sense. My old boiler, you just pushed a few buttons to set the times for on-off, turned a dial for temperature, and it worked. This one, I have NO idea where to start. I don't even understand half the features it offers. I'm sure it'll be super efficient and economic, if only I can get it to work. I'm glad it's mild at the moment! Does technology really have to be so complicated?
