Well. Condensing boilers and electric showers, eh? Is that what's going on over there? (sniffs.) Looks like the Brits have got a darned good idea! Instead of keeping 50 gallons of water hot all the time, in case anybody should need any, they heat it up shortly before using it! Brilliant! No, we don't ave anything like that over here, that I know of.
Actually, we do. It's the newest thing in water heaters. The "tankless water heater". We have a plumbing company and my husband just attended a class on installing them. He's considering installing one in our home when the current 75 gallon gas heater goes kaput. I'm not convinced yet. They are expensive. However, they are supposed to last between 15-25 years so it's not as horrible as it sounds when you hear the price. Unless you have a circulating hot water system installed, you wait for a couple of minutes for the hot water when you turn on the tap. It's wasteful and must be irritating as hell. Anyway, we have them, just call them by a different name. Sorry your heater's gone kaput on you Ballistic. Still am not sure what an electric shower is. Possibly an electric water heater only for the shower instead of the full house water heaters we have here.
