Tankless water heater a wise investment

Energy savings, long life trump unit's higher cost

Q: I read with interest your recent column on water heaters. Mine went out recently, and I have been considering going to a tankless model. Since it would cost about three times more than a conventional heater, I was wondering what you thought about tankless heaters? Is it a smart way to go?

A: A tankless or "on-demand" water heater simultaneously provides unlimited hot water to sinks, showers and dishwashers. Any man who has endured a cold shower after his teenage daughter drained the tank doesn’t have to ask if this is a smart way to go.
