I’ve interviewed a dozen or so people who have installed tankless water heaters (which heat your water on demand rather than storing hot water in a tank) — and several contractors who have installed dozens more tankless water heaters — and the comments I’ve heard about the devices have been overwhelmingly positive.
Here are some positive comments:
Never run out of hot water, good for the environment, saves energy, takes up next to no space, earthquake safe, good for cottages, good for one-person households, good for spatially challenged areas.
And here are some negative comments:
Don’t meet high water demands of North Americans, needs maintenance plan factored in, installation difficult, you won’t notice any savings right away, plumbers are unfamiliar with them, sensitive to water pressure, turn on too much cold water (like flushing toilet or using clothes washer) and the heater shuts off.
What do you think? Do you have a tankless water heater? Any suggestions for those of us considering one?
