What's the Big Deal About Tankless Water Heaters
As energy supplies tighten and fuel costs increase, tankless water heaters are gaining attention in some quarters because they do not require the storage of hot water. Tankless water heaters are certainly appropriate in some situations, particularly in point of use applications, but all factors should be carefully weighed before replacing a storage (tank-type) water heater with a tankless (instantaneous) water heater as the central hot water supply for a residential application. Tankless water heaters have advantages. They are compact and are easy to drain; consequently, they could be ideal for applications where space is a premium or in small vacation homes.
