Turn on your hot water faucet and water is heated instantly as it flows through the heating coils. Paloma's burners shut off automatically as soon as you turn off the faucet. The Paloma modulating control automatically adjusts the flame to the water flow you select. Paloma tankless water heaters produce hot water only when and as much as you need. That's why you can save energy and money.

Wall-mounted Paloma tankless water heaters are built to perform efficiently with very little maintenance. First class materials include a copper heat exchanger and combustion chamber, brass controls, stainless steel burners, and a hard baked porcelain exterior. Palomas are easy to service and all parts are easy to replace.

Save dramatically on your current water heating bill. Storage-type hot water heaters lose heat all day long (and all night too!). They consume more energy than any other job in the home except space heating. Paloma tankless gas water heaters heat only the water you need as you're using it. You never store hot water again. You never wait for water to heat up again. You never run out of hot water!
