Residential Gas Tankless Water Heaters

Looking for an energy-saving alternative to a traditional hot water tank for your home?  Look no further than Onsen Gas Tankless Water Heaters, the industry’s most affordable and reliable on demand hot water heaters!

The ideal solution for all your home hot water needs, Onsen Gas Tankless Water Heaters are designed to supply hot water for up to two standard bathrooms in a single family home. Powered by either natural gas or liquid propane, they offer up to 82% efficiency.

The Onsen Gas Tankless Water Heaters are energy efficient because they only heat water when you need it. Just turn on the tap and the unit heats the water instantly. No need to wait for your water to heat up before taking a shower or washing the dishes. Because water is heated instantly instead of being stored in a hot water tank that is constantly using energy to keep the water hot, the Onsen Gas Tankless Water Heaters are incredibly energy efficient, saving you 20 to 40% on your utility bill.

The Onsen Gas Tankless Water Heaters feature a built-in anti-freeze circuit to protect your water heater against unexpected subzero temperatures.

With their small and durable design,  Onsen Gas Tankless Water Heaters take up very little space and are easy to install. The installation manual contains easy to follow instructions and the units work on standard ¾” gas inlets. We highly recommend hiring a certified gas plumber for installing any residential gas tankless water heaters to make sure the installation is up to code.

Onsen Gas Tankless Water Heaters can supply multiple fixtures at the same time, providing enough hot water for one person to take a hot shower while another washes the dishes.  Because the water is heated on demand, you’ll never run out (unlike a hot water tank!).
