Our take on the Camplux Climatech 3 Indoor Gas Tankless Water Heater 102,000 BTU

The Camplux Climatech 3 is an indoor gas tankless water heater rated at 102,000 BTU, delivering up to 4.22 GPM of on-demand hot water for two to three fixtures. It holds temperature within about 1°F using sensors and a control chip, and its anti-freeze cycle kicks in below 39°F to protect the unit. It suits tiny houses, mobile homes and apartments where a tank won't fit, and it saves over half the space of a tank heater. Against rivals, it offers precise temperature control and freeze protection at a high BTU rating, but it needs a 3-inch stainless vent and a gas supply, so installation is more involved than a plug-in electric unit. Owners rate it highly, though the sample of ratings is small.

About the Camplux Climatech 3 Indoor Gas Tankless Water Heater 102,000 BTU

The Camplux Climatech 3 is an indoor gas tankless water heater rated at 102,000 BTU. It delivers 4.22 GPM of hot water on demand, enough for 2 to 3 water points. It suits tiny houses, mobile homes and apartments.

It holds temperature within ±1°F using advanced sensors and a smart chip. An oxygen-free copper heat exchanger gives 96.9% efficiency and delivers hot water in 3 seconds. Anti-freeze protection activates below 39°F, using 4 heat modules with 100W power. The unit is built for a 5-year lifespan.

The compact design saves over 50% of the space a tank water heater takes up. It has 1/2" NPT connections for both gas and water and a UL-approved plug. It pairs with a 3" stainless steel vent pipe. The Camplux VP70T vent pipe kit or the optional WT300 wall thimble can be used for setup. Use it only with approved propane or natural gas connections, with adequate ventilation, and follow local gas and plumbing regulations and the user manual.

Questions and answers

How many fixtures can it run at once?
Up to 4.22 GPM, enough for two to three hot-water points running together. Running more at once splits the flow and lowers temperature at each.
Does it work in cold weather?
Yes. An anti-freeze cycle with 100W heat modules activates below 39°F to protect the unit. Output still depends on how cold the incoming water is.
What venting does it need?
It pairs with 3-inch stainless steel vent pipe and is designed for indoor installation. Venting must meet local code.
What connections does it use?
Standard 1/2-inch NPT fittings for both gas and water, plus a UL-approved plug. A qualified installer should handle the gas line.
Is it a good fit for a tiny house or apartment?
Yes. It is built for tiny houses, mobile homes and apartments, and its compact body saves over half the space of a tank heater.
Does it need electricity?
Yes. It plugs into a standard outlet to power the controls and the anti-freeze cycle, in addition to the gas supply.
