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.
