Our take on the GASLAND Gasmart C 4.22 GPM Indoor Propane Gas Tankless Water Heater

The GASLAND Gasmart C is an indoor, wall-mounted propane tankless water heater rated at 102,000 BTU and 4.22 GPM, enough for a small to mid-size single-family home. Its oxygen-free copper heat exchanger, chip-controlled modulation that holds temperature within about ±1°F, and a DC variable-frequency fan set it apart from basic tankless units. Safety coverage is broad for the class: freeze protection, overheat cutoff, thermistors, flame sensor and error-code diagnostics. It is a fit for households replacing a tank heater who want endless hot water and a compact wall footprint, but it needs a licensed install in a ventilated space and is not rated for elevations above 2,000 feet.

Questions and answers

How much hot water can it deliver at once?
It flows up to 4.22 GPM at 102,000 BTU. That covers a shower plus a sink in mild climates, but running two showers together will likely outpace it.
Does it work with natural gas?
No. It is propane-only, so you need an LP supply and the matching gas line sized by your installer.
Can I install it myself?
No. It is an indoor unit that must go in a well-ventilated area and be installed by a licensed professional following local building and plumbing codes.
Will it work at high altitude?
It is not recommended above 2,000 feet above sea level, so check your elevation before buying.
What comes in the box?
The heater, a manual, an installation kit and 1/2-inch NPT incoming and outgoing water connections.
How does it handle cold weather?
It has freeze protection and a wind-resistant DC variable-frequency fan designed to keep running in harsh weather.
