Gas Heaters: New generation heater

Reviewed by:

The GF 3800 is a new generation of gas-fired space heaters. Capable of heating 1,500 square feet of living area, it has a seven-day programmable thermostat, child lock, automatic reset after power outages and a high-efficiency heat exchanger.

Efficiency is enhanced by the "pipe within a pipe" venting system. An outer pipe draws in cold air for combustion and the inner pipe exhausts heated air, which serves to preheat incoming combustion air.
