Bruce –
The device is great – silent, temperature controlled = minimal adjustment, 100% efficient use of the fuel = no warm flue gas exiting the device.
In winter, the indoor air is DRY leading to static electricity and very painful cracking skin on my fingers. The heater burns gas (natural gas or propane) which releases water into the air increasing humidity. This greatly helps prevent cracking skin.
