Innsbrook Vent-Free Inserts

Innsbrook traditional inserts are offered with a built-in thermostat, with a Millivolt system, and with our Intermittent Pilot (IP) system. All of these inserts operate without electric power to provide heat during power outages.

The Innsbrook Traditional Millivolt and IP systems can operate with an optional remote, a wall thermostat, or even a programmable remote control thermostat
