Forge & Flame P42I-TC Pellet Insert - 24" - Matte Black, Powered by Harman Technology
The 24 inch Harman P42i-TC is for fireplaces with a bit more height to work with, and it uses that room for a bigger hopper. At 64.5 lb of pellets, it goes longer between fills, which is the kind of thing you appreciate on a January morning.
Up front, a Matte Black cast iron face and flame-reactive mirrored glass give it a classic look. EASY Touch Control with a built-in programmable thermostat and a wireless room sensor keeps the temperature where you set it, and a 134 cfm distribution blower sends the warm air out into the room. The insert rides on a track system, and Harman rates it at 79% efficiency (HHV).
What Makes the P42i-TC (24 in) Different
- A 64.5 lb hopper. The 24 inch version holds 64.5 lb of pellets, so you're filling it less often.
- A cast iron face. The cast iron face gives the P42i-TC a traditional, substantial look in front of an existing fireplace.
- EASY Touch with a programmable thermostat. Set a schedule on the built-in programmable thermostat, and the wireless room sensor and ESP control hold the room within one degree, according to Harman.
- Insert track system. The insert sits on a track system, so it's easier to slide out when service time comes.
- Illuminated hopper lid. The glass hopper lid lights up, so you can check the pellet level without opening anything.
