HearthStone Clydesdale TruHybrid Wood Insert
The Clydesdale puts HearthStone's TruHybrid catalytic technology inside a fireplace insert, and it doesn't hide the fire to do it. A large open window lets you see as much flame as possible, which matters when you're used to an open fireplace.
HearthStone describes the Clydesdale as clean-burning and easy to operate. It's rated at 79% efficiency (HHV) with emissions of 1.16 g/hr, and its 2.4 cubic foot firebox takes logs up to 22 inches. It ships with the blower installed and a surround kit in the box, in matte black or brown enamel.
What Makes the Clydesdale Different
- A big view of the fire. The large open window keeps the fire front and center, not tucked behind a small door.
- TruHybrid catalytic combustion. HearthStone's catalytic system gives the Clydesdale a 79% HHV efficiency rating and 1.16 g/hr emissions.
- Blower and surround included. The blower comes installed and the surround kit ships with the insert.
- 22 inch logs. A 2.4 cubic foot firebox takes long splits for an insert.

Ownership & Maintenance
The TruHybrid system relies on a catalytic combustor. It should be inspected periodically and will eventually need replacement, and the installed blower needs power to run. When you buy from Hearth Doctor, you get support after the sale.
