Timer used to control when the hot water tank is heated.

New direct vent propane fireplace. Antique brick reused from wall replacement at owner’s previous home.

The HRV (Heat Recovery Ventilator).

This unit provides fresh air to the home. It recovers heat from the exhausted air to heat the incoming fresh air.

The house is now tight enough to require one of these units to provide fresh air.
