Lambro Industries 1700 Heat Economizer Kit 4 Inches

Product Description

The LAMBRO INDUSTRIES 1700 is a heat economizer kit designed to recover warm exhaust air from electric dryers and redirect it back into the living space as supplemental heat. Rather than venting heated air outside, the unit captures that thermal energy before it is lost, helping reduce the load on a home heating system during dryer operation. The kit is sized for 4-inch duct connections, the standard diameter for residential dryer exhaust. Installation is straightforward and typically handled by a qualified HVAC technician or plumber familiar with dryer venting systems.

This heat economizer is intended for residential use with electric dryers only. It fits into the dryer exhaust duct line and diverts warm, lint-filtered air back into the room rather than exhausting it outdoors. It is well suited for installations in laundry rooms, utility rooms, or basements where supplemental warmth during heating season is beneficial. This product is not rated for use with gas dryers, as combustion byproducts from gas appliances must be vented to the outside at all times.

Key Features

• Recovers heated exhaust air from electric dryers for use as supplemental room heat
• Sized for 4-inch dryer duct connections, matching standard residential dryer exhaust diameter
• White finish blends with typical laundry room installations
• Designed for electric dryer use only — not compatible with gas dryers

Compatibility

Designed for use with electric dryers connected to standard 4-inch exhaust ducting. This product is not suitable for gas dryer applications.

Installation Notes

Installation should be performed by a qualified technician familiar with dryer venting codes and local building requirements. Disconnect the dryer from its power source before working on the duct connection. Ensure all duct joints are properly sealed to prevent lint accumulation or air leakage. This kit must never be installed on a gas dryer exhaust line, as gas combustion byproducts require direct outdoor venting per applicable mechanical codes.
