Lennox 99M83 Heat Exchanger

Heat Exchanger

Innovative Heat Exchanger Technology and highly efficient Burner Design.

The Lennox Heat Exchanger is normally installed on a Forced Air Furnace or a Boiler. It can also be retrofitted to an existing furnace. The heat exchanger transfers heat from the exhaust gases to the fresh air that's being drawn into the home. Its compact design, available in stainless steel or natural aluminum, fits easily in today's tight wall spaces and meets tough Residential efficiencies like 92% AFUE.

The Lennox® Genuine OEM Heat Exchanger is designed and manufactured to fit Lennox® heat pumps, furnaces and air handlers. This component helps to transfer heat from the air outside the home into the air circulating inside. When paired with a suitable outdoor coil and blower, this heat exchanger sends hot air throughout the space for better temperature control versus the single-piece outdoor coils currently on the market.

Efficiently delivering affordable heating comfort to your home, the Lennox Heat Exchanger is the most efficient way to deliver heat to your home. No matter if you choose a forced-air furnace or an air conditioner, the unit is designed for durability and high efficiency.

Increase the efficiency of your home heating system by upgrading to a heat exchanger. Heat exchangers are made of a durable aluminum alloy and have larger tubes and fins than regular air conditioner coils, increasing airflow and delivering more heat. Simply remove old parts and replace them with this new Lennox heat exchanger, available at Lowe's. Check your owner's manual for specific parts needed.

The Lennox Hearth Card® is designed to be used on natural gas or propane furnaces as part of a radiant heating system. This advanced heat exchanger takes energy from your furnace’s combustion process and uses it to preheat your radiant flooring before delivering the heated air directly to your home.

Tubing and fins set in a gas or watertight case used in the exchange of heat between two fluids of different temperature. This heat exchanger is designed to transfer hot water from an air-conditioner into a cooling tower during the summer and, conversely, to transfer chilled water from a cooling tower into the air-conditioner in the winter.
