Lennox Conservator Series

Lennox Conservator Series

If you want to be warm and comfortable without outrageous heating bills, the Conservator Series gas-fired induced draft water boiler offers superior performance and lower monthly costs.

Economical Energy Efficiency
The Conservator's electronic ignition reduces gas consumption, since fuel is burned only when heat is required. Thick Fiberglass insulation reduces off-cycle heat loss and saves on fuel costs. An inducer fan optimizes flue gas velocity through the boiler for greater heat transfer and higher efficiency.

Quality Construction, Built to Last
The cast iron heat exchanger and sealed ball bearing fan provide greater reliability and quieter operation. Titanium burners provide greater resistance to corrosion and oxidation than competitive stainless or aluminized steel burners.

We Build to the Highest Standards. We Stand Behind Our Warranties.
The Conservator is backed by a 20-year limited warranty on the heat exchanger with non-prorated coverage, and a 1-year limited covered parts warranty.
