Overview of the Conservator
The Lennox Conservator boiler is a gas-fired induced draft water boiler. Six sizes, all with product numbers beginning with GWB8, are available in a range of efficiency ratings from 82.0 to 84.4 percent AFUE. This boiler is designed with flexibility in mind, as it can be configured to accommodate several installation needs, including side wall venting. It also can function with either natural or LP gas.
The Conservator has an electronic ignition to minimize gas consumption. The induced draft combustion allows for efficient heat transfer as the inducer fan optimizes the flue gas rate of travel through the boiler. The unitís efficiency is further aided by the thick fiberglass insulation within its jacket; this insulation is designed to reduce fuel consumption and minimize heat loss during the off-cycle.
This line of Lennox boilers is manufactured with a baked-on enamel finish, cast-iron heat exchangers and corrosion-resistant titanium burners. Additionally, it comes with safety features such as a pressure switch that ensures clear flue for venting. Factory testing is performed for each unit for quality assurance for consumers.

"Lennox #2 Oil Home Furnace"
If you have #2 home heating oil, this oil burner does the job. We have forced hot water and the house heats up fast. Always plenty of hot water for showers, dishes, etc. Runs pretty clean, we've had it for 11 years and no problems to report with it. We recently had our chimney swept and the sweeper was surprised that it hadn't been longer, the chimney was really clean.

"Stay away from Lennox"
Started with Lennox Complete Heat in 1996. Two years later totally replaced with new Complete Heat because of so many problems with first unit. Four years later another completely new unit after prior unit failed. This unit then failed in 2004 and we "upgraded" to a GWB9 which lasted less than 5 years before the heat exchanger developed a leak. This heat exchanger lasted less than 2 years before it also developed a leak. Just paid over $2,000 for replacement of the heat exchanger and many parts. Now unit is backfiring (scary) and short cycling. Local company rep ignores my emails and calls asking which service company can actually fix his product. Cannot reach humans at company Customer Relations number. Terrible products from terrible company.
Other Conservator Reviews
Other online discussion boards include multiple instances in which this unitís electronic igniters fail to light. In most instances, these Conservator boilers are about 10-years old. In the instance of one homeowner on handymanwire.com, the igniters were replaced but the problem continues. After this additional failure, a contractor on this forum recommends that the sensors be replaced; according to this expert, they can ďbecome fouledĒ in only a few months time. Other online threads describe problems with the fan/limit control sticking, which can result in the blower running for too long. This issue can reportedly be fixed by adjusting the unitís calibration.
