Need of Comfortable Home Heating?
A cup of hot cocoa, the warmth of a crackling fire,

winter.

every home.
For

 Everyone
wants to have control over their energy bills. And,
with the Lennox Conservator 90 Series boiler, you

This means that 90 cents of every dollar used to
heat your home is being put to good use.
The
heart of the Conservator 90 high-efficiency water
boiler is its cast aluminum heat exchanger, which
transfers heat three times faster than conventional
cast iron. This ultra-efficient material means you'll
feel comfortable warmth quicker. It also makes the
boiler ideal for use with radiant systems.
This
lightweight boiler's compact size allows for simpler
installations in a basement, closet or an alcove
enclosure, and it can be fueled by either natural*
or LP gas in order to meet your specific needs.
The
Conservator 90 water boiler can protect your family
not only from the harsh temperatures of winter but
the shock of outrageous energy bills as well, giving
you...One Less Thing To Worry About.®
