High Efficiency Gas-Fired Modulating Condensing Boiler

High Efficiency Gas-Fired
Modulating Condensing Boiler
Convertible (Floor or Wall)
Residential Gas Modulating Condensing Hot Water Boiler
Winter is notorious for all sorts of life’s little gems. With the ever present threat of colds and flu, school closings
and delays, and an unpredictable daily commute - a runaway heating bill is the last thing you need. The truth is,
most homeowners focus solely on utility costs and don’t actually think about their heating system until it needs
to be repaired or replaced. One “No Heat” call to your local contractor can cost $300 or more, just to diagnose
a problem and if your boiler has out-lived its warranty, you’ll be responsible for the full cost of parts and labor.
Your old low efficiency heating system can have an annual fuel utilization efficiency (AFUE) of
70%. That means 70% of the energy in the fuel becomes heat for the home and the other
30% escapes up the chimney and elsewhere. With an old inefficient boiler you could be
throwing away up to 30% of the money you spend on fuel each year.
Doesn’t your family deserve a new high efficiency home heating
system and all the comfort and peace of mind that come with it?
The 97gb features 95% AFUE.
Just add up the savings:
- 95% AFUE
- Sealed Combustion
-*Built-in Outdoor Temperature Reset
(*A factory standard Outdoor Temperature Reset adjusts water supply temperature for best possible fuel economy based on actual seasonal conditions.)
The increased efficiency of the 97gb could save you over 40% on your heating bill each year.
If you pay $1,800 annually to heat your home, you could save as much as $720 per year.
That’s $3,600 over 5 years!
If you have kids or pets that play in the basement or utility room, the 97gb offers optional wall
mount installation, freeing up valuable floor space and easing ground level safety concerns.
Since most of us have better things to do than fumble with the thermostat, the 97gb has
an advanced microprocessor control that continuously monitors supply and return water
temperature, automatically adjusting the boiler’s output to keep the whole family comfortable.
Another plus, when used with an indirect hot water heater, the 97gb quickly and efficiently
redirects heat when and where it’s needed. No standing around, waiting for hot water.
