Lennox GWB8-IE Gas-Fired Water Boiler

If you are looking for a dependable heating system and you have already considered central air and heat pumps, do not be in a hurry to get one just yet. You might want to look at having a water boiler installed in your home.

This type of heating system circulates hot water, or steam, through your home’s heat distribution system. The hot water or steam is delivered through a series of pipes and into a radiator to generate heat.

Bratcher Heating and Air Conditioning is a leading HVAC company in Normal, IL that offers energy efficient water boilers that are a great alternative to traditional ducted HVAC systems.

This article highlights the Lennox GWB8-IE Gas-Fired Water Boiler, a reliable way to stay warm and save energy.

Benefits of Boilers

Greater Efficiency

Boilers can generate heat without the need of passing through any ducts, enabling your system to have virtually no heat loss. This translates to lower energy bills due to a reduction in your heating system’s overall fuel consumption.

Quiet Operation

These heating systems operate quietly, giving you peace of mind.

Better Indoor Air Quality

Since boilers do not utilize ducts, they do not distribute dirt, dust, pollen, and even allergens. This is something you need to consider if you have people in your home that are suffering from allergies since they need to breathe clean air to avoid their allergies from being triggered.


Most boilers are smaller than other types of home heating systems. Combination boilers can be installed mounted on a wall and do not even have to take up any floor space. However, even floor-standing models are often slimmer and the water pipes take up much less space than air ducts.

Features of the Lennox GWB8-IE Gas-Fired Water Boiler

The GWB8-IE offers an efficiency of up to 84.4% AFUE, meaning it can deliver significant energy savings compared to an older boiler. So even if winter brings its worst, you’ll stay comfortable without worrying about energy use.

The GWB8-IE includes extra attention to durability, with features like a cast-iron heat exchanger and corrosion-resistant titanium burners.  Thick fiberglass insulation adds to energy efficiency while reducing on-off temperature cycling.

The GWB8-IE is available in 6 different sizes for installation nearly anywhere in your home. And if you have a traditional radiator system, the GWB8-IE will integrate perfectly to provide precise heating comfort all winter long.

Depending on where you live, different types of fuel can be more expensive than others. That’s why the GWB8-IE gives you a choice of heating with either natural or LP gas.

The GWB8-IE is made with titanium burners and a cast iron heat exchanger. Combined, these two features provide resistance against corrosion and oxidization and will keep your boiler in great working condition for years.

Here are some of the other advantages of having this model:

  • Electronic ignition control burns fuel only as necessary, reducing energy costs.
  • Cast iron heat exchanger designed for long-lasting durability.
  • Easy integration with traditional radiator systems to provide precise heating comfort, regardless of outdoor temperatures.
  • Electronic ignition control—monitors water temperature and maximizes efficiency by turning on the burner only when needed
  • Thick fiberglass insulation—minimizes off-cycle heat and energy loss
  • Vent damper—automatically closes when the boiler turns off, maintaining energy efficiency
  • 20-Year Limited Warranty on Heat Exchanger; 5-Year Limited Warranty on covered components. This product may be eligible for 10-Year Limited Warranty coverage with product registration.
