GWB9-IH Boiler
High-efficiency, gas-fired water boiler
The innovative GWB9-IH boiler achieves the highest levels of efficiency with an AFUE rating of 90%. At the heart of the GWB9-IH is a cast-aluminum heat exchanger, which transfers heat three times faster than conventional cast-iron.
Here are some of the top features of the GWB9-IH:
- Efficiency rating of up to 90% AFUE.
- ENERGY STAR® qualified which means it meets or exceeds U.S. federal guidelines for energy efficiency.
- Cast-aluminum heat exchanger transfers heat up to three times faster than traditional cast-iron exchangers.
- Easy integration with traditional radiator systems to provide precise heating comfort, regardless of outdoor temperatures.
If you have any questions on the GWB9-IH or any of the other hot or warm water or steam boilers listed below, or would like to schedule an in-home consultation or a repair on an existing system, feel free to contact us anytime at (734) 424-9170.

Patching a broken or old system means putting today's money into yesterday's technology. With a new boiler, you get a fresh start with advanced high-quality technology designed for comfort and reliability.
However, simply installing a new boiler into an old system may not be the best solution. Haley can evaluate your entire system to ensure you're getting the equipment that fulfills your comfort needs.
Be sure to let us know if you've experienced hot or cold spots in your home or hot water shortages when washing, cooking, etc. Lifestyle changes could also lead you to consider these various heating options:
- Water-heating upgrades: With a new boiler, you should also consider two different domestic water heating options. An "internal tankless coil" can be immersed into the boiler's hot water. The coil picks up the heat and transfers it to fresh water contained safely inside the copper piping. An "indirect water heater" is a separate external storage tank. Hot water is piped out of the boiler's heat exchanger into a sealed coil inside the tank. Heavily insulated to minimize heat loss, these indirect water heater units can hold up to 119 gallons.
- Zoning upgrades: Hot water systems can be "zoned"--which means different areas of the home can be regulated by their own thermostat. For example, one zone can be created for the sleeping area, another for the living area, and still another for the kitchen/dining area. If temperatures fall off more quickly in one zone than another, the thermostat will call for hot water to be circulated to that particular zone. Thermostats with a "set-back" capability let you turn the temperature down in unoccupied areas--such as bedrooms during the day--to save fuel.
- System enhancements: Along with a new boiler, there are inexpensive upgrades that can improve home comfort. A constant circulation pump and a few carefully placed non-electric radiant valves can enhance the performance of existing radiation. "Tempering" valves in combination with in-floor tubing creates comfortable radiant floors.
