We have also installed many high efficiency gas fired boilers and hot air furnaces. These include and are not limited to:
Weil-McClain gas fired hot water boilers, steam boilers, and hot air furnaces
Buderus gas fired hot water boilers and steam boilers
Peerless gas fired hot water boilers and steam boilers
Goodman gas fired hot air furnaces
All of these products are rated at an efficiency of 90% or higher reaching up to 98 % efficiency. Because of this efficiency the units condensate and creates water that is used to cool the gas emmisions as it exits the system. This is what makes the units so efficient and helps conserve energy.
With these products being so efficient you will save money on your gas or propane bill but also conserving energy. These products are also enery star rated because of the energy they conserve.
