The U.S. Department of Energy released a supplemental notice of proposed rulemaking (SNOPR) pertaining to residential furnaces in September.

Several manufacturers are looking to challenge the ubiquitous furnace by offering a different option: the hydro-air system, which they claim is a cleaner, more efficient, and more comfortable alternative to conventional furnaces.

Condensing furnaces offer many consumers the benefit of higher efficiency and thus lower energy bills, but for many homeowners, comfort is the primary reason they choose to purchase such equipment.

In this troubleshooting situation, the equipment that needs servicing is a condensing gas furnace in a relatively small home of approximately 1,200 square feet. The capacity of the unit is 40,000 Btu and it is equipped with an LED readout system.

This heating showcase provides in-depth information on the features of each individual unit and also includes technical support information from the manufacturer. The manufacturers provided all of the data included in the product grid as well as in the photo feature; therefore, any questions should be directed to them via the contact information provided in the photo feature section.

This pellet stove offers polished ceramic finishes, solid cast-iron components, and quiet operation. The unit is strong enough to evenly heat an entire home via its smart-zone heating technology. 

This unit is a shorter version of the M7RL gas furnace, as it does not include an integrated coil cabinet. To install this model, HVAC contractors will add a separate coil box, also manufactured by Nortek Global HVAC, that can accept evaporator coils up to 25 inches tall.
