The Mighty Therm2 pool heater is designed for the replacement market. It is available in seven sizes from 500 to 2000 MBH. The heater features a built-in automatic mixing system that allows it to handle return-water temperatures as low as 60°F without internal condensation. The Mighty Therm2 achieves 87 percent thermal efficiency and ultralow (10 ppm) NOx emissions. It is available in natural-gas or LP models, with gas and water supply on the right or left side and flexible Cat I or III venting. —Laars
Expanded rooftop line
The WeatherExpert Series of commercial rooftop units has been expanded and now includes models with capacities ranging from 6 to 23 tons. The line features integrated-energy-efficiency-ratio ratings of up to 21.0. The 6- to 23-ton units are available with three stages of capacity control utilizing scroll compressors and electronically commutated outdoor-fan motors. Additionally, the indoor-fan motor is controlled by Carrier’s staged-air-volume system, which precisely matches fan operation to the staging compressors. These units are available in gas/electric, electric/electric, and cooling only models. —Carrier
