UH-60 Commercial and Residential Gas Fired Forced Air Heater

The UH Series line of gas-fired, tubular exchanger, induced draft, hot air heaters are now available for use in commercial, industrial, agricultural and residential applications. This line of heaters features a low profile design with a durable, powder-coated black enamel exterior and stainless steel louvers for an exceptional aesthetic appeal, and a swept-wing impeller with finger-proof fan guards for low noise operation. Additional features include operational troubleshooting lights and and integrated mounting brackets for ease in installation. The UH Series offers an out-of-the-box separated or power-vented combustion option. The separated combustion heater is designed for heating areas that may contain flammable materials, high humidity or corrosive environments. These heaters use a power-vented exhaust and a separate air intake duct for combustion air. Modern plastic greenhouses have low infiltration rates, so it is possible during times of peak heating to use up enough oxygen in the greenhouse to cause poor combustion or have flue gases being drawn into the greenhouse through the flue pipes. Back drafts of flue gases can be a problem if a greenhouse is located in a windy area or if exhaust fans and heaters are inadvertently used at the same time. Flue gases can affect plant and human health as will be discussed later. Separated combustion units eliminate these problems. The thermal efficiency of a standard separated combustion heater is 82 percent with a seasonal efficiency of 80 percent.
