High-efficiency water heater
The Ilios high-efficiency water heater (HEWH-500-AS) runs on a natural-gas engine. It extracts energy from the atmosphere, pumping it to a useful temperature using a standard vapor-compression refrigeration cycle. Free waste heat from the engine is recovered, adding to the unit’s capacity and efficiency. The Ilios HEWH output is nominal 500,000 Btuh and suitable for facilities with a gas demand of 2,000 therms or more per month. —Ilios Dynamics

Pressurized deaerator
Counterflow-tray deaerators from Industrial Steam remove dissolved oxygen in excess of 0.005 cc per liter from 5 percent to 100 percent of deaerator capacity. Electronic instrumentation for modulating deaerator level control includes a HART-compatible differential-pressure transmitter, proportional–integral–derivative controller, and motorized control valve. —Industrial Steam

Light-commercial boilers and water heaters
