Water Heating Systems

Warm up to reduced hot water costs and increased hot water production

In many facilities, producing hot water is a major energy expense. The inability to produce adequate hot water when needed can severely impact operations. Fortunately, today's water heating technologies offer cost-effective solutions to meet the unique requirements of different facilities.

Why electric water heating?	Simplified installation and maintenance, added safety, and greater efficiency are only a few advantages.
Water heating performance measurements	Learn several ways to measure and compare the performance of water heating systems.
Water heating electrotechnologies	Quickly survey a wide range of electric water heating solutions that are available today.
Electric resistance storage water heaters	These extremely common units come in a range of storage capacities and are known for their quick recovery times.
Instantaneous electric resistance water heaters	Installed at the points where hot water is needed, these small units produce hot water on demand (with little or no hot water storage).
Point-of-use water heaters	Installed at or near the point where hot water is needed, these storage type units reduce piping costs, lower heat loss, and shorten waits for hot water.
Air-source heat pump water heaters	Remove hot, humid air from laundries or other high heat areas, cooling those areas while essentially providing free water heating energy.
Pool heating and dehumidification heat pumps	Use waste heat from heat producing equipment to heat swimming pools or spas. Some versions also provide indoor dehumidification and spot cooling.
Desuperheater and refrigeration heat reclaim units	Use waste heat from cooling unit compressors to essentially provide free water heating energy (but only when the cooling unit is operating).
Multifunction full condensing units	Use waste heat from cooling unit compressors to provide hot water heating energy, and still use for a standalone water heating if cooling is not needed.
Off-peak thermal storage water heaters	Store heat from heat producing equipment during peak activity periods to provide water heating energy at a later time.
