Heat Pump Cost Comparison

View a sample chart from a heat pump economic estimator showing potential annual savings for water heating with an ammonia heat pump.

A heat pump economic estimator shows potential annual savings for water heating with an ammonia heat pump.

In this example, the potential savings for water heating using an ammonia heat pump are shown. Among the criteria compared are utility cost input, water-related information, heat source, plant operation data and overall cost comparisons.

For example, consider a processing facility that needs to heat 96,000 gal/day, or about 100 gal/min, of 65°F (18°C) water to 135°F (57°C). The total amount of water heated per year is 24.9 million gallons. For a full comparison, see the full article using the link at the bottom of the page.

Avoiding scale, corrosion and microbiological growth — all of which diminish effective heat transfer — is the focus of any water treatment approach for water-contacted process heating and cooling equipment.
