Smart Water & Energy offer the commercial hot water user a highly energy efficient means of generating portable instant hot water.

Our commercial Heat Pump systems have the same operating principles as an air-conditioner or domestic refrigerator. The Heat Pump gathers heat from the surrounding air, and through the refrigeration cycle, deposit the heat into water. This principle of moving heat with a Heat Pump, rather than by generating it through the use of fossil fuels (i.e. natural gas) or electric resistance, makes Heat Pump water heating the best choice for the environment.

Since Heat Pump water heating uses the same principle as an air-conditioner, it produces cool air as it makes hot water. This “free” cool air benefit can be put to use to supplement the existing air-conditioning system, or to provide “spot cooling” to hot work areas.

There are two basics types of applications for Heat Pump water heating:

• Water heating only . In these applications, hot water is made energy efficiently while the air-conditioning benefit is not used because of building configuration and other reasons. These systems are the simplest to design and control.
  
  
• Water Heating with Air-Conditioning (A/C) Benefit . Here the cool air produced by the Heat Pump water heater is used to cool an occupied space while energy efficient hot water is being made. When the A/C benefit is used it becomes important to know and/or calculate both the hot water and air-conditioning loads and the profiles of both loads throughout the day. There are two possible cases when using the A/C benefit:

a) The Hot Water Load exceeds the A/C Load.
b) The A/C Load exceeds the Hot Water Load.

Examples of applications where concurrent space cooling and water heating are required:

Restaurants Nursing Homes Laundries, Hospitals

Kitchens Food Processing Plants Photographic Processing Plants etc.
