A system and method for heating water are provided. The system includes a first subcooler for receiving a first water flow, a second subcooler for receiving a second water flow, a first condenser in fluid communication with the first subcooler and the second subcooler for receiving water from both subcoolers, and a second condenser in fluid communication with the first condenser. The method involves receiving a flow of water, and transferring heat to the water using the system.
A hot water system and method are provided. The system includes a tank configured to receive hot water, a heat recovery system for heating water, and a controller configured to use the heat recovery system to maintain the hot water in the tank at a temperature within a predetermined range of temperatures. The method involves receiving a flow of water and heating the water using the hot water system.
A controller can be connected to a heat transfer system including pressure and temperature sensors, an electrically controlled valve, and a compressor. The controller can be configured to control the heat transfer system according to compressor suction superheat, compressor discharge superheat, compressor suction pressure, compressor discharge pressure, and temperature of water received at a condenser to be heated by waste-heat bearing fluid in an evaporator. The controller can include a touchscreen configured to display a user control interface configured to display views based on a permissions database defining different types of users. The views can include different views having different input fields, output fields, and output graphs. The permissions database can permit input of control loop parameters by one of the different types of users and prevent input of control loop parameters by another of the different types of users.
