D+R LEARN’s Best Practices for Residential Heat Pump Water Heater Installation

A heat pump water heater works by extracting heat from the surrounding air and transferring it to water stored in a tank. It consists of essential components such as the compressor, evaporator, condenser, and expansion valve—all of which work together to provide efficient heating. With COP values ranging between 2 to 4, HPWHs generate two to four times more heat energy than the electricity they consume, making them a smart choice for reducing energy costs and environmental impact.
The efficiency of a HPWH depends greatly on proper system sizing, design considerations,and installation techniques. That’s why this course was created—to provide a step-by-step guide covering everything from initial setup to post-installation procedures. Whether you’re an installer, builder, or homeowner, learning best practices ensures the system operates at peak efficiency while guaranteeing user satisfaction.
