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

D+R LEARN has had the pleasure of documenting dozens of installations over the years for training and educational purposes. Many of those installations were focused on new designs and technology centered around water heating. While heat pumps have proven over the years to be beneficial for efficiency and savings, sometimes seeing an installation in action can be the final bit of reassurance that installers and homeowners need to make the switch from traditional water heaters.

How a Heat Pump Water Heater Can Be Better

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.

Why Installation is Important

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.
