Integrated vs Split Heat Pump Hot Water systems – What's the difference and which is best?

A split system heat pump and an integrated heat pump both provide efficient heating and cooling, but they differ in design, installation, and application. Split system heat pumps use separate indoor and outdoor units, making them a flexible option for retrofits and homes with limited space. Integrated heat pumps combine multiple components into a single system, often delivering whole-home heating, cooling, and hot water in one solution. This article explores the key differences, benefits, costs, energy efficiency, and ideal use cases of each system to help homeowners choose the best option for their comfort needs and budget.
