As Australian homeowners, we all like to save money and energy when it comes to heating our homes. One way to do this is by installing an air source heat pump water heater. Heat pump water heaters are a great way to reduce energy consumption while also providing hot water on demand. But what are the different types of expansion devices used in air source heat pump water heaters?
The most common type of expansion device used in an air source heat pump water heater is an expansion tank. An expansion tank is a sealed container installed in the system which allows for the extra volume created when the heated water expands due to increased temperature. It also helps to prevent backflow and keeps pressure consistent in the system. Another type of expansion device used in an air source heat pump water heater is a pressure relief valve. This valve is designed to release excess pressure from the system if it gets too high, preventing damage from occurring due to over-pressurisation.
A third type of expansion device used in an air source heat pump water heater is a thermal expansion control valve (TECV). A TECV works by allowing hot water into the system as it expands due to increased temperature, while simultaneously allowing cooler water out as it contracts due to decreased temperature. This helps keep pressure consistent and also prevents backflow. Finally, some systems may also use a pressure regulator or flow control valve, which helps regulate the flow of hot water into the system and ensures that it remains at a consistent pressure level.
Overall, these are just some of the different types of expansion devices used in air source heat pump water heaters. It’s important that you understand how each type works so that you can ensure your system is running efficiently and safely. If you’re ever unsure about any aspect of your heater’s performance or safety, be sure to call in a qualified technician for advice and assistance.
