When it comes to choosing the best hot water system for your home, there are a few different options to consider. Heat pump hot water systems are becoming increasingly popular among Australian homeowners due their energy efficiency, lower running costs and minimal environmental impact. But what exactly is a heat pump hot water system and what types are available? Let’s take a look.
A heat pump hot water system uses the same technology as a reverse cycle air conditioner to transfer heat from one place to another. It works by pumping refrigerant through an evaporator coil, where the refrigerant absorbs heat from the environment and carries it to a compressor. The compressor then compresses the refrigerant and forces it through a condenser coil, where it releases its heat into the hot water cylinder. This process is repeated until the desired temperature of your hot water is achieved.
There are three main types of heat pump hot water systems available: air source, ground source and exhaust air systems.
Air source systems use outside air as their energy source, making them ideal for cooler climates as they can operate in temperatures down to -7°C. Ground source systems use energy from underground pipes filled with glycol solution and are suitable for both residential and commercial applications in all climates. Exhaust air systems utilise warm air from your home or office and can be used in combination with other heat pump models for enhanced efficiency when needed.
No matter which type of system you choose, you’ll enjoy low running costs due to their higher efficiency than traditional electric or gas hot water systems. Plus, they come with inbuilt safety features too so you can rest assured that you’re getting a safe and reliable system that will last you for many years to come!
