How efficient is a Hot Water Heat Pump?

The efficiency of a heat pump is known as the Coefficient of Performance or COP. This is a ratio of the heat delivered to power consumed. For every 1kW of electrical input energy, the Black Diamond AquaCore Hot Water Heat Pump absorbs freely available heat energy from the outdoor air to provide the home with approximately 3.6kW of heat output.

Compared to typical gas and direct electric heating systems that can have higher running costs with inefficient COPS as low as 0.82*, Black Diamond AquaCore Hot Water heat Pump provides a real energy efficient alternative.

How does it work and what are the key components?

A Black Diamond AquaCore Hot Water Heat Pump is made up of 3 key components that seamlessly work together to provide super energy efficient water heating – the outdoor unit, indoor Heat Exchanger and an existing or new cylinder.

The Outdoor Unit

The Black Diamond AquaCore Hot Water Heat Pump System incorporates an outdoor unit just like any heat pump space heating system. It uses electricity to absorb freely available warmth from the surrounding air and then transfers it to your home so it can provide energy efficient hot water heating all year round.

The system utilises environmentally conscious R32 refrigerant in the outdoor unit which has 1/3 the Global Warming Potential (GWP) of R410A commonly used in other systems, meaning it is better for the environment.

The Indoor Unit

The AquaCore ensures water is heated to 62°C and is fed directly into the top of the cylinder. This means that this water is ready to use straight away. In a traditional electric system it can take hours to heat the water cylinder enough to produce 60°C water from a cold tank situation.

Furthermore, the system features fast recovery of a full water tank and can reheat an entire 180L cylinder in 2 ½ hours where traditional electric cylinders can take up to 3 ¼ hours in winter*.

The Hot Water Cylinder

The Black Diamond AquaCore Hot Water Heat Pump System is designed to easily integrate with existing or new hot water cylinders so you can benefit from capital cost savings on retrofits.

Smart Hot Water with Wi-Fi Control to Maximise Energy Savings

Why pay to heat your water 24/7 when you can maximise energy efficiencies by only heating up the water tank when you actually need it. With Wi-Fi Control you can now monitor your tank temperature and start a reheat cycle when you know you're actually there to use it. Now you will never run out of hot water even when unexpected guests turn up!

In addition to setting the exact water temperature, you can also set up a reoccurring schedule to have your hot water ready to use when you get back home from work every night.

Furthermore, Wi-Fi Control also makes it easier for you to tap into off-peak power rates or free power hours offered by many electricity companies - maximising energy efficiencies.

AquaCore comes ready with Wi-Fi Control, just connect the AquaCore indoor unit to your router with an Ethernet cable and download the app – saving money on heating your water has never been this simple!

* Ensure that your AquaCore unit has a wired Ethernet connection to your home’s wireless router. This should be discussed with your installer and setup at the time of installation.
