Heat pumps: Split vs. Linked systems?

So you’ve decided to get a heat pump for your landed home. The question now is… should you get a split or linked (integrated) system? We’ve listed down all the pros and cons of both types of heat pumps here:

Summary of the differences between the split and linked heat pump systems.

Initial Cost

Split heat pump systems are the oldest versions of heat pumps available. This also makes it the most affordable heater system. A 300-litre heat pump system will cost around $5500.

An integrated or linked heat pump system is equipped with advanced technologies to make them more streamlined. This however makes the linked heat pump systems more expensive, costing around $7500.

Ease of Installation

For split heat pumps systems, it is easier to install because the tank and compressor is split. This makes it easier to carry up to your house as the weight is separate. This system is also recommended due to it's flexibility, especially if you have less space available in your home.

For linked systems, both the tank and compressor are combined. This means both the tank and compressor are found in one neat system. However, this also makes the linked heater heavier to carry.
And if you want to install the heat pump heater on your roof, you may need to use a crane which may cost an additional $1800+.

In the end, the system that's best for you also depends on the layout and space available in your house.

Efficiency and Performance

Because the split heat pump and linked heat pump look very different, and people often think one is better than the other. But, technology has changed.

Now, the performance and efficiency of both heaters is the same. You will get the same output of hot water from both heaters.

Maintenance

Maintenance is recommended for all heaters to make them last longer. Both split and linked heaters need regular maintenance every 3 years.

The cost for maintaining a split system or linked system is the same, and only depends on the size of your tank.

Warranty

All AOS tanks and heating elements are coated with the patented Blue Diamond™ technology. This Blue Diamond™ coating reduces scale from forming on the tanks and elements. This makes the tanks more durable and last longer than the average 5-year heater lifespan.

This also applies to the split and linked heat pump tanks.

Conclusion

When comparing the performance and efficiency of both the split and linked heat pump system, the difference is minimal. They are both energy efficient units with a durable and long-lasting tank.

The main factor of deciding whether a split or linked system is better for you is the price, and available space in your home.
