Heat pumps: Split vs. Linked systems?
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:
How Much does it Cost?
Split heat pump systems are the first versions of heat pumps available. This are an affordable, modular heater system. A 300-litre heat pump system will cost around $5500.
An integrated or linked heat pump system has with advanced technologies that make them more streamlined. For their sleeker design, linked heat pump systems are expensive, costing around $7500.
How Easy to Install?
Split heat pumps are easier to install because the tank and compressor are separate. This makes it easier to carry up to your house as the weight is split. It is flexible, but you need to have more space to fit both a compressor and a tank.
In linked systems, the tank and compressor are combined in one neat unit. However, this also makes the linked heater taller and heavier to carry. It may not fit into a normal lift, so if you want to install the heat pump heater on your roof, you may end up using a crane which may cost an additional $1800+.
In the end, the system that's best for you depends on the layout and space available in your house.
How Efficient are the Two Systems?
Because the split heat pump and linked heat pump look very different, people often think one is better than the other. But with improved technology, the efficiency and performance of both heaters is the same.
Both heaters are equally efficient, giving you 80% savings. Water pressure is great, and they can support both rain showers and bathtubs.
What Maintenance and Warranty do I Get?
Both split and linked heaters need regular maintenance every 3 years, costing about $150/year. And because AOS tanks have Blue Diamond™ coating, the tanks have a longer lifespan of up to 10 years.
Blue Diamond has heavy duty scale resistance because it is glass, and while it is easy for scales for form on metal, it is hard for scales to form on glass.
When scales form on your tank or heating element, it takes longer for your tank to heat up hot water. This makes your heater work even harder to give you and wears down its efficiency.
With the Blue Diamond coating, it allows efficiency of AOS heaters to stay high, making the tanks last longer than the average 5-year lifespan. When our tanks last this long, we have confidence to give you a 3-year full warranty compared to the industry standard of 1 year.
Conclusion
When comparing the split and linked heat pump systems, the difference is small. 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.
