atmos frost hot water system hot water pump

Looking to go solar but not sure if your roof is suitable?

Every day, more Australians are making the switch to solar, with solar panels installed on over 2.6 million rooftops across the nation, and over 1 million solar hot water systems.

However, some homes might not be suitable for traditional solar hot water due to factors such as:

  • Too much shade: The likes of trees, chimneys and nearby buildings can impact the amount of energy produced by solar;
  • Slate roof: Slate is quite fragile, which isn’t suitable for solar collectors; and
  • Roof orientation: Collectors facing north provide optimum performance. The solar radiation received by solar collectors reduces as their orientation moves away from true north by approximately 10% to 15% when facing east or west. Collectors must not have an orientation south of east or west as they will not receive sufficient solar radiation.

If any of the above apply to you, then a heat pump is the perfect alternative because it doesn’t need to go on your roof. Heat pumps, like solar, produce renewable energy, but they use the surrounding air to heat water instead of the sun. In this article, we will explain how heat pumps work and explore key reasons why they could be a great option for you and your family.

Wondering if your roof is suitable for solar? Your local Solahart Dealer can conduct a safer home assessment to ensure the right system for you and your family.

How does a heat pump work?

To understand how a heat pump works, think of an air conditioner on reverse cycle. It draws energy from the surrounding air and generates hot water through heat-transfer technology, a reliable and efficient way to reduce water heating energy consumption and cut greenhouse gas emissions without the need for solar collectors.

Even in cold conditions, the air has some heat which is available. For freezing conditions, a quality heat pump should have an electric booster function that will be triggered to ensure you and your family have a continuous supply of hot water. Plus, it prevents ice from forming in the waterways of the water heater and causing damage. 

Why choose a heat pump?

Here are three reasons why a heat pump may be the perfect a solution for you:

1. Great alternative in homes where traditional solar isn’t possible

A heat pump provides reliable hot water for your family and is suitable for residential applications when you want energy-efficient hot water without the need for roof space for solar collectors.

They can usually be installed in the same location as your outdoor storage water heater, and can often be connected up to the existing plumbing and electrical connections, making it a great replacement for an existing water heater.


2. Eligible for Government Incentives

Making the move to renewable technology can sometimes be a costly investment, but the energy savings will go on for years. The good news is that a heat pump qualifies for government incentives known as Small-Scale Technology Certificates (STCs) that can be used as an up-front discount to reduce the cost of your purchase.1

3. Reduce your hot water energy usage 

Hot water typically accounts for around 25% of an Australian household’s energy use.2 As a heat pump uses the surrounding air to heat water, you can significantly reduce the amount of energy you consume to heat water, thus enjoying great energy savings.
