What is a heat pump hot water system?
Traditional hot water systems use an element to heat water, which uses a lot of electricity. Heat pump hot water systems ‘pump’, concentrate and transform heat from one medium to another via a heat exchanger, then utilise it to heat water inside an insulated storage cylinder.
Heat is taken from a renewable source; either the surrounding air heated by the sun, or underground.
The process uses gas and a condenser coil to heat the water inside the cylinder. It’s much like a refrigeration cycle, but in reverse.
The evaporator fan and compressor components of the unit still use electricity during the process of heating the water. However, the amount of electricity used is significantly less and there is less energy wastage.
Why install a hot water heat pump?
With so many reasons to get a hot water heat pump installation, why wouldn’t you?
- Use less energy to heat your water
- Lower your energy bills
- Reduce your greenhouse emissions
- Save money long term (ROI)
- Make your home more energy-efficient
Being one of the highest energy-using appliances in your home, choosing to upgrade to a heat pump hot water system could slash your energy bills because significantly less energy is required to heat your water.
Energy usage is reduced by at least 50% and can be as much as 75%, depending on the brand, usage, model and climate.
Make the most of your solar
If you have solar panels already installed at your home, more of your excess solar power can be used by powering your heat pump hot water system on-site, rather than feeding it back into the grid.
Reduce your bills even more by heating your water during the day using your own free energy, rather than paying for it in the evening. Make it automated by using a timer (selected models only).
You should consider your usage patterns and the size of the tank when using timers, to ensure that your water is hot enough at the times you need to use it.
Timers can also be handy for day/night operation, as the units can produce noise when heating (similar to a refrigerator). Don’t worry, the timing settings can be overridden when needed.
If you have a solar battery, your stored solar power can keep your water nice and hot at any time, and use less energy to do so.
Save energy and save money!
Heat pump hot water systems are up to four times more energy efficient than traditional hot water systems, because they use much less electricity.
- Align water heating to your routine with programming
- Heat water during off-peak periods and pay lower tariffs
- Take advantage of the rebates available
- Cheaper power bills
By shifting a major energy-using appliance in your home to a model that uses 50%-75% less energy than its predecessor, you will quickly see savings and an excellent return on investment.
Solar system owners can use even more of their free excess power themselves, rather than feeding it back to the grid and receiving the lower feed-in tariff.
Heat pump hot water rebates
With the Solar Victoria rebate and federal government STC discount, in many cases, a heat pump hot water system installation may be yours for little to no cost. Here’s how.
Solar Victoria Solar Homes Rebate
With the Solar Victoria hot water rebate, homeowners can save up to $1,000 on the installation of a heat pump hot water system.
Here’s some more good news. If you have already received a solar panel PV rebate, you can now receive the solar hot water rebate too.
The rebate applies to installations that replace an existing hot water system that was at least three years old (from the date of purchase). More information and eligibility criteria can be found on the Solar Victoria website.
Small-scale Technology Certificates (STCs)
New heat pump hot water systems are also eligible for Small-scale Technology Certificates (STCs), a federal government funded payment to purchasers of small renewable energy systems.
With the Solar Victoria hot water rebate and the federal government STC discount, you could save up to $2,000 off the total cost of a heat pump hot water installation.
Types of hot water heat pumps
There are two types of heat pump hot water systems:
- Air-source heat pumps
- Ground-source heat pumps
Air-sourced is the most commonly used heat pump hot water system. These systems extract heat from the surrounding air.
Ground-source heat pump hot water systems source heat from underground, via buried coils. These systems can be more efficient than air-source heat pumps but can be much more expensive, so in most cases they’re not viable. This system is worth considering if you are looking at both water and space heating.
Heat pump hot water system configuration
There are two configurations for heat pump hot water installation:
- Integrated systems
- Split systems
Split-system heat pump hot water systems are where the evaporator, fan and compressor components are located in a separate housing and connected to the water storage cylinder by refrigerant piping.
For integrated (one-piece) heat pump hot water systems, the evaporator, fan, compressor and condenser are mounted on top or beside the water storage cylinder.
Integrated units are simpler to install and more compact; however, they are much heavier than split system units, for obvious reasons. Split system units provide greater flexibility when it comes to installation because of the separate components. For example, you could have the water storage cylinder located inside and the pump components outside.
Due to design, there are limitations when it comes to repairing integrated heat pump hot water systems.
Hot water heat pump installation
Integrated heat pump hot water systems are installed on the ground outside. ‘Split-system’ heat pump hot water systems can have some components installed inside, however, this is optional. Either way, they must be installed in a well-ventilated area, for continuous access to ambient air for obtaining heat.
Heat pump hot water noise
When considering the location, it’s important to note that heat pump hot water systems do generate noise when operating. The noise is comparable to a modern refrigerator and depends on the size, brand and model of the system.
Depending on your settings, the water heating process can activate at any time of the day (or night), so installation near bedrooms should be avoided if this bothers you. Consider the neighbour’s bedroom location too!
Heat pump hot water in cold climates
Heat pump hot water systems operate more efficiently and heat water more quickly when the outside air temperature is higher. They do work in cooler temperatures; however, some models use an electric element as a booster if temperatures fall too low. These models use more energy, incurring higher running costs.
Heat retention and reheat rate can also be affected in cooler climates because of the lower temperature of your cold water supply and lower ambient air temperature outside.
There are models designed for cooler climates. If you live in a cooler area, Solstra’s experienced technicians can provide advice on brands that are the most tolerant and energy efficient in the cool.
The right size for your needs
Inevitably, all hot water systems lose some heat through the walls of the water storage cylinder, so it’s important to consider your usage patterns to minimise energy wastage on heating water that is not used.
For example, if you are only heating water at night, your heat pump hot water installation should be big enough to accommodate your daily water requirements. If you plan on heating multiple times a day, a unit with a smaller tank that takes less time to heat might be a better option.
Always engage a licensed electrician for your hot water heat pump installation. Only a licensed electrician has the qualifications to install a safe and compliant electric circuit for your hot water service.
