Geothermal Heat Pump System
In principle, a geothermal heat pump functions like a conventional heat pump, by using high-pressure refrigerant to capture and move heat between indoors and out. The difference is that conventional systems gather their heatand get rid of itthrough the outside air. Geothermal systems, in contrast, transfer heat through long loops of liquid-filled pipe buried in the ground.
Do Air Source Heat Pumps Work In Winter
Air source heat pumps harvest heat from the ambient air. So, if the ambient air temperature drops too much, for instance in winter, air source heat pumps may take longer to heat up the water to the desired hot water temperature.
Usually, the minimum ambient air temperature air source heat pumps can work is about -25°C. Beyond that, air source heat pumps may stop producing hot water entirely.
Heat Pump Water Heaters Vs Tankless
Many people that consider heat pump water heaters also look at tankless water heaters . Thats because both are more energy efficient than conventional gas and electric water heaters. Therefore both lead to savings over the long run.
So how do heat pump hybrid water heaters compare to tankless water heaters?
More immediate capacity
The best heat pump water heaters on the market offer much more immediately hot water capacity than tankless water heaters.
Lets say you and your family get home from a camping trip or a soccer game and everyone wants to shower at once.
If you have a heat pump water heater, no problem. The Rheem 50 gallon water heater for example can give you 4 back to back showers.
But if you bought a low GPM tankless water heater your family will likely run into problems when three of you go to shower at once.
There are tankless water heaters that offer as much as 10 GPMs, but they start to get pricey. So if you need a lot of hot water at once, the heat pump water heater is the way to go.
Lower carbon footprint
While tankless water heaters are more energy efficient than conventional gas and electric water heaters, they still cant beat hybrid water heaters.
The average heat pump water heater emits about half as much CO2 compared to on-demand water heaters . Why? Heat pump water heaters move heat whereas on-demand tankless water heaters generate heat.

The Upfront Price And Expected Payback Period
As stated above, the starting price of a heat pump system may be enough to deter unsure homeowners. However, it is very important to put the price of your system into relative terms in comparison to what you are currently paying to have your hot water heated. Depending on your location, a typical home in Australia will heat its water with either electricity or natural gas.
In some parts of the country, these resources can be extremely expensive, with higher priced tiers costing heavy users hundred of dollars per year on their utility expenses. With a heat pump hot water heater, your dependence on the local utility diminishes, so that you become free and unaffected by future rate changes.
What is crucial to understand here is that you are already paying to have your hot water heated. By running a calculation of your homes future energy costs versus the expected lifetime of your hot water heater, you are likely to determine that installing a heat pump system may provide you with the best overall long-term economic advantage.
How Long Does An Air Source Heat Pump Takes To Heat Water
How long an air source heat pump takes to heat water to a desired hot water temperature depends on several factors as follow:
- The higher the desired hot water temperature, the longer it takes.
- The lower the house’s cold water temperature, the longer it takes.
- The bigger the hot water tank , the longer it takes.
- The greater the air source heat pump water heating capacity, the faster it takes.
For instance, if you have a large hot water tank, it’ll take an air source heat pump longer to heat all of the water inside the tank to 60°C. Also, if the air source heat pump heating capacity is lower, it’ll take longer to heat up the water too.
Nonetheless, as a rule of thumb, 1 kW of air source heat pump water heating capacity produces 26 litres of hot water in an hour given that the cold and hot water temperatures are 27°C and 60°C respectively.
Assuming that an air source heat pump has a water heating capacity of 10 kW, it can produce 260 litres of hot water in an hour. So, if you have a 100-litre hot water tank, the air source heat pump needs 23 minutes to heat all of the water inside the tank from 27°C to 60°C.

Suitable Conditions For Heat Pumps
These systems can be used throughout Victoria, but they will operate more efficiently and heat the water more quickly when the outside air temperature is higher.
There are no energy rating labels for heat-pump hot water systems. There are two schemes that require them to be tested for efficiency: the Small-scale Technology Certificate scheme and the Victorian Energy Upgrades scheme.
Geothermal Heating And Cooling
As our cave-dwelling ancestors discovered long ago, if you go far enough underground, the earth’s temperature stays at a constant 50 degrees or so, no matter how hot or cold it gets outside. So while a conventional “air-source” heat pump struggles to scavenge heat from freezing winter air or to dump it into the summer swelter, its “ground-source” counterpart has the comparatively easy job of extracting and disbursing heat through the 50-degree liquid circulating in its ground loop.

How To Extend Your Heaters Life Span
When youre spending large sums of money on a water heater, its in your best interest to take the steps necessary to extend that heaters life cycle for as long as possible to avoid purchasing a new one.
- Invest in a quality heater. The best way to ensure you get your moneys worth out of your water heater is to invest in a quality one. If you seek out the cheapest water heater on the market, the chances are that you will get what you pay for and end up needing to purchase a new one before you would normally.
- Get your heater serviced regularly. As with any home appliance, you should aim to get your heater serviced regularly. These heaters should be serviced by a plumbing professional at least once a year. This is to ensure the longevity of your heater and the quality of your hot water. Goodbee Plumbing offers many different services for all of your plumbing needs.
What Is A Gas Water Heater
A gas water heater works through convection. The cold water at the bottom of the tank is heated by a gas burner which is located just below the sealed tank.
As the waters temperature gets warmer, it rises in the tank, and the discharge pipe then draws it to where you need hot water in your house. Gas water heaters only use gas and require no electricity to operate.

However, none of this guarantees that a multiyear investment in designing, manufacturing and marketing a brand-new product line will pay off for manufacturers.
This technology, like any emerging technology, was experiencing this chicken-and-egg problem, Khanolkar said. Without a real product, the utilities would not provide incentives to cover the extra upfront cost for heat pump water heaters compared to gas-fueled versions. And without the demand generated by incentives, manufacturers would not fully invest in the product.
Thats why the Building Decarbonization Coalition chose to engage early in 2018 with Rheem and other water heater makers on getting prepared for Californias electrification policy push, Bartholomy said. They saw that there were the right people at the table who were going to ensure that the policy changes would be made and that the program would be deployed in a way that would ensure the demand would be there for them.
Californias ongoing policy actions helped keep up the confidenceto stick with the project, he added. Those policies included heat pump incentive programs aimed at contractors as well as homeowners, along with a statewide building code that set heat pump water heaters as the standard for efficiency.
Manufacturers typically operate on five-year cycles, he said. How can you build trust and act on the market and policy changes that are necessary to give them confidence to move forward?
