Why Should You Get A Heat Pump Hot Water System For Your Home?

Published on:
November 3, 2023

Selecting the right hot water system for your house is super important. You must choose how to heat the water and decide between keeping it in a tank or flowing continuously. Also, consider the size, cost, and how much energy it uses. 

One type of system is called a heat pump. It works by moving heat from one place to another using a particular machine and various cool liquids or gases.  

But why should you get a heat pump hot water system for your home? Should you get it? Well, let’s try to answer the questions.  

Heat pumps are better because they don’t use a lot of energy. Heat pumps are becoming increasingly prevalent worldwide because they help save money on energy bills 

If you’re considering getting a new hot water system, this article talks about the essential things to think about before deciding on a heat pump system.

What is a Heat Pump Water Heater?

A heat pump is fundamentally a backward refrigerator. It takes heat from the air and moves it into a tank to heat water. It can transfer heat from a chilly place to a warmer one.  

Not only that, but it can also cool a home by removing heat and sending it outside. 

When heating, the pump squeezes the outside heat, making the pump’s fluid very hot. This hot energy is sent inside to warm the water and then sent outside again. Heat pumps are eco-friendly and efficient 

A COP number measures their effectiveness. Higher numbers mean it uses less energy.  

Components of A Heat Pump

A heat pump water heater is a simple system made up of nine main parts: 

Tank: This is a big container for water, like in a regular water heater. 

Compressor: It’s at the top of the heat pump. It pressurises a special liquid, making it heat up and move through the system. 

Evaporator: These coils are near the top of the pump and get warm air from the surroundings. The liquid heats up, gets pressurised, and turns into a gas, creating high pressure and heat. 

Condenser: These coils are around or inside the water tank. The hot gas cools down, turns back into a liquid, and gives its heat to the water in the tank. 

Fan: It pulls warm air from your basement, storage room, or garage. 

Thermostats: There are usually two. They check the water temperature at the top and bottom of the tank. They control whether to heat the water or stop heating it. 

Cold Water Inlet: It’s where cold water enters from your home’s main line. 

Hot Water Outlet: This is where heated water leaves the heater to go to your shower, sink, washing machine, or dishwasher. 

Drain: If you need to empty some water from the tank, this is where you release it.  

Types of Heat Pump Hot Water System

Different kinds of hot water systems exist, including heat pump water heaters. These systems vary based on where they get their energy and the type of unit used. 

There are three main types of heat pumps based on their energy source: air-source, water-source, and geothermal.  

Air-source heat pumps are the most common in Australia and work by extracting heat from the air. They are effective in many areas but might not suit freezing climates.  

On the other hand, geothermal heat pumps get heat from the ground, which remains warmer and more consistent in temperature. While more expensive initially, they are efficient and cost-effective in the long run.  

Water-source heat pumps rely on available groundwater, making them less common but a great option if your home meets the requirements. 

Air-source heat pumps are more commonly installed, have lower initial costs, and are suitable for various climates between the three types.  

Meanwhile, geothermal and water-source heat pumps are more efficient but might require more investment and specific conditions for installation. 

Heat pumps can also be categorised as integrated or split systems. Integrated systems have the pump and tank connected as a single unit, while split systems have these components separated.  

Split systems offer installation flexibility, particularly for homes with limited outdoor space. On the other hand, integrated systems are easier to install but might need less plumbing work as the tank and pump are already connected. 

Pros of Heat Pump

They use less electricity so that you can save on energy bills. If you use them with solar panels, they can be more than 300% efficient. 

Less Maintenance

They only require a little maintenance. You’ll only need a professional to check them every 3–4 years. It’s easy for the owner to check the parts. 

Saves Energy

They don’t make heat. They move it around, which means they use less energy and make fewer harmful gases than other systems. 

Safer

They’re safer than other systems because they don’t need fuel. So they have fewer safety risks. 

Reduces Pollution

Air source heat pumps don’t use much power – they get their power from the air’s temperature outside. This can cut your electricity use and carbon footprint a lot. 

Year-round Service

These systems work as a heater in winter and an air-con in summer. Great for places with significant temperature changes. 

Long Lifespan

They’re known for lasting more than 20 years. They start saving you money immediately and only need service once a year. 

Improves Energy-Efficiency

Try additional energy-saving tips to help lower your water heating bills after your water heater has been installed and maintained. Some energy-saving devices and systems are less expensive to install alongside the water heater. 

Cost-effectiveness and Lifetime Savings

Heat pumps are considered cost-effective due to their energy efficiency and potential for long-term savings—the lower energy consumption results in significant savings on electricity bills. Despite higher initial costs, the reduced operating expenses and energy savings over the years can make heat pumps more cost-effective in the long run. 

Installation and Maintenance

Setting up and caring for your heat pump hot water system is crucial for making it work efficiently. A proper installation depends on the fuel you use, the weather where you live, and the rules for building and safety in your area.  

That’s why it’s a good idea to get a qualified professional, like a plumbing and heating contractor or a geothermal heat pump expert, to set up your heat pump system. 

Here’s what to do when choosing the right professional: 

  • Ask for written cost estimates 
  • Request references from them 
  • Check if the company is reputable  
  • Ensure they’ll get any necessary permits and understand local building codes. 

Regular maintenance for your water heater is essential, too. It helps your heater last longer and work better. You can find specific instructions for keeping in the owner’s manual.  

Can a Heat Pump Run on Solar Energy?

Heat pumps combined with solar panels offer an environmentally friendly way to cater to space heating and hot water needs at home. You could also generate surplus energy to meet your energy needs. 

Solar power is broadly categorised into thermal solar energy and photovoltaic solar energy. Utilising solar thermal energy to heat your water significantly reduces the electricity demand of your heat pump. 

On the other hand, photovoltaic solar panel systems directly capture the sun’s energy, converting it into usable electricity. This electricity can supplement the power used by your heat pump.  

It will decrease your dependence on grid electricity and reduce fossil fuel usage. 

In Australia, solar panels are increasingly popular among homeowners. Homeowners also favour heat pumps.  

These devices also extract heat from the surrounding air or the earth’s core, utilising renewable energy or solar panels.

Heat Pump Hot Water FAQs

How Does a Heat Pump Water Heater Differ from a Conventional Water Heater?

In contrast to a standard water heater that creates heat directly, a heat pump water heater doesn't generate heat from the beginning. Instead, it utilises the natural warmth present in the air to heat a refrigerant, which, in turn, heats the water. This method, although intricate, proves to be a significantly more effective approach to warming water. 

What is the Cost of A Heat Pump?

The price of a heat pump system in Australia can change based on its size and functionalities. It can typically cost around from $1,500 to $5,000. 

Will a Heat Pump Actually Save Me Money?

Yes! Heat pumps will save you money or your monthly bills regularly. It will save you money in the long run, too.  

Are heat pumps better for the environment?

Heat pumps do not require fuel. Hence, they are environmentally friendly. They generate heat and transfer it to water using environmentally friendly refrigerants. 

Traditional hot water systems require fuel combustion, which produces soot, which is harmful to the environment. Heat pumps, on the other hand, simply extract heat from their surroundings and transfer it to water.
