When it comes to picking the right hot water system for your home, it’s important to consider your household’s unique needs. Every home is different, and these differences impact the size of the system that’s appropriate for you. In this user-friendly guide, we will help you choose the right-sized hot water system based on government recommendations.
Understanding your households needs.
Only you know what goes on inside your household on a day to day basis. Factors such as the number of people and your hot water usage. The key is to think beyond only focusing on shower usage.
- How long do the people in my household spend in the shower?
- Does my household only shower once per day?
- Do any of my household members take regular baths?
- Do my plumbed appliances such as the dishwasher and washing machine use hot water from the tank?
If any of these factors apply to your household then you may want to consider a larger unit than the manufacturer’s recommended size due to your high hot water consumption.
Although the number of people is the biggest factor in your household’s hot water usage, we recommend going off of the amount of bedrooms in your home. This is because the amount of occupants may change over time and with them the demand for hot water.
|Number of Bedrooms||Recommended Tank Size|
|5 or more||More than 375 litres|
What else should you consider?
Existing hot water system:
Tank system: Take into account the size of the tank when considering replacements.
Instantaneous system: Consider your household’s hot water usage when looking at replacements.
Choose a suitable location for your system that considers your own comfort and your neighbours’ peace. Please note that all of our heat pump systems are required to go outside of the house. In no circumstance are they able to be installed inside the home.
Solar and timers:
Heat pumps often have timers to optimise electricity from solar panels. Larger tanks may be needed for households using timers to avoid running out of hot water between reheating times.
Some heat pumps have booster elements that speed up water heating, which can be beneficial in colder climates but may increase running costs.
Local climate affects energy consumption and performance of hot water systems. Heating water in colder climates may take longer, so discuss with your customer service representative to find models and sizes suitable for your climate.
Daily usage patterns:
Consider how your household uses hot water, such as showering length and patterns. Heat pumps fill with cold water from the bottom and draw hot water from the top. Tanks can take 1-3 hours to refill and heat the water if completely drained. If people in your household currently take showers back-to-back, your tank will be required to refill and heat between showers.
