When you’re considering a new water heater, there are several factors for you to consider to determine which size you require. This includes the number of people in the household, peak water usage and energy consumption.
In this blog, we discuss these points in detail so that you can determine which size best suits your needs.
- Determine your peak hot water usage: This refers to the amount of hot water the household will use during peak demand, for instance, in the morning when multiple family members require hot water for showering or other purposes.
- Estimate the hot water usage per activity: The next step involves estimating the amount of water each activity uses. Below are some examples:
– Bath: 100-150 litres
– Shower: 10-30 litres/min
– Dishwasher: 10-20 litres/cycle
– Washing machine: 40-60 litres/cycle
– Hand washing dishes: 5-10 litres/min
- Calculate the total amount: With the estimated peak demand usage per activity above, calculate the total volume of hot water needed.
- Consider recovery time: Hot water heater requires a recovery time to reheat the water once it has been depleted. If you have a higher demand for hot water, it may be best to consider a larger water heater with a faster recovery time.
- Efficiency rating: To reduce energy consumption and operational costs, look for a water heater with a higher energy efficiency rating.
Once you have followed the steps above, such as determining your peak water consumption and considering recovery time and energy efficiency, you should be able to select a water heater that best suits your needs.
