Determining the best size heat pump water heater isn’t as complex as it might initially seem. The main thing you’ll need to do is figure out how much water your household demands.
Specifically, you’ll need to find your home’s peak hour demand. This is the time of day that you and your family use the most hot water for whatever activities you are using it for.
This could be when people wash dishes, do laundry, take showers or anything else that requires a large amount of hot water. Think about an average day in your home, when hot water is used and how much of it is used during the busiest hour of the day.
You will want to imagine the day in three sections – morning, afternoon and evening – and pick the time of day that water is used the most. This will help you select a heat pump water heater that fits your needs and can supply you with the water you need to satisfactorily complete your tasks.
Next, calculate the amount of water your family uses during those busy times. Consider each activity done and how much water is used during that activity. Naturally, households with many family members will use more water than households with smaller families.
Once you know the average amount of water your family will use, you can then start looking for a water heater that can accommodate your needs. Look for a water heater that can keep up with your family’s demands.
If you’re having trouble determining how much water a specific heat pump water heater will supply in an hour or short period of time, we recommend speaking to your water heater supplier directly to ask any questions you have.
Don’t forget to think about the water heater’s physical size as well. Be sure that you have enough space to install your new water heater safely and correctly.
Simply put, the three things you need to think about are:
Your Household’s Water Demands. How much water does your household use during its busiest hours? Always select a water heater that can provide you with the water you need.
Your Water Heater’s Water Output. How much water can your potential water heater create in a short amount of time? It should keep up with your needs.
Your Water Heater’s Physical Size. Do you have enough space for your water heater to be safely installed? Always check the physical size of your water heater before you purchase it.
