There are many benefits that come along with a tankless water heater installation. These heaters provide a constant flow of hot water, use less electricity, last longer, provide tax breaks and take up less space in your home. But how do you know what size heater is right for you? To help you make this decision, here are some important factors to consider:
- The size of your home
- Your home’s rate of water flow
- The size of your household
The Size of Your Home
Larger homes with several bathrooms typically use more hot water. If you have a home with more than one bathroom, you want to make sure that the tank you choose has a power range large enough to supply plenty of hot water to multiple bathrooms.
To guarantee complete efficiency and consistent hot water for every room in your house, the size of the heater should always relate to the size of your home. The bigger the house, the bigger the tankless heater required.
Your Home’s Rate of Water Flow
Because tankless water heaters work by steaming water as it runs into your house, your home’s water flow rate is directly related to the flow rate of your water heater. If you want to be able to run multiple showers or faucets at once, without sacrificing water flow speeds, your tankless heater will need to be large enough to have a higher flow rate that can handle several running appliances.
You can calculate the required water flow rate of your tank by adding the flow rate of your home’s appliances together. For example, if you want to run a shower with a flow rate of 1.8 GPM (gallons per minute) at the same time as a faucet with 1.0 GPM, you will need a tankless heater that can provide at least 2.8 GPM.
The Size of Your Household
If you have several people living in your home or if you regularly have guests over, you need a tankless water heater that can accommodate everyone. Even if you don’t personally need hot water constantly, in times of high water usage, you’ll want to know that your tankless water heater is big enough to handle the task.
