How to choose the best tankless water heater for your home?
There’s a number of factors to consider:
First of all, you need to understand that size doesn’t matter for tankless water heaters. Their “capacity” is defined by the flow rate that they can heat to a certain temperature.
When you look at the specs, pay attention to the number of GPMs (gallons per minute) at a certain temperature rise.
By the way, the temperature rise is the second (or the first, depends on the perspective) factor that you need to figure out.
The temperature rise is the difference between the temperature of the water that comes from the ground (inlet water temperature) and the temperature of the water that that you want to get in your shower.
So, to determine the right size of the tankless water heater, do this:
- Find out the groundwater temperature in your region.
- Determine what temperature you want to get in your shower or faucet or whatever you want touse it for.
- Subtract one number from another. You’ll get the temperature rise.
- Find out how much hot water max you are going to need simultaneously in gallons.
- Choose the right model that fits all your requirements.
For example, a normal shower consumes about 2.5 GPM on average. The kitchen faucets may take additional 1.5 gallons per minute.
So, if you want to use two showers at the same time and use the kitchen faucet, you’re going to need a tankless water heater that can heat 6.5 gallons per minute.
Keep in mind that very often manufacturers mentions only the maximum possible GPM number that is relevant for states with hot weather and hot ground water.
That’s why you need to find a tankless water heater that handles your hot water demand at the temperature rise for your region.
