Sizing Your Electric Tankless for Well Water: Getting It Just Right
Okay, so you’re considering an electric tankless water heater for your well water setup. Fantastic choice! But before you jump in, let’s talk sizing. This isn’t a one-size-fits-all situation, especially with well water’s sometimes unpredictable flow rates and temperature. You need to know your household’s peak demand. Think about those mornings when someone’s showering, the dishwasher’s running, and maybe someone’s even starting a load of laundry. That’s peak demand, and your water heater needs to handle it.
Figuring this out involves calculating your “flow rate.” Each appliance uses a certain gallons-per-minute (GPM) of hot water. A standard showerhead uses about 2.5 GPM, a kitchen faucet around 1.5 GPM, and a washing machine roughly 2-3 GPM. Add up the GPM for all the appliances you’re likely to use simultaneously. This sum is your target flow rate. Don’t forget to factor in the temperature rise needed – the difference between your incoming well water temperature and the temperature you want your hot water to be.
Now, why is this so important? Well, if you undersize your tankless heater, you’ll end up with lukewarm showers and disappointed family members. Imagine turning on the kitchen faucet for hot water while someone’s showering, only to have the shower suddenly turn cold. Not fun, right?
