You need enough heating power to raise the incoming water temperature (which is already cold!) to a comfortable level without sacrificing flow rate.
Imagine you’re taking a shower and someone flushes the toilet or starts the dishwasher. In a poorly sized system, your shower water could suddenly turn icy cold. This is because the heater is struggling to keep up with the increased demand, and it prioritizes the new draw. A correctly sized unit will handle these multiple demands with ease, ensuring everyone enjoys consistent hot water.
Calculating your flow rate needs is key. Consider how many hot water appliances you might be using simultaneously. Is it just you taking a shower in the morning, or are you also running the dishwasher and the washing machine? Add up the gallons per minute (GPM) for each appliance to get a total demand. Then, factor in the temperature rise needed in your area. The colder your incoming water, the higher the temperature rise required, and the more powerful the heater you’ll need.
Don’t underestimate the impact of cold incoming water. In some northern states, the incoming water temperature can be as low as 35 degrees Fahrenheit. That’s a huge difference compared to warmer climates. Failing to account for this can lead to disappointment, as your “powerful” heater might still struggle to deliver satisfying hot water during the coldest months. Consider consulting with a plumber or electrician to get a professional sizing recommendation based on your specific needs and location.
Installation Challenges in Cold Weather: Prepping for Success
Installing an electric tankless water heater in cold climates presents some unique challenges that aren’t always obvious. Think about working outside in freezing temperatures – tools are harder to grip, materials become brittle, and fingers lose dexterity quickly. It’s a different ballgame than a summer installation.
One of the biggest challenges is protecting the unit itself during installation. Leaving it exposed to freezing temperatures, especially if it contains any residual water from testing, can cause internal components to crack or break. Wrap the unit in blankets or bring it inside whenever possible to prevent damage.
Proper insulation is also crucial. Any exposed pipes carrying water to and from the heater are vulnerable to freezing. Frozen pipes can burst, causing significant water damage and interrupting your hot water supply. Insulate all pipes thoroughly, and consider using heat tape in areas prone to extreme cold.
Don’t overlook the electrical requirements. Cold weather can affect the performance of electrical wiring and components. Make sure all connections are secure and properly insulated to prevent shorts or other electrical problems.

Let’s find you a tankless champion that can handle the winter chill and keep you cozy all year long!
1. GPM (Gallons Per Minute) – Know Your Flow!
Alright, first things first, let’s talk flow rate. This is probably the most crucial factor, especially when the water coming into your house is practically ice water! GPM basically tells you how much hot water the unit can produce at a specific temperature rise. Imagine trying to take a shower while someone’s doing laundry and washing dishes – a low GPM means you’ll be competing for hot water, and nobody wants that! So, how do you figure out your ideal GPM?
Think about all the hot water appliances you might use simultaneously. Showering typically requires 2-3 GPM, a faucet uses around 1-2 GPM, and your dishwasher or washing machine can need 2-4 GPM. Add up the highest possible combination you’d realistically use at the same time. Then, consider the incoming water temperature. Colder climates mean the unit needs to work harder (and faster!) to heat the water to your desired temperature. You’ll want to choose a unit with a GPM that can handle your peak demand, even when the incoming water is at its coldest. This is where finding the best electric tankless water heaters for cold climates is imperative.
2. Temperature Rise – Bridging the Cold Gap
Next up, temperature rise! This is directly related to GPM, but it deserves its own spotlight. Temperature rise refers to how much the water heater can increase the temperature of the incoming water. Let’s say your groundwater temperature is a bone-chilling 40°F (not uncommon in some colder areas!). And you want a nice, comfortable shower at 105°F. That means you need a temperature rise of 65°F.
Make sure the unit you choose can actually handle that temperature rise at your desired GPM. Some units might boast impressive GPM numbers, but that’s only at a lower temperature rise. Check the manufacturer’s specifications carefully! They’ll usually have a chart or graph showing the GPM at various temperature rises. Don’t just look at the maximum GPM.
