Best Electric Tankless Water Heater For Cold Climates (2024 Update)

When selecting the best electric tankless water heater for cold climates, there are a few key factors to consider before making a purchase. The most important aspect is ensuring the model you choose has sufficient power to heat water to the desired temperature, even when dealing with very cold incoming water temperatures. You’ll also want to select a unit with freeze protection and condensation prevention features to avoid any issues during frigid winter months.

Does an electric tankless water heater make sense for your home, budget, and climate? What size unit will meet your household’s hot water demands? How difficult is the installation process and what electrical upgrades might be required? Knowing the answers to these questions ahead of time will ensure you select the right tankless heater.

Additionally, think about your needs in terms of flow rate, activation flow rate, and temperature rise. Will a standard 5-6 GPM unit suffice or do you require higher flow rates? How many sinks, showers, and other fixtures might be running simultaneously? For cold regions, point-of-use heaters at each fixture may be preferable to a whole-house model. Carefully considering these factors will lead to making the optimal electric tankless water heater purchase for cold weather usage.

However, it's important to note that the efficiency of both types of water heaters depends on various factors, including the size of the unit, the level of insulation, and the specific climate conditions. It's always best to consult with a professional to determine the best option for your specific needs and location.

How do I properly size an electric tankless water heater for cold climates?

Sizing an electric tankless water heater for cold climates is an important task that should be done carefully to ensure that you have a sufficient supply of hot water in your home. The first step is to determine your required flow rate, which is the volume of hot water you need at any given time. This is typically measured in gallons per minute (GPM). Once you have determined your required flow rate, you should consider the temperature rise, which is the difference between the temperature of the incoming cold water and the desired hot water temperature.

For cold climates, it is important to choose an electric tankless water heater with a high enough heating capacity to provide enough hot water even in low temperatures. You should look for a heater with a high enough temperature rise to compensate for the lower incoming water temperature. Additionally, you should consider the size of your household and the number of hot water fixtures in use at any given time.

It is recommended to consult with a professional plumber or electrician to properly size and install an electric tankless water heater in cold climates. They can help you determine the specific requirements for your home and ensure that the installation is done correctly.

How does cold weather affect the performance of electric tankless water heaters?

Cold weather can have a significant impact on the performance of electric tankless water heaters. As the temperature drops, the incoming water temperature also decreases, making it more difficult for the heater to warm the water to the desired temperature. This can result in a reduced flow rate and longer wait times for hot water.

To combat this, some electric tankless water heaters have a freeze protection feature that prevents the water from freezing in the unit. This feature typically activates when the temperature drops below a certain level, and it can help to prevent damage to the heater.

Additionally, it is important to properly insulate the pipes and the unit itself to help retain heat and prevent heat loss. This can improve the efficiency of the heater and reduce energy costs.

Overall, while cold weather can impact the performance of electric tankless water heaters, there are steps that can be taken to mitigate these effects and ensure that the unit continues to function properly.
