Tankless doesn't work with cold inlet temperatures.
Do tankless water heaters work in cold climates? If we can deliver hot water to Canada, we can bring it to the U.S. With around 100,000 tankless water heaters sold per year in Canada, our tankless water heaters handle groundwater in cold climates easily. The Tankless Truth™ is, our water heaters will deliver 5 gallons per minute with 40-degree groundwater, equal to running three showers simultaneously.
