Cold Weather and Your Tankless Water Heater

One question that many people ask when they are choosing a new water heater is: are tankless water heaters worth it?  A tankless water heater is a must-have addition to any home, especially for those that find themselves in areas with particularly bitter winters.

Tankless water heaters may require additional attention during cold weather to prevent them from freezing or experiencing other weather related problems. Recommendations may vary between manufacturers, so it’s important to check your owners manual for details on your specific unit.
