Do Outdoor Tankless Water Heaters Freeze in Michigan?

post img

When it comes to ensuring your home has access to the hot water it needs, homeowners typically have two options of tankless water heaters to choose from: indoor units and outdoor units.

While outdoor tankless water heaters can be a great choice for Michigan families, the local climate can present some challenges for keeping these systems in proper working condition — especially during periods of below-freezing weather.

In this blog post, the plumbing experts at Service Professor discuss what Michigan families can do to keep their outdoor tankless water heaters from freezing during winter so they can get the most out of their systems.

Benefits of Outdoor Tankless Water Heaters

An outdoor tankless water heater is installed outside the home and is capable of withstanding extreme weather conditions. Here are a few benefits of installing an outdoor tankless water heater:

  • Life span: Contrary to popular belief, outdoor tankless water heaters boast a life span comparable to indoor units, lasting up to 20 years with proper maintenance.
  • Durability: Complete with an aluminum enclosure that’s rust-resistant and weatherproof, an outdoor tankless water heater is incredibly durable and can survive extreme weather conditions.
  • Space: Since the unit is installed outside, outdoor tankless water heaters offer greater space savings for families in smaller homes looking to maximize storage capacity indoors.

Does an Indoor Tankless Water Heater Make More Sense for You?

While outdoor tankless water heaters can survive extreme weather, an indoor unit may make more sense for Michigan families given the prolonged period of below-freezing weather the region is known for.

Indoor tankless water heaters are easier to protect from freezing and require less maintenance since they’re shielded from the elements.

If you’re unsure whether an indoor or outdoor unit is best for your specific needs, consult with a knowledgeable plumber to understand your options and make the best decision.

Protect Your Outdoor Water Heater

If you decide a tankless outdoor water heater is right for your home, it’s important that you take the necessary precautions to keep it from freezing during the harsh Michigan winters.

Here are a few steps to take to ensure your unit doesn’t freeze:

  • Drain the system: Shut off the water and gas supply to the unit, then drain any remaining water from the unit to prevent freezing and internal damage.
  • Cover the unit: Cover your tankless water heater with an insulated, weatherproof enclosure to keep it protected from extreme temperatures, snow, and ice.
  • Insulate water pipes: Ensure the water pipes leading to and from your system are adequately insulated to trap heat and prevent your unit from freezing.
  • Clear away buildup: Inspect for snow and ice accumulation around the unit and clear it away quickly to safeguard your outdoor unit from winter-related issues.
