Tank vs. Tankless: Choosing the Right Water Heater for Your Home

Tank vs. Tankless: Choosing the best Water Heater for Your home as a home owner in anchorage alaska

When it comes to selecting a water heater, homeowners are faced with a significant choice: the traditional tank water heater or the modern tankless version. Both types offer unique benefits and potential drawbacks. At Diamond Heating, Anchorage’s leading expert in heating and cooling solutions, we provide both tank and tankless water heaters, equipped to meet the specific needs of every household. Here’s a comprehensive comparison to help you decide which water heater is right for your home.

Tank Water Heaters: Reliable and Cost-Effective


  • Consistent Supply: Tank water heaters store a significant amount of hot water, ready for immediate use. This can be especially beneficial for families requiring a steady flow of hot water for multiple simultaneous activities.
  • Lower Initial Cost: Generally, tank water heaters cost less to purchase and install compared to tankless models, making them a budget-friendly option for many.
  • Simplicity: Tried and true, tank water heaters are a solid choice. With fewer complex components, tank water heaters are easier to maintain and repair.


  • Space Requirement: These units require more space due to their large size, which can be a drawback in smaller homes.
  • Energy Consumption: Tank models continuously heat the water, leading to higher energy consumption and costs, especially during periods of non-use.

Tankless Water Heaters: Efficient and Space-Saving


  • Energy Efficiency: Tankless water heaters provide hot water on demand, heating water only when it’s needed. This can reduce energy consumption by up to 30%, making it a more eco-friendly option.
  • Space-Saving Design: These heaters are compact and can be mounted on a wall, freeing up floor space for other uses.
  • Longevity: Tankless models typically have a longer lifespan than their tank counterparts, often lasting up to 20 years with proper maintenance.


  • Higher Initial Investment: While they offer long-term savings, tankless water heaters have a higher upfront cost for the unit and installation. Thankfully we have 0% APR for 36 months for Tankless On Demand Water Heaters.
  • Limited Output: Depending on the model, tankless systems might struggle to supply sufficient hot water for simultaneous multiple uses, such as showering and running the dishwasher at the same time.

What’s Best for Your Home?

Choosing between a tank and tankless water heater depends on several factors:

Household Size and Water Usage: Larger families might benefit from the robust supply a tank model offers, while smaller households or those seeking energy savings might prefer the efficiency of a tankless system.

Budget: Consider both the initial investment and potential energy savings. Tankless heaters cost more upfront but typically lead to lower utility bills.

Space Considerations: If space is a premium in your home, a tankless model’s compact size could be a deciding factor.

Emergency Preparedness: For those in areas like Anchorage, where power outages can be a concern, gas-powered tank models can still operate without electricity, providing a crucial advantage.
