Tankless Water Heaters vs. Tank Water Heaters

At CastleWorks, we understand that selecting the right water heater is an important decision for California homeowners. Whether they are seeking both comfort and efficiency, CastleWorks has provided you with this easy to follow guide. As a trusted partner in home improvement, we’re here to walk you through the gas and tankless water heater pros and cons. Let’s explore the considerations that can help you make an informed choice for your home.

Electric Tankless Water Heater


  • Energy Costs: CastleWorks recommends tankless water heaters for those looking to reduce energy consumption. An electric tankless water heater does not need to constantly heat and store water in a tank as do tank water heaters. The tankless will only operate when someone needs hot water saving you on extra costs.
  • Space-Saving Design: Compact and wall-mounted, tankless models save valuable space, providing flexibility in installation. They are typically about 15 to 30 inches in width and 20 to 30 inches in height making it easy to store.
  • Extended Lifespan: Enjoy long-term durability with a tankless water heater. Since it is not running all the time, tankless units usually last longer than tanked units. 
  • Endless Hot Water: No more concerns about running out of hot water. Tankless heaters provide a continuous supply of hot water! With a tankless, cold water flows through the unit heating it instantly.


  • Initial Investment: While the upfront cost may be higher, think of it as an investment in long-term energy savings. With the advanced technology that a tankless brings it can acquire additional installation considerations.
  • Installation Complexity: Tankless water heaters may require specialized installation, including upgrading electrical or gas lines to accommodate the higher power demands. Additionally, they often need adequate ventilation for proper operation, which can add complexity to installation.
  • Flow Rate Considerations: The flow rate of a tankless water heater determines how much hot water it can provide at once. If multiple appliances are using hot water at the same time, a tankless unit may struggle to keep up with demand. This leads to reduced water pressure or temperature fluctuations.

Tank Water Heater: Classic Reliability


  • Cost-Effective: We know budgets matter to California homeowners. Tank water heaters are a cost-effective option, offering reliability without breaking the bank. They are simpler in design and have been around much longer leading to affordable costs.
  • Straightforward Installation: Tank units have simpler installation practices making it the easier out of the two to install. Most HVAC professionals are familiar with these installations because of how often water heaters have been around.
  • Consistent Supply: With a tank, you’ll enjoy a steady stream of hot water. Each tank has a recovery rate which refers to the rate at which the water heater can replenish the hot water supply. With a variety of tank sizes, you can find the right water heater to meet the demands of your household effortlessly.


  • Energy Loss: Continuous heating can result in standby heat loss. This happens because heat naturally moves from warmer to cooler areas. This creates the need to consistently heat the water every time it lowers in temperature.
  • Efficiency Concerns: Depending on the energy source, traditional tanks may be less energy-efficient. This usually occurs if electricity is the primary power source. Even if no one is running hot water in the home the tank must use electricity to keep it warm.
  • Maintenance Needs: Regular maintenance is crucial to prevent sediment buildup. Frequent tank flushes are a necessity to ensure a longer lifespan for your tank water heater.
