Choosing the Right Water Heater: Storage Tank or Tankless?
When it is time to replace your hot water heater, you have the option of a traditional water heater with a storage tank or a tankless water heater. There are advantages and disadvantages to each type of system. We have extensive knowledge of hot water heaters to fully explain your options, help you compare products, and select the best hot water heater for your specific needs, whether for your home or business.
Tankless hot water heaters offer benefits that include:
- Requiring less space for installation
- A constant supply of hot water on demand
- Significantly improved energy efficiency
- Superior energy efficiency
A primary disadvantage of tankless water heaters is their higher initial cost compared to traditional water heaters. While they require a greater upfront investment, tankless water heaters use less energy and have a longer lifespan. The money you save on lower home utility costs and longer equipment life can offset the price difference.

Annual Water Heater Maintenance & Flush Routine
Performing an annual flush on your water heater is a straightforward yet essential maintenance task that helps ensure your unit operates efficiently. Over time, sediment and minerals, particularly in regions with hard water, can accumulate at the bottom of the tank. This buildup can force your water heater to work overtime, leading to increased energy costs, diminished hot water supply, and even a shortened lifespan for the system.
Flushing the tank once a year removes this sediment, which helps:
- Improve heating efficiency
- Extend the life of your water heater
- Reduce the risk of corrosion and leaks
- Ensure a consistent hot water supply
It’s advisable to regularly flush both gas and electric water heaters, as this simple maintenance step can help safeguard your investment and prevent expensive repairs down the line.
Our water heater services keep your system in tip-top shape and ensure you have all the hot water you need. Call Cotti Johnson HVAC, Inc. in Taunton, MA, at 508-301-1831.
