Selecting the right tankless hot water heater is one of the most important energy- and cost-saving decisions a homeowner can make. Tankless water heaters provide hot water on demand, without a large storage tank. Saving you money by heating water more effectively and by eliminating standby losses.
Benefits of Residential Tankless Water Heaters
The benefits of green technologies like tankless hot water heaters (also known as on-demand or continuous flow) are significant. Read on for the top six benefits of residential tankless water heating systems.
#1 -- Cost Saving and Eco-Friendliness
Reduce your heating costs by heating only the water your family needs, not the gallons of water stored in that cumbersome tank in the basement. Many household report a monthly savings of up to 40% off their utility bill. Use less water and enjoy more efficiency with tankless water heaters.
#2 -- Long-lasting Reliability
Tankless water heaters double the lifespan of your hot water heating system. High-quality residential on-demand water heaters typically last for 20-25 years, while traditional tank systems last only 10-12 years.
#3 -- Comfort and Convenience
No more cold showers! Say goodbye to family drama and restrictive bathing schedules; tankless systems deliver an endless supply of hot water where you need it, when you need it.
#4 -- Rest Easy
Eliminate the threat of catastrophic tank failure, leaks and devastating flooding with a tankless water heater.
#5 -- Space Saving
Enjoy more elbowroom and storage space. Tankless water heaters take up significantly less room than traditional tank-model water heaters and can be interior wall-mounted or even installed outdoors.
#6 -- Safe and Pure
Tankless water heaters are equipped with superb safety features, so you don’t need to worry about temperature spikes and painful scalding temperatures. Enjoy clean, pure water, free of rust, scale and dangerous mineral deposits that may accumulate in traditional tank water heaters.
Factors to Consider When Shopping for a Tankless Water Heater
Now that you’ve decided to take the plunge and enjoy the benefits of a tankless water heater, here are a few key considerations to help you select the hot water heater that’s right for you and your family.
#1 -- Size Matters
Even though you don’t need to worry about tank size, you still want to make sure you buy the right system for you needs. Tankless hot water heaters are available by room or in whole-house sizes. To determine the best fit for your family, calculate how many faucets and appliances need hot water.
#2 -- Fuel Type
Like conventional water heaters, tankless hot water heaters are available in electric, natural and propane gas models. If you’re committed to electric, make sure your service meets the unit’s voltage and amperage units.
#3 -- Interior or Exterior
Unlike tank water heaters, tankless systems can be installed indoors or outdoors. Discuss your options with a qualified installation expert to determine the best solution for your household.
#4 -- Venting
Indoor tankless water heaters require special venting to blow exhaust gasses outside. A professional installer will inspect your home for the best possible installation location and venting options.
#5 -- Location, Location Location
The temperature of your ground water affects the speed of your water flow. So, if you live up north, and your ground water runs icy, you’ll need a tankless water heater with a higher maximum flow rate.
#6 -- Multi-Tasking
If weekends mean catching up on chores, then it’s highly likely that the washing machine, dishwasher and shower will be running simultaneously. Factor in a larger gallon-per-minute (GPM) rate to ensure your hot water needs are met.
#7 -- Follow the Incentives
Many utility companies offer incentives for installing energy efficient appliances. You may also benefit from state and federal tax credits and rebates. Do some digging to make sure you get the most bang for you buck.
#8 -- Know What You’re Getting Into
It’s true, a tankless hot water heater will likely cost more initially than a traditional system. According to the U.S. Department of Energy Efficiency and Renewable Energy, tankless water heaters are 24-35% more efficient that traditional water heaters. Keep in mind, too, that tankless systems last up to 20 years, nearly twice as long as tank hot water heaters.
