To be tankless or not to be tankless? That is the question.
Need to replace a water heater in your home? Or install one in a new house? If so, the full question you need to ask is:
“Should I buy a conventional water heater with a water storage tank based on very old technology (No.), or should I buy a tankless water heater based on the latest proven technology on the market?” (Yes.)
Like an elephant in the room (specifically, the bathroom, laundry room or kitchen), it is hard to ignore this issue, because the financial and environmental impact of the hot water your family consumes is so large.
Producing hot water accounts for almost 20% of your total home energy cost, second only to your HVAC expense. So, given that you will be living with the ramifications of your decision everyday for a decade or two, what factors should you consider about this big issue to determine the correct answer?
Consider this analogy: Generally, the purchase price of a hybrid or electric automobile will be higher than the price of a car in the same class that uses a gasoline-powered internal combustion engine – a technology from the mid-1800s.
Similarly, the upfront purchase cost of a tankless on-demand water heater will be more than a conventional water heater with a water storage tank – another technology from the 19th Century.
Because so many hybrid and electric cars are being sold these days, the up-front purchase price is obviously not the only issue that buyers consider. Energy efficiency and environmental impact are the two main concerns buyers of those vehicles consider.
Those same two concerns, energy efficiency and environmental impact, are the primary issues to consider when choosing your next water heater.
According to the U.S. Department of Energy, you should seriously consider installing a tankless water heater because:
The energy efficiency rating (EF) of a water heater is calculated according to how much hot water is generated by each unit of fuel consumed in the process. The EF rating scale is 0 to 1.00, with a 1.00 rating being the most efficient.
Currently, 0.66 is the highest EF rating for a conventional storage tank water heater, according to the Department of Energy on its water heater energy cost calculator web page.
The list of ENERGY STAR Certified Waters Heaters includes six models by Navien, the brand of on-demand water heaters we feature. Navien has 4 models with a near-perfect 0.99 EF. The other 2 Navien units on the list have a 0.97 EF rating. Not bad, right?
Obviously, highly-efficient tankless water heaters will have lower operating costs than lower-rated units. It is easy to imagine how much money you can save month after month, year after year, with a Navien tankless water heater that is 33% more efficient than even the highest-rated storage tank models.
According to eComfort.com, Navien is an environmentally-conscious company that has developed ECO Premixed burners for their tankless water heaters that significantly reduce the emission levels of carbon dioxide (CO2) and nitrous oxide (N2O) into the atmosphere, which is very beneficial to improving the environment.
