Tankless Water Heater Benefits

What To Know Before Investing In A Tankless Water Heater.

We fill up big 40, 50, 75, 100 gallon water heater storage tank, then pour energy into them 24/7 to make sure we have hot water when wanted, at least if we don’t empty the tank with long showers or baths. Not true with a energy efficient instantaneous tankless water heater. No waiting for a tank to reheat more water, wasting time and energy. Watch video.

You spend $400-$600 each year to heat a standard hot water storage tank. That’s the 2nd largest expense of 14-18% from your energy bills.

Green Energy Savings

Energy.gov reports homes that use 41 gallons or less of hot water daily (a typical shower uses about 10 gallons of hot water), a demand tankless water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters.

Tankless can be 8%–14% more energy efficient for homes that use a lot of hot water — around 86 gallons per day. You can achieve even greater energy savings of 27%–50% if you install a tankless demand water heater at each hot water outlet.

Nagging worries remain with your existing tank water heater:

All The Hot Water You Need, As Long As You Need It. 

Tankless water heaters can provide hot water at a rate of 2–5 gallons per minute. Gas-fired tankless water heaters produce higher flow rates than electric tankless water heater. And if you need hot water for simultaneous, multiple uses in large households or commercial use you can install two or more tankless water heaters, connected in parallel for simultaneous demands of hot water.

Tank water heaters have grown bigger as federal regulations now require thicker insulation to reduce standby heat loss. Tankless gas water heaters are about the size of a suitcase and hang on the wall.

Tankless Water Heater Is Safer

Tankless water heater won’t spring a leak and cause a real mess like a tank water heater does, or harbor Legionella bacteria. Air-supply and exhaust vents are sealed meaning poisonous carbon monoxide won’t enter your home due to backdrafting.

Water Hardness

Nothing reduces water heater efficiency and life more than hard water mineral scale. Scale won’t be an issue if you already have whole-house water-softening. But if your water hardness exceeds 7 grains per gallon, then it’s worth investing in a treatment system like a softener, filter or a point-of-use cartridge water conditioner to alter hardness. If not then every year or so (or 500 hours of use) the system should be maintained to remove scale build up on expensive heating components.

Electric Tankless Water Heater

One drawback to electric tankless water heater units is the output, which tops out at 36 kilowatts, or about 123,000 Btus. Electric tankless heats water with thick copper rods, are quieter and about a third smaller than gas units. And because they don’t need vents, they can be installed almost anywhere, including under sinks and in small closets. Electric water heaters last half as long as gas units: Typical warranties are three to five years.

Wi-Fi Option

Adjust the temperature and monitor gas and hot-water usage on your phone and identify the source of a problem.

Vacation Easy 

Vacation time? No worry of an expensive tank leak. Takes a few seconds to drain; then turn gas or electric off.

Tankless water heater payback.  

A quality tank water heater install can be $1000 to $3000 depending on size, efficiency and type. A whole home tankless investment can be $4,000 to $6,000. Given tankless can last 2 or 3 times longer and lower utility bills around 20% a year, the higher upfront costs makes sense. Add space saving design, unlimited hot water, no costly tank leaks and a tankless water heater makes economical and environmental sense.
