TANKLESS WATER HEATER BENEFITS

Tankless Water Heater Bradford White

How Does A Tankless Water Heater Work?

We fill up big 40, 50, 75, 100 gallon water heater storage tanks, 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 an energy efficient tankless water heater, also called on-demand, instantaneous, continuous flow, inline, flash, or instant-on water heaters that  heat water immediately as it flows through the heater. No waiting for a tank to reheat more water, wasting time and energy. Watch video. Energy costs can be  $400-$600 each year to heat a standard hot water storage tank. Hot water energy bills are the 2nd largest expense behind heating and cooling costs.

On Demand Water Heater 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 heater can be 24%–34% more energy efficient than conventional storage tank water heaters.

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

All The Hot Water You Need. 

Tankless natural gas can provide hot water at a rate of 4 to over 6 gallons per minute. Electric tankless water heater can provide 2.5 GPM to 5 GPM of hot water flow. With a tankless you can heat only so much water at a time. If you need more hot water because you run the dishwasher, clothes washer and shower at the same time—water temperature will fluctuate.  If you have 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. Learn about a Navien tankless water heater.

How much hot water do you need at one time? Do you run 2 showers or maybe a shower and a couple sinks simultaneously? Here is hot water flow guide for various fixtures. 2.5 gpm for a shower and 1.0 gpm for a couple bathroom faucets is a good starting point.

FIXTURE AV. FLOW GPM AV. TEMP.
Tub Shower 2.5 – 3.0 GPM 104°F
Tub 4.0 GPM 102°F
Clothes Washer 2.0 GPM 120°F
Dishwasher 1.5 GPM 110°F
Kitchen Sink 1.5 GPM 110°F

Compact Sized Tankless Water Heater.  

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. Can provide hot water for homes, apartments, condominiums, townhomes, business.

Tankless Water Heater Is Safer.

You won’t spring a leak and cause a real mess like a tank water heater does. No harboring Legionella bacteria or carbon monoxide poisoning from poor exhaust. Worst case is an exploding or a burst water heater tank due to high pressures. If the temperature and pressure relief valve frequently opens or starts leaking, you likely have a pressure problem that deserves immediate attention. Tankless water heater air-supply and exhaust vents are sealed meaning poisonous carbon monoxide won’t enter your home due to backdrafting. No tank to store bacteria. No water pressure build up either, no tank.

Water Hardness.

Water Heater Flush

Hard water mineral scale reduces water heater, dishwasher, washing machine lifespan up to a third. Scale won’t be an issue if you already have whole-house water-softening. But if your water hardness exceeds 7 grains per gallon (Joliet area can be over 18 grains), 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 tankless unit 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 ten 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 Cost Installed and the Payback.  

Tankless Water Heater Install

A quality tank water heater install can be $1500 to over $3000 depending on size, efficiency and type. A whole home tankless investment can be less or more than $6,000 to disconnect old water heater and haul away, all new piping, drain, venting, equipment and installation. Given a tankless heater 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, long life, unlimited hot water, no costly tank leaks, 10 year warranty, and a tankless water heater makes economical and environmental sense.
