Why Go Tankless This Year?

electric demand water heatDallas Tankless Water Heaters is in the know about what can save you money in your home, business, or commercial facility. Tankless Water Heaters are also known as demand-type or instantaneous water heaters, and this new technology can save you money because it provides hot water only as it is needed. The reason is a tankless water heater does not produce the standby energy losses associated with storage type water heaters. These losses are where your costs have increased because of the energy it takes to keep all that extra water inside the water heater hot.

At Energy.gov, you can find the basic information you need regarding today's technology behind installing a new tankless water heater systems. If you are interested in the basic information about how they work, whether a tankless water heater might be right for your home, and what criteria to use when selecting the right model; then we encourage you to take a look at the rest of this article. Check out the Energy Saver 101: Water Heating infographic to learn if a tankless water heater is right for you on the right side of this article.

How Tankless Water Heaters Work

Tankless water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. The end result is tankless water heaters deliver a constant supply of hot water. You will never have to wait for a storage tank to fill up with enough hot water. However, a tankless water heater's output does limit the flow rate.

Typically, tankless water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a tankless water heater to its limit. To overcome this problem, you can install two or more tankless water heaters, connected in parallel for simultaneous demands of hot water. You can also install separate tankless water heaters for appliances -- such as a clothes washer or dishwater -- that use a lot of hot water in your home. Long term, you will still be saving money as energy costs will definitel be less.

Other Ways To Use Demand Water Heaters:

  • Remote bathrooms or hot tubs
  • Booster for appliances, such as dishwashers or clothes washers
  • Booster for a solar water heating system
  • Remote outside kitchens
  • Remote outside showers
  • Laundry Rooms which have showers or steam equipment

Advantages and Disadvantages For Your Location:

If your home averages around 41 gallons or less of hot water daily, demand water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. They can be 8%–14% more energy efficient for homes that use a lot of hot water -- around 86 gallons per day. Statistics support even greater energy savings of 27%–50% if you install a demand water heater at each hot water outlet. ENERGY STAR estimates that a typical family can save $100 or more per year with an ENERGY STAR qualified tankless water heater.

The initial cost of a tankless water heater may be greater than that of a conventional storage water heater, but tankless water heaters will typically last longer and have lower operating and energy costs, which could offset its higher purchase price. Most tankless water heaters have a life expectancy of more than 20 years and this new technology in plumbing fixtures means easily replaceable parts that extend their life by many more years. In contrast, storage water heaters last 10–15 years.

Tankless water heaters can avoid the standby heat losses associated with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy if they have a constantly burning pilot light. This can sometimes offset the elimination of standby energy losses when compared to a storage water heater. In a gas-fired storage water heater, the pilot light heats the water in the tank so the energy isn't wasted.

The cost of operating a pilot light in a tankless water heater varies from model to model. Do the research and find out about various manufacturers how much gas the pilot light uses for the model you're considering. If you purchase a model that uses a standing pilot light, you can always turn it off when it's not in use to save energy. Also consider models that have an intermittent ignition device (IID) instead of a standing pilot light. This device resembles the spark ignition device on some gas kitchen ranges and ovens.

Before buying an on-demand water heater,  please consider the following:

  • Size
  • Fuel type and availability
  • Energy efficiency (energy factor)
  • Costs
  • Installation and Maintenance
  • Request cost estimates in writing from us
  • Ask for our references
  • Check out Dallas Tankless Water Heaters/Atlas Plumbing with your local Better Business Bureau
  • Dallas Tankless Water Heater will obtain a local permit if necessary and understands local building codes

Remember that periodic water heater maintenance can significantly extend your water heater's life and minimize loss of efficiency. Read your owner's manual for specific maintenance recommendations. If you are hoping to improve energy efficiency, after your demand water heater is properly installed and maintained, try some additional energy-saving strategies to help lower your water heating bills. Some energy-saving devices and systems are more cost-effective to install with the water heater.
