Tankless Water Heaters FAQs Be Green. Live Better!

Windows FAQs

  • Q:What is a tankless water heater?

    A:Tankless water heaters raise cold water to the temperature you’ve digitally set when your demand for water passes either a gas burner or electric element. Another way to look at it is if a conventional tank-style water heater stores hot water and heats it 24/7, whether you use it or not, a compact Tankless water heater only heats water on demand, making it more energy efficient.

  • Q:What are the benefits of a tankless water heater and how does it differ from a traditional unit?

    A:A tankless water heater has lower operating costs, uses less space and can reduce energy consumption by as much as 30-50%. It also can provide continuous hot water at a precise temperature. However, it does require more up-front investment, may need venting, and takes about 13-15 seconds longer to deliver water to the faucet.

  • Q:How much more do tankless water heaters cost to purchase?

    A:Generally, a tankless water heater will cost about 2 to 2-1/2 times as much as a standard water heater to purchase and install. Factored into that price are the higher production costs for the unit, venting, gas line resizing required to support the unit’s demands, and an electrical outlet to power it. However, you’ll have lower operating costs, more useable square footage and may be eligible for federal or local tax incentives and credits.

  • Q:Can a tankless unit be installed in the same place as my old water heater?

    A:As long as enough combustion air is provided, tankless water heaters can be installed in a utility room, garage, basement, attic, or placed on an outside wall. Plus, they may be installed in locations where a storage water heater may not fit. The digital temperature controller may be mounted in any room.

  • Q:How much may I expect to save on my monthly bill if I install a tankless water heater?

    A:Test results have shown that a tankless gas water heater costs about 30-50% less to operate than an electric water heater and about 20-40% less than a natural gas water heater. Please note that there is no guarantee that you will achieve these exact cost savings as many factors go into the efficiency and operation of these units.

  • Q:Do tankless water heaters have lower operating costs?

    A:The operating cost of the unit depends heavily on your usage and behavior. Tankless units carry a much higher Energy Factor, meaning a larger percentage of the energy you use will be directly transferred to heating your water. A tankless water heater has no standing pilot light, no standby loss and burners that modulate to maintain maximum efficiency. So if you have exactly the same water usage behavior (duration of shower, amount of applications using the unit, usage at the same time of day) a Tankless will have a lower operating cost.

  • Q:Can I install a tankless water heater myself?

    A:It is recommended that you use a licensed, professional installer as the installation of a water heater deals with carbon monoxide, natural gas, water lines, electrical components, and a high temperature heat-exchanger. Any one of these factors could cause catastrophic damage and/or injury if the unit is not installed properly. Be sure to use a trained professional who knows the necessary codes and safety factors.

  • Q:How do I ensure that I select the right-sized tankless water heater for my home?

    A:We will guide you through the selection process and ensure that the tankless unit you select will appropriately support your needs.

  • Q:Can I convert the water heater from liquid propane to natural gas or natural gas to liquid propane?

    A:No, these units cannot be converted from one fuel source to another.

  • Q:Where in my home can I install a tankless water heater?

    A:Depending on the model, a tankless water heater may be installed in all locations. However, any location will require access for combustion air from outdoors. Such models are not designed for use in mobile homes. Outdoor models are a great alternative if your climate is appropriate, saving both space and the cost of venting.
