Tankless Water Heaters

Tankless water heaters, also called demand or instantaneous water heaters, heat water on demand without the use of traditional storage tanks. Tank water heaters generate standby heat losses by keeping storage tanks full of hot water, even when hot water is not required. Devoid of storage tanks, tankless water heaters supply hot water only when needed and thereby cut the standby energy losses associated with traditional storage tanks.

How a Tankless Water Heater Works

Tankless Water Heater DiagramWhen an electric or gas tankless water heater is fed with cold water, a flow activated switch turns on a heat exchanger responsible for heating up the water to desired temperature. Electric resistance heating coils function as heat exchangers in electric units while gas fired burners using natural gas or propane are heat exchangers for tankless gas heaters.

Energy Efficiency Maximization

Sizing and installation are key requirements in optimizing the energy efficiency of your tankless water heater. For this reason it is highly recommended to let professional plumbers handle the installation work on your behalf, even if you are a do-it-yourself fan.

For proper sizing the following variables need to be factored in:

The above factors will determine the correct type of tankless water heater suited to your home.

Types of Tankless Water Heaters

Electric or gas tankless units come in two main types: Point Of Use(POU) or Whole House.

POU Water Heaters
These units can be installed throughout the household at various points of use such as under kitchen sinks, bathroom faucets and showers. POU tankless units are dedicated use heaters and therefore supply hot water to a single fixture at a time.

Whole House Water Heaters
Whole house units have a higher GPM flow rate and therefore the capacity to serve more than one fixture at a time for simultaneous demands of hot water. The flow rate will determine the size and number of whole house heaters for your property.

Gas versus Electrical Tankless Units

Gas Electrical
Installation Costs Special venting requirements push up installation costs and may prolong return on investment period Cheaper than gas due to no venting requirements
Operating Costs Unstable operating costs as gas rates are predicated to rise drastically in the future Already cheaper to run than propane gas in many areas - electricity costs are considered more stable and are expected to increase in a much slower rate than future gas prices
Flow Rates As much as 8 GPM or even higher in warm climates
  • Between 3-3.5 GPM during winter in cold climates
  • As much as 8 GPM in warm climates
Venting required no venting required
Maintenance Yearly maintenance no maintenance
Environmental Impact
  • Greenhouse gas emissions
  • Fossil fuel reliance
  • no greenhouse gas emissions
  • future electricity to come from a range of green sources like wind, wave energy and solar

Despite having high installation costs, properly sized and professionally installed tankless water heaters will provide households with long term energy saving and unlimited supply of hot water on demand.
