Did you know... Water heating represents the second largest consumption of energy in the home after heating and cooling!

With fuel costs rising, choosing a hot water heater that will reduce your future energy consumption is one of the smartest investments you can make! Hybrid Electric models for instance, are the most efficient water heaters available – some with up to $4,000 in lifetime savings and less than 2 year payback!

Did you know... The average life expectancy of a water heater is only about 8 to 12 years. And when it fails, it can leave a mess!

Don’t flood your basement or your home! All water heaters leak, eventually. It's a fact! If your water heater is over 10 years old, be proactive and replace it with a new water heater before it fails!

Conventional Water Heaters:

Conventional water heaters

Conventional storage water heaters remain the most popular type of water heating system for homes and buildings. This is mostly due to price and familiarity. Storage water heaters operate by releasing hot water from the top of the tank when you start to use hot water. To replace the hot water, cold water enters the bottom of the tank, ensuring that the tank is always full. Residential water heaters typically store 40 to 80 gallons of hot water.

Because water is constantly heated in the tank, energy can be wasted - even when you're not using hot water. This is called "standby heat loss", thus costing you more money to operate. Only tankless water heaters avoid standby heat loss. However, some conventional water heater models have heavily insulated tanks, which significantly reduce standby heat loss.

Tankless Water Heaters:

Tankless gas water heaters are today's most popular "green" hot water solution. No matter how many body sprays and showerheads, no matter how deep the whirlpool, you will not run out of hot water with a properly sized tankless water heating system.

Tankless gas water heaters are more energy-efficient than conventional tank heaters, because they eliminate the need to maintain a large supply of pre-heated water. Tankless units provide hot water on-demand at a precise temperature needed, so there is no storage and therefore no need to expend energy heating that stored water.

About the size of a medicine cabinet, tankless water heaters can easily be mounted to the wall. Convenient digital controls make it easy to adjust the temperature - for convenience as well as safety.

How they work...

  • A hot water tap is opened.
  • The opened tap allows water to flow through the water heater. An internal water flow sensor detects this flow.
  • Upon flow detection, the flow sensor sends the activation signal to the computer board.
  • The computer automatically ignites the burner.
  • As water flows through the heat exchanger, it absorbs heat from the burner.
  • By the time the water exits the heater, it has reached the designated set temperature.
  • When the hot water tap is closed, the water heater automatically turns off.

Hybrid Heat Pump Water Heaters:

Hybrid Heat Pump Hot Water Heaters

A hybrid heat pump water heater gives you the same reliable hot water as a standard electric water heater — only it uses less than half as much energy. And it can save you money by lowering electric water heating costs by up to 60%, and reliably continuing those savings year in and year out. You may even qualify for utility rebates and tax credits that make a heat pump water heater even more affordable.

How they work...

To understand the concept of a heat pump water heater, imagine a refrigerator working in reverse. While a refrigerator removes heat from an enclosed box and expels that heat to the surrounding air, a heat pump water heater takes the heat from surrounding air and transfers it to water in an enclosed tank.

During periods of high hot water demand, hybrid heat pump water heaters switch to standard electric heat automatically (hence “hybrid” hot water heaters). They come with a control panel that you to select from different operating modes, which include:

  • Efficiency/Economy – Maximizes energy efficiency and savings by only using the heat pump to heat water.
  • Auto/Hybrid – The default setting is ideal for daily use, providing energy-efficient water heating with sustained heat.
  • Electric/Heater – This high-demand setting is the least energy-efficient, using only the electric element to heat water.
  • Vacation & Timer (not available on all models) – Saves on energy when you are away from home by placing the unit in "sleep" mode until you return.
