For Your Home

Water Heating

Today’s gas water heaters are more efficient than ever boasting a recovery rate twice as fast as that of electric water heaters at about half the cost.

The Basics
Tankless water heaters are instantaneous systems without storage containers. They heat water only as you use it. Designed for homes with limited space, only one or two occupants, and easily coordinated hot water requirements, a properly sized tankless water heating unit will provide an endless, energy-efficient supply of hot water.

How do they work?
A tankless water heater only works when there is a demand for hot water. The hot water tap operates like an ignition key, triggering the burners as cold water enters the heater. Water heats at a constant temperature as long as the tap is open. When the tap is turned off, the system shuts down.

Shopping Tips & Considerations

  • Decide if this type of heater will work for your home. A qualified HVAC Contractor will need to help you evaluate water usage and hot water flow requirements. Your house line must have adequate pressure to support a tankless water heater.  Please consult with your HVAC contractor and/or installer before purchasing.
  • Consider combustion air requirements. Because air is drawn from within the room where the water heater is installed, your installer may have to make special provisions.
  • Consider venting options. In general, vent length should be as short and straight as possible. Also, have your HVAC Contractor make certain your gas line is sized properly.
  • Compare products, get several purchase and installation quotes, and choose a qualified HVAC contractor. Also consider installation and maintenance costs.
  • Compare installation and repair warranties. Even though today's models are designed to last for 20 years, you should check maintenance requirements and service support availability.
  • Look for design certified models tested to national standards by a nationally recognized laboratory.
