Types of Water Heaters

You'll find two basic types of water heaters: storage and tankless. There are a wide variety of storage systems on the market, from heat pump products to solar thermal systems. On-demand (or instantaneous) units generate hot water on an as-needed basis. This is the most efficient tankless option, avoiding heat loss associated with hot water tanks. Geothermal or ground-source heat pumps and solar hot water heaters are the most efficient of all (but quite expensive). Electric heat pump water heaters typically offer the best balance of up-front cost, ease of installation, and savings over time.

  • Lower your water heating expenses by up to 50% or more
  • Models with a high energy factor save the most over time
  • Factor in installation costs when comparing systems

Heat Pump Water Heaters

Electric heat pump water heaters typically offer the best balance of up-front cost, ease of installation, and savings over time. They are a highly efficient way to heat water, using electricity to pull heat from the surrounding air and transfer it to water enclosed in the tank. Proper installation and maintenance are essential to optimizing the efficiency of your heat pump water heater.

Water Heater Fuels

In Vermont you can find water heaters fueled by electricity, propane, natural gas, solar power, wood, and heating oil. Fuel switching is possible and sometimes advisable if you can switch from an oil system to an efficient gas or heat pump system. Today’s electric-powered heat pump water heaters are highly efficient, relatively affordable, and don’t require venting. (They do, however, produce condensate, which has to be pumped or gravity-piped into a drain.)

How to Choose a Water Heater

Whatever your fuel type, the key is to choose a water heater with a high energy factor. (This calculates total efficiency, including tank insulation and standby heat loss.) There are a wide variety of water heater systems on the market, each with its own pros and cons. View a comparison from the US Department of Energy or contact us for help on how to get started.
