Water heating

  1. Electric Resistance Tank Water Heaters

    Despite being expensive to operate, many facilities install electric water heaters for their low initial costs and ease of installation. Find out what energy-efficient measures and alternatives are available to help mitigate the high costs associated with electric water heating.

  2. Gas-Fired Tank Water Heaters

    On a life-cycle basis, gas-fired tank water heaters are typically the least expensive means of heating water. Learn more about the different options available, and find out how to reduce energy use and maximize cost-effectiveness when considering a new or retrofit purchase.

  3. Heat Pump Water Heaters

    By pulling heat from the surrounding air, heat pump water heaters can more than halve your water heating costs. This article explains what you need to know about this energy-efficient technology and how to make the best choice when considering a new purchase.

  4. Small Gas Boilers

    Residential boilers offer commercial building owners comparable efficiency at a lower cost than commercial boilers, and their relatively small size makes it easy to move them in and out of buildings. Find out whether a residential boiler is right for your building.

  5. Tankless Water Heaters

    Tankless water heaters provide hot water without using a storage tank, resulting in higher efficiencies, smaller footprints, and higher life expectancies. Learn more about the benefits and drawbacks of this approach to water heating, and see if it makes sense for your building.
