Gas water heaters in many homes have low efficiency and use natural draft exhaust with the potential to back draft or spill combustion gases. High-efficiency gas tankless water heaters eliminate heat loss from stored hot water in tank systems, use more efficient burners, have ducted supply and exhaust air that cannot backdraft combustion gases, and can provide an endless supply of hot water. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings and safety benefits possible from a quality installed gas tankless water heater.

Many homes are missing whole-house fresh air systems that ensure adequate dilution of moisture, dust, pollen, and particulates inside the home. These contaminants can trigger asthma and allergy attacks as well as other health problems. Balanced heat recovery ventilation (HRV) and enthalpy recovery ventilation (ERV) provide an equal amount of supply and exhaust air adequate for effective dilution of contaminants. HRV’s include a heat exchanger to capture heat from exhaust air in the winter and supply air in summer for added efficiency. ERV’s also help remove unwanted outdoor moisture in summer and retain desired indoor moisture in winter for added comfort. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant health and enhanced comfort benefits possible from a quality installed balanced HRV/ERV fresh air system.

Many homes have vented attics that get very hot in summer and cold in winter. Converting an attic from vented to an unvented provides an opportunity to create a temperate space for heating and cooling equipment located there to operate more efficiently while also reducing infiltration of moisture, dust, pollen and pests year-round. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings, enhanced comfort, and health benefits possible from a quality installed unvented attic.

Where homes have crawl spaces, they are commonly unvented allowing excessive heat in summer, cold in winter, and humidity year-round. Converting a crawl space from vented to unvented provides an opportunity to create a temperate space for heating and cooling equipment located there to operate more efficiently while also reducing the infiltration of moisture, dust, pollen, pests, and soil gases year-round. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings, enhanced comfort, and health benefits possible from a quality installed unvented crawl space.

Installed correctly, energy-efficient replacement windows can reduce utility costs while improving comfort and durability.

Installed correctly, comprehensive vented-to-unvented attic upgrades can significantly reduce utility costs while improving comfort, indoor air quality, and durability of the attic structure.

Installed correctly, comprehensive vented attic upgrades can significantly reduce utility costs while improving comfort, indoor air quality, and durability of the attic structure.
