2009 edition of code establishing a baseline for the design and installation of fuel gas systems and gas fired appliances through performance requirements.

Technical report describing how the FSEC Energy Research Center explores low-cost space-conditioning upgrades for existing homes by integrating centrally located, high-efficiency ductless mini split heat pumps with older but functional central space conditioning systems, aiming to achieve energy...

Webpage recognizing the most efficient products among those that are ENERGY STAR certified.

Article describing a study of the potential to use heat pumps to heat and cool homes across the United States, including cold climate locations like Alaska.

A ENERGY STAR guide on efficient heating, ventilation and cooling systems in residential homes.

Report describing the performance, economics, space heating impacts, and user satisfaction of heat pump water heaters (HPWHs) in the upper Midwest, based on a field study and survey of participants in the MECA HPWH incentive program.

Report describing the objective evaluation of space conditioning interactions between heat pump water heaters and home heating systems during winter 2016-2017, revealing a smaller than anticipated impact on space conditioning loads.

Study in which a central heat pump water heater system was monitored in detail and used to create a model for assessing similar systems in various climates.

This project analyzed combined condensing water heaters or boilers and hydronic air coils to provide high efficiency domestic hot water (DHW) and forced air space heating. Called "combi" systems, they provided similar space and water heating performance less expensively than installing two...
