Operators must push through challenges when retrofitting existing buildings to reap the benefits of high-efficiency heating ...

Energy stored in thermochemical materials can effectively heat indoor spaces, particularly in humid regions, according to researchers. Energy stored in thermochemical materials can effectively heat ...

The building heating load constantly fluctuates depending not only on weather conditions but also the facility’s occupancy rate and internal gains. This often results in oversized boilers that rarely ...

Condensing boilers, while commonly installed for heating hot water applications, often fail to deliver their inherent efficiency advantage because of deficiencies in the system design, start-up, and ...

Scientists have analyzed the performances of two air-source heat pumps in two small office buildings in China during the heating season. They identified the instantaneous load of the building as a ...

New research shows that hybrid heat pumps combining an electric heat pump and a gas boiler represent a technically feasible and economically viable solution to partially decarbonize heat supply in ...

Underestimating thermal bridging can greatly undermine a building’s performance contributing to heating load variances of up to 30% and cooling load variances of up to 200%, says the MMM Group. That ...

Load-based testing for heat pumps is an emerging experimental methodology designed to capture realistic, dynamic equipment performance by allowing the system to operate under its native ...
