Air-to-water heat pumps and water-to-water geothermal heat pumps provide warm water for space heating, domestic water heating, and chilled water for cooling. Switching a hydronic heat pump system from space heating to cooling and vice versa seasonally is relatively simple. The system operating mode is changed at the thermostat or a dedicated system mode switch with heat, off, and cool settings.

I attended a conference hosted by the Building Performance Association and presented on air-to-water heat pump systems. Many professionals were interested in heat pumps, especially ductless air-to-air systems. One person mentioned the difficulty of finding qualified installers for air-to-water heat pumps and noted the higher cost compared to ductless air-to-air systems.

Flow direction is crucial in hydronic systems. Most designs have a fixed flow direction, but there are situations where reversals can occur. It's important to address these proactively to ensure smooth operations.

Primary/secondary piping is a way to achieve hydraulic separation by connecting multiple hydronic circuits with their own circulators to prevent interference. Using a pair of closely spaced tees is a common method to achieve this.

The NFB-C is available in two sizes: NFB-301C (301 MBH) and NFB-399C (399 MBH).

In rural upstate New York, residents harvest trees for firewood using chainsaws and hydraulic splitters. I burn about two face cords annually in my wood stove, enjoying its warmth during winter and relying on it during power outages caused by outdated utility lines.

With the world's focus on sustainability growing, plumbing engineers play a crucial role in adopting eco-friendly solutions. A major trend in commercial pump technology is the drive for efficiency and energy conservation. Find out how manufacturers are addressing environmental concerns and high energy costs.

I’ve written many PM columns discussing how air-to-water and geothermal water-to-water heat pumps can be combined with hydronic delivery systems to deliver efficiency AND superior comfort. This combination is a great solution for many consumers.

Learn more about the Hutterites, a branch of Anabaptists who live in colonies and operate large-scale farming operations in Western Canada and the upper Great Plains of the United States. Read on to discover some key differences between Hutterites and other similar groups such as the Amish and Mennonites.

In the 1980s, defective parts were occasionally received in the heating industry. Warranty issues were not too common back then and problems were quickly resolved by dealing with the supply house. No questions or paperwork were needed.
