In 1986, I installed a 1.5-ton geothermal heat pump in my home using two 500-foot horizontal HDPE earth loops. After digging a trench, I connected the loops to the pump and opted for a 2 HP swimming pool pump to fill and flush the system, as a garden hose couldn't provide the needed flow rate.

Caleffi's new AutoFill has a fill rate of 5.5 GPM and maintains stable system pressure, ensuring consistent results without the need for constant monitoring.

Always assume the old boiler was installed wrong. This principle has served me well in my career by finding problems before we own the system.

In 2024, the North American air-to-water heat pump market saw significant expansion, with nine new offerings introduced at the January AHR show by companies new to this category. By year's end, at least 18 companies either have or plan to offer these pumps in the U.S. Read the list of these companies as of mid-2024.

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.

A western Wisconsin university chose a hydronic system with Uponor PP-RCT piping for their new sports complex to meet project scope, timelines, and space constraints.

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.

Keystone Air Power is a thriving Amish enterprise that runs a fully modern hardware store in Central Pennsylvania. The 52,000-square-foot building is constructed around a cutting-edge, off-grid mechanical and electrical system that demonstrates the Amish's knowledge of smart technology.
