Last month, we discussed direct-to-load hydronic heat pump systems. These systems use a variable-speed compressor and circulator to adjust heat output and flow, eliminating the need for a buffer tank or hydraulic separator.

GSHP systems have one primary significant difference: the outdoor refrigerant coil and fan are absent. Instead of these components, the functions of the outdoor condenser have been integrated into the indoor unit, resulting in a hybrid condenser and evaporator unit.

When only the air handler is operating the heat pump is able to supply the 120 ºF water. However, when the floor heating zone and the air handler are operating at the same time and the outdoor air temperature is below 24 ºF the fluid temperature leaving the heat pump can’t climb above 103 ºF. Why is this happening, and what can be done?

In the world of service contractors — where time, labor and oftentimes materials — are in limited supply, establishing a brand and marketing strategy aren’t always top of mind. For Texas-based plumbing contractor, Plumbing Outfitters, undergoing a rebrand was about much more than portraying an image.

The availability of heat pumps allows designers and installers of hydronic heating to include cooling.

Small businesses can attract new talent by allowing employees to share in the company's success. Offering phantom stock and profit-sharing can help employees feel valued and invested, moving beyond just earning a paycheck.

This article revisits smart plumbing systems and the need for our industry to adopt monitoring and automation strategies like those in HVAC for improved efficiency. At the recent ASPE Convention in Columbus, OH, I discussed how integrating intelligence into plumbing can significantly enhance building occupant safety.
