Geothermal (a.k.a. ground-source) heat-pump systems continue to be a popular topic in HVAC discussions. Many state and federal agencies are now offering generous incentives for installation of geothermal heat pumps in both residential and commercial applications.

I recently helped install a closed-loop geothermal heat pump system for my daughter, her husband and their 1-year old son, Henry.

Brasscraft Mfg. Co. continues its legacy of innovation with an enhanced version of its patented Safety+Plus Excess Flow Valve (EFV).

The geothermal heat pump market is headed for another strong year in 2019. The 30% uncapped federal income tax credit on EnergyStar-rated geothermal heat pumps remains in full effect.

Over the last few months, I’ve had several inquiries from people eager to get into the hydronics industry.

Many renewable energy systems have thermal storage tanks that bridge the gap between when energy is available from the heating source, and when that energy is needed by a heating load.

The educational event runs from 7:30 a.m. to 5 p.m. May 22 at Landmark College in Putney, Vermont.

When most people think about solar, they think about photovoltaic panels that generate electricity, but they don’t often think about solar thermal. When considering heating water, solar thermal is incredibly efficient by comparison.

Last month, we began with a concept for an “ideal” thermal storage tank. This tank was then shown in both a classic four-pipe configuration, as well as a newer configuration called two-pipe.  This month, we’ll look at a morphing of these two piping methods to create a three-pipe configuration. We’ll also look at options for connecting multiple thermal storage tanks together.
