Here’s a countdown of the top 10 articles you read the most in 2021 based on the number of unique pageviews on www.pmmag.com. 

Whether driven by rigorous state and local regulatory mandates, or simply the desire to live more sustainably, the demand for a smaller carbon footprint and greater energy efficiency is growing in both the residential and commercial building and renovation markets.

This is very much steam country, and we repair and replace steam boilers and systems all week long and have been for decades. All that is fine, but what I find incredibly odd is the polarized perception of the automatic water feeder.

Water-to-water heat pumps, supplied from geothermal earth loops, represent a growing sector of the hydronic heat source market. Most current-generation models can produce water temperatures up to about 125° F, perhaps a little higher if you’re willing to push the compressor operating envelope.

Most hydronic systems have the boiler running up to 180° F with water returning from the system at 160°. This rarely happens in real life, but it’s the traditional way we do things.
