Government planners, taking their queues from politicians and advocacy organizations, have steered the future of energy supply away from fossil fuels and toward renewably-sourced electricity. It’s happening on every level from the feds right down to local city councils.

Dan Holohan: Dry steam is the goal

Things to consider when replacing a steam boiler.

I love all the advances taking place in the world of hydronics, but I’m still seeing plenty of steam systems out there in our older cities, so knowing about dry steam will help you if you’re replacing a steam boiler. The dryer the steam is, the better you’re going to look to your customers.

Many legacy hydronic heating systems use a fossil fuel boiler to supply fin-tube baseboard heat emitters in some areas of a building and lower-temperature radiant panels in other areas.

Dan Holohan: That seventies show

Learn from the mistakes of the past or we’ll be doomed to repeat them.

I began my career in the HVAC business in 1970 as a truck driver for an AC/refrigeration wholesaler. I stayed there just six weeks because my father — who worked for a manufacturers’ rep — told me there was an opening for a clerk at the rep. It paid $110 a week, which was $10 more than I was getting driving the truck. Plus, I’d get to work with him as my boss.

Dan Holohan: The geography of auto-feeders on steam

Auto-feeders — yay or nay?

I have heating (plumbing, fire suppression, etc.) shops in New York and New Jersey. This is very much steam country, and we repair and replace steam boilers and systems all week long and have been for decades.

One Comment

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.

 All boilers that burn hydrocarbon fuels such as natural gas, propane, oil or wood produce water vapor as a byproduct of combustion.

I’ve written it before and I’ll write it again — panel radiators are one of my favorite hydronic heat emitters. I base this sentiment on several benefits. Here are a few to consider…
