Radiant & Hydronics Columns

My neighbor, Tony, loves his house. We live in a low-crime neighborhood on Long Island but Tony is always on guard against miscreants. He has a Ring camera on every side of his house, mounted high so they’re protected from spray paint. Some of the cameras turn on klieg lights and alarms if I step outside at night to toss the trash in the can. 

Over the last few years, I’ve written several columns describing how air-to-water heat pumps can provide heating, cooling and domestic hot water for homes. Many of the systems involve buffer tanks to help stabilize heat transfer from the heat pump to a zoned distribution system.

Aside from the fact that they are all used in hydronic heating systems, what do the following items have in common?

Frozen steam coils always seem to happen at the worst of times, don’t they? You’re busy because it’s cold enough to freeze coils. The place with the frozen coil contains people who are doing things that are so important they can’t possibly be without that particular coil. Not even for a minute. They’re on the phone, and they’re not being reasonable.

As interest and incentives build to transition space heating and domestic water heating systems away from fossil fuels and toward electricity, a somewhat predictable but only marginally quantified problem is developing. Two words describe it: Peak demand.

On the older hydronic systems, replacing the existing boiler with a new one was pretty straightforward. The installer connected the new boiler to the existing flue, piping and electric. The newer high-efficiency boilers are much different and require some additional planning.

A homeowner posted a question on The Wall at HeatingHelp.com about a drumroll sound that was coming from his brand-new steam boiler. What could it be? He included a video so all could hear, and sure enough, it sounded like a snare drum.

How’s that for a title? I’ll give you the answer right up front: Everyone!  And the best part is you don’t have to know what you’re doing; you just have to show up.
