This is the third installment of the mini-series Why Radiant Heat Rocks!. In this series I’m highlighting some of the more unusual applications for which radiant heat excels over the more traditional hot-air approach to heating.

Wood Shingle Mill

We received a call one day wondering if we could help with a particular problem. A shingle mill had an issue on their production line. At a particular point in their process a worker had to manually handle blocks of wood, passing them repeatedly over a blade. In winter this job was particularly hazardous since the building was unheated and the blocks of wood came in from the storage yard frozen and covered with snow and ice. The worker’s fingers would quickly get numb from the cold and the handling of the frozen blocks. Gloves and similar methods didn’t work. Gloves reduced the worker’s ability to handle the lumber with dexterity, or would fetch up on the rough-sawn material. Blowing hot air into the area didn’t do it either. The hot air would just rise away, leaving the worker just as numb as if the hot air system wasn’t there.

The biggest concern was safety, though. Once the worker lost the required dexterity in his fingers he ran a very high risk of getting those fingers caught in the machinery. Whirling blades. Lost fingers. The mill rep painfully quipped that “there wasn’t a piano player in the plant”. Ouch.

Radiant Heat To The Rescue

Radiant heat warms object directly. It naturally travels from the warm source to the cold objects around it – which includes people, their arms, their hand and their fingers. So it was a simple matter of placing a few radiant heating panels directly above and below the workstation and controlling it with a simple switch. The radiant heat enveloped the worker in a curtain of warmth. The results were clearly outstanding. With sufficient radiant heat in place, the worker (and his fingers!) remained nimble throughout the shift and accidents dropped like a rock.

It was a simple and inexpensive solution that only radiant heat could have solved. And the town’s piano teacher is now back in business. :-)

Why Radiant Heat Rocks! (Part 4)

In Why Radiant Heat Rocks (Part I) of this mini-series of articles I said that I wanted to highlight some of the more unusual applications for radiant heat that I’ve encountered over the years. This particular one is non-traditional in that, while still a heating application, it’s not one intended for comfort or occupants.

An Interesting Paint Problem

A customer contacted me one day with an idea. Could radiant heat help him with his particular problem? He had a business where he contracted to the local electrical utility to service their boom and bucket trucks. You’ve seen the type – the type of service vehicle with a boom arm with a bucket on the end that a utility lineman uses to gain access to the power wires and transformers high up on poles.

Bucket Truck with Boom

The picture depicted here gives you an idea of what I mean.

It was his task to remove the boom and bucket and refinish the boom arm with a particular type of “paint”. I don’t know all of the details, however the paint is a special type of epoxy coating that is non-conductive, hardy and probably has several other properties I hadn’t been told about. The important part is to understand that this particular epoxy finish had to be heated to a specific temperature range in order to cure properly.

The old way he was doing it was to remove the boom, prepare the surface, and apply the coating. Then he had to raise the temperature of his shop to the desired temperature so that the epoxy finish could cure. As you can imagine, heating the entire volume of air was a rather expensive proposition to him. Furthermore, the elevated temperature made it too warm for any other work to be conducted in the shop while he waited for the coating to cure. Also, given all the convective currents caused by the hot air system, dust and other dirt was being circulated in the space and speckled his finish.

Since radiant heat warms objects directly instead of first heating the air, I knew we had a solution for him. The idea we came up with was to build a box large enough in which to place the boom arm. Then we embedded SmartRooms Radiant Ceiling Panels into the walls of the box and insulated the outside. This design focused the radiant heat onto the painted parts with minimal heat loss. A thermostat was added to automatically maintain the desired temperature.

The result of directly applying radiant heat to the epoxy finish was nothing short of outstanding – even for someone who’s come to expect such things. The epoxy finish was able to cure in record time. Instead of taking days to cure in a hot-air filled shop, the radiant heat did it in a few hours! Since only the boom arm was heated, he was able to drastically reduce his energy costs. With no circulating dust and other contaminates, the finish was the best he had ever produced. His customer was so pleased with the finish and the turn-around time, he was promised a lot more work in the future.

Radiant heat is a very versatile form of heating and has many natural benefits that are not immediately apparent when you’re only familiar with hot air systems. I hope this story, and the others in this series, will get you thinking about employing radiant heat to work for you. So challenge us with a project! I bet we can come up with a solution for you.
