drops below a certain point, and install another heater to provide the extra heat needed to carry the full melting load.

In addition, snow melting systems require some means of circulating the heating solution through the pipes. When the area to be heated has a natural slope and the pipe run is short, it may be possible to use a so-called uthermal syphonfi Ideal conditions are seldom met, hOWever, and the safest procedure is to use a pump for circulation.

Most systems are turned on manually, by means of an on-off switch, the only other control being an aquastat to prevent overheating of the circulating medium. It is possible, however, to install more complicated controls, including one that will turn your system on whenever the temperature drops below

a certain predetermined point.


What does it cost to install a snow melting system? Naturally, the answer to this question depends on a lot of factors, among them the skill of the contractor who is to make the installation. Typical small-area installations, such as would be required for all but the largest theatre sidewalks, were studied for the period 1947-49 and it was found that costs ranged from $1.00 to $1.80 per square foot of area to bc

melted. The best way to find out what such a system would cost you, however, is to call in a heating contractor and ask him to submit an estimate.


What are some of the advantages of a snow melting system? Here are the ones most frequently reported by those who own them:

1. It is automatic. Once the switch is turned on, there is nothing more to do but sit back and watch the snow melt on your sidewalk, even while it is piling up on the sidewalks of other buildings all around yours.

2. It relieves your mind of the worry of liability because of injuries to passersby and patrons. When your system is set to begin operation by automatic control, it makes certain your sidewalk will never be covered with snow or icee even if bad weather comes overnight.

3. It cuts down cleaning costs in the interior of your building. Customers stamp their feet dry on the clear sidewalk before entering.

4. It has publicity value. If you contact the newspapers at the time when your system is being installed, and again when it operated during the first snow following installation, you stand a good chance of reaping publicity benefits. Snow melting is still news.

The System in Operation

The first recorded installations of snow melting systems for theatres were made by Edward J. Modie for his two theatres in Barnesville, Ohio. Before the installation, Modie used to have to keep a crew

of ushers with mops in the lobbies to clean up slush and water tracked in by patrons.

The first thing he did was to have the existing sidewalk torn up in front of his two theatres, which are on the same street near each other. Then coils of wrought iron pipe were positioned so that they would rest two and one-half inches from. the finished surface. The coils were connected to an automatic gas water heater in the basement of the theatre, and a new sidewalk was poured, embedding the pipes.

Water temperature in the supply main is held at 95-100 degrees F. The system is kept in continuous operation in winter, and Modie reports that his sidewalk becomes dry rapidly after a rainfall.

The management of the Covedale, Cincinnati, notes two outstanding advantages achieved by their snow melting system: good will and cleanliness. In regard to the latter, they state that wear on the theatres expensive carpeting is greatly reduced.

The Covedale installation is similar to the tw0 in Barnesville. Nearly a thousand feet of wrought iron pipe, welded together in a grid, are embedded in the concrete sidewalk. Antifreeze is used to protect the system when it is not in operation.

Concealed snow melting is gaining in acceptance for commercial establishr ments, industrial driveway and loading platforms, office buildings and the like. It seems probable that it will find increasing favor among theatre owners, who have always led the way in providing patron convenience.
