NPC invites onbalance to settle debate

Unless you’ve been living under a rock, you are probably aware of the decade’s long debate between the National Plasterers Council and the consulting group, onBalance, concerning defective plasters surfaces.

The two groups, who represent the interests of plasterers and pool service professionals respectively, seem to disagree about everything.

Now, a challenge has been presented to settle the dispute "in the pool,"

Pool Industry Expo 2014, Sept. 25-27, Monterey, Calif.

Beautiful Monterey is once again calling.

The West Coast industry’s annual education vacation — Pool Industry Expo — is scheduled for Thursday, Friday and Saturday, Sept. 25-27, at the Monterey Conference Center.

The pristine setting and resort heaven along the Northern California coast is one great reason to make this service show a must-see destination for professionals winding down after a busy summer schedule. Yearly attenders know that few venues can match the quality and variety of environment, scenery, recreation, entertainment, lodging and dining that you'll find in Monterey.

But add to that the opportunity to learn pool and spa service and repair tricks aplenty in just three days and it’s little wonder that P.I.E. has a 28-year history of success.

While the seminar schedule offers 96 hours of educational and hands-on training, all specifically tailored to the needs of the service professional.

In addition to classroom training, the show features exhibits from leading manufacturers and suppliers to the Northern California pool and spa service market and the opportunity to talk shop with a number of experts in the field.

While touring the exhibits, show-goers will find hundreds of manufacturer-sponsored promotional giveaways, and show organizers will once again offer a drawing for a total of $2,000 in cash prizes and a one-week Hawaiian vacation for two.

The host hotel for the event is the Marriott Monterey, connected to the Monterey Conference Center, where the exhibits will be on display. Both are located in the heart of historic downtown and just steps away from the Monterey Peninsula. A special group rate of $194 per night plus tax for a deluxe single or double room is available.  Reservations can be made online at

A number of other hotel and motel accommodations are available at varying prices, many within walking distance of the Monterey Conference Center.

Pool heaters: What would we do without them?

By Marcelle Dibrell

Water temperature is perhaps the most critical parameter for bather comfort in a swimming pool

A change of only a few degrees is significant for swimmers, and makes a difference in whether the water is inviting.

The reason that water temperature is so crucial is because body heat is lost much faster in water than it is in air of the same temperature. Because water has a much higher thermal conductivity, combined with the fact that it is denser than air, by some estimates, a body in water can lose heat up to 200 times faster than in air.

Furthermore, optimal temperatures range not only from person to person, but are also dependent on pool use. Different activities change the optimal water temperature.

For example, competitive swimmers prefer, on average, water temperatures between 79° to 81°F. Younger swimmers tend to want the water a little warmer while senior citizens want it warmer yet — at around 88°F.

Pool heaters also extend the swimming season. For thousands of pool owners in the country, September marks the beginning of the end of the swim season

For some pool owners, the swimming season can be doubled with the simple addition of a heater. 

It is for these reasons that heaters are one of the most important additions to a pool. And for spas, of course, the heater is the most important component.

Pool heaters are sized to raise the temperature of a given volume of water from 20°F to 40°F. Generally the rise in temperature should be gradual — about 1°F per hour. 

Correctly sizing the heater is essential to its performance. If the heater is too small, it will heat the water too slowly. On the other hand, if the heater is too big, it may take up too much space on the equipment pad and the operational costs will increase

Like the pool itself, a heater is a luxuryHaving a constant and reliable water temperature comes at a cost, and depends on the type of fuel employed.

There are advantages and disadvantage to each type of heating device. All of the choices — including gas, electric, heat pumps and solar panels — will extend the swimming season and make water comfortable

The following articles contain basic information that service technicians may need when dealing with pool heaters.
