SOLAR SWIMMING POOL HEATING

Solar swimming pool heating is done with one of the two types of collectors you see in the

two photos above. For simple shingle roofs or rack mounts often the preferred choice is semi

rigid polypropylene grid style panels like our Powerpro shown in the photo on the left. Click

that photo for more. On the right is Powerstrip. We manufacture this product. It is fleible and

it can be made in any si!e. "his type of system is used when free!ing is an issue #low pitch

roof in an area where free!ing can occur$ % when systems need to be glued down as in the case

of a tile roof and when it is desired that the system be custom fitted to the roof or ground

space. Click that photo for more.

pool&s filter through hundreds of feet of pipe

and hundreds of s'uare feet of thin black solar

What Will a Solar Heater Do For My Pool?

"hrough etensive collaboration with universities and gov&t we&ve learned to simulate the

performance of a solar pool heater with remarkable accuracy. We&ve verified these curves

repeatedly with real systems and found ecellent correlation. 0elow is is a typical pool in San

*iego C, with a little pool shade% located near the ocean where the collectors are on a south

facing roof.

1223 solar means a solar heater si!ed at 1223 #same si!e$ as the top surface of the pool. We

also have compiled curves for many maor cities in the 4S. 5oherefor performance

predictions more specific to your location and for a full discussion on si!ing a solar heating

system for a pool.

skilled contractors that implement these systems have devised their own proprietary schemes

for attaching these systems to all the various roof types. Our Powerpro collector is the best

polypropylene collector we can get our hands on. We supply it with the best mounting

hardware for your uni'ue situation including options like etra rows of stainless steel plastic

coated strap for high wind areas. Our no roof penetration schemes for tile roofs warrant your

attention. See Powerprofor more on this collector type.

Fleible collectors are assembled from a header pipe and a tubing strip. "he fleibility allows

use right on a flat roof in a free!ing climate. It also allows us to glue it directly to wavy s-tile

roofs so very common in the big solar markets of the 4S. We&re also able to fit these systems

where regular Powerpro types can&t make full use of available space. SeePowerstripfor more

on this collector type.

aging etc all in combination with stress from pressure in the water. "ake away the pressure

Often solar pool heaters go on the roof of the house. We are often asked to re and re solar

heaters for re-roofing and we discover that the reason the roof is leaking is a poor collector

installation. "his thing is big and black and it epands and contracts with temperature like

cra!y and unless the collector manufacturer and the system installer are fully aware and

competent at taking this into account for your uni'ue roof surface% the end result is eventually

a roof leak. "he single most important aspect of solar collector design is compatibility with

the roof. +ot Sun is very competent in this regard.

)ou&ll find a formburied in the si!ing section. "he biggest hurdle we all face whenimplementing a solar heater is finding a space for the collectors that is large enough to do

what you want. "here are no magic answers. We want a south facing roof. :ast or west is O=

you don&t want a cover and you ust want a warmer pool in mid summer. , roof that is flat is

,ll products of this style #water flows up the collectors not hori!ontally and there are about

122-722 flow cores per 6& wide collector$ perform eactly the same because they are all the

same color and temperature #black and cold$ and that&s all there is to a comparative efficiency

test in this industry. We don&t need glass over the collectors because the air is warm relative to

collector temperature. If you&re comparing collectors based on performance ratings published

by an accredited testing agency you&re looking at the wrong features. If set up properly we can

make any of the 72 collectors manufactured in the 4S operate almost eactly the same% at top

efficiency.
