Products Enersol Solar Pool Heating Package Selection & Sizing
| Package Selection & Sizing |
|
Selecting the right Enersol package for your pool is straight forward and simple. Just follow the steps below to figure out what you need and what package is right for you. 1. How big is the pool?Multiply the pool length by the width to get the surface area of the pool. Divide that number in half. This is your solar requirement number. This is the minimum amount of square feet of solar required to heat your pool, 50% of the area of the pool. If you are heating an indoor pool, you will need to have 100% coverage. If your pool is kidney shaped you can still just use the length and width for this calcuation or use the length and width specified by your pool supplier for your pool.
2. How big is your roof?The panels come in standard 10’ or 8’ lengths. They should be installed vertically. It is advisable to leave 6” around the perimeter of the panels. (For example: if your roof measurement from eave to peak is 9’, you can fit 8’ panels on your roof.) Measure the length to determine how many boxes will fit on the roof. The width of the panels is 51” ( total header length.) and 48” ( width of panels.) We recommend that the panels face south, southwest, or west. Remember that the Enersol system is very flexible and you can install the pannels in many configurations if you have obstacles on your roof. See the Enersol Installation Videos for examples of panel layout options.
3. How many boxes do you need?Divide your solar requirement number by: 40 for 10’ panels or 32 for 8’ panels. This number will be the number of boxes of panels you require. (For example: if you require 400 sq ft of solar and you are using 10 foot panels, you will need 10 boxes of 10’ panels) *If your roof faces east, more panels will be required.* We do not recommend installing only one panel, as pressure problems can occur.
4. Custom Sizes:If your roof will not accommodate standard sizes, we can provide custom panels. Measure your roof, from eave to peak, and the width of your roof. Subtract 6” in both directions. (This is to leave room for expansion and plumbing.) Panels are ordered by sections with the specific length required. (For example: if your roof is 21’ across and 7' from eave to peak, you will require 20 6’ sections.)
5. Installation requirements:Along with the panels, you will need a System Kit, which is sold separately. This kit includes: an installation manual and DVD, installation tool, extra 0-rings, 0-ring lubricant, roof sealant, 2 end caps, a header end connector and warranty card. You will also need a valve to divert the water to the panels, either a 3 port manual valve, or an auto controller. 6. Pump size:A well running ¾ or 1 horsepower pump can reliable pump water 100 feet run and a 2 storey rise. Above ground pool pumps are less efficient, can get air locks, and can only pump 50 feet. In ground pool pumps are generally much more efficient and can pump longer distances. 7. Special roof types:Installation on a metal roof: attach 1X6 lumber, with lag bolts (not included) to the roof and then attach the headers (top and bottom) to the lumber with straps and supplied lag bolts. Installation on a tile roof: Attach 1X6 lumber with liquid nails (not included) to the roof and then attach the headers (top and bottom) to the lumber with straps and supplied lag bolts. Or, lift the appropriate tiles and secure the straps to the wood below. Installation on a cement tile roof: Drill a hole bigger than the lag bolt to go down through the cement into the wood below. The supplied lag bolts may not be long enough as they must go down through the cement to pick up the wood below. The provided roof cement will not attach to your cement, but to the wood. Be sure to seal the penetrations in your roof with the roof sealant in the system kit.
** If you are unsure about your type of roof, please contact your roofer for suggestions on installing the system**
8. Other InstallationsIf your roof is not large enough, or in the correct exposure, you may want to consider an alternate method of mounting the panels. Panels may be set on the ground with proper insulation (see installation guide), or on a rack built to support the panels at an angle of 45% or less, facing south, south-west or west.
