The best way to heat your above or in-ground pool!

10-15° F warmer pool with FREE HEAT from the sun!

1. How big is the Pool?

When sizing your solar system it is important to know the surface area of your pool.

Multiply the pool length (ft) by width (ft) to determine the surface area of the pool.  Multiply that number by one half (1/2).  This is the minimum solar panel area, in square feet, required to heat your pool at  50% of the area of the pool (clear southern exposure).

If your solar panels can not face south but to the west (75% coverage required) or you are heating an indoor pool (100% coverage required), you will need to adjust your percentage coverage calculation.

2. How big is your roof? 

The panels come in standard 8ft, 10ft or 12ft lengths.  They should always be installed vertically.

It is advisable to leave at least 6inches around the perimeter of the panels (or as dictated by local code).  For example, if your roof measurement from eave to peak is 9ft, you can fit 8ft panels on your roof.  Measure the width of your roof to determine how many boxes will fit on the roof.  The width of one panel is 12.5inches (total header length) and 11inches (width of rubber)  We recommend that the panels face south, southwest, or west.


3. How many boxes do you need?

Divide your solar panel area number (square feet) by the length of the panel you will use.  This number will be the number of boxes of panels you require.

For example, if you require 200 square feet of solar and you are using 10ft panels, you will need 20 boxes of 10ft panels

We do not recommend installing less then twelve 1ft wide panels, as pressure problems can occur.



4. Custom Sizes:

If your roof will not accommodate our standard sizes, ENERSOL can provide other panels lengths (1ft increments from 6ft – 20ft).  Measure your roof, from eave to peak (length), and the width of your roof.  Subtract at least 6inches from the length dimension – this is to leave room for expansion and plumbing. Subtract 2ft from the width direction. Panels are ordered by the box with the specific length required. For example, if your roof is 21ft across and 7ft from eave to peak, you will require 20 boxes of 6ft sections.


5. Installation requirements:

In addition to the panels, you will require a System Kit. This kit includes: an installation manual and DVD, installation tool, extra 0-rings, 0-ring lubricant, roof sealant, 2 end caps, 2 header end connectors,  and warranty card.  You will also require a valve to divert the water to the panels, either a 3 port manual valve, or an auto controller.



6Pump size:

A  well running ¾ or 1 horsepower pump can reliable pump water through a 100ft pipe run and up a 2 story rise.  Above ground pool pumps are less efficient, can get air locks, and can only pump 50 feet. In general in ground pool pumps are much more efficient and can pump longer distances.


7. Special roof types:  

Installation on a metal roof: Attach 1×6 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 1×6 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 larger than the lag bolt, allowing it to go down through the cement tile into the wood below.  The supplied lag bolts may not be long enough as they must pass through the cement and securely fasten to the wood below.

**All penetrations in the roof must be properly sealed.  It is the responsibility of the person doing the installation to confirm that correct roof sealant is being used and applied correctly**

** If you are unsure about your type of roof, please contact your roofer for suggestions on installing the system**


8. Other Installation Options :

If your roof is not large enough, or in the correct orientation, you may want to consider an alternate option in 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.

9. Plumbing and tools:

Plumbing: Enersol suggests the use of 1-½in or 2in PVC piping to complete your pool heating project. ABS pipe does not have UV inhibitors and will break down when exposed to the sun.  Aheavy-bodied PVC solvent-cement is recommended for each glue joint.

Tools:  The system can be installed with standard hand tools, some of which include: variable speed drill, 3/8in socket driver, chalk line, lever, tape measure, hacksaw, utility knife, ladder, safety equipment.


10. Installing your system: Instructions, including a DVD, are included in each system kit or can be downloaded.


Solar heat
When considering a heat source for your pool, you only have to look up to realize the primary benefit of solar heat – it’s free heat from the sun! With uncertainty and rising costs in the gas and power markets, the price for solar will not change. It will be free for life. Using your existing pump and filter, our easy-to-install solar pool heater ensures warmer pool temperatures, no monthly heating bills, and is proven to be the most cost effective way to heat your pool. Get the most out of your pool by extending the swimming season and have more fun–courtesy of the sun!
