Solar Pool Heaters - An Explanation
Solar, Gas, and Electric are the only 3 options to heat a pool.
Gas heater costs $2700 and $500-$900 to operate and is the most expensive , that is why you usually see it to heat a 500 gallon spa attached to the pool.
You can drain a 100 gallon tank of propane if used to heat a 10,0000 gallon pool.
The warranties vary from 1-2 years on the heaters.
Heat pump electric costs about $4000+ electric hook up and 100-$200 monthly to operate.
It is much cheaper than gas and allows you to use the pool anytime of the year.
One caveat is you must prepare 4 days in advance to warm up the pool, only if you are NOT running the heater at a set temperature on a regular basis.
The warranties vary 1-2 years on the heaters and usually 5 years on the compressor.
The cost is $3500-$4500 and there is NO operating cost, because it works off the existing pool pump you already operate. It's just one more directional route to send the water before it reaches your pool.
The warranty are 12 years parts and labor on the panels.
The attachment process is key. We use hardware that attaches to the truss system and is slightly elevated from the roof allowing the panel to expand and contract without creating any roof abrasion.
We also provide a guarantee for the roof, against any leaks for the life of the system, because the hardware acts like a sled and allows rain and any fragments to wash away when it rains.
The only caveat is it is not year round at 80 degrees. December through February we call bonus months, because cold fronts are unpredictable and normally if you put on a light sweater, you inclination to want to use the pool isn't as strong.
So March through November is ideal for solar to achieve that 80 degree mark and it accrues heat at a 2-4 degree increase per day. A pool cover is recommended in March and November since we have nightime temperatures that fall into the 50's and can steal the heat from the surface by convection losses.
