Even with weather variations our results have proven
to be within 10 to 15% of recorded pool heating costs on actual pools. Using your Local fuel costs, weather data amount of shade hours
per day of pool blanket use, how warm you want to keep your pool - we take these
and many other factors into account to make sure your actual cost is accurate.

Wind is specified at the water surface and normal is 2.5 mph for
a wind speed of 10 mph at 10 feet elevation (which is how most weather stations measure
Unless you are on a hilltop or in a windy unsheltered location
It doesn't matter what type of cover you use, IT SAVES 50% OF
YOUR POOL HEATING COST. It prevents the biggest source of heat loss - evaporation.
For every gallon of water you replace in your pool you lose 8000 BTU's of heat.
Be realistic and specify overnight (12 hrs/day) cover use. Very
few people are diligent enough to "uncover only when swimming"
We even calculate the extra electric cost of additional pump runtime
if Heat Siphon needs to run longer than your pool pump timer setting. Default is
24hrs - change it if you use a time clock and don't forget to include the pump size
(HP or Kw) A 1HP (120v) or 1.5HP (220v) usually runs on a 15 amp breaker, while a
2HP uses a 20 amp breaker. Larger sizes are rare on residential pools.
Don't forget to pick the date you want to open and close your
pool - for outdoor pools this is limited to average daily air temperatures above
50F to avoid icing problems (both you and the heat pump).
Local Fuel Costs
Please provide your local fuel cost.
Look at your bill if you don't know - divide the total amount
by the number of Kilowatt-hours (KWH) of electricity for the cost per KWH.
For Natural Gas divide the bill total by the number of MCF (1000
cu ft) of natural gas used. A Therm is 100,000 btu's while an MCF is a million btu's
OR just fill in the name of your utility companies, and we'll
do the rest.
Installed Heater Cost
Please provide the approximate INSTALLED COST or total purchase
price for each type of heater you wish to compare in the fuel cost savings payback
analysis. A graph will be provided showing the number of seasons required to recover
the difference in cost. Heat Siphon is virtually ALWAYS the lowest cost pool heating
