Heating My Intex Pool with a Tankless Water Heater

This setup has been working for our family for the past month and a half, so I thought I'd share it. It has been very cheap to setup and operate as well as being quite convenient and effective. One thing I would like to stress is that I recommend using a natural gas tankless water heater, not a propane one, simply because the cost differential is astounding (propane ends up being about 10 times as expensive as natural gas for me). Obviously running a natural gas line is more labor-intensive, and many may not have access to it to begin with, but it's worth consideration. Here's a cost breakdown based on my local utilities for 1,000,000 BTU's of energy:

Natural Gas - $4.63 - (80% efficiency at $.40/CCF)
Heat Pump - $6.45 - (COP of 5 at $.11/kWh)
Resistive Electricity - $32.24 - ($.11/kWh)
Propane - $39.56 - (80% efficiency at $3/gallon for 20-pound tanks)

Here's a list of the main components of my setup:

Natural Gas Tankless Water Heater - $80

The pool is an 8,000-gallon Intex Ultra Frame. My estimate of .7 degrees of heat per hour is based on my measured usage of natural gas and the BTU's required to heat 8,000 gallons of water. My actual results have been much better (9 degrees in 5 hours today, with the help of a warm, sunny day).

Let me know if you have any questions and I'll try to give you a somewhat coherent response.
