Whatever you use, a $100 investment in a solar blanket will help, especially for retaining the heat when pool is not being used.

From my own experience, a light blue, 12-mil solar blanket is probably the best all-around choice:

Hello,
I would say wood, if you have access to it.


I am new to the form and wanted to share information on a wood burning pool heater.
I constructed the system from about $230 worth of material and it had taken about 6 hours.

It is heating a 30,000 gallon pool, raising it about 5 deg F per day. The system does not look
out of place, but you be the judge.

I will try to enclose a photo.
If I can't please respond with an email address and I will send it to you.
Thanks.
-Mark

Without a doubt, an electric heat pump is the most efficient. The down side is, with ~110,000 BTU output, it may take a few days to heat the pool to the desired temp. Gas units usually have a much higher BTU output and can heat the pool sometimes in one day to a few hours. The down side is, you may need to install a 2" gas line to the unit. This will cost you bigtime on the gas bill.

How about solar. The sun is free if you have the room for them. You could also do a combo of solar and gas or electric.
Jandy does make a 95% efficient pool heater, The HI E2 but its big bucks

Here's the rundown as I see it:

- Solar pool cover: no brainer, everyone who wants a pool warmer needs to have one
- Gas: cheap to install, expensive to very expensive to run
- Solar: medium-low purchase and installation costs, requires a lot of sunny space, costs nothing to run, not good in cloudy or cool weather
- Heat pump: Expensive to purchase and install, cheap it run but only heats best when you don't need it
- Wood: Self-built is cheap, purchased is medium expensive to install, there are smoke and fire stoking issues but cheap to run if you have the wood and they heat all year round.

Barko - can you post photos of your heater??
~8,500 gal, ig, 12x24 vinyl, 1.5 HP Dual Speed Hayward Northstar, Wood-fired pool heater since Apr 09. Using Bleach and Muriatic Acid since I found CYA levels well above 100. Using electronic ORP/PH meter for testing as well as TF1000 DPD-FAS test kit for dosing. Got rid of major serious metal stains (TWICE now) from rusted out gas heater on the old vinyl liner . Poorly maintained till I got it. Apr 08. Here's what I did/do to revive and now maintain it:
- First went back to the pool school at Trouble Free pool and used the BBB method. I calculate the needed chemicals using The pool calculator
- Purchased and use a TF-100 from <link removed>
- Purchased Hanna pH/ORP for routine testing
- 25 May 09 installed SWG, and like it. ORP meters show negative numbers and are now not usable.
