Customer Testimonials:

John Donahue - Slinger, WI - July 2006 24 foot round Pool

"Dear Jason,
Here are the pictures from our pool heater.
We are loving it, thank you for the wonderful system.
John

(He extended the chimney up this high to keep any smoke away from the pool area and from his house & porch which are right behind the pool. He also lives in a very windy area, so the tall chimney needed to be attached to something for support, as you can see in the picture, this was a great idea! This is the highest chimney we have ever seen on our heaters and it's ok to do this, but usually a chimney half this tall would be perfectly fine.)
Take a look at the PERFECT installation of our heater, with the drain plugs, water bypass valves and pete port set for the digital thermometer, you can't do it better then this!

Gary Hurteau - Carleton Place, Ontario, Canada - August 2006 18 foot round Pool

Gary purchased our pool heater from a local dealer in Renfrew Ontario back in 2002 and has been very happy with the performance. You will notice some rust developing on the exterior of the heater, this is normal and can easily be painted with a can of high temperature black BBQ spray paint. This is about the only yearly recommended maintenance for our heaters and in 4 years, he has never done it. This shows how well our heaters hold up, even after 4 Canadian years of weather and no maintenance, our stove is in good shape. The 12 gauge steel used for the heater body is not even close to being worn out on his heater, even in it's current condition, with no up keep, it will last at least another 5-8 years.(much longer if it's painted yearly) You will also notice the design of the front door is different on his heater then todays heaters. The new design allows for better draft control and fire regulation.

Jack Harris - Newton, NJ - August 2006 Pool: 16'x35' - 3.5' shallow, 6' deep

"Hi Jason, I purchased your wood burning extenda-swim last July. It's been a much better product this year since I incorporated my solar cover... An occasional burn after a few cool nights or several cloudy days in a row is all it takes to get the water back up to 87 - 92 degrees."

Don Ferm - Arkansas - Purchased 1998 Pool: 18x36 In Ground, 23,000 gallons

"I had your heater for two full seasons and am very pleased with its performance. Thanks to you, I can now start the swimming season about a month earlier. In just two days time I can increase the temperature of the water to 85 degrees Fahrenheit, and if a cold spell comes during the season I can easily bring the temperature back up."

Daniel Klump - Ocala, Florida 5-16-2005 Pool: 13' x 28' In Ground

 

       

Richard Norton - Rogers, Arkansas - 1997

My wife and I have had an 18,000 gallon, 16'x32' in-ground pool for over forty years and never had a heater, it never seems to fail if you plan a pool party the water cools off and spoils your party. In the summer of 1997, this happened to us and I decided to spend the money and get a heater. I live inside the city limits, so natural gas was available and I thought that'd be the way to go, when I checked with the pool company on heaters, the range of prices on heaters was $1,500 up to $2,500, and that was the delivered price only, then they told me a licensed plumber would have to run the gas to it. This cost was approximately $1,000, Then they said I would need a licensed electrician to wire it in. This was another $300 to $500, and then I had to have final inspection on all of it. Bottom line, it was going to cost over $3,000, and then I was faced with the cost of gas, which seems to go up with leaps and bounds. Needless to say, I decided against buying one and thought, "there has to be a better way.

I was fortunate that my son and I own a business where we could build and develop our wood fired heater, we experimented with numerous versions until we had one that performed at the level that we wanted. I have had the heater for three years on our pool and am very pleased with its performance. In the spring when we open the pool the water temperature is usually 50-60 degrees and it takes 48 hours to raise the water temperature to 85 degrees. When I run the heater, I keep the solar thermal blanket on the pool."

The solar thermal blanket helps eliminate heat loss, especially during the night time hours. During the day, I add wood every 2 to 3 hours depending on the size of logs used and how seasoned or dry the type of wood. At night around 9 p.m. I fill the heater full of wood and close the draft control way down. The next morning around 7 to 8, there is still a good bed of coals and I start the process all over, most of the heating occurs during the day and nighttime is maintaining the temperature. During the three years I have used my heater, I have not used more than two ricks of wood in one season. 

Two years ago, a close friend of mine saw my heater and he wanted one for his pool, We built him one and he has experienced the same results. When I first started experimenting with these heaters, my wife thought I had lost my mind and she didn't want one. This spring I removed the heater to bring it to the shop to check it out for wear, etc. She said I better have it back before we open the pool. She wasn't going to swim in cold water. We decided that there had to be other pool owners that felt as I did, especially those living where natural gas was not available and we decided to start producing the Extenda-Swim Wood Fired Pool Heater.
