Hi, everyone. I'm new to the hot tub world, so go easy on me! I just picked up a 2001 Cal Spa model 2200, and I promptly burned out the heating element. I figure I'll go ahead and just get a new complete heater unit, and am curious which of these heaters I need on this page: http://www.spadepot.com/shop/Heater-Assemblies-Complete-C692.aspx based on this photo of my tub: https://www.dropbox.com/s/14zf0y6rvjua1v7/IMG_8099.jpg?dl=0 I'm guessing it's this one(?): http://www.spadepot.com/shop/Cal-Spas-XL-Heater-Assembly-Replacement--P9546C692.aspx Guess is based upon the fact that they look pretty much identical (I know looks don't always mean much though!). A followup question (for those who feel like helping even more): My circuit board is problematic in that it doesn't shut off the heater when it get's to its set temperature, so I plan on replacing it. Based on the stamp on the current chip ( https://www.dropbox.com/s/g3x51xyo8wu1nx8/IMG_8116.jpg?dl=0), I see that I need an "2200R1D" circuit board. My question is, will a 2200R1A/B/C board work as well? Some sites show them as interchangeable. The layout of the board looks exactly the same between all the letters...just the design of some of the capacitors (I think they are) are different (different color)...see http://superior-spa-pool.com/Cal-spas-ele09100206-circuit-board-2200ria-52195-02.html Thanks in advance for the help!
