Ever so slightly longer than the OEM part I replaced (@1/4") so the holes for mounting were off. Not a big deal but the equipment cabinet is also not a great space to be working in. These newer heaters come without the 'onboard pressure switch/third grey wire'(now obsolete) of my original 2012. I didn't see the explanation on the Spadepot site(may have missed it) but you need to clip the molded plug from your old heater leaving an inch or two of wire, strip the red and black wires/twist them together, and reinstall on the circuit board where it originally went to 'jump/bypass/?" something in order for the heater/tub to work.

Super friendly customer service. Had a problem with the payment on the website super nice sales lady took my order on the phone. The heater was a direct fit. Easy to install. Working great.

Thank you for filling my order accurately and quickly. It is identical to the one we bought only a year ago. I hope it lasts longer. The one just taken out suffered electric failure. Why we do not know.

Arrived quickly, straight forward install except for extra wire. Quick call to tech support and the extra wire was an easy fix.

This was easy to install, fit perfectly and has been working perfectly ever since. Fast shipping!
