NEW from Factory: This is an authentic Watkins part number 73790 - a 1.5kw/6kw No-Fault Heater. NEW. Not a knockoff! Used on all 1995 to current, 110 volt and 220 volt model HotSpring & Tiger River spas. Watkins manufacturing has replaced old units with this universal 6kw heater.
Plumbing of spas manufactured between 1997 and 2002 will have no issues realigning the plumbing of the old heater element with this new one.
Spas dated 1995 & 1996, will require a plumbing retro-fit Plumbing Kit (WAT 71557) to hook up the new heater.
We also recommend that when you are switching out this unit, regardless of year, to replace the Thermostat (WAT 38415 or 39530) and Hi-Limit (WAT 38416 or 39525). It is easier to do it now, while you have the spa apart than to do it down the road. We list these in our store (Parts Category).
Please contact us via email if you have any questions. Let us know what year, model, and serial number your spa is at time of inquiry. Your spa serial number is typically on a sticker on the inside wall (inside component cabinet) of the spa.
All parts from Mountain Spa Guys are BRAND NEW, from factory. NO Rebuilds!
