Last one corroded
I bought 2 8 years ago. Both do a fantastic job but no options to repair and at over $200 I expect better quality
HWS wireless temp controller
purchased to duplicate original temp controller for added convenience.
excellent quality controller, works very well and offers additional location for convenience.
We have been using Rinnai gas hot water and space heaters for more than three decades. very high quality product which have given reliable and faultless service in all residences we have owned and occupied. the controller is a genuine Rinnai and operates as efficiently as does the original controller and would be expected for a genuine Rinnai product
I would unreservedly recommend this controller to all enquirers, and would additionally recommend Appliances Online, though we hesitated to spend the money initially, Appliances online offered the best price available and facilitated prompt delivery.
excellent product and service....highly recommended !
