                  I replaced my original equipment round upright heater with this unit when the 30 year old unit started leaking. The newer box design fits well in my engine room. I needed to put a heat sensor on the tank itself and was able to remove a cover panel easily to epoxy the sensor on. Heats quickly and very hot which is excellent for 2 back to back showers each morning. I'm very happy with this product.

                    Ordered this to replace the original Seaward installed in our 2000 MH.
