Looks like a Seaward but poor insulation

Comments about West Marine 120V Marine Water Heater with Heat Exchanger, 11 Gallon, Front/Rear Mounts:

This unit looks like a Seaward, but does not perform anywhere near as well.
Unit has VERY low insulation factor and will jot hold hot water over nite! Just barely warm in the morning where the seaward that it replaced would still be plenty hot for 2 showers in the morning.
I cannot recomend this dollar for dollar the Seaward is a much better unit _ We truly regret buying this one!

Comments about West Marine 120V Marine Water Heater with Heat Exchanger, 11 Gallon, Front/Rear Mounts:

Its never fun when you know that something large has to be replaced aboard. My previous water heater stopped working. Luckily i have a rather large engine room so size wasn't a great issue. Its been very reliable, so much so that last winter when my fresh water system sprung a leak and all of the water drained out of my tank, I thought for sure this was a goner. I went and ordered a new heating element, once I was about to install it I noticed that the outlet was up high on the tank; which got me to thinking. I called Kuuma and they walked me through some tests to do including bleeding the system. It turned out that since the unit had an outlet on top, my unit wasn't dead at all!

Service and delivery comments:

Great customer service through Kuuma and they certainly saved the day in terms of giving me some suggestions to trouble shoot the unit!

Poorly designed for installation

Comments about West Marine 120V Marine Water Heater with Heat Exchanger, 11 Gallon, Front/Rear Mounts:

Poorly designed, most likely by someone who never installed or built anything. Numerous connections in front foul each other. Inlet heater hose from engine (thickwall hose) fouls drain valve, so that hose needs to be removed (thus draining tank) to open drain. Go figure. Right-angle fittings will not install directly to connectors; they will not spin on account of fouling other features. Mounting ears too narrow to allow your hand to slide back along bulkhead to access bolts (I bolted them upside-down, from below-- not fun). Wiring connections are directly under water connections-- a leak will fry fuses or breakers. Wiring pigtails as supplied are of different configurations-- you need to make your own. Whichever orientation you choose, make sure you have plenty of room all around (which few sailboats will provide).

What looked like a tidy, compact package was deceptively bad from the start. A respectable brand like Kuuma should know better; WM should have these products evaluated by qualified industry pros rather than by vendors' marketing people. I build Cherubini 44s (best boat in the world) for a living and won't spec in this product again.
