Jssailem,
Here is what I got off Facebook with a GOOD 5/8 C windless.
We don’t use much water over the weekend the marina has great restaurants and facilities.

Nice. Kumma was not known to have much insulation around their tanks. I’d replace the element and be sure the proper fittings are screwed into the inlets. Some folks used the wrong thread. They then leak. Might want to pressure test the tank and the water coil.

Thank, It hasn’t been used much. Serviced it. Guy wanted $200 for both but we traded him for this drawing I did of a Buzzards Bay 25 by N.G. Herreshoff instead.

If you are requesting water heater recommendations, the choices will be limited by the space available and your budget. At the high end are Raritan heaters. A 6-gallon model will set you back around $1K.

There is nothing wrong with a Kuma heater. In fact it is the only company that has made the effort to have their water heaters UL listed. As your photo shows, the tank is pretty well insulated. A Kuma much more affordable than a Raritan. Check FisheriesSupply.com and Defender.com for prices.

We are replacing a Whale with a Kuma 6 gal water heater.
If it broke but worked well enough before replace with something similar.

I was a HERS Rater. One of the things we did was to do a savings to investment ratios (SIR) for homeowners that were adding upgrades, energy efficient items to their homes.
So since I’m not paying for electricity, even if I put a dollar into insulation it would never pay for itself.

That would be true and supportive of your desire as long as you are plugged into the marina power source.

Would the insulation start to pay you back once you unplug, leave the dock, while still having the desire for hot water on the boat?

I chose to buy a water heater with a reputation for a well-insulated tank. I can go for 1-2 days without having to heat the water in the tank. Maybe it is not a complete ROI.

From a practical standpoint, I have hot water on the boat even when not plugged into the marina.
