I had not actually used it for hot water in about two or three years preferring to take Joy showers off the stern or cockpit showers using a solar shower bag. Though it was a reliable provider of hot water when I was working and living on board in New York City back in the mid 1990's to 2001. I'd use it take a shower everyday before heading off to a midnight shift keeping electrons flowing through the wires in midtown Manhattan. Now that I am living on board only in warmer seasons and in more secluded locations I won't miss the unit.
The Paloma water heater on BIANKA was installed behind a custom built cabinet with some extra joinery to hide the gas supply line, water hoses and also an AC line for a microwave used by a previous owner located in another cubby.
Removing the wood covers showed the various hoses connecting up to the unit:
Two hand screws on the bottom sides of the heater allowed the cover to be removed:
It then was pretty easy to access the water heater connections and remove them:
The gas supply and water hoses came off pretty easy:
Two bolts and nuts held the bottom bracket of the heater to the bulkhead:
A single bolt and nut held a bracket on the upper part of the heater to the bulkhead. This was more difficult to access. So I went around the back and just loosened the screw until the nut fell off. I was then able with a little wriggling to remove the water heater from behind the cabinet:
With the Paloma water heater removed a nice amount of storage space was opened up:
I'm already planning on adding another spice rack below the cabinet. I'll see what else I can fit into the area left by the removal of of the Paloma. Always good to have more storage space on board.
