Identical in capacity and output to the side-mount 11810, the 11811’s front-mount configuration suits engine rooms and lockers where the tank face needs to be accessible from the front — making connections, inspection, and servicing straightforward. The front-mounted heat exchanger ties into your engine’s coolant loop for hot water production underway, so you’re not relying on shore power once you cast off.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e6-Gallon Capacity\u003c\/strong\u003e — well-suited for couples and small crews; solid reserve for daily use without the bulk of an 11-gallon unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e120V AC \/ 1500W Element\u003c\/strong\u003e — shore power compatible; lower draw than 1800W units, suitable for 15A shore power circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-Mount Configuration\u003c\/strong\u003e — designed for installations where front-face access is required; easier servicing vs. side-mount in confined spaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-Mounted Heat Exchanger\u003c\/strong\u003e — engine coolant loop integration for underway hot water production\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum Tank \u0026amp; Aluminum Alloy Case\u003c\/strong\u003e — reduces galvanic corrosion risk; lightweight at 8.8 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\/2\" NPT Hot\/Cold Connections\u003c\/strong\u003e — standard fitting size for straightforward plumbing integration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL\/CE Certified, Ignition Protected\u003c\/strong\u003e — approved for gasoline-engine vessels; dual certification for US and European markets\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003e⚠️ Important:\u003c\/strong\u003e Heat exchanger is designed for use with \u003cstrong\u003eengine coolant only\u003c\/strong\u003e.

The sole differentiator from the 11810 (735-11810, side-mount) is mounting orientation — specs, capacity, and output are identical. At 8.8 kg it is marginally lighter than the 11810 (9.1 kg); confirm whether this is a spec variance or a measurement discrepancy. When advising customers between the two: front-mount suits installations where the tank face must be accessible; side-mount suits installations where lateral clearance is the constraint. Engine coolant-only restriction on the heat exchanger applies — flag for raw-water-cooled engine vessels.
