Direct comparison to the 12-gallon (78-171211): identical construction and feature set, capacity and weight are the differentiators — 6-gallon at 18.6 kg vs. 12-gallon at 27.9 kg. Position the 6-gallon for smaller vessels and couples; the 12-gallon for larger crews and liveaboards. Both are premium-tier units vs. the aluminum-tank Kuuma and Seaward alternatives — the glass-lined tank and 5-year warranty are the key value arguments. At 18.6 kg, installation is a two-person job; confirm access and mounting location before ordering.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51025044111396,"sku":"78-170611","price":2859.29,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/ccf93ca3-e16a-4e87-9839-7de02ffcabef_e2c9ed78-2e3e-47fa-a561-2930f4ab9398.png?v=1783212810","url":"https:\/\/marisolmarine.com\/products\/raritan-6-gallon-marine-water-heater-heat-exchanger-78-170611","provider":"Marisol Marine Company","version":"1.0","type":"link"}
