DC-Direct from the power source to load without any conversions = maximal efficiency! No longer does comfort require staying tethered to shore power on a dock in a marina. You purchased a boat to explore and enjoy peaceful, even exotic, remote anchorages. Then you discovered that meant running a large, noisy, diesel-hungry expensive, high-maintenance generator 24\/7 while cruising and at anchor, completely polluting the sounds of peaceful anchorage.\u003c\/p\u003e\n\u003cp\u003eImagine navigating by day in a comfortably air-conditioned or heated helm while recharging batteries and desalinating enough water for the evening. (See our 48v DC-Direct Watermakers.) After dropping anchor for the evening, you redirect that energy to cool down the salon and galley to a perfect temperature while preparing dinner and enjoying cocktails with a movie without the background drum of a generator running. After the movie, you open the salon doors to let the evening air swirl through the salon while retiring to your quiet bug-free air-conditioned cabin for a restful night's sleep. no need to get up during the night to fire up the generator if the battery gets low if you add one of our  Small compact ultra-efficient 2kw to 5kw DC-Direct battery charging generators that automatically starts when the battery is low, charges it, and then shuts down automatically.\u003c\/p\u003e\n\u003cp\u003ePerfect for off-grid island, or waterfront homes anywhere! We can nearly double the efficiency of an on-grid geothermal home currently using solar micro inverters!  This solution  can also turn any large insulated water tank into a 50 to 100 year natural thermal battery!  Minimizes or nearly eliminates the need for any chemical batteries  except to run a fan for overnight cooling or heating!  Building new, adding on, or elevating your home? Bury a 2000+ gallon insulated water tank under your home's concrete slab and even any thermal losses from the tank will help to cool or heat your home!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e~Equivalent to 40-50 SEER!

The chiller transfers heat from the internal water-glycol system to the exterior raw water for cooling or reversed for heating. A water-to-water heat exchanger is essentially two water pipes, isolated from each other,  transferring heat through a membrane without mixing, and circulation pumps. It's internally closed-loop, so not affected by the hot, humid air of the engine room or bilge.\u003c\/li\u003e\n\u003cli\u003eEach space on your yacht (cabins, salon, indoor helm) that needs cooling or heating receives its own appropriately sized, very quiet air handler (essentially a radiator, fan, and thermostat\/humidistat).
