Solar-powered Water-to-Air air-conditioning or heating on a Yacht - no noisy generator or inefficient inverter! In the past, comfort required staying tethered to shore power on the dock in a marina. But you purchased the 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.
Imagine navigating by day in a comfortably air-conditioned/heated helm while recharging batteries and desalinating enough water for the evening. (See our 48v DC Direct Water-Maker.) 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.
~Equivalent to 32 to 42 SEER! Our DC-Direct Chillers are ABSOLUTELY the MOST EFFICIENT solution available or manufactured anywhere worldwide! Chillers with separate air handlers are well known to be the most efficient solution to heating and air conditioning. Our unique 48v / 24v DC-Direct Water Chillers utilize power from DC solar and DC battery sources without wasting 20% to 50% on 2 to 5 conversions before it reaches the chiller compared to AC-powered units.
MADE to ORDER - 3 Months to Delivery. (4-6 weeks to manufacture, 4 weeks Ocean Freight + 1 day-1 week US Customs + 1 week US Domestic LTL). 50% minimum to order, 50% balance due when ready to ship
A marine water chiller functions like an open-loop geothermal heat exchanger. Read Why is DC-Direct better?
What are Inlet water temperature limits for Cooling and Heating?
When Cooling, inlet water temperature must be >68℉ (20°C). When heating, inlet water temp must be above freezing or >34℉ (2°C). The minimum storage temperature for the closed loop circulation between air handlers and chiller is based on glycol/water mix used.
How to Heat when temperatures drop below freezing?
For heating below freezing, the exterior raw water circulation pump is left off. Instead a water heater (electric, diesel, LPG, or natural gas boiler) is used in the interior distribution loop.
With this system, can I use waste heat off the engines or generator to heat the boat?
YES, you can use waste heat off your main propulsion or generator engines by adding a passive heat exchanger between the engine coolant and the interior distribution loop. With some creative plumbing (bypass valves), a portion of the propulsion engine coolant could be passed through the raw water intake of the chiller (unsupported, could void warranty).
