Constant HOT WATER from
Surplus Renewable Energy.
Your boiler heats water either from an engine heat exchanger or when you are connected to shore power, so if you like sitting in anchorage for a few days, you have no hot water.
We have two solutions that give you permanent hot water on board without using the engine or being connected to shore power.
Controller + replacement 12v 300w heating element.
Controller + Inverter + Existing 1200w heating element.
Solution 1 is ideal for yachts with 300w of renewable energy and at least 200Ah of domestic battery capacity.
Solution 2 eliminates the need to replace the heating element, but needs at least 600w of solar and 300Ah of domestic battery capacity. More of either or both is better.
Batteries are usually full by mid-day; the rest is discarded. Use that excess energy to heat your water.
When the batteries are more than 80% charged and the water less than 42°C the controller either turns on the replacement 12, 24 or 48v heater element in your boiler, OR turns on the dedicated inverter connected to your existing heating element. Switches off at 53°C. Only restarts when batteries again fully charged.
Optional remote panel. User configurable for voltage sensitivity, water temperature, and solar power output so that the values are customised to your installation.
