Hybrid water heater
Hybrid water heaters offer a new way of water heating using environmentally friendly energy sources. Solar energy is used to produce a DC current using photovoltaic (PV) cells that heats water in the boiler. The unique solution incorporates a direct connection of the heating spiral to the photovoltaic panels, resulting in a minimal power loss and highly efficient operation. The design also provides thermal safety features and ensures secure control of the entire system. The heating system is suitable for use in virtually every family home or industry buildings. The system is simple to install, can be placed at variety of locations. Operation of photovoltaic panels is maintenance free and the connection with water storage is straightforward using a thin electric cable. Ecologically produced electric power using photovoltaic panels is consumed directly by the producer. Planning permission is not generally needed for installation and it is not necessary to buy any accessories. So far, it is the most effective and loss-free use of green electrical power produced by PV cells.
Technical description of the system
Electric water heaters type LX ACDC/M and M+K use two sources of electric power for water heating. Alternating (AC) current comes from the mains and Direct (DC) current is produced in photovoltaic panels. It provides ecologically clean hot water production and helps to save significant funds to the user by saving on the gas and electricity from the grid. Moreover, model M+K has built in tubular heat exchanger for warmth supply from the external source. If you use less modules (4pcs=1,0kW or 6pcs=1,5kW) it is necessary to change the power cable to the appropriate contact. Performance type A = 1,0 kW, B = 1,5 kW, C = 2,0kW is marked at the appropriate contact directly on the spiral. Transfer of the cable to the appropriate contact can be performed only by the authorised personnel! Water heaters LX ACDC/M and M+K are recommended for use with photovoltaic panels that have these parameters: 30V +- 10% and 8,3A +- 5% / 1 panel.
The temperature indicator that transmits information about water temperature in the heater is located at the top of the boiler. The storage tank is insulated with hard polyurethane foam that minimalises heat losses. Electro installation is placed at the bottom of the heater, under the easily removable tank cover. It is possible to set the water temperature with thermostats between 0 – 80°C according the scale marked on the thermostat button. Input of cold water is marked in blue, output TUV in red colour. All metal parts are corrosion protected with.

Solar water heating
Water heaters LX ACDC/M and M+K are designed to be used with both electric power sources. Stable AC current source from the mains permanently heats the water to the temperature set on the thermostat T1 (AC). In practice, the temperature around 45°C is recommended. After the preset temperature is reached, the thermostat T1 (AC) switches off the AC current supply. DC current from photovoltaic cells heats the water further until the preset temperature on thermostat T2 (D2). Recommended maximum temperature is 75°C. In case the water temperature decreases (water consumption) under 45°C, water is heated very quickly and efficiently by both currents. When reaching water temperature above 45°C, the supply of AC current will aically switch off. In winter period (1.11. – 1.3.) it is recommended to set the thermostat T1 (AC) to a higher temperature concerning the lower sunlight.
