4 // 4 SOLAR SYSTEM WITH INTEGRATED OKSOL-150 TANK YEARS WARRANTY OKSOL-150 is an integrated solar collector that uses thermal solar power to produce Domestic Hot Water. The absorber, the forced recirculation system and a DHW storage tank holding 150 litres of water are all included in one single element. It uses photovoltaic solar technology to supply the recirculating pump, making it a totally independent system with no external power requirements. HOW DOES IT WORK? When solar radiation falls on the collector, the collector concentrates the heat and transfers it to the heat-carrying fluid circulating inside it. Its cover shape and selective treatment enable the whole surface of the fluid-filled heat-carrying collector to be made use of. As a result, the solar radiation reaches both the heat-carrying fluid and the photovoltaic panel, which generates electricity, causing the recirculating pump to run and the hot fluid to be conveyed to the inside of the heat exchanger. The heat is transferred from the collector to the tank by means of the pump controlled by the photovoltaic panel and the heat exchanger. On sunny days the tank will heat up to maximum storage temperature of 95ºC.

14 // 14 INDIRECT HEAT EXCHANGE SOLAR KIT The indirect heat exchange solar kit is designed for centralised solar heating installations with distributed back-up power. Each home has an individual back-up power source and its own interior distribution circuit supplying domestic water. HOW DOES IT WORK? This kit regulates the recirculation inlet to the home from the circuit previously heated by the solar collector. If the kit detects that a tap has been turned on and hot water is required, the flow to the heat exchanger is opened to preheat the domestic water inlet. When the hot water tap is turned off, the 3-way valve opens the bypass again and shuts off the flow to the heat exchanger. The shut-off valves allow the central recirculation system to be completely blocked off at all the inlets. You may complete the totally regulated installation with the solar domestic water kit
