Pullin Evolution Stainless Steel Unvented Cylinder Hot Water Tank Mega Flow System DIRECT 1901 SOLAR

The choice of capacity for traditional cylinders is based on the hot water requirements of the dwelling. With solar cylinders the usable hot water will vary due to a number of factors such as siting of solar panels, time of year and weather conditions. For this reason, when choosing a solar cylinder you should ensure that sufficient usable hot water will be available during winter months where solar gain is at its lowest. For example a non-solar dwelling of 3 inhabitants with a bath and a shower would normally require a 145 litre indirect cylinder. However, in line with the ClearSkies* recommendation, at least 30% of the cylinder capacity must be dedicated to solar, therefore the same dwelling with a solar system would require a 210 litre indirect solar cylinder which would provide 143 litres of hot water during periods where there is little or no solar gain. For guidance please refer to the table below. Some applications may require larger water quantities or higher recovery rates, therefore it is important to calculate the hot water requirement before selecting the cylinder capacity.
