It has a thermofused porcelain enameled inner cylinder for cylinder longevity and hygiene. The polyurethane insulation between the inner cylinder and the outer galvanised casement is 128% thicker, resulting in the hourly standing heat loss decreasing from 108 watts per hour to 50 watts per hour, a 50% decrease on the 150 lt. It is renewable energy ready for a Solar Retrofit System or a Heat Pump. The units can be installed horizontally or vertically.
