Storage water heaters
They are intended to store thermal energy from solar radiation and heat water to a desired temperature (some 55 °C) by a heat pump. For the Czech Pavilion we selected RBC 400 HP Storage water heaters with upsized inner heat exchanger surface area. This upsized surface area transfers reliably the output of both the solar collectors and the heat pump. Their inner surface is enamelled in compliance with DIN 4753 and protected against corrosion by a magnesium anode rod. The size of the vessels needed to be chosen with respect to a rather limited space reserved for our technology. They are placed in a small but high room on the gangway above a drinking water retention reservoir.
