For a hotel or apartment complex where the last room is more than 30 meters away from the
DHW tank, a water pump (for example type Grundfos comfort UP 15-14 BA PM) should be
installed in order to obtain hot water quickly.
Remember to install a return pipe pump circulation of maximum Ø15 mm and make sure that
supply and return pipes are well insulated to minimise heat loss.
