The residual heat is removed from the heat exchanger shortly, without influence of the temperature lamination in the boiler. Because of the lower temperatures of the separate cold water connection is a faster cooling as by the internal exscaling not possible. Connecting dimensions: For an external cold water exscaling you need 1 cold water supply 1/2“ (max. 6bar) and one cold water discharge.
