A domestic hot water station that is a complete module with heat exchanger, thermostat knob, circulation pump, etc. It is particularly suitable in systems where a built-in plumbing loop cannot be used for any reason, or if the existing plumbing loop or water heater has broken.
Thanks to the design, the amount of hot water produced can be high, even if you do not have a larger tank volume as a backup - because of the heat source that comes with it.
