The ESBE VMC300 series solar thermal kit offers a double function for sanitary applications: it diverts the incoming water if its temperature needs to be increased and at the same time guarantees the safety function of the leaving water to avoid burns*.

What is it used for?

Solar heating and drinking water installations.


- Designed for small solar heating systems (Kvs 1.5). For larger systems, see VMC500 Series pricing.

- Operation:

  • If the water from the solar collector is not hot, it is diverted to an additional thermal source, such as a gas boiler, and once heated it is mixed until it reaches a temperature suitable for DHW applications.
  • If the water from the solar collector is already hot, it is mixed directly for use as domestic hot water.

- Max. flow from the collector: 0.7 l/x (42 l/min).

- Water temperature from the collector: 95°C.

- Example of application: used in a heat pump, to divert hot water between the radiator circuit and the production of drinking water. It is the heat pump regulation electronics that determine when the transition is made between circuit A and B.

5 Stars. There are 5 of us and we are very happy with the hot water. After searching for information for almost a month on low-consumption hot water systems, we decided on b. heat only hot water. Delivery in just 3 days from the web order.

Delivery was delayed a day due to the height of the package but then everything was perfect.

Thank you :)
