Hot water and heating at every time

The space saving all-in-one multifunctional storage bases on the Akku-ESP with integrated solar register and warm water boiler. The highlights of the product at a glance: hot water is stored ahead and thus quick and sufficient available in each consumption situation.

Solar thermic systems can be integrated at all times. Biosolar is optimal expandable by parallel connection to an Akku-ESP or Akku-solar buffer storage.

Dimensions: Biosolar 850, Biosolar 1000

your great benefit:
  • + optimal combinable with different heat sources (oil-, gas-, biomass boilers etc.)
  • + expandable by parallel connection for higher buffer volumes
  • + perfect combinable with the fresh water module EFM-30 for warm water heating
  • + connections for the integration of solar energy by solar battery chargers with plate heat exchangers
  • + installation option for total 5 temperature measurement points with standard immersion pocket and thus high flexiblity: depending on the immersion pocket resp. more than one temperature sensors per measurement point are possible.
