About Thermo-Fresh
Thermo-Fresh-Heizsysteme GmbH, based in Seefeld near Munich, develops and manufactures the modular ThermoSafe heating system for single and two-family homes in both existing and new buildings. The system consists of a laminar stratified storage tank (ThermoSafe Wärmetresor in 550, 850 and 1000 litres as well as MINNI storage tanks with 120, 200 and 300 litres), pre-fabricated hydraulic modules such as a fresh water station, ThermoSafe Box and modules for additional heating circuits, plus optional control. Domestic hot water is not stored in reserve but heated on demand in a flow-through process via a stainless steel Micro Plate Heat Exchanger (MPHE, 50 kW), which reduces limescale build-up and Legionella formation and improves condensing boiler efficiency through cold return flow. The system is manufacturer-neutral and technology-open for heat pumps, PV, solar thermal, wood, pellets, oil, gas, combined heat and power (CHP) as well as local and district heating. The systems are delivered fully configured and pre-assembled to the plumbing and HVAC trade.
