Overheating protection - Thermprotect
Therm Protect
25.09.2017
Thermprotect® : Viessmann patented technology to prevent collector overheating by using a proprietary
crystalline coating.
The stagnation temperature is reduced by means of switching panel absorbers. Collector emissivity
increases beyond a certain temperature so the collector dissipates heat.
No overheating or vapour formation in the case of low heat demand
Advantage: No additional heat dissipation measures required. No need for dry coolers, pumps or drain
back tanks

Viessmann Solar Thermal Systems - Benefits
Therm Protect
25.09.2017
Solar thermal systems help save money by offsetting
fossil fuel (partly or completely)
Payback period as low as 7 years can be expected
even during low fuel market prices.
The systems require minimal user intervention and
maintenance; therefore running costs are low –
Viessmann collectors have been used for over 40
years; the oldest installations are still in operation
Solar collectors – especially vacuum tube collectors
can add to the aesthetics of a building.
Good for the environment as solar heating produces
no emissions at all.
Solar thermal systems help developers obtain LEED-
USGBC ® credits.
