Benchmark - Tempo DBE to steel panel radiator at low temperature heating
This is a visualisation of the energy performance of Low-H2O technology with DBE. A benchmark with steel panel radiators; A single Jaga Low-H2O DBE versus two steel panel radiators.


• Both houses have the same heating power after the system has warmed up. A single tempo DBE in house one has the same performance as 2 steel panel radiators at water temperature 40°C.
• Jaga Low-H2O with DBE is only 1/3rd of the size of a steel panel radiator for the same output power at 40°C water temperature.
• Steel panel radiators need more energy than Low-H2O heat emitters to heat themselves up.
• Due to its low thermal mass, the Tempo DBE has low inertia and a very short heat up time. The house with Tempo DBE is warmed up in less time with lower energy consumption.

Progress in time - see pictures below:
time 00:00:00
Start. Both houses at 9,5°C with an outside temperature of 3,5°C
time 00:02:00
Both systems are taking in hot water, the return water is cold.
time 00:02:30
The
room in house one has already started to warm up. The energy in house 2 to goes into the steel radiators themselves.
time 00:05:25
Average water temperature in house 1 is higher than in house 2. The steel panels are still warming up.
time 00:10:00
The steel radiators in house 2 are still accumulating warmth, return temperature is about 5° lower than in house 1. DBE has used 500Wh less at this point
time 00:10:30
Temperature in house 1 is 2°C higher than house 2, with less energy used.
time 00:30:16
The radiators in house two have reached operating temperature after 30 minutes. One small DBE is as performant as two steel plate radiators, while saving about 500Wh on energy.
time 00:30:46
While less energy is used, the temperature is house is still higher, showing the DBE's performance.
time 00:59:33
One hour in the test both houses consume the same power from the flow water.
time 01:00:03
The temperature difference between the houses remains at a constant 2°C.
time 02:03:56
The average temperature in house 1 has reached a comfortable 18,02°C, house 2 is still a bit chilly.
time 02:05:11
Meanwhile the energy consumption remains at a constant. End of test.
