Heating cost : 1/3 that of fossil fuels, energy efficiency proven !


Phoenix’s heating energy efficiency measurement test
demonstrated heat amount of 1,197Kcal/kw !


[ Test content ]
Measuring energy efficiency from the power consumption of the Phoenix
that heats the pool water.
(Heating the pool and Phoenix with closed circulation)


The temperature of the water leaving the pool is OUT, and the temperature
of the water heated by the Phoenix and entering the pool is IN.
Calculate energy efficiency from the temperature difference between IN and OUT
and power consumption (“Power” in the table).
Flow rate L/h × (Water temperature IN℃ – Water temperature OUT℃) = Amount of heat Kcal/h
Heat amount Kcal/h ÷ Electric power kw = Heat amount Kcal/kw


Phoenix heat amount transition test

February 29, 2024
Temperature: 11.4℃

[ Result ]
The time sequence data at 11:45 recorded a heat amount of 1,197Kcal/kw.
The energy produced was 337Kcal more than the conventional wisdom of 860Kcal/kw.


[ Consideration ]
These results demonstrate that heating can be done with less power consumption
than conventional heating methods.
Additionally, based on the results of the water temperature transition test
described below, the temperature of the water heated by the Phoenix is difficult to drop,
so the time the Phoenix operates for heating will also be reduced.
From this, it can be inferred that heating can be performed with further reduced power consumption.





Phoenix water temperature transition data

February 29, 2024


[ Test content ]
10L each of Phoenix-heated and boiler-heated water was placed in a plastic bucket,
and the temperature was measured over time.
Phoenix heating : Tap water is heated to the initial temperature of 25.2℃ in Phoenix.
Boiler heating : Tap water is heated to the initial temperature of 25.5℃ using thermal power.


[ Result ・ Consideration ]
The water temperature after 85 minutes of Phoenix heating and boiler heating was
-7.1℃ for Phoenix heating and -8.0°C for boiler heating.
Under the same conditions, there is a significant difference in Phoenix heating of 0.9℃.
This time we tested a small amount of 10L, but we believe that there will be an even greater
difference in large capacity applications such as heated pools and bathing facilities.
When maintaining a constant temperature, a small water temperature drop rate leads to a reduction
in heating energy, and Phoenix heating has an advantage in terms of energy conservation.
