Additional Domestic Hot Water
There is a possibility to increase the product’s hot water capacity at certain periods,
with
or without the help of the immersion heater(s). One can select extra domestic
hot water immediately or schedule by week. When the function is activated, the product
starts creating extra hot water. The hot water is produced by the compressor working
with maximum temperature. In the “Installer/Settings/Upper Tank” menu you can
also select the immersion heater(s) to help to create extra hot water. Remember that
the function “extra hot water” means that more energy is consumed, especially if the
immersion heater(s) is used.
Extra Domestic Hot Water Tank
Another way of improving the hot water capacity is to install an extra hot water tank.
The CTC EcoZenith
I
550 is prepared for this and provides the possibility to utilize heat
pump energy to heat the extra domestic hot water tank. This means that there is a large
buffer with hot water, heated by the heat pump, while the operating economy advantage
with low temperature in the lower tank is maintained.
Important to remember:
◗
Avoid running hot water with the highest capacity. If you run a bath somewhat
slower instead, you get a higher temperature.
◗
Remember that a poor mixing valve by the EcoZenith or a poor shower mixer can
affect the hot water temperature.
For higher hot water demands, it can be more economical to set a higher temperature
in the lower tank instead of exceeding the temperature limit for the heat pump in the
upper tank. However, this means that the heat pump gets a less favorable operation for
the radiator requirement because of the higher operation temperature. Furthermore,
a
certain exchange of solar energy in the lower tank can fail to occur.
