General Information
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 is less beneficial to heat
pump operation for the radiator requirement because of the higher operating
temperature. Furthermore, where solar panels have been installed, some of
the solar energy will not be exchanged in the lower tank.
Additional Domestic Hot Water
There is a possibility of increasing the product’s hot water capacity at certain
periods, with or without the help of the immersion heater(s). You can either
select extra domestic hot water immediately or schedule selection on a
weekly basis. When the function is activated, the product starts producing
extra hot water. The hot water is produced by the compressor working at
maximum temperature, known as full condensation. In the “Installer/Settings/
Upper tank” menu you can also select the immersion heater(s) to help to
produce extra hot water. Remember that the function “extra hot water” means
that more energy is consumed, especially if the immersion heater(s) is/are
used. See also in the “Installer/Settings/Lower tank/Timer lower tank” menu.
Extra Domestic Hot Water Tank
Another way of improving the hot water capacity is to install an extra hot
water tank. The EcoZenith is prepared for controlling this, which provides
the possibility of utilising 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 benefits in terms of operating economy using low
temperature in the lower tank are maintained.
Important to remember:
• Avoid running hot water at the highest flow capacity. If you run a bath
at a rather slower rate instead, you will get a higher temperature.
• Remember that a poor mixing valve or a poor shower mixer can affect
the hot water temperature.
