General Information
upper tanklower tank
The CTC EcoZenith i550 Pro is a multi-tank with almost
unlimited possibilities.
The EcoZenith is intended for houses and properties with water-borne
heat. The multi-tank features include intelligent control, a water volume
of 540 litres, bivalent mixing valve, two hot water coils, a solar coil and
two 9 kW immersion heaters giving a total of 18 kW. You can easily add
another immersion heater as an accessory to provide total power of 27 kW,
controlled by the EcoZenith.
The control is specially adapted to simultaneously control up to three of
CTC’s heat pumps, but it will also control and optimise the following:
• Pool
• Energy storage in buffer tanks
• Three heating circuits simultaneously
• Solar panels and bore hole recharging
• Cooling (passive cooling), floor or fan convector
• Hot water circulation with time control
• Charging of extra domestic hot water tank
• Connected wood boiler, gas/oil boiler and pellets
The CTC EcoZenith is well-insulated with 90 mm PUR and is well provided
with connection options on both sides, ensuring clean and easy pipe
installations. It also provides for extensions and additions to the system in
the future.
The CTC EcoZenith i550 Pro is divided into two tanks which are isolated
from each other in order to be able to hold different temperatures in the two
tanks. This provides for optimal function and operating economy.
The upper and the lower tanks are connected by heat distribution pipes
which are especially developed for the solar energy to be able to form layers
optimally in the entire volume of the tank and act as flow-through of the tank
on wood operation, for instance. See figure.
