The CTC EcoZentih i550 is a thermal store with built-in intelligent controls. As part of the EnergyFlex family of products the EcoZenith i550 offers a unique and efficient solution to your total heating and hot water requirements. A thermal baffle segregates the upper and lower sections of the i550 allowing the upper part of the tank to be heated to a higher temperature than the lower part of the tank. With the upper tank providing the elevated temperature required for hot water production and the lower tank providing the temperatures as required for the weather compensated heating circuits. Able to control up to 3 heat pumps with the facility for 3 independent weather compensated heating zones. Domestic Hot Water (DHW) is produced by large area finned copper coils capable of providing up to 600 litres of hot water at 40ÁC with a flow rate of 22l/m. Due to the low water volume stored within the coils hot water production is Legionella risk free. With the DHW a secondary return pump can also be directly controlled by the EcoZenith i550 and there is the ability to add additional DHW storage so the EcoZenith i550 meets the most demanding hot water requirements.Key features: intelligent thermal store providing both heating (LHTW) and domestic hot water (DHW), controls up to 3 CTC heat pumps and 3 weather compensated heating circuits, produces up to 40l/min of DHW safe from Legionella, built in 10kW solar coil and controller as standard, integrates with gas, oil, wood and pellet fired boilers, can control swimming pool heating, borehole recharging, comfort cooling and much more, heating system schematic produced with CTC EcoZenith i550 Dynamic PDF, with CTC Connect app the system can be controlled from your smart phone or tablet via the internet or SMS

- Built-in heat pump control - 4.3-inch touchscreen - Easy install - Available in two heights: 1654/ 1904mm - Smart Grid _ ready to adapt to electricity prices - Energyflex _ total flexibility to connect other heat sources - Can be controlled from a smart phone with CTC Connect+ - Built-in low-energy circulation pump An efficient indoor module with built-in heat pump control. CTC EcoZenith i250 is suitable for different heating systems: one- and two-pipe systems for radiators and convectors, as well as for floor heating. Radiators and underfloor heating are always at the right temperature thanks to the automatically-controlled mixing valve. Since the temperature is constant, annoying expansion sounds in the floor and pipes are absent.
