Air-to-water CTC heat pumps

EcoAir 107 and 111 Air-to-Water Heat Pumps

EcoAir Air-to-water heat pumps gain energy from the ambient air even when the outdoor temperature drops to -15°C. The energy gained from a low temperature is “pumped“ to a higher temperature (as high as +55°C) and transferred into heating water that can be used for heating a house, domestic hot water or a pool.

Electric energy is consumed only for operation of the heat pump‘s compressor and fan which represents just one third of the energy supplied by the heat pump, the remaining two thirds are gained from the ambient air. This way about two thirds of all the energy needed for heating can be saved.

CTC EcoAir air-to-water heat pumps represent the most frequently sold brand of air-coupled heat pumps on the Swedish market. Their reliability and excellent parameters are proved by many thousands annual installations in the harsh Scandinavian climate.

EcoAir 115 and 120 Air-to-Water Heat Pumps with EVI Compressor

This new line of air-source heat pumps has been developed using the most up-to-date technology with the aim of reaching the best possible parameters. For the best possible exploitation of air energy, they are fitted with a new, extra large evaporator. For a high C.O.P. and effective operation even at very low temperatures, they are equipped with the latest compressors with a revolutionary EVI technology.

Thanks to that, the heat pumps work efficiently to as low outdoor temperature as -20°C, and can supply heating water of up to 64°C.

For air temperature of 2°C and heating water temperature of 35/30°C (feed/return – measured in compliance with EN 14 511) the C.O.P. reaches the value of 4. This is a very high value for an air-source heat pump, and the annual energy consumption of these heat pumps is fully comparable with ground-source heat pumps thanks to their high C.O.P. value.

Of course, all the advantages of an air-source heat pump are maintained, e.g. simple installation without costly ground works.

Like EcoAir 107/111 line, also EcoAir 115/120 heat pumps can communicate with EcoLogic Intelligent Controller that enables comfort control of your heating system and even a cascade of up to 3 heat pumps.

EcoAir 107 and 111 – EcoEl Air-to-Water Heat Pumps

This is a sophisticated system designed for effective use of a heat pump and other renewable energy sources. EcoEl compact indoor unit represents virtually a complete boiler room. Using its intelligent controller, it provides space- and DHW heating, and controls heating of the entire house ensuring the utmost use of the heat pump. That means that this device alone is able to provide for the heat needed for space- and DHW heating using the air-source heat pump and its own electric heating elements. Further heat sources – e.g. solar collectors, a fireplace inset or a wood-fired boiler – can be connected easily.

An integrated heating unit of EcoEl type contains everything needed for a domestic boiler room. Its compact size excels with little heat losses and occupies just a small space. It has been designed for the best use of the heat supplied by the heat pump and for its optimum operation.

The user friendly integrated intelligent regulator with a large display controls space- and DHW heating for the whole house. Both indoor and outdoor sensors as well as communication with the heat pump are used for precise regulation and optimum operation. When needed, electric heating rods are switched on in small steps. Therefore, the highest heating comfort is reached together with energy savings. Of course, also solar collectors or a solid-fuel boiler can be connected.

The controller is equipped with current sensors for the main fuse, so it is able to reduce immediately the power drawn for heating. Thanks to this fact, the controller will prevent the main fuse tripping, e.g. when an electric stove or a water well pump starts, however, this short heating interruption will not affect your home comfort in any way. This function enables that electricity is used for heating even in houses with a low-sized main fuse.

EcoEl can be retrofitted with a plate heat exchanger with a circulation pump in order to use solar energy. Solar energy can be used together with a heat pump, combining thus the most ecologic energy sources. In the summer, solar energy is used for DHW heating, and in the winter it helps in space heating.
