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.

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.

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.

EcoPart - ground-coupled heat pumps

EcoPart draws low-potential heat from a ground collector. This can be either horizontal (buried 1.5 under the ground level) or vertical (70-120m deep boreholes). Ecological heat-transfer fluid circulates in the ground collector that is designed and calculated individually for each installation. EcoLogic is an intelligent controller that controls both the heat pump and an entire heating system; it can also control even a cascade of up to 3 heat pumps.

The central heating unit contains a control board that controls heating in the house, heating of DHW, heat pump operation, and switches output steps of the heating rod. Heating is controlled by OTC using both the outdoor and indoor sensors that are included in the packing. Heating water is mixed by the integrated 4-way valve.

The unit is divided into 2 sections - a lower zone for preheating DHW and heating water, and an upper zone for DHW afterheating. The heat pump is connected to the lower cooler section, working thus at lower temperatures for most of the time, just from time to time it heats up the upper section to a higher temperature sufficient for DHW. The electric heating rod in the upper zone is then used only for afterheating DHW to the set temperature. The controller connects the el. heating rod gradually, in small steps (1,5 kW), in order to reach a precise temperature and max. savings.

In order to avoid the main fuse tripping (esp. in houses where its value is low), the controller in EcoHeat measures continuously current in all the 3 phases of the main fuse and limits the power input when needed, the heating rod in 1.5kW
steps first, and after that even the heat pump. The current sensors (included in the EcoHeat packing) shall be installed on the mains supply (e.g. to the main fuse) and the value of the main fuse shall be set in the controller. This function enables using EcoHeat for heating even in houses with a low-value main fuse that would be otherwise unsuitable for operating an electric boiler and a heat pump.
