CTC EcoHeat 400

Heat pump for geothermal, ground and water source heat
New, quiet and efficient CTC EcoHeat with touchscreen and Energyflex
Control and set
The 4.3-inch colour touchscreen has clear symbols with easily understandable text that makes it easy to adjust the heat and hot water or to retrieve a variety of information about the operation.
New design
CTC EcoHeat 400 has a new white design. We have equipped the product with a wall cabinet that is available in three heights. A cabinet of 146 mm is standard. Wall cabinets can be combined for a neat and attractive installation.
Effective and quiet
CTC EcoHeat 400 has top efficiency, thanks to a newly developed refrigerant circuit with electronic expansion valve and an efficient compressor. Compressor and refrigeration components are enclosed in a separate, sound-insulated unit. This provides exceptionally low noise

and makes it the quietest geothermal heat pump we’ve ever developed.
Lots of fresh hot water
A new technical design means that we have increased the hot water capacity. With CTC EcoHeat 400, we guarantee legionella-free hot water. Our unique solution produces hot water as it is needed.
Fits multiple systems
CTC EcoHeat 400 is suitable for different heating systems: one-and two-pipe systems for radiators and convectors, as well as for floor heating.
With the shunt group 2 accessory, you can control two different radiator systems.
Cooling
Now you can also get cool in summer, supplement with CTC Comfort which uses the borehole’s cool temperature for pleasant cool air.
Even temperature without noise
At CTC, we have chosen a proprietary technology that provides much more even heat. Radiators and floor heating are always at the right temperature thanks to the automatic shunt.
Since the temperature is constant, you avoid the scourge of expansion sounds that make annoying clicks in the floor and pipes. A difficult problem for many manufacturers
Freedom that doesn’t cost extra.
Energyflex gives you the freedom to supplement with other energy sources. Thanks to two ingenious connections, you can supplement with solar heat, or have a water-jacketed stove provide warmth, or connect a pool so you can also enjoy the warmth in summer.
CTC has developed the industry
We develop all of our heat pumps in Ljungby, Sweden. The roots go back to 1923 when we began to heat Swedish homes. We were the first with heating boilers with built-in hot water heating and we were the first to introduce heat pumps for air/water. It is therefore no exaggeration to say that we have developed the industry.
