Three big, strong air-to-water heat pumps

Many customers have requested larger versions of CTC EcoAir, Sweden’s most widely installed line of air-to-water heat pumps. Now they’re here – three powerful heat pumps with impressive outputs of 15, 20 and 25 kW.

They convert air into heating and hot water. No drilling or digging are required. They are installed outdoors beside a wall and occupy minimal space.

Top-class performance, environmental characteristics inspired by the Kyoto Protocol.

CTC EcoAir 400
  • Three outputs that can be combined: 15, 20 and 25 kW. All three models have the same dimensions.

  • New compressor technology that significantly raises performance:  54 ˚C hot water down to outdoor temperatures of –20 ˚C.

  • 64 ˚C hot water at outdoor temperatures ranging from –10 to +40 ˚C.

  • Uses R407C, a significantly eco-friendlier cooling agent – ozone-friendly and 100% chlorine-free.

  • Has a large, sturdy condensate water tray with a heating coil that prevents ice formation.

  • Easy installation. Occupies very little ground area, simple pipe and electrical installation. Everything ready-connected at comfortable installation height with plenty of room.

Are you unsure which heating solution to choose? Or do you want the option of supplementing your existing system with solar heating, pellets or wood in the future? Good. CTC thinks along exactly the same lines.

The best thing about CTC’s heat pumps and boilers is that they give you infinite options. For example, you can start with a heat pump and supplement it later with solar heating, pellets, wood or another extra heat source of your choice.
 

In search of flexible solutions?

Few things are as uncertain as energy: supply, demand, taxes and subsidies. What’s most suitable today may be less advantageous tomorrow. For this reason, more and more single-family house owners are seeking flexible solutions that offer security for the future. 
 
This flexibility is made possible by two unique solutions. They may not look like much – just two ordinary ¾ inch sections of threaded tubing installed on all our new heat pumps and electric boilers.
But these connections are unique to CTC. We’ve chosen our own solution for utilising the energy from heat pumps, and for heating water for heating systems and tap water.
 

Solar heating? Just connect it.

We even have solar heating packages. What was once complicated is now simple.
 

Long live free choice!

More and more single-family house owners are seeking flexible solutions that offer security for the future. Many choose CTC because it allows them to add another heating source later on.
