Triple C
The place: newly built cabin accommodates visitors in the gorgeous Alpine scenery
Ski slopes and spectacular hiking trails make the valley of Sedestal a year-long worthy destination. Anders Jonasson, who often stays at his family-owned cabin in the valley, decided to build a short term rental cabin nearby for visitors wishing to commune with nature.
With 136m2 of floor space and three bedrooms, the new cabin can accommodate up to 10 guests comfortably. The traditional wooden structure is combined with modern and tasteful interior design, instantly creating a cozy atmosphere for guests to enjoy after a day of outdoor activities.
Mr Jonasson, who’s also the owner of Kinnan heat pump distribution company, knew that a good HVAC system was fundamental for this enterprise’s success.
- Winters are long and cold in that part of Norway, with the temperature often reaching -5˚C/-10˚C outside. Even during mild seasons, heating is necessary as the temperature remain quite low.
- The demand for hot water can be very high when 10 guests come home after a day of skiing and needing to shower.
- Although summers are mild, the daytime temperature can peak at 30˚C outside on the hottest days, therefore offering cooling option is a great add-on to the guest experience.
- As a short rental place, the costs of heating are incurred by the owner, not the users. Therefore, choosing for a high-efficiency system is necessary for the owners to avoid excessive energy bills.
The solution: ground-breaking Triple C amazes the owner with high energy efficiency
After considering the various options on the market, Mr Jonasson concluded that Triple C was the most suitable equipment. The unique Hitachi multi-split system can provide heating, cooling and domestic hot water using air-source heat pump technology. The condensing unit can absorb and transfer heat between outdoors and indoor air conditioning units and the water tank.
“My conclusion is that this Triple C is the best investment I have made in the cabin. Now I just want to install it at home too”

The energy performance of this system is particularly impressive.
- Connecting to up to 4 AC indoor units, the heat pump can generate heating from outdoor air at down to -15˚C.
- In the same way, the water tank can be heated at 55˚C with renewable air source at -15˚C. Electric backup can provide extra loads to warm up the water at 75˚C if necessary.
In the case of the cabin, one Triple C system was installed with two AC wall-mounted indoor units, one on each floor. To match with the modern wooden interior, they were painted in black.
The Triple C system also fuels the domestic hot water, used in kitchen and two bathrooms of the cabin.
“We have installed an energy meter to monitor the cabin’s energy consumption and separate electrical meters for both the Triple C outdoor unit and water tank.
Last year, for the total cabin’s consumption with heating minimum 10 of 12 months, we have obtained extremely low electricity consumption. The total for the cabin are around 5,500kWh/year. Without Triple C system, I calculate that we would have used at least around 12,000kWh/year, more than double.”
Mr. Anders Jonasson
In addition to superior energy efficiency levels, Triple C uses R32 refrigerant, which has lower impact on climate than R410A refrigerant – still often used in heat pumps. The ACs runs very quietly, for the guest’s satisfaction. It is also easy to maintain, for the owner’s satisfaction.
“There is no doubt that Triple C system saves a lot of power!”
