Arkitektvägen 45-47, Stockholm, Sweden


Tallstigen is a residential type building which has total of 35 apartments. Our company was responsible for all heating, cooling, ventilation, sanitary systems.
Whole house is connected to district heating and ventilation type is FX system (it means, that the air goes in through the walls behind the radiators and comes out from the house through heat pumps, which means that we can use this return energy into making hot water.
Heating contains of 2 heat exchangers, which are connected to a district heating and delivers heat into radiators. We have delivered and installed all the parts – piping, insulation and so on.
Water supply system is mostly visible, so we have used copper pipelines in the bathrooms. Distribution (hot, cold and circulation lines) to apartments are designed from stainless steel pipes. All laid pipes in the constructions are designed as pipe in pipe system.
Sewage system includes internal pipework made of cast iron pipes in shafts and PEH-pipes in apartments. We have used cast iron mainly for the soundproofing capabilities.
In this project, we have installed standing toilets, showers, bathtubs, kitchen mixers, sinks etc.
For the ventilation system, we have used EcoHeater which collects exhaust air from the flats and brings back heat from it via heat pump to the heating system.
We have also installed kitchen hoods, ducts, fireproof insulation, etc.
