Plate I · Benefits

Lower costs, a better building.

What the Synenergi system means for the climate, the economics, the people working in the building and the technical installation – as stated by Synenergi.

01

Environmental

  • Meeting 2030 requirements already today
  • Significant reduction of CO₂ footprint – in excess of 80 %, depending on reference system and source
  • Opportunity to be virtually “off-grid” if combined with solar power and batteries
02

Commercial

  • A minimum 80 % reduction in operational costs vs. traditional solutions
  • ROI in 3–6 years, depending on specific context and requirements
  • Significantly higher valuation due to lower operating costs, and the ability to charge premium rents thanks to ESG credentials
03

Work environment

  • Improved indoor comfort – stable temperature and air quality
  • Flexibility – the same system can cool the building in summer
  • Keeps floors dry and decreases the risk of injuries from slippery floors
  • Completely quiet, compared with aero tempers and fans
  • Less maintenance – no filters to change, no fans to clean
04

Technical

  • System temperature 26 °C – a broader choice of heat solution
  • Heat spreads more evenly in large spaces than with aero tempers
  • Specially designed heat pumps allow for a very high COP
  • 5–8 kWh/m² per year, vs. more than 50 kWh/m² per year in traditional systems
  • Thermal storage in the floor keeps the heat indoors
  • The slab can be charged at night, when electricity costs are lower
  • Heating and cooling in the same system
  • Future-proof – the heat source can be changed over time
  • Floor load is unaffected by the system

Savings and payback depend on the building and on the system Synenergi is compared with.

Plate II · Illustrative cost comparison

Higher upfront, lower over the years.

Synenergi's own comparison with district heating: the investment is higher at the start, but the accumulated cost grows much more slowly – so the lines cross after a few years.

Plate III · Next step

Discuss your building.

New build or retrofit – if the building stands on a concrete slab, we can look at what a low-temperature floor system would mean for its energy use, comfort and costs. Useful to mention: the size of the building, what it is used for and how it is heated today.
