This depends on 4 main factors:
1. The thermal efficiency of the building (how much heat it loses and how quickly).
2. The design and installation of the hydronic heating system (how well it produces the heat, how well it moves the heat to where it’s needed, and how well it emits the heat into the rooms).
3. The heat source type (gas boiler, air-source heat pump, geothermal heat pump, etc.).
4. What the input price of the energy is (gas, electricity, waste heat, etc.).
From our experience if the entire system is designed and installed to perfection, the system can cost between $0.162 and $0.378 per hour of operation per 100m2.
We have also seen some poorly designed and installed systems which cost upwards of $3.60 per hour of operation per 100m2.
