Here I’m describing shortly how my heat pump was operating last winter 2007/2008, what were the temperatures, what were the costs and other parameters.
An average temperature in year 2007 was around 12 degrees Celsius – Slovenia, central location (this temperature is above average for our location). The winter 2007/2008 was not so cold but lower temperatures lasted quite long time. Here is the data what was happening in heating season 2007/2008:
- We switched on heating in September 24th 2007 and was stopped in May 10th 2008. The heating season lasted 229 days.
- Heat pump was operating 680 hours (approximately 3 hours per day on average)
- Total costs of operating for the whole season were 230 EUR (2550 kWh) - 1 Euro per day.
- Minimum outer temperature was -9.9 degrees Celsius. This peak requested heat pump to run 4,5 hours per day.
- Room temperatures were from 20 – 21 degrees Celsius (night temperatures around 19)
- Temperatures of medium from vertical collector to Heat Pump were from 7 (coldest days) to 12 degrees Celsius (at the start and end of season).
- Temperatures of water in floor heating were adjusted from 26 up to 30 degrees Celsius (talking for returning line – water temperature coming from floor heating back to the Heat Pump).
No maintenance was needed, no problems, just paying bills for electricity :-) I just switched on the heat pump in September and switched it off in May. If anybody has similar experience or totally different please add a comment. Thank you for reading and supporting this page.
