Experiences with brine heat pump

Where did you get your temperature values from?

February 2017 226kWh Heating degree day total 440

hello everyone, I have been a happy homeowner for 1 year with a Novelan S/W pump/2x 99.5m probes, a 9.2 kwp photovoltaic system and since then I have had 0€ heating or electricity costs. on the one hand I am amazed at what is already possible today and on the other hand equally shocked at how much companies fool you with information out of ignorance and what obstacles the state and energy corporations put in your way.

best regards

How do you do that in winter? Or do you mean a net total of about zero, because the revenue from summer, when the heat pump is not running, balances out the costs in winter? (although self-consumption is financially better than selling?)? For me, 9kwp would probably be barely enough because the revenue in summer would hardly be sufficient to completely cover the costs in winter, but the running costs would already be lower.

I finance this through a surplus calculation. I produce five times the amount of electricity from spring to autumn than I consume in winter. The money I earn from the surplus electricity in spring/summer/autumn is used in winter to buy the electricity I lack. For 1kw, I get 12.3 cents but have to pay 29 cents if I buy it. And the money left over in spring is my profit, which was €590 in the first winter.

Hi!

How often do you run the program against Legionella in your system?

With our Waterkotte EcoTouch Ai1 Geo, the longest interval you can set is only once a week - is that really necessary? I wanted to ask how you manage this with your system?

What temperature? I currently have it set to 65°C.

Best regards & thanks
