First of all, sory for posting in English. I have a Swedish heat pump and expertise in this country are limited.
I'm running a Thor 05-15 GSHP (three phase) and have recently moved on to an EdF Economy 10 tariff. Without any sort of effort, 57% of my consumption is off peak (0430-0730, 1330-1630, 2030-0030). With a little bit of care I can improve on that (having showers, using the washing machine, at the right times). However I'd really like to be able to control the heat pump so that it only switches on at off-peak times.
I have a 500 litre buffer cylinder for the heating which should
to balance things a bit and a 500 litre hot water cylinder.
I have tried playing with the heating a bit by putting a timer on the heating circulation pump - but by controlling the heat pump instead, I'd get the benefit of the buffer cylinder heat for longer. I could also live with the hot water in the cylinder until the next off peak heating cycle.
The heat pump control module is a Energi AB Stockholm Comfort Computer ES3 (if that means anything to anyone).
The system could be really good and efficient if the control module had a timer built in. I dont really want to fit one on the input to the heat pump as it triggers the 'loss of power' alarm. However if there was a way of fitting the timer between the main input and the actual pump control - that would be good. Or ideally reprogramming the module or buying a new one with timing capability in it.
If anyone can
, I'd be grateful.
Thanks (and sorry once again for posting in English. My Swedish really isnt good
