Hello everyone,
I have a question regarding a clever control of my heat pump. I have the following situation. We have a new building with only underfloor heating and a heat pump from Ait (LWD 70A) & a 10 kW water-driven wood stove + 1000L buffer.
Both systems basically work perfectly. However, I want the optimal setting between the two systems. Goal: To heat/as much as possible with the stove and heat domestic water, etc., and as little as possible with the heat pump.
The control itself is initially simple. If the buffer has a domestic water temperature of 51°C, then the heat pump does not switch on. Unfortunately, it is not so simple with the heating circuit, as it depends on the outside temperature (at least that’s how I understand it). Usually, I fire up the stove around 4 p.m., and it burns until about 10:30 p.m.
When the days were not so cold yet, that was also enough until the same time the next day. For a few weeks now, the situation has been different. And the heat pump runs too much for me. Sure, I could start the fire earlier in the morning, but I am also at work, etc. Regarding the domestic water, I could regulate it relatively easily via the switching times. I block domestic water heating almost all day. I only allow a small time window in which the heat pump may heat if necessary. And it complies with that.
But with the heating circuit, it doesn’t work quite like that. I can also change the switching times in the heating circuit and mixing circuit 1. How should I set this for the heating to make sense? As I understand it, the times for the heating are not blocking times.
If I have forgotten any information or if you don’t understand me, please let me know briefly. Because I am just an amateur.
It usually takes about half an hour until the stove reaches 65°C in the combustion chamber and the pump actually starts. Then it also takes quite a long time (2–3 hours) until the temperature in the heating circuit is built up in the buffer. Domestic water is always heated first. And I do not want the heat pump to start during that time. I actually want to give it only a small time window, such as 11 a.m. to 1 p.m. During this time, it may run if necessary but not outside these times.
I know there is the possibility to block the heat pump via the EVU contact as soon as I turn on the control of my stove. However, for that, I would have to pull a cable into the basement, and I do not really want to do that right now. I think this must surely also be possible via the control of the heat pump.
Thanks to you all in advance & best regards
