Same story in DK. I live in a house with this tech in. Also with a heat pump (ground version) and solar panels/battery to offset some of the running cost of this system. The house is uncomfortably warm during summer but ok during the rest of the year. The air is not humid enough for my tastes. The Danish company called Danfoss sells complete systems used to heat and ventilate houses. There are other systems perhaps better in terms of communication with others (control systems). My main problem with Danfoss is that I'm unable to control their products without mayor hacking. So I'm never going to buy from them again.

You are unable to regulate the temperature of the heating in your house?

  Probably unable to enjoy as much cooling as possible given existing insulation, unit size, etc. Humans don't sense temperature or wetness. We sense thermal energy flow. Two materials at the same temperature, one highly heat conductive and another poor at conducting heat will feel like they are are different temperatures. Eg, at room temperature, water and wool.

    People know if they step into a hot humid environment vs a hot dry environment. Perhaps they're just sensing some level of thermal energy flow at the skin and how fast sweat cools, but I think you sinuses, sense of taste, and lungs may also also add additional senses to differentiate.

    > “Humans don’t sense … wetness” I read this elsewhere too and think it’s worded incorrectly. Maybe our _bodies_ don’t have sensory receptors for wetness, but humans can “sense” it by other means (e.g. by observing change in friction, stickiness, etc) Our bodies don’t have receptors for our spouse’s emotions, but I can “sense” when my spouse is in a bad mood. Or maybe my English is just bad and it’s worded fine.

  The heatpump is not able to cool the house - per design. It would need air conditioning.. which would be expensive. The house is very well insolatated and therefore difficult to keep cool during the warm months. We installed film blocking some of the light on the HUGE windows which are part of the problem. So we are able to regulate the temperature but the house is warmed up during hot days and not always cooled down enough during the night.

    An air conditioner is a just a heat pump. Why can’t your heat pump run both ways? It’s not that much more expensive!

      This is not a supported feature.

    Tons of air to water heat pumps can run the cycle in reverse (cool your house) these days. I'd double check if it's a recent installation, it almost certainly does. If so, the question is what your heaters look like. Not every likes cold feet for instance.

      Danfoss which is the maker of this (ground heat) pump doesn't support this. This is per design. You can buy an add-on with a separate loop which I find silly.

    Thanks for sharing. Do you mean the air-conditioning would be expensive in terms of upfront cost? As I imagine, with the solar, panels, it would be an ideal combination during the summer.
