Cooling with air-water heat pump, condensation monitor and transformer needed

Hey, I always thought you could "automatically" cool with a heat pump too... Unfortunately, my Elco heat pump also needs a condensation monitor and a 24V transformer. The whole thing would cost me €1200! Is this effort worth it? I think it will only get cooler by more than 1-2 degrees, right?

It is worth it if it gets too warm for you in the house and you want to avoid the effort of an air conditioner. An air conditioner, however, is significantly more effective. So rather no.

I cool down a maximum of 2 degrees, but I also do not have a condensation monitor.

With an investment of €1200, I would also rather buy an air conditioner... I use it occasionally in the summer, it brings about 2 degrees. More would be possible, but if the floor gets too cold, it is very uncomfortable.

Is such a condensate monitor really necessary?

With such an air conditioning unit, you are rather cooling a room and have extremely high power consumption, right?

There are also devices that can supply multiple rooms, one for the bedroom, one for the living area, for example... but it has to fit so that it can be installed. I believe the power consumption is not higher than with the air-to-water heat pump, it’s the same principle.

The most important thing in summer to feel comfortable is the dehumidification of the air. Even if it doesn't get a degree cooler, lower humidity makes everything more pleasant. If you want some comfort, I would always start with a classic air conditioner. In new buildings, often only one or two devices are enough, which constantly dehumidify the air at central (preferably high) locations and run at low power. Just like the heat pump of the heating system as well.

I would estimate the electricity consumption in a new building for an air conditioning unit (2.5 kW is enough if you run it continuously) at around €100 per year if the summers stay like this. So it doesn't get extremely expensive. Especially if you also have photovoltaics on the roof...

You can then support the whole thing well by cooling the heating surfaces.
