ᐅ Cooling with air-to-water heat pump requires condensation sensor and transformer

Hello,
I always thought that you could automatically use a heat pump for cooling as well...
Unfortunately, my Elco heat pump requires a condensate monitor and a 24V transformer for this. The whole setup would cost me 1200€!
Is this effort worth it? I believe it will only cool down by 1-2 degrees or so, right?

It’s worth it if your house gets too warm and you want to avoid the effort of installing air conditioning. However, an air conditioner is much more effective. So, rather not.

I cool down by a maximum of 2°C (3.6°F), but I don’t have a condensation sensor either.

With an investment of 1200€, I would also rather buy an air conditioner... I use it occasionally in the summer, and it cools by about 2 degrees. It could cool more, but if the floor gets too cold, that becomes very uncomfortable.

Is a condensate sensor really necessary?

With such an air conditioning unit, you usually cool a room and have very high electricity consumption, right?

There are also units that can supply multiple rooms, for example, one for the bedroom and one for the living area... but you have to make sure they can be installed properly.
I believe the electricity consumption is not higher than with an air-to-water heat pump since it operates on the same principle.

The most important factor for comfort in summer is dehumidifying the air. Even if the temperature doesn’t drop by a degree, lower humidity makes everything more pleasant.
If you want some comfort, I would always start with a conventional air conditioner. In a new build, often just one or two units are enough, placed in central (preferably high) locations to continuously dehumidify the air and run at low power. Just like the heat pump of the heating system.

For electricity consumption in a new build, I would estimate about $100 per year for an air conditioning unit (2.5 kW is sufficient if it runs continuously), assuming the summers remain similar. So it doesn’t get extremely expensive. Even better if you have photovoltaic panels on the roof...

This can be well supported by cooling the heating surfaces.
