Yes it’s heated with floor heating plus you can adjust temperature from the two electrical heaters with remote control.
We also do have ceiling heaters and one for the glass roof. These ones you can just put on or off.
For winter time we always turn on the floor heating as well.
During summer it can get quite hot, we recommend having the terrace door a bit open during daytime. Heaters will not be on during summer, if you need them you can just turn them on.
