Just the bedroom. was about 2.2k to get it installed and have the fan unit out on the flat roof. No point in getting in anywhere else as we have a big open plan extension with bifold doors. The other thing we’ve done is get a blind across the skylight lantern which has cooled the house down massively.
Can also use it as a heater for just the bedroom as well in the winter.
Its mainly for nights when the bedroom gets super hot. Mind you I get ejected most nights for snoring and have to sleep downstairs
