Hi Kate
For this particular model you have the choice of turning the heater function on or off.
The heater is ideal in cooler temperatures as it allows the dehumidifier to operate more effectively. For summer use as in your situation I would recommend leaving it turned off.
However I'd like to point out that all dehumidifiers produce a certain amount of heat when operating therefore they can increase the room temperature in summer.
In saying that, it depends on what you want to use the dehumidifier for that determines on how you use it. For example if you wish to use it to stop moisture related problems such as mould, dampness etc then you only have to turn it on once every few days or so to keep your home dry. If you want to use it to reduce humidity for comfort levels in summer then on the hotter days I would run it in conjunction with an air conditioner.
Kate; if possible I would love to have a chat with you over the phone to explain in more detail about what your best options may be.
You can contact me on 1800 122100
Kind Regards
