Nick, you have left the house without communicating first. It I am not denying that you had issues with the heat pump and tv, but the problem was you were using the heatpump on air conditioner mode, that would blow cold air. The TV works as a monitor , this is listed on the advice, I can see that you did not read this. Unfortunately you did not tell us anything at the moment that would have been solve it instantly, instead of letting us know you stayed for the night and left the next day, that would have been solve instantly, you just needed to press the right buttom of the heatpump. I had no obligation to make a refund due the circunstances that you left, but I have done it anyway.
