What is the wattage of each heater as that's also important. If he is using 2 x 3kw electric heaters, with them both on full you will use 6kw per hour and get 6kw per hour of heat out of them. An air con unit will use 1kw and give 3kw back out so make sure you have done your load cals correctly.
I’m right in thinking it’s going to cost less than the 2 electric radiator things he currently has that cost him around 5-6 pound a day to run. Plus they can’t cook the shop in the summer. Is there any rough way of working out running costs of a/c I know it’s going to fluctuate a bit.
It’s not a over crowded place he works by himself and max maybe 3-4 people in there at any one time so nothing too major.
