I'm trying to source some storage heaters for our offices.
From what I've learnt from the Dimplex site, the amount of heat required can be calculated based on the room area, number of outside walls and whether cavity filled walls or not. The amount of heat can then be translated into an Input Rating required from the storage heater.
I contacted an electrical contractor today and gave them the above details.
One of the rooms is 54sq metres with one hollow outside wall. They suggested an XL24 from the Dimplex range, but this only has an input rating of about 3kw. I have calculated that an input rating of 7kw is required to get the room up to 21c (Dimplex recommended).
Have I missed something?
