The table below shows recommended figures that will help to calculate the power requirement in kWatts to install GABARRÓN Storage Heaters in the UK and Ireland.

To calculate the theoretical heat loss in a room it is necessary to match the room floor area with the total length of outside walls of this room. We should install the storage heater with the power immediately above the theoretical power obtained.

In bedrooms and kitchens it is possible to reduce the theoretical power required by 20%. But in the same way, all rooms located in a top floor would be recommended to increase the theoretical power by 20% too.
These figures have been developed to get a comfort temperature of 21ºC.


The table below show which storage heaters in kWatts is best suited for the area your looking to heat. All you need is the floor area and outside wall length to calculate your storage heaters. Over 1.50 kW and you may need two storage heaters.
