Question: How many units will a storage heater use per night?
Answer: Each heater will usually have a model number that will reflect the maximum number of units (in kWh) it will consume over a seven hour period.
For example, a XLS18N storage heater will consume an absolute maximum of eighteen units per charge, when the input has been set to the maximum.
