OverviewUsing storage heatersPrinciple of operationTypes of storage heaterRegulationsApplicationComparison to other heating systemsEnvironmental aspects
Storage heaters can be cost-effective if used properly, but control may be trickier than fuel-fired systems. Storage heaters generally require two power circuits, one for on-peak and one for off-peak electricity, and two power switches, which are switched off during the summer when heat is not required. During other months the off-peak switch can be left on at all times, with the on-peak sw…
