Electric night storage heating is not considered the cheapest way to keep a house warm. However, the initial costs are relatively low - and considering some rules, the user can save electricity.
The electric night storage heater: costs and facts
In many old buildings, a night storage heater was installed to replace the then usual coal stove. The heating was charged at the cheaper night rate, then to donate heat during the day.
The fact that the old buildings, however, have a poor thermal insulation compared to new buildings, drives up the electricity costs for electric night storage heaters. The old devices are also usually oversized and have an outdated technology.
A modern electric night storage heater costs - compared to other types of heating - little in the purchase, I can install quickly and requires only minor maintenance. Effective thermal insulation is a prerequisite for the cost-effectiveness of this type of heating system.
Register your heating with the electricity provider for the low night tariff. On very cold days, there are sometimes extra recharge times per day, which you should discuss with your electricity supplier.
