Night storage heating: how can the costs be calculated?

You are planning to install a night storage heater or would like to move into a house with this type of heating? Then you should calculate in advance the approximate cost of the night storage heater, because the power consumption can be relatively high - while the maintenance costs are low.

Worth knowing about the night storage heater

The night storage heater saves one thing above all: storage space for fuels. That's why it was so popular in its early days, because in the 1950s, most of the houses had a coal stove, including a depository for the coal.

In terms of electricity consumption, old appliances are not very economical - at times of low energy prices that did not matter much. In poorly insulated old buildings with technically obsolete heaters, the night storage heater at today's electricity prices means a big cost factor.

In addition, the low-cost low tariff (also called night tariff) in Germany is no longer offered nationwide. In the past, electricity suppliers used this special tariff to secure the capacity utilization of the power plants during the night.

Who wants to calculate the cost of his night storage heater, the first must consider whether he will use an outdated or a new heater. In addition, of course, the thermal insulation of the house and their own heating play a major role.

With no night tariff the purchase of a new device will hardly be worthwhile. If your electricity supplier offers such a tariff, then this lies somewhere between 20 and 6 o'clock, possibly in individual sections pieced together.

The acquisition and installation costs for new equipment can be described as relatively low, also the night storage heater is low maintenance. These factors play an additional role in the calculation of the total costs.
