Night storage heaters improvements in modern systems

Night storage heaters and electric storage heaters still exist. Compared to the old, power-consuming night storage heaters modern heating systems have been significantly improved and have lost some of their disadvantages. Read here what is new in modern night storage heaters.

power consumption

The enormous power consumption was always the manslaughter argument in conventional night storage heaters. In modern systems, some things have improved considerably in this area.

The LCA on heating with electricity is still conceivably bad - but in terms of consumption, a lot has changed:

An independent test institute has tested a modern electrostatic storage system for its consumption.

In an average sized experimental living room, a modern system (single oven) was installed. The test conditions were an outside temperature of -1° C and a set room temperature of 21° C.

During an operating time from 6 o'clock to 22 o'clock the heater with 2,2 kW power consumed a total of 14,05 kWh, the 3,5 kW night storage heater about 24,5 kWh.

It is interesting to note that modern electric storage systems today manage with much less kW than old night-time heaters and can therefore be connected to ordinary 10 or 16 amp sockets.

Modern cores

Modern electric storage systems use improved cores and much improved control electronics that relies on frequent recharge rather than overnight charging. This takes into account the fact that there are hardly any more the classic low-load tariffs anyway, and then only with minimal savings compared to the household electricity.

If the "low load times" with reduced electricity supply are eliminated, it is also unnecessary to recharge the heating overnight.

Higher heating temperatures

Modern cores made of innovative materials, such as chamotte with a high proportion of aluminum dioxide, can heat up significantly higher than the classic magnesite storage stones of classic night storage heaters. While the maximum core temperature is 650° C, modern fireclay cores can reach temperatures of up to 1,500° C.

Voting on photovoltaic systems

Modern electric storage systems are designed from the outset so that they can use the self-generated electricity from the photovoltaic system.

Above all, the feed-in options and the reduced performance of the storage systems mean that the entire solar power can optimally flow into the new storage systems. There are also special 1.5 kW systems available to create a way to heat electricity for smaller systems.
