Electricity as a heat source
Electricity is the cleanest form of local heat generation. CO2 neutral power based on renewables and potential savings through intelligent power management offer many plus points.
Heating comfort is a good thing. But only where it's necessary. Considering that you only spend a limited amount of time in the bathroom in the morning and evening, it may seem a little extravagant to provide cosy warmth in there all day long. However, some central heating systems only permit a limited application of heat where time and space are concerned.
In this instance, electrical heating systems provide an excellent addition. A high degree of installation flexibility and their spontaneous heat delivery ensure a feel-good factor that hits the spot, every time. Heat is generated directly at the point of use – rather than delivered through lengthy pipework from the boiler room. This brings two main advantages. Firstly, the investment outlay is low. Electric heating systems require no pipework, radiators or chimneys, which brings the purchase and installation costs down. Secondly, the running costs are also low.
Electric heating systems allow the use of cheaper economy tariffs. Furthermore, operation is almost maintenance-free. Yet they are certainly a serious alternative both as full and supplementary heating system. Particularly in modernisation projects it makes sense to replace existing night storage heaters with advanced, energy efficient ones that utilise the latest control technology.
Electricity from renewables
Electricity represents a highly universal source of energy. It is being increasingly yielded from renewables. Compared to nuclear power, its proportion increases all the time.
Current statistics from the Fraunhofer Institute for Solar Energy Systems (ISE) show that renewable energy sources (solar, wind, water and biomass) accounted for about 156 TWh of electricity generated [in Germany] in 2014. This is 6 TWh or 4 % more than in 2013. These energy sources made up a proportion of approximately 30 % of public net electrical energy production.
According to a study commissioned by the Federal Ministry for the Environment [Germany], it would be possible as early as by 2050 to cover all required energy from renewable sources.
