power to heat
power to heat or energy destruction
We called this page "Energy destruction" although energy cannot be destroyed (but only be converted).
Nevertheless, what we describe here is what one would colloquially call energy destruction: the conversion of electrical excess energy to heat.
Task: using electrical excess energy
Energy suppliers are increasingly facing the problem of a highly fluctuating power supply by photovoltaic and wind power systems which do not comply with the required amount of energy (keyword: balancing energy or power-to-heat)
In these cases one would like to "destroy" the excess energy (or to say it better: to store or provide the electrical excess energy in the form of heating energy).
The same applies to times when e.g. engine-based cogeneration plants have to be run at an unfavourable operating point or are not allowed to supply.
But there is a practicable solution to using electrical heating elements for converting electrical energy to heat which e.g. may be stored in a district heat supply network or can be used.
Electrical flow-type heater
Thus, the low inertia of the electrical heater can be used during minutes when the electricity price is negative.
For example, the electrical flow-type heater is operated in the auxiliary circuit of the district heat supply line and will be connected by a circuit-breaker whenever there is excess energy in the network.
The thermal energy will then be transferred to the heat supply side or to a buffer storage. The electrical power installed in such an application will then amount from some hundred kilowatts to some megawatts.
The flow-type heater may be installed at any place in the network, depending on whether a return temperature increase or a variable lead temperature can be tolerated.
