Night storage heaters are energy guzzlers
Modernization congestion of social significance. So far, there are no alternatives.
The completely outdated night storage furnace technology is a development of the seventies. The exorbitant high heating costs, caused by the high consumption, the inertia and inefficiency of the storage and heat emission and the inadequate control possibility of the night storage heaters let owners, tenants and payers despair for decades. But also the housing companies did not know further. Their rental income has stagnated for years at a low level because a much too high proportion of housing costs flows into the heating system. The consequences: too little return from the rents for the modernization, refurbishment and value preservation of tens of thousands of residential real estate. Thousands of settlements are now threatened in their economic viability and thus in their existence. In view of the housing shortage, a modernization congestion of social significance has therefore been built up to this day.
Uneconomically high investments or conversion to oil / gas / CHP / heat pumps.
There is every reason to suggest that as soon as possible in these settlements and apartment buildings the inefficient night
retrofit storage ovens. Alone – there are few alternatives. What in this sense is a conversion to a cost-effective
Driving investment makes: all based on fossil fuels systems (oil / gas boiler, CHP) have in common that in any case an expensive reinstallation of water systems, piping, storage and burner systems or even a CHP is necessary. And of course these residential units or settlements require gas or oil connections. Exactly all these apartments do not have, because the night storage heaters were indeed supplied and operated by electrical connection.
