Energy accumulators
Energy storing systems at home have experienced amazing advances lately. Houses are built with material that can keep cold or heat. Still, the development of accumulators is especially relevant.
Depending on the geographical situation of the house, heating expenditure represents more or less 60% of its total energy consumption. This amount can diminish if the correct heating system is selected. Although it is true that there is still a long way to go in order to store heat in a fully efficient and economic way. Yet, when it comes to choosing, the energy storing devices must be taken into account for they are evolving progressively thanks to new technologies.
In fact, energy accumulators are already an alternative to the traditional heating boilers. But, what is the function of those devices exactly? Do they consume less? Are they more efficient? Do they cause the minimum environmental impact?
Highly efficient
Installing energy accumulators as a heating and hot water system is less complicated than installing other type of devices, for they can be installed almost anywhere. These are modular equipments that may adapt to most needs. At the same time, their work is highly efficient.
These devices, which usually accumulate the heat over night, heat up the house during the day at a lower cost. If they are electric they can save more than 50% of the expenditure of the electricity bill.
It this is combined with the advantages of natural gas, which offers saving and comfort for home climatization, then we are talking about leak-proof chamber gas accumulators. These devices incorporate the advantages of hot sanitary water accumulated in a container whose temperature can be regulated from 40º to 70º C.
How do they look like?
Accumulators are similar to a water heater, a stove or a radiator. They store heat for hours and then they let it off slowly, according to the heating needs of the house in which they have been installed.
Accumulators are usually classified into two types: static and dynamic. Static ones are placed in small rooms in which permanent heating is required but in which there is no need to carry out an exact control of the temperature. Yet, dynamic accumulators are provided with a more precise load regulation system, which is why they are recommended in rooms in which a greater control of temperature is required or which must be heated up more quickly.
Among the advantages of accumulators we can mention that they have a great performance level with an inexistent maintenance. Another favourable characteristic is that with them different temperatures can be selected in the house. Besides, as has already been said, they can be installed almost anywhere, with no need to carry out works.
As to the environment, it must be pointed out that they pollute less than other systems. And from the point of view of consumption, using them reduces the risk to depend on a single energy source, mainly if gas and electricity are coexisting.
The only negative aspect is that their price is high as compared to the price of the traditional electrical devices. If the comparison is carried out with boiler-based and water circuit systems, prices are very competitive.
