In times like the one we live in, with ever-increasing electricity prices, any solution to control and limit the impact on our pockets is welcome. From the search for the best price to the search for high-performance equipment… in this last sense, an interesting option in times of low temperatures can be to use a heat accumulator.

Heat accumulators are a system that allows us to heat the house without implying a decrease in the capacity of our pockets. These types of devices take advantage of times when electricity rates are cheaper to recharge and then we can heat the room at any time of the day.

Something like a kind of radiator but with an integrated accumulator that allows us to heat a house at any time without having to think about the hourly rate of electricity, whether or not it is more or less economical.

A heat accumulator works in the same way as an electric heater. It does this thanks to certain electrical resistors which heat up as the electricity passes through, which in turn heats the core of the accumulator, which is responsible for storing the thermal energy which it then gradually releases.

And this is the main difference from a normal radiator. Although it only heats up when we plug it in and time and flow don’t matter, a heat accumulator is charged with energy when it’s cheaper and then we decide when to release that energy charge in the form of heat.

The accumulators are intended to consume electricity during periods at reduced rates (hourly rate of discrimination TDH)

When talking about heat accumulators, it is necessary to refer to different types depending on how they release the energy they have accumulated. We thus have static heat accumulators, other dynamic ones and other solar ones, which are less frequent.

Static: these are the cheapest but at the same time the least efficient. These release the stored energy in the form of heat evenly and continuously, so that they provide a constant temperature. Dynamic: these are the most interesting, as they offer greater energy efficiency. Thanks to a thermostat, the temperature can be regulated and the heat transfer occurs at the request of the user. Solar: interesting for those who have solar panels, they favor self-consumption. They work with solar panels to heat water and store it.

Although dynamics are the most interesting, the two types of accumulators can be combined for economic reasons, since static accumulators are less expensive than dynamic ones. However, if possible, it is advisable to opt for dynamic heat accumulators.

A heat accumulator is a heating system and as such it requires an installation process which can be more expensive initially compared to the heating systems used. In return, they allow the accumulation of the energy necessary to maintain the temperature during the day in the home, with three advantages compared to a traditional installation:

It is not necessary to carry out any work Maintenance is simpler, since it suffices to carry out an annual cleaning of the accumulators and a change of batteries It is a more economical solution

When using heat accumulators, we will have to plan for the amount of energy we will need. We will have to calculate different factors such as the space to be heated at home, our contracted electricity rate, if we want more or less temperature… That is why when buying a storage battery, we have to look at some points.

The first thing is to determine the power we are going to need. Just as for an air conditioner it is necessary to calculate the necessary cold temperatures, when buying a heat accumulator it is necessary to check that it has sufficient power and that it adapts to the meters to be heated so as not to break down. but also so that he does not exceed the power.

A wide variety of aspects influence the task, such as the degree of thermal insulation of the chimney, its location and its type (whether it is an apartment, a detached house, a semi-detached… ), the orientation, the climate of the area … In fact, the manufacturers They usually provide a tool for this purpose through tables like the one from Ducasa above or with a calculator like this one from Elnur Gabarron.

In addition to the type, whether they are dynamic or static, it is interesting that they have a thermostat to better regulate the temperature in the room. If we also want to integrate it into the smart home, we will have to monitor the connectivity that they offer and that they have an application to configure the various parameters of the mobile (including the possibility of adapting to the electricity tariff ) as well as the ability to control them remotely.

Recommended models

When it comes to opting for a heat accumulator, we do not find such an abundant offer as we find when we talk about conventional radiators. However, there are some models on the market that we can consider.

From the ELNUR brand, there are, for example, accumulators that range from 359 euros for the ELNUR Ecombi 15 to 649 euros for the ELNUR Ecombi 40, a solar model. The difference is in the ability to generate heat that it offers.

DUCASA is another of the brands that offers heat accumulators. It is a model with versions of 850W for (429 euros), 1700W for (529 euros) or 2550W for (629 euros). These accumulators can be controlled from the mobile, they have an ambient temperature sensor and have a charging time of 8 hours.

The same firm also offers static heat accumulators available in versions of 480W for (429 euros), 950W for (529 euros), 1,900W for (699 euros). These have a charging time of 14 hours and have a simple sensor charging thermostat that allows the user to decide the charge level according to their needs and the winter season.

Another more complete model is this one, it offers temperature dosing control, temperature sensor and overheating protection. They are available in versions of 2000W at (849 euros), 3000W at (999 euros) 4000W at (1149 euros), 5000W at (1299 euros) and 6000W at (1449 euros).
