Heat accumulator in the heating system: device, day-night

Nowadays, when electricity and gas are constantly becoming more expensive, it is almost impossible not to think about reducing heating costs. To this end, many people insulate homes, change boilers for more modern counterparts, or, for example, install solid fuel heaters.

However, there is another solution that will help you really save as much as possible - we are talking about heating heat accumulators. In short, it is an additional element of the system that accumulates heat during intensive work of the boiler and gives up the accumulated energy during the shutdown of the main heater.

Now let's take a look at the details.

How does the battery of this type

In fact, this is an ordinary vertical tank of cylindrical steel, inside of which there is water.

• The peculiarity is that the walls of the drive have a very good level of thermal insulation. (it can be made of special foam rubber, polystyrene foam or polyurethane foam), thanks to which the heat transfer medium inside the tank cools down very slowly.
• The hydroaccumulator for heating systems can simply be heated both from hot water, which is moving away from the boiler, and from the heating element built directly into the tank..

Note! Here there is one positive feature - in a situation when the boiler power is excessive, the energy does not go in vain, but heats the water inside the tank. Due to this property, by the way, the elements of the boiler itself last longer, since they do not overheat.

As for the principle of action, everything is very simple here - the scheme is as follows:

1. If the temperature of the water in the radiators decreases, and there is no hot water supply from the boiler itself, the circulation pumps are automatically switched on, to which the storage tank for heating is connected.
2. It turns out that the pumps react to the thermostats and after switching on they begin to pump the coolant into the line from the storage tank.

Depending on the characteristics of the tank and the system parameters - such a capacity can provide continuous supply of hot water to the system for quite a long time. The minimum is 3 hours, and the maximum can be several days.

And the trick here is that the coolant from the tank does not flow on an ongoing basis after switching on, but is periodically supplied - as soon as the signal goes that the temperature in the radiators is below the specified number. Such a heating system with a heat accumulator makes it possible to use the coolant as efficiently as possible.

How it helps to save and how it helps

In fact, everything is quite simple to understand - now see for yourself. We simulate a couple of specific situations.

Day-night mode

As you know, there are day and night periods of the boiler. In the daytime, of course, a maximum of energy is required from the boiler and it must constantly work. But for the night, you can turn it off completely and “take” the heat accumulated during the day from the tank.

Saving?

Of course, yes - because throughout the night gas and electricity will not be spent.

• That is, it turns out that the cost of heating in winter can be reduced by at least 35-40 percent!
• At 50% there will not work, because there is a small percentage of the cost of energy that goes into heating the tank.

We continue.

Long breaks in work

Suppose that you are going to go for a couple of days somewhere and at this time, naturally, you do not need to maintain maximum heat in the house.

• However, in winter, an ordinary boiler cannot be turned off - because radiators and pipes will burst, because water will freeze in them. But the heating system with heat accumulator allows such shutdowns!
• With it, you can safely turn off the boiler and drive away - the drive “take care” that the water in the main line does not turn into ice, and the normal minimum temperature in the rooms.

As you understand, the “work” time of the tank depends on many factors - on the volume figure that the hydraulic accumulator has for heating, on the area of ​​the house and, for example, on the level of its insulation. In addition, the indicator of the minimum temperature that you set.

Note! Drainage of water from the system for the period of departure is not an option. Because because of such temperature drops, the wooden elements of the house begin to deteriorate, the wooden elements of the house become deformed, the level of durability of the finishes decreases, etc.

And, of course, the thermal accumulator of water heating is very helpful in those situations when the boiler broke down, the electricity, gas, etc. were turned off.

It is worth noting such an important point as the use of storage devices in those systems that are “tied” to solid fuel boilers. After all, the instruction of operating such devices by default assumes that the coolant heats up only when the fire is burning.

If there is a probability of gas shutdown, boiler breakdown, but it is low, then the situation is quite different with firewood - they can simply simply burn out at night while you are sleeping and suddenly go out, if you do not follow them.

And the question arises - why not getting enough sleep and constantly “monitoring” such a boiler for burning or not burning? After all, you can really put your own heat storage batteries for heating and sleep peacefully - even if the flame goes out, the temperature in the rooms will still remain comfortable due to the supply of coolant from the drive.

Note! Similar tanks can be used not only for standard highways with radiators, but also for systems with water heated floors. After all, in fact, figuratively speaking - the pump no matter where to send water - to radiators or pipes. And if we are talking about a system with natural circulation, then all the same - the water in the warm floor will fall in the same way as in the radiators as long as there is a temperature difference between them and the drive.

It turns out that heat accumulators in heating systems are not even just a desirable element, but in the most direct sense a useful, indispensable and convenient device.

Let's summarize the article. It turns out that heat storage heating really should be organized for the reasons discussed in the article. And with all these advantages - the price of drives is very affordable! So there is nothing to think about - such a purchase is definitely expedient and profitable.
