Let’s talk about how to heat a private house and similar issues. The author of this article decided to share her experience a little.
In my new home, the heating system finally started up yesterday. Since the season is conducive to talking about heat, heating methods and similar issues, I decided to share my experience a little.
House heating system
So, in the initial data we have:
- log house; 1st floor area – 80 sq. m, in the future – more bedrooms on the second floor (attic type); naturally, all this must be heated;
- available fuel: firewood; Naturally, there is electricity, but only bottled gas, and in the near future, the main one is not expected;
- budget: economy option.
Of course, the option of a gas boiler was dropped immediately – for objective reasons. And then the problem of a difficult choice arose. Many convinced me that I needed to buy an electric boiler, but somehow my soul was not in this idea. There are several reasons.
Firstly, in winter, electricity is periodically cut off in our area: as the snow has passed or the winds have cleared up – no, no, and it will close something somewhere. 3-4 hours, or even half a day, we sit without light. And if it’s -30 degrees outside? How is it without heating? It is clear that the water in the pipes will remain warm for some time, and we will not freeze at all. But I was reluctant to check: last winter, once there was no electricity for almost a day, then I fully appreciated the merits of the Russian stove.
The second nuance is the price of “pleasure”. Electricity becomes more expensive; even now it is not cheap to be heated with electricity, and taking into account the crisis that everyone around is scaring, there is no desire to voluntarily climb into dependence on an unstable economy. The last point in my hesitation was put by the message about the upcoming introduction of social norms of electricity consumption. And where am I going to go with my electric boiler after that ?! I’ll cure into the pipe …
Such gloomy thoughts led to the final decision: we put a solid fuel boiler. These structures run on wood, coal, pellets – in a word, on any kind of solid fuel. Moreover, sometimes they allow, without high costs for re-equipment, to switch, if necessary, to other sources of energy: gas or the same electricity. Whatever one may say, but in our forest land it is probably the best option.
No sooner said than done; the boiler is selected and purchased – it is the turn of the radiators. Previously, I did not somehow delve into their features, I only knew that radiators of the old model – cast iron – are now practically not used by anyone, because the new ones are not only more aesthetically pleasing, but also surpass their “ancestors” in terms of performance.
But it turned out that this is not all there is to know. The very first trip to the store puzzled me: it turned out that there are aluminum and bimetallic radiators. What’s the difference and which option is right for me? Thanks to the sales assistant – he explained in detail what’s what.
It turned out that bimetallic radiators are usually installed in central heating systems. There are two main reasons: aluminum can not withstand pressure testing (they are not designed for such pressure), and there is a risk of damage by chemical reagents used in such systems. But for private houses with autonomous heating, this is a great option.
The price of radiators of the same type can vary considerably, but, as they explained to me (and I readily believe it), this indicator depends solely on the manufacturer, since the operating parameters of such products are standard.
The number of radiator sections is also different. For the types that I considered, when calculating the necessary equipment, it is assumed that one section is enough to heat 2 square meters of area. By the way, when choosing a boiler, the area of the heated room (or, to be more precise, its cubic capacity) also serves as one of the main parameters: it sets the required equipment power.
In order to mount the heating system, you need pipes (PVC), all kinds of connecting elements, taps and other details, about which I will not tell anything, since, fortunately, I was not offered to delve into these difficulties). I will only say that when planning costs, you should keep in mind: all these “little things”, including chimneys, fasteners, etc., together will give an amount that is quite comparable to the cost of a middle class boiler (for reference: in our stores, the range of solid fuel boilers has a huge price range – approximately from 18 to 100 thousand rubles).
A necessary element of the system is a pump. Its task is to make water circulate in the system. This, on the one hand, provides uniform heating of all radiators in the house, and on the other hand, it does not allow the boiler to overheat. In the event of a sudden power outage, it is advisable to mount the system in such a way that there is a slope that allows water, in which case, to circulate by gravity.
I have an open system, and its indispensable attribute is an expansion tank, which is usually installed somewhere in the attic. The water level in it constantly fluctuates as the contents of pipes and radiators expand from heating. published by econet.ru
