Heat exchanger
The same heat that we feel from sunlight, can be used for household needs in the suburban area — for example, for heating water for shower, dishes or watering plants. A device of this solar heater is simple. Just need the roof set so-called heat exchanger coiled hose connected to the tank with water.
Immediately it should be noted that for water heating solar heat exchanger is suitable mainly in the spring, summer and early fall (the use of this design in a cold time requires expensive, quite complex, alterations).
The proposed solution is best used for suburban areas not connected to the mains and has a sloping roof (Fig.1). The basis of design — tubular plastic heat exchanger, Packed in a box with dimensions 2×1 m. Its own one-time capacity of approximately 20 liters. Naturally, this is not enough, so you must mount and connect the tank, which will refill the system with water as it is warming up and use.
For water treatment there are many different devices. In Russia we have a traditional of them is bath, bathtub, shower. The people noticed that the bath treats, bath — relaxing, but invigorating shower. Besides, a shower is the most rapid form of bathing, which does not require any special preparations. In my view, it (the shower) and the most economical of these. Here I am, having a bath in the garden tub and in the house he decided to shower and use the tub as a sump. But the tub was already old, and on “family Council” decided that this version of us is not so necessary. Just need one soul, arranging him in the bath — in the corner of the boiler house extension to the house, where there was a gas boiler. It’s warm even in the bitter Siberian winter, besides eating and sanitation.
Thrifty when the owner erected a cottage or manor house, then after (and maybe during) a desire to build bath. It happened to me. First of all analysed the options for baths, which I had to bathe or just to see them. Remembered what I liked and what not. And read all the available literature on the subject. Whatever you say, and the main “bath” is a furnace, so the “dance” started for her — decided on its design and location in the bath. With the wall material of the questions was not clearly wood: a log or lumber, and of such thickness that could make bathing even in winter when they are particularly pleasant and helpful.
Building a country house, we try to protect it from the damaging effects of fire: use heat-resistant materials, buy fire extinguishers, installed fire alarm. But the protection from lightning often forget.
The tinkerers are often faced with the need to forge some tools or household items. A temporary forge is easy to make from scrap vehicles. Enough six refractory bricks, blowtorch and improvised grates, made of steel strips with a thickness of 3-4 mm. In a fire-proof place folded, as shown in figure 1, the horn of bricks. On the bottom put two trimming water pipes, and on these bars, so that between it and the bottom bricks there is a gap. The grate is transverse slats of the grille is a little bent, so they seized the flame of a blowtorch and sent up.
