For terrestrial solar first need to select the site, which covers the sun as long as possible, and this area should be located as close as possible to the boiler.

We must know that the farther away from home ground will be installed battery, the longer loop (ring) and the longer the flow and return lines, and hence, in turn, follows the law and the natural circulation of water: the longer the contours, the worse the water circulation, the slower heating apartments and the greater the loss of heat.

The selected site must be as low as possible the bottom of the firebox of the boiler 2. The bottom of the tank battery ground 31 should be below the bottom of the firebox 2 is not less than 90 cm, and the lower the better.

Ground battery can zaglubit in the ground, but this should not prevent the burying of the sun's rays illuminate the tank of the solar battery.

For terrestrial solar more capacity, the better (300-800 liters), because the more water, the slower it cools after sunset. In turn, the greater exposed surface area of the tank, the faster the water is heated in the tank.

Tank Battery desirable to ground height is 3-4 times the diameter of the tank of ideas as much as possible to use the sun's rays.

Fig. 10 shows the ground the battery in the section.

The figure shows that the glazing is done by hand, illuminated by the sun since the beginning of sunrise and before sunset, with osteklyayutsya sides and roof of the battery. Glazing and sides of the ceiling must be made air-tight so as not to release the heat received from the sun.

Fig. 10 shows the construction of ground-based solar batteries are round, its walls made of brick, and outside, the sides to the top, covered with earth to prevent freezing of the walls in winter.

The walls and bottom of the battery from the inside of the thermal insulation layer is processed in such a way that heat is not transmitted to the brick and concrete walls and bottom of the battery. In the center of the structure is established tank. This tank, in turn, lay round oneself with stone or brick walls up to the nozzle, which will serve as a battery of solar heat, and at sunset the accumulated heat will be transferred to the water in the tank. Thus, the clock of solar hot water will flow to the distribution of the boiler 4.

Bac terrestrial solar battery 31 is connected to the boiler pipes, flow and return lines with a diameter of 40-50 mm (the thickness of the pipe, the better the circulation). Supply pipeline from 13 upper end of the cuts at the center of the evaporator "and" the distributor 4 and the lower end of cuts to the top of the lid or the lid of the tank. Contact line from 15 to its upper end cut into the bottom of the hollow part of the firebox 2, and the lower end cuts into the bottom of the tank of the solar battery 31.

Thus forming the solar battery ground 31. The natural circulation of water in the circuit takes place from the firebox 2 down on the back line with 15 in the tank, from the tank is moving up on the serving line with 13 in the valve of the boiler 4.

In order to preserve heat, and in order not to clutter up the Yard of the territory, pipelines can be completed under the ground in a box of bricks or boards, and the flow and return pipes should be well insulated separately and packed in a box, closed the lid and covered with earth. However (and a supply line back) swathe impossible, because the hot heat served with chilled 13 will be heated in the back line with 15, while she, in turn, would cool the water in a filing with 13 ultimately disrupt the normal circulation of water in circuit.

It is also necessary to clarify that lowering the serving line with 13 of the top of the tank battery 31 down into an underground box, and then lifting it up, the distributor 4, the water circulation in the circuit will not affect - it is checked by the author in the construction of a number of heating installations.

However, if conditions permit, and not disturbed yard layout and architecture, you can pipe (served with 13 and backward from 15) lay as air, provided good insulation.

For the release of water from the tank battery ground 31, as well as served with 13 and back with 15 cuts in the bottom of the tank discharge pipe from 20 (25-32 mm in diameter) with a valve and is displayed outside the solar panel 31.

To disable the battery ground 31 of the boiler, the upper ends of the PA units are served from 13 and backward from 15 put the valve C 13 and C 15.

To supply the cold water of the solar battery 31 crashes into a water pipe with 8 with a valve. For feedback and accompanying flushing circuit the battery 31 in the opposite line of batteries from 15 cut into the tube with valves (20-25 mm). The first tube with a 23 for food and backwash, cut into the back line with 15 below the valve from 15 from street water 8. The second tube from 22 cuts below the tube with 23 in the back line with 15, to release water from the contour of the solar battery 31, with backwash of the contour of the distributor 4.

In cases where the boiler is installed inside the apartment and emitted heat prevents people, hot water from the solar battery 31 is disconnected from the boiler and switch directly to the pipes 9, supplying hot water flat. To do this, close the valve with a 13 on the serving line from 13 around the distributor 4 and there is close valve 9 and valve with a 15 on the return line near the firebox 2. Then open the valve of 1 on the crosspiece between served with 13 and received 9 in mixers 33a and 33. As a result, the water goes from the battery 31 in the pipe 9 and a jumper with 2 - through the control knee 10 so as to create natural circulation of water in the ground circuit 31 cuts additional battery jumper with 2. The upper end of the jumper crashes into the control knee 10 above valve 10 and the lower end of the jumper with 2 cuts in the back line with 15 below the valve C 15.

Thus, the circulation of water in the circuit of the solar battery 31 will operate normally. Here we must specify that the pipe P 2 is the continuation of the control knee and prevents the reverse movement of sodium and hit the cold tap 33 oxen.

However, to get hot water from the new (old) of the contour of the solar battery, you need to open a piped-water valve with 8, feeding the solar battery 31, and close the valve 9 at the water-line 9 from the distributor 4. Consequently, the contour of the solar cell will be put under the pressure of the street plumbing 8, water pumping hot water from all faucets and taps will be fine. However, water is better way to get squeezed n not put the battery under the pressure.

With this summer at the opening of switching the water faucet or tap immediately go hot, because hot water supply pipe 9 and a jumper with 2 all the time and circulates cool will not.

In the winter, when the weather is overcast, the solar battery ground 31 water cooled and water circulation in the loop stops. Because the boiler is heated in hot water distributor 4, the contour of the ground the battery to regain circulation, ie, hot water from the distributor will go to 4 served with 13 of her tank, a tank in the back of the line from 15 and further into the firebox 2. Consequently, the boiler will heat a solar panel 31 and vainly spent fuel.

To prevent this, you need to disable a solar panel 31, closing the valve with a 15 on the back of line 15 and valve with 2 on the jumper C2. Nuzhpo also close the valve 23 to a tube of cold water.

In order to maintain the hot water in the battery 31 and prevent freezing in winter, you need at night all the glass surfaces battery harbor thermal and waterproofing mats.

PEX tools to ease the foundation of PEX radiating systems

The scope of PEX over the various heat radiant systems is widening and more and more people who are belonging to the colder regions are looking for the various heat systems that can be implemented in their homes and organizations. The heating systems that are based on radiant heat are making use of the various materials that are of polymeric nature and so PEX tools are an aid to make them work and support them.

What are PEX tools and their advantages?

These tools are nothing, just devices that are coupled with the various PEX heating systems to either support them or help in creating an efficient radiant system. The various kinds of tools include the PEX crimps tools, PEX clamp, PEX clutters, PEX guns etc. All these and several others are being used so to give a better PEX heating system.

How can various PEX tools be used?

Some of the ways in which these tools can be made use of are:

  • The PEX crimp and cinch tools are compatible with the various crimp style fittings. Thus it can give a great support to these.
  • The PEX gun clip allows one to stable the tubing lying underneath their subfloor and so this is great support to subfloor heating systems. These are available in two types. They can be either pneumatic or manual.
  • The PEX cutter is one of the most advised tools that can be even purchased. This type of tool can make an even and smooth cut in the various pipes and tubing’s thus it ensures a proper connectivity between fittings and pipes.

The various PEX Tools are not only used as they are a part of PEX heating systems but they also make the task easy while setting a radiant heat system.

Free Shipping for Plumbing Supply

3-branch Brass Manifold Set for Radiant Heating

The most common material used to make fittings is brass. However, you can find fittings made from other metals and even plastic. Fittings have ridges that when crimped make a high-pressure seal.
Using the system of PEX fittings along with PEX tubing has definite advantages over metal and plastic piping. It is less expensive than rigid plastic and copper piping. It can be installed right from the spools. It requires less fittings. It last longer because it is not subject to corrosion.

PEX tubing PEX fittings

PEX fittings are used to connect the flexible polyethylene pipes used in PEX water plumbing
The flexible pipes are not made brittle by low temperatures. Polyethylene tubes are cheaper than metal pipes and are easier to install because they do not use as many fittings as metal or rigid plastic systems. Since soldering is not used with PEX systems there are no nasty fumes or the risks associated with using a torch.
PEX tubing is wrapped in spools. Because spools weigh less than cut metal or plastic pipes, they are easier to store and cost less to ship. Tubing can be unrolled from the spools with no need for coupling fittings. Installation is much quicker and cheaper when it does not involve the running of pipe.
