Can plastic tubes in underfloor heating withstand the heat of a steam boiler?

Can plastic tubes in underfloor heating withstand the heat of a steam boiler? Yes.

No. The floor heating design of private houses is water circulation, and the general use temperature is below 60 degrees. The steam boiler outputs steam, and the temperature is above 100 degrees. If you use a steam boiler to heat the underfloor heating, it will damage the plastic pipes of the underfloor heating.

Whether the boiler is closed or open, duplex buildings should use closed boilers. In this way, the water is replenished into the pipe through the tap water, and the water will soon be replenished into the floor heating pipe due to the effect of pressure, but it also needs to be exhausted in the water separator**. Otherwise, the circulation is not good, resulting in inconsistent heat upstairs and downstairs.

Your boiler seems to be an atmospheric boiler, right? It should be that the water of the boiler is pumped into the third floor by the circulating pump, and the first and second floors are lower than the boiler, and the pressure difference formed by the hot and cold water without the circulating pump can be circulated naturally, but the circulation speed is slower. The resistance of floor heating is greater than that of ordinary radiators, I don't understand what your pipes are going on, please add details.

On what floor is the expansion replenishment tank of the boiler? Is it that the pipes on the third floor are not opened, or is the circulating pump not open?

Is it a brain teaser?

Is the hot water pump on?

Think so.

In fact, in the domestic hot water and floor heating system, the main function of the water separator is to divide the hot water of the main road into many branches into the floor heating pipe, rather than being used to divide domestic hot water and floor heating hot water.

In this system, domestic hot water and underfloor heating hot water are mixed together, and the corresponding faucet or valve is only required to be used to use domestic hot water.

No, the casing machine uses two layers of copper pipes to heat the system water and cold water separately.

The plate replacement machine is to use the high-temperature system water to indirectly feed the cold water heating system through the plate exchange, and the machine is to use the high-temperature system water to indirectly heat the cold water of the water tank through the water tank coil.

The main function of the water separator is to divide the total floor heating water into several parts and go to the floor heating coil in different areas.

There are five interfaces in the lower part of the boiler (the order of different brands is slightly different), and the conventional ones are arranged in the order of domestic hot water, floor heating, natural gas, floor heating and domestic hot water, and the corresponding interfaces are reserved by the decoration company, HVAC company and gas company respectively on the wall.

Depending on whether you use a system furnace or a dual-purpose furnace, the system furnace is just like what was said upstairs, the dual-purpose furnace also needs to supply domestic hot water, there are two more pipes, and now the boiler, Bosch is relatively popular.

The yellow ones are the gas pipes, and there are hot and cold water pipes.

Atmospheric pressure 1 ton (household boiler is OK, less than 1 ton is OK, heating area is small.

The one with the valve in the middle is the water inlet pipe, the boiler is sure to add water, connect the tap water pipe, and each side is a group of heating pipes, which is the floor heating circulation pipe, as for the one that is the upper water, and the one is the return water, read the manual.

The pipes of the heating furnace are all heat cycled by water pumps, whether they are connected to the radiator or connected to the floor heating, they all work normally and will not affect the furnace.

The heating pipe of the heating furnace and the hot water pipe are separated, if the hot water pipe is connected to the heating pipe, it is wrong, the gas stove can not be used normally, it is impossible to form a hot water circulation heating, and the cold water can not be heated all the time!

When it comes to floor heating boilers, the current mainstream brands in the market are concentrated in foreign brands, of which foreign brands are mainly concentrated in Germany and Italy, and the quality of boilers produced in these two countries is very good.

First-line brands: Viessmann in Germany, Smith in Italy, Vaillant in Germany.

Second-tier brands: Ariston in Italy, Beretta in Germany, Bosch in Germany.

The main difference between the first-line brand and the second-line brand is in the popularity and market share, from the use effect, basically can meet the ordinary family situation, in addition to special attention is that the purchase of boilers must go to the regular dealers, the characteristics of regular dealers are generally independent brand exhibition halls, authorized distribution certificates, there are physical objects, small dealers are generally in the big dealers to get the goods, after-sales service has no guarantee.

What is the size of your home? You can choose a boiler larger than 2 times the area. In addition, the geothermal heat should not be too thick, and it should not be larger than 60mm including the geothermal pipes

When it comes to choosing the size of a boiler, local businesses generally have experience in how much area they can supply, or refer to their specifications. How large the normal heating area is to choose how large the boiler, to avoid the selection of too large or too small, too large and too small will affect the economic performance of the boiler, the best choice of heating heat load is 75 80% of the rated output power of the boiler. It is difficult to say the specific calculation, different regions, different houses are sealed and insulated, and the heat load of heating is not the same.

In terms of area, small horse-drawn carts are generally avoided.
