Can geothermal heating be used in a split-level house?

The floor-to-floor heating system can be used for geothermal heating. When designing, pay attention to the height of the water separator. If the area is large, the two layers of the system can be divided into two layers!

The more geothermal system loops, the better?

Many friends mentioned a question when they came to the telephone consultation. Can you give more than a few questions? For this question, explain it specifically here, the answer is no.

First of all, mentioned in the national standard of geothermal

Article 3.6.1 The inlet and outlet of each loop heating pipe shall be connected to the sub-catch and the sump respectively. The diameter of the sub-catchment should not be less than the diameter of the total supply and return pipe, and the maximum cross-section flow rate of the sub-catch and the sump should not exceed 0.8m/s. Each branch and catcher branch loop should not be more than 8 channels!

Why shouldn’t it exceed 8 roads? Most of the homeowners’ heating pipes are 1 inch or 6 points, the pressure is about 3 kilograms, and the pressure difference is between 0.05 and 0.2 kilograms (the system mainly relies on this pressure difference to circulate) . The more loops, the more water and pressure difference is needed to ensure the circulation of the system. When the pressure difference and the water flow are constant, the more loops, the worse the cycle is. (Even some loops do not circulate, and the geothermal heat is unbalanced for the system. It is worse.)

How much weight can the geothermal system withstand?

The weight of the geothermal system ground is 2 tons / square meter. (refers to data designed and constructed in accordance with national standards)

How does geothermal choose ground materials?

The choice of the floor material for the geothermal system is very important and can also determine the room temperature. There are roughly several options to choose from:

1, high temperature type:

● All the rooms are made of floor tiles. The thermal resistance of the floor tiles is very small, and the heat dissipation effect is the best. The disadvantage is that the room is relatively cool one month before and after heating. If the heating is normal, the indoor temperature can reach 28-32 degrees;

● The kitchen and bathroom are made of floor tiles, and the other rooms are made of Korean floor (high-grade floor leather). The temperature can also reach the effect of floor tiles!

2, commonly used type: living room, kitchen, bathroom using floor tiles, bedroom floor. Such as heating normal room, the internal temperature can reach 26-28 degrees;

3, low temperature type: the bedroom, the living room uses the floor, the kitchen, the bathroom uses floor tiles,

If the heating is normal, the indoor temperature is between 18-22 degrees;

In addition, when installing the floor, pay attention to the anti-vibration layer of the floor to choose thin, the thicker the floor mat, the greater the thermal resistance, the less heat is released!

What is the spacing of the floor heating pipes?

The spacing of the floor heating pipes is different between heating conditions and room layout. The design range is between 100MM and 300MM. For example, in Shenyang, the general pipe spacing is about 200MM.
