1, system installation:
Plumbing system: The coil is divided into three parts: water collector and boiler. The installation is difficult. There is system maintenance. It takes 2 people and 2 days for 100 square meters. (coil one day, backfill one day) coil + water separator + wall hanging furnace.
Heating cable: easy to install, disk + thermostat. 100 square meters requires 4 people for 2 days.
Carbon crystal material: easy to install, carbon crystal plate + thermostat. 100 square meters for 2 people for 1 day.
2, heating effect:
Plumbing system: Preheating time is more than 3 hours, the ground is evenly mixed for at least 4 hours, and the temperature difference between cold hot spots is 10 °C.
Heating cable: preheating time 2-3 hours, soaking time 4 hours, cold spot temperature difference 10 °C
Carbon crystal material: Preheating time is less than 40 minutes, and the surface is evenly heated. The temperature difference between cold and hot spots is 5 °C.
3, related supplies:
Plumbing system: Since the temperature inside the water pipe is above 55 °C, the thickness of the ground concrete will be cracked below 3 cm, and at least the cement cost of 12-15 yuan/m2 will be increased.
Heating cable: The temperature of the cable is above 65 °C, the thickness of the concrete on the ground is at least 5, and the steel mesh is required to be added, at least the cement cost of 12-15 yuan/m2 is added.
Carbon crystal material: Since the surface heat is about 40 °C, the ground concrete can be 2-3cm, and there is no need to install wire mesh and other auxiliary materials.
4, layer height impact:
Plumbing system: insulation layer 2cm + coil 2cm + concrete layer 3cm = 7cm
Heating cable: insulation layer 2cm + concrete layer 2cm = 4cm
Carbon crystal material: paving marble: insulation layer 2cm + concrete layer 2cm = 4cm
Flooring: insulation 2cm
5. Use energy consumption:
Plumbing system: Although the calorific value of natural gas is higher than electricity, due to the great heat loss of the boiler itself, the actual energy consumption of the plumbing is very high: 1. The exhaust gas of the exhaust pipe at 120 °C-200 °C when the boiler is burning Take away a lot of heat; 2. The minimum combustion threshold of the heating boiler is 50%. When you use a water separator to heat the 100 square meter room with only 10 square meters, the combustion value is still 50%. Experience value: 100 square meters per month below 800 (Central Plains region).
Heating cable: The inherent line loss rate of the heating cable is hard to be lower than 20%. In addition to the loss of the system and the heat absorbed by the concrete layer thickened to prevent cracking, the actual electro-thermal conversion rate is hard to be higher than that in use. 70%. Experience value: Room of 100 square meters is more than 1,500 yuan per month (example in Shanghai area).
Carbon crystal material: The material with the highest electro-thermal conversion efficiency.
1. Non-metallic, large area, so almost wireless damage (width is 180 times that of heating cable)
2. 40 ° C low temperature large area uniform heat deceleration less ground heat transfer loss
3. The surface layer is 2cm, which reduces the heat storage loss. Experience value: The monthly electricity fee for a room of 100 square meters is less than 700 yuan.
6, system life:
Plumbing system: 50-50 years of underground coil 50-50 years, copper sub-collector for 8 years, there is system leakage to maintain the overall life of the boiler for more than 15 years, the main components of the boiler maintenance (own expense) 2-5 years must be cleaned and repaired System to eliminate scale.
Heating cable: underground heating cable 30-50 years within 10 years of cable outer sheath layer aging phenomenon, heat loss increase temperature controller 3-8 years (domestic, imported)
Carbon crystal material: underground carbon crystal plate life of more than 50 years without any aging phenomenon (special resin layer can withstand sulfuric acid corrosion for 15 years) thermostat 3-8 years (domestic, imported)
