Which is Better, Underfloor Heating or Heating Radiator?

1. Comparison of initial investment between underfloor heating and heating radiator

The consumption of low-temperature hot water floor heating main pipes and stand pipes can be reduced by 50%-60% compared with radiators, while indoor only 1-2 meters of branch pipes are used, and the radiators are changed to floor heating plastic pipes, which greatly reduces material costs. The actual cost of floor heating is about 50 yuan per building square.

2. Comparison of operating costs between underfloor heating and heating radiator

The biggest advantage of underfloor heating is to save energy.

The water supply temperature for underfloor heating is below 60℃. When the temperature drops to 15℃ in winter in the city, the water supply temperature is generally between 50-55℃. Therefore, the temperature of the water supply is low and the heat loss is small. A major feature of floor heating is to heat the room under the dual effects of radiation intensity and temperature, forming a more reasonable indoor temperature field distribution and heat radiation effect. When floor heating and radiator are at the same water supply temperature, floor heating can have 3-4℃ equivalent thermal comfort effect.

Underfloor Heating or Heating Radiator

Therefore, when the room temperature is designed with floor heating, the room temperature is 2 ℃ lower than that of ordinary radiator heating to meet the required effect of radiator heating. The water supply temperature of radiator fin heating is above 90℃, so the use of floor heating alone can save 30% of energy, thereby saving the same proportion of underfloor heating system cost. The thermal gradient of the room is high and low, which absolutely meets the physiological needs of people.

3. Comparison of maintenance costs between underfloor heating and heating radiator

The radiator of any brand will corrode during use. After several years or more than ten years of service life, the radiator and indoor branch pipes will rust and leak. They must be repaired or replaced every heating season. The maintenance costs are relatively high, which increases the economic burden on the residents and developers.
