Clean heating is vital to people’s livelihood as well as the environment. The new heating equipments such as air source heat pumps, ground source heat pumps, and “solar thermal + biomass” guarantee farmers a warm and clean winter. The activity of “Clean Heating Interview” was launched by the Clean Heating Office of Qinhuangdao City on Nov 4, to witness the changes of the people’s lives in rural areas brought about by clean heating.
Air source heat pump: Subsidies for equipment installation, preferential price for electricity bill
“In the past, we burnt coal for heating and cooking, it was really a mess, and we use the air source heat pump this year, with subsidies from the government, which saves money and makes our home warmer and cleaner.” said Guo Lianying, a villager of Shangying Village, Donggang Township, Haigang District, when interviewed at 10 am, “It is really warm, isn’t it?”

In previous years, the villagers in Shangying Village burnt coal for heating. The renovation project was conducted by Donggang Township, Haigang District in 2020, to install the air source heat pump for 456 households in the village. At present, the commissioning and trial operation of the equipment have been completed.
“The air source heat pump has the advantages of clean environment, safety and efficiency, and the villagers are satisfied with it. We have also coordinated with the electric power department to lower the electricity price charging, so that villagers can really enjoy the equipment.” said Guo Jingwei, a staff member of the Agricultural and Rural Service Center of Donggang Township.
A total of 12,215 households in Haigang District will install the clean heating equipment, including 1,273 solar thermal + biomass, 8,486 air source heat pumps, and 2,456 thermal central heating. At present, the transformation has been basically completed, and some are under commissioning and trial operation.
“Solar thermal + Biomass”: Adjustable temperature, affordable charge
At about 11 am, the staff members were debugging and igniting the biomass heater for Wang Lichen in Li Village, Tuanlin Management Area in Beidaihe New District. The stove automatically ignites when they put the long granular biomass into it, and there is no smoke or smell during the whole combustion process.

“Compared with coal-burning stoves, biomass heaters have functions of automatic ignition and shutdown, the fuel can be fully burned, and the heat is emitted more evenly.” The staff said.

This “solar thermal + biomass” clean heating is new, with the equipment composing of solar collector pipes and a fully automated biomass heater. When the sun is strong, the temperature of the water storage tank can be as high as 80 ℃, which can be used for house heating; when the heat in the water storage tank is insufficient on a cloudy day or at night, the biomass heater will automatically ignite for heating. Users can set the heating output according to the heating area by adjusting the boilers’ power.
“Now we only spend 1,300 yuan for heating, cheaper than burning coal. It is convenient and gets warm in 15 minutes, and we can adjust the temperature as we wish.” Wang Lichen rejoiced.
The clean heating renovation in Beidaihe New District of Qinhuangdao City adopts the model of “solar thermal + biomass”, which has been completed in 5,380 households of 14 villages.
The Clean Heating Office of Beidaihe New District has issued directions of the “solar thermal+" equipment, organized on-site training, instructing villagers to use the equipment and alarm, and visiting the elderly for instruction.
Convert coal to natural gas: Gas pipelines enter the village for heating and cooking
The grey natural gas equipment haven been installed in front of the houses of Zhangguanzhuang Village, Getiaogang Township, Changli County, which converts coal to natural gas as the city people do.
“It is easy to operate, safe with alarm, and the temperature is adjustable.” said Yi Huijuan,” We have the gas stove installed, which is good for cooking. I won’t burn coal anymore.”

Du Daming, secretary of the Party Committee of Getiaogang Township, said, “We broadcast the instructions on the safe use of natural gas, and regularly visit every household for guidance, to ensure the safety of the natural gas.”
In accordance with the local conditions of electricity and natural gas, Changli County adopts the solar thermal+, the ground source heat pump, the natural gas heater, and central heating, to renovate the clean heating methods.
In order to stimulate the masses, Changli County has strengthened the policy support, offering subsidies for villagers, they can have the ground source heat pump and natural gas heater installed with 1,300 yuan, and solar thermal+ with 1,000 yuan only, and free of charge for the impoverished villagers.
The water heating blankets are provided for the households using the ground source heat pumps and natural gas heaters, so that the villagers can sleep on the hot “Kang”.
Up to now, the clean heating transformation of 138,248 rural households in Qinhuangdao City has been completed with the natural gas heaters, ground source heat pumps, air source heat pumps, solar thermal + biomass, central heating, and clean coal, including 12,215 households in Haigang District, 12,205 in Shanhaiguan District, 299 in Beidaihe District, 14,618 households in the Development Zone, 5380 in Beidaihe New District, 11,278 in Funing District, 42,383 in Changli County, 27,200 in Lulong County , and 12,670 in Qinglong.
