Clean heating equipment scrap identification

The main types of clean heating equipment are hot water air source heat pumps, hot air air source heat pumps (hot air fans), and gas wall-mounted boilers. The scrapping identification of clean heating equipment includes air source heat pumps and energy storage electric heaters that have been converted from coal to electricity for more than 10 years, and gas wall-mounted boilers that have been converted from coal to gas for more than 8 years. If they cannot be used normally and have not reached the service life, they have been deemed to meet the scrapping standards.

As an independent third-party appraisal agency under Guoke Holdings, Zhongke Testing has the qualifications for fixed asset scrapping appraisal. Based on the list of assets to be scrapped and assessed and related information provided by the client, it can organize technical personnel to evaluate the assets to be scrapped and evaluate, and issue a clean heating equipment scrapping appraisal report.

1. General scrap standards

Clean heating equipment has been in operation for 10 years or more (gas wall-mounted boilers have been in operation for 8 years or more) and cannot be used normally or has not reached the useful life but has been deemed to meet the scrap standard.

2. Scrapping standards for main equipment types

1. Technical testing and evaluation: Conduct comprehensive technical testing and evaluation of the equipment.

2. Maintenance history analysis: Thoroughly analyze and evaluate the maintenance history of the equipment, including maintenance records, replacement parts, maintenance costs, etc. in the past few years, to determine the reliability and maintenance cost of the equipment.

3. Energy efficiency assessment: Evaluate the energy efficiency of the equipment, including evaluating the equipment's energy utilization efficiency, energy consumption, and compliance with current energy efficiency standards.

4. Environmental compliance assessment: Review the environmental protection status of the equipment, including compliance with emission standards, effectiveness of pollution control facilities, etc., to ensure that the equipment will not have a negative impact on the environment during use.

was entrusted by a certain street office to conduct a technical appraisal on whether the cleaning and heating equipment of each household in the street can be scrapped.
