As the chill of winter sets in, consumers are starting to think about their heating plans for the season. Nowadays, there are numerous heating devices available in the market, including traditional options like air conditioners and radiators, as well as newer methods such as underfloor heating and hydronic systems. Among these, hydronic heating stands out for its energy efficiency and affordability. Let’s hear what the experts have to say.
New Heating Methods: Comfortable and Eco-friendly
Hydronic HVAC, a concept that has recently gained traction in the heating market, refers to integrated systems that include heating, cooling, ventilation, and indoor air quality management. Dong Chongcheng, deputy director of the China Heating Radiator Committee, notes that as the heating market evolves, so do the methods of heating. Beyond conventional air conditioning, radiators, and centralized heating in northern regions, new techniques like underfloor heating and geothermal heat pumps have become popular.
Compared to traditional heating methods, hydronic HVAC requires a higher initial investment but offers greater energy efficiency, comfort, and environmental friendliness. For instance, underfloor heating not only boasts high thermal efficiency but also minimizes heat loss, leading to significant energy savings. It ensures uniform indoor surface temperatures, providing a cozy warmth without the sensation of cold feet. Additionally, underfloor heating avoids the turbulent air convection caused by radiators, resulting in cleaner indoor air. Experts suggest that given the high humidity levels in Chongqing, installing such systems can help reduce the prevalence of rheumatic and respiratory illnesses compared to traditional heating methods in colder climates.
Easy Installation, Energy Savings
Despite the many benefits of new heating technologies, the HVAC market in Chongqing lags significantly behind cities like Chengdu. This lag stems largely from consumer perceptions. Many hesitate due to concerns over cost, potential water leaks, and installation complexity.
"In reality, home HVAC systems are not extravagant," says Zhao Guozhong, technical director at Milo HVAC. "At least a third of Chongqing residents could afford such systems." For example, a typical 100-square-meter home equipped with three wall-mounted air conditioners and one cabinet unit might cost close to 20,000 yuan. Adding a hydronic or underfloor heating system would only increase the total cost by another 20,000 to 30,000 yuan. Moreover, a gas heating system eliminates the need for a separate water heater, providing consistent hot water while reducing monthly heating costs by about 30% compared to air conditioners.
Zhao Guozhong further explains that even homes that have been renovated can accommodate HVAC installations. These systems are not cutting-edge technology, and installation isn’t overly complex. For instance, a 100-square-meter house can be fitted in about five days without damaging existing decor.
Choosing the Right HVAC System
HVAC systems primarily fall into three categories: radiator systems, underfloor heating systems, and central air conditioning systems. When renovating a new home, many homeowners ponder which system to select.
Experts point out that each system has its unique pros and cons. Consumers should choose based on their living conditions, family size, and heating needs. Homes with elderly family members and young children often benefit from underfloor heating during winter. "Underfloor heating provides even and comfortable temperatures, saving energy when used consistently. Its elegant design also works well for intermittent heating when using water-based radiators." Radiators, on the other hand, offer flexibility and rapid cooling, though they occupy space.
Zhao Guozhong adds that different areas and house types suit different HVAC products. Bungalows and villas are better suited to underfloor heating, while apartment-style homes fit radiator systems. Hybrid systems—like warming the living room and heating the bedroom—are also possible.
HVAC experts advise contacting heating product providers before starting work to plan equipment placement. When purchasing, visit areas like Jiangbei Hongxing Meikailongbei Street, where many brands gather. Carefully research brands; avoid impulsive purchases just because prices seem low. Check the company's history, credentials, scale, and reputation. Ensure proper documentation and, if needed, request relevant test reports.
How to Choose HVAC
Underfloor Heating System - Slower temperature rise, ideal for continuous heating. Recommended for long-term residents in spacious homes or high-rises.
Radiant System - Faster heating, suitable for intermittent use. Ideal for daytime-unoccupied homes requiring evening and weekend heating.
Underfloor systems are typically installed during renovation. Retrofitting may damage existing decor. Radiator systems can be retrofitted but require advanced design and construction expertise.
Central Air Conditioning System - Less comfortable than other systems, costly to operate. Typically found in large malls, hotels, or upscale apartments. Only compatible with initial renovations, not retrofits.
To ensure a smooth process, always consult professionals before installation.
