Six Misunderstandings about the Dual-supply Water-based System! Have You Fallen for Them?

2025-03-12
Nowadays, many people want to install the very popular "dual-supply system" in the market but are afraid to do so. In fact, when many homeowners are purchasing a dual-supply system, they often hear a lot of "it is said". Today, let's take stock of those "it is said" situations that water-based systems often encounter, and at the same time, provide some interpretations to help everyone better understand water-based systems and the dual-supply system.
It is said that: The dual-supply system is not suitable for home use. Actually, this statement aims to emphasize the "dominant" position of water-based systems in the public domain. For example, the world's tallest building complexes (such as the Burj Khalifa, Shanghai Tower, Taipei 101, Petronas Twin Towers, Princess Tower, etc.) all use water-based systems. Even in some regional markets, the market share of household water-based systems exceeds that of fluorine-based systems. However, during the booming real estate market in China at that time, water-based systems followed the route of emphasizing engineering projects and neglecting home decoration. Coupled with the certain difficulty in household construction and installation, water-based systems were inadvertently labeled as "for commercial use".

The water-based system says: "Who said we are not suitable for home use? We were just delayed by the golden age of real estate... The water-based systems of mainstream brands can even meet the needs of just-needed housing units of around 70 square meters. The units are very compact and can be easily installed in the designated machine positions."
It is said that: The usage cost is high and it's unaffordable. It's somewhat reasonable to say that the installation cost is high. But it's definitely irresponsible to say that the usage cost is high. The high energy efficiency of water-based systems is an undeniable fact. If you really want to know the usage cost of the dual-supply system, just ask the homeowners who are really satisfied with it.

Of course, this is based on the premise that the thermal insulation of the house and the scientific rationality of the system design and installation, etc. For those who think it's unaffordable, there may be several reasons: For cooling, there may be insufficient water flow in the indoor fan coil, insufficient power of the indoor unit, poor thermal insulation of the exterior wall, and excessive sunlight radiation; for heating, there may be insufficient heat dissipation area of the pipeline, unreasonable pipeline layout, insufficient water flow, poor thermal insulation layer, excessive heat loss, air leakage in the building, and the use of unqualified materials, etc.
The water-based system says: Don't forget, energy efficiency and comfort are my labels!
It is said that: The water-based system makes too much noise and affects rest. If it was 7 or 8 years ago, the large noise of water-based systems was indeed a shortcoming. As we all know, times are developing, technology is advancing, and the product updates and iterations have completely solved the noise problem. Currently, mainstream brands basically adopt DC variable frequency technology and have fully carried out anti-vibration and noise reduction treatments. In the early years, most of the indoor units used AC motors, and the internal noise reduction process was relatively rough. Now, most of them use DC variable frequency motors, and with noise reduction improvements such as the design of wide fan blades, polymer volute casings, the design of motor coupling supports, and thickened sheet metal, etc., the indoor units of some brands can even achieve a noise level of about 18 decibels, which is just like the sound of a gentle breeze blowing through the leaves!
The water-based system says: I've always been very quiet now.
It is said that: There is a high risk of water leakage. Is there a risk of getting choked by fish bones when eating fish? Is there a risk of getting into a car accident when buying a car? Is there a risk when taking a plane? If you worry about this problem, then as long as you are on the earth, there are risks everywhere.

.. Well, let's not be argumentative. Let's talk about the concern of water leakage in water-based systems. Or think about why there is water leakage? In fact, it is generally caused by condensation due to non-standard thermal insulation. If it is because there are many pipeline connection points, other solutions also require pipeline connections. For example, for fluorine-based systems, if there is a leak, it will be even more dangerous. So, this is a false proposition. After using mature products, mature solutions, and standardized installation processes, there is no risk of water leakage.
The water-based system says: I'll give you a famous quote from Buffett - Risk comes from not knowing what you are doing.
It is said that: Water-based systems are easily frozen, especially in northern regions.

We say that the anti-freezing protection program of water-based air conditioners is designed for this purpose. As long as the main unit is powered on (the power consumption is negligible), the anti-freezing protection program will be activated when the temperature drops to the specified value. In addition, in cold northern regions, just like with cars, adding antifreeze is a common practice for water-based systems to prevent freezing. At the same time, it is also recommended that the power connection of the water-based system should not be connected to the main switch of the household electricity supply, but a separate control switch should be installed. This can prevent the situation where the main switch at home is turned off when you are away from home or on a long trip, resulting in the unit not working.
The water-based system says: A reliable owner won't let us get frozen, because it concerns the warmth of the whole family.
It is said that: The failure rate of water-based systems is very high, even as high as 100%.
I don't know where this rumor came from. We say that the dual-supply system is not like an electric water heater, refrigerator, or color TV that can be used just by plugging it in after purchase. It is a relatively complex system composed of a main unit, a water delivery and distribution system, an intelligent control system, and the terminal units.
Just like in the past, whenever people said the heating was not hot, they would blame the wall-mounted boiler. The water-based system feels just as aggrieved as the wall-mounted boiler. The water-based system says: As long as you choose products from regular brands, with professional design and standardized installation, how could there be any failures?
After reading the above statements, do you have a more comprehensive understanding of the water-based dual-supply system? Think about it, the comfort experienced in those globally luxurious and top-level buildings can now be enjoyed in your own small home in an instant.
