In recent years, an increasing number of homes have been constructed with floor heating systems. This trend has brought geothermal heating into our everyday lives. However, many consumers may encounter confusion when purchasing flooring for these systems. To help clarify common misunderstandings, experts from reputable associations like the Furniture Association’s Floor Committee and prominent flooring centers have provided insights into the frequently asked questions regarding geothermal heating floors.
Myth 1: All floors are suitable for underfloor heating.
When a customer inquires if the floor being sold is compatible with underfloor heating, many sales representatives confidently assure them, "There's absolutely no issue; this is a specialized underfloor heating floor." Consequently, customers mistakenly believe that all floors can be used with underfloor heating.
Expert Analysis: Underfloor heating works by warming the floor through pipes beneath it, which then radiates heat evenly throughout the room. Therefore, ordinary flooring cannot be used for underfloor heating; instead, specially designed underfloor heating floors are required. These floors must meet stringent criteria: a high-density substrate, excellent internal bonding strength, and a water absorption thickness expansion rate of 2.5% or less to prevent cracking and deformation at high temperatures. Additionally, the formaldehyde emissions must be minimal since higher temperatures increase formaldehyde release, particularly in closed indoor spaces during winter.
Misunderstanding 2: Thicker floors provide better insulation.
While the thickness of wooden flooring influences comfort underfoot, some customers assume that thicker floors will offer better insulation for underfloor heating. This misconception often leads to disappointment when their floors fail to deliver warmth in winter.
Expert Analysis: Wood is a poor conductor of heat, so when heat passes through the floor from below, significant energy is lost. Furthermore, the large temperature difference between the upper and lower surfaces can cause warping and cracking, compromising the floor’s dimensional stability. To minimize heat loss, underfloor heating floors should ideally be about 8mm thick engineered wood flooring. Additionally, when heated, moisture evaporates rapidly, making the floor prone to gaps. Experts suggest using smaller underfloor heating panels for even heat distribution.
Misunderstanding 3: Skipping the pressure test after installation.
"I thought my renovation was complete, but I didn't realize the trouble was just beginning," lamented one customer about their newly installed underfloor heating system. After finishing the initial floor heating setup, the customer requested a pressure test from the contractor, who insisted there were no issues. However, come winter, a noticeable leak was discovered in the geothermal piping.
Expert Analysis: Before laying the final floor, homeowners should always conduct a pressure test to ensure the geothermal system functions correctly. Neglecting this step can lead to significant future problems. After filling the pipes with water and pressurizing them to the specified level, the system should be monitored for over 30 minutes for leaks. A vent valve on the geothermal manifold indicates no leaks if unscrewed. If unsure, request a retest by the plumber when changing the water supply.
Misunderstanding 4: Skipping post-flooring environmental inspection.
To move into their new home sooner, some customers rush the construction process. Once the flooring is installed, they may skip environmental testing, assuming it’s unnecessary.
Expert Analysis: Since underfloor heating floors are often composite, they can emit formaldehyde. Heating exacerbates this emission, potentially exceeding safe levels. Therefore, after installing and heating the floor, it’s crucial to verify that formaldehyde emissions comply with standards (1.5 mg/L). This ensures the safety and well-being of the homeowner.
Myth 5: Placing furniture without legs on the floor.
"It’s been less than half a year since my renovation, yet the floor in my bedroom is already warped," said a puzzled customer. Upon investigation, they learned it was due to a bed without legs, which blocked airflow beneath it.
Expert Analysis: When using underfloor heating, avoid placing furniture without legs or fixed decorative elements on the floor. Underfloor heating creates a cooling surface where warm air circulates upward. Blocking this circulation with legless furniture reduces the heat’s effectiveness and prevents proper dissipation, leading to trapped heat under the floor and potential warping.
Solenoid Pump is a type of fluid transfer device that uses a solenoid to create a magnetic field that moves a plunger or diaphragm to pump fluids.DYX has both DC solenoid pump and AC Solenoid Pump.
The main difference between DC solenoid pump and AC solenoid pump is the power source they use. DC solenoid pumps run on direct current, while AC solenoid pumps run on alternating current.
DC solenoid pumps are commonly used in applications where a low voltage power source is available, such as in battery-operated equipment or vehicles. They are also known for their efficient operation and ability to provide consistent flow rates.
AC solenoid pumps, on the other hand, are typically used in applications where a higher voltage power source is available, such as in industrial settings. They are known for their ability to handle high flow rates and provide reliable performance over long periods of time.
Overall, the choice between a DC solenoid pump and an AC solenoid pump will depend on the specific application and power source available.
