FAQ
Q: How long is the water tank coil, is the longer the better?
A: Generally, 100L-30m, 150L-38m, 200L-38m, 300L-45m.
The coils of the tank and the unit must be matched, too long or too short is not conducive to heating,.
Generally speaking, longer tank coils will heat the water in the tank more quickly as they provide a larger heating surface area. This may be an important consideration for users who require large amounts of hot water. However, longer tank coils also require more space to install, which can cause problems in some space-constrained environments.
Additionally, the length of the tank coils affects the efficiency of the tank. Longer coils may mean more heat loss because they require longer pipes to transport the heat, which can lead to wasted energy. Shorter coils, on the other hand, may deliver heat to the tank more efficiently, reducing energy consumption. Therefore, when choosing a tank coil, users need to carefully weigh factors such as heating speed, space constraints and energy efficiency.
