What's BTU mean?
British Thermal Units or BTU
Fan CoilBTU represents the cooling capacity. A higher BTU value indicates higher cooling capacity. Though BTU is the most common unit, the cooling capacity can sometimes be expressed as Kilowatt (KW) or Horsepower (HP). 1 kW is about 3412BTU. 1HP is about 9000BTU. Why is BTU important to the selection of aircon for installation?
BTU is associated with Fan Coil (shown in the picture above). A bigger room needs a higher cooling capacity Fan Coil and conversely a smaller room needs a smaller cooling capacity Fan Coil. So what is the right cooling capacity or BTU for one HDB room?
The cooling capacity of Fan Coil usually comes in 9,000BTU (2.5 kW or 1HP), 12,000BTU (3.5kW or 1.5 HP), 18,000BTU (5kW or 2HP) and 24,000BTU (7kW or 2.5 HP). A typical HDB room only requires a Fan Coil with cooling capacity of 9,000BTU. If it is a larger room like the master bedroom, a 12,000BTU Fan Coil should be sufficient. 18,000BTU and 24,000BTU Fan Coil are usually used for larger area like living room or area where rapid cooling is required (e.g kitchen where cooking heat is generated).
