⭐ Key Features of Usha QH-4302
1. Dual Quartz Heating Tubes
The Usha QH-4302 features two quartz heating tubes that produce radiant warmth.
Quartz heaters provide direct heating, making them useful when you want to feel warm without waiting for the entire room's air temperature to rise.
2. Two Heating Settings
The heater provides two heating modes:
- 400W: Suitable for mild cold and lower heating requirements.
- 800W: Provides higher heat output during colder conditions.
These settings allow users to adjust power consumption according to their needs.
3. Stainless-Steel Reflector
The heater includes a rust-resistant stainless-steel reflector.
This reflector helps direct radiant heat outward toward the area in front of the appliance.
4. Tip-Over Safety Protection
The QH-4302 includes a tip-over safety mechanism designed to switch off the appliance if it falls or tilts.
However, this feature does not eliminate the need for supervision and proper placement.
5. Quiet Operation
Unlike fan heaters, the Usha QH-4302 does not rely on a blower fan.
As a result, it generally operates quietly and may be suitable for users who dislike fan noise.
6. Compact and Portable Design
The compact construction makes this heater convenient for use in smaller indoor spaces.
Always switch off the heater and allow it to cool before moving it.
⚡ Usha QH-4302 Electricity Consumption
One of the main advantages of an 800W quartz heater is its relatively low hourly electricity consumption compared with a 2000W fan heater.

| 400W | 0.4 kWh | ₹3.20 |
| 800W | 0.8 kWh | ₹6.40 |
