In this guide, we’ll compare electric vs. solar water heaters to help you make an informed decision for your Nairobi home.
Understanding Electric and Solar Water Heaters
Electric Water Heaters
Electric water heaters use electricity to heat water, typically through an immersed heating element. These systems are available in storage tank or instant water heater models.
Pros:
✔ Easy to install – Requires minimal setup.
✔ Works in all weather conditions – No reliance on sunlight.
✔ Faster heating time – Provides instant hot water.
Cons:
❌ Higher electricity costs over time.
❌ May not be eco-friendly if using non-renewable electricity.
Solar Water Heaters
Solar water heaters use solar panels to absorb sunlight and convert it into heat, which is then transferred to the water storage tank.
Pros:
✔ Saves money on electricity bills.
✔ Eco-friendly and sustainable.
✔ Long lifespan – Can last up to 20 years.
Cons:
❌ Higher upfront cost for installation.
❌ Requires sunlight, making it less effective on cloudy days.
