Choosing a solar water heater is one of the smartest investments for your home. But before buying, it’s important to know whether a pressurized or non-pressurized system is the best fit. At Moffam Electricals, we guide Kenyan families and businesses in selecting the right solar solution for their needs.
Here’s everything you need to know about pressurized vs non-pressurized solar water heaters.
What is a Pressurized Solar Water Heater?
A pressurized system connects directly to your home’s plumbing, allowing hot water to flow with the same pressure as your cold water supply.
Pros:
-
Consistent high water pressure (great for showers & modern fixtures)
-
Works well with booster pumps
-
Can support multi-story buildings
-
More durable against scaling in pipes
Cons:
-
Higher upfront cost (typically KSh 120,000 – 200,000+)
-
Requires stronger tanks and fittings
-
Slightly higher maintenance needs
What is a Non-Pressurized Solar Water Heater?
A non-pressurized system relies on gravity. The tank is placed above the outlets, and water flows naturally to taps.
Pros:
-
Affordable (from KSh 45,000 – 90,000)
-
Simple design with low maintenance
-
Energy-efficient for small homes
-
Ideal for rural or low-budget households
Cons:
-
Lower water pressure
-
Not suitable for rain showers or modern pressure fixtures
-
Best for single-story homes
Which System is Right for You?
-
Choose Pressurized if you:
Live in a multi-story home
Want modern shower systems and consistent water pressure
Don’t mind investing more upfront for comfort -
Choose Non-Pressurized if you:
Have a single-story or rural home
Want a budget-friendly system
Use basic tap and shower setups
At Moffam Electricals, we supply and install both pressurized and non-pressurized systems—ensuring you get the perfect match for your household.
