Solar Water Heater Installation
UGX4,500,000
Description
The Solar Water Heater Installation is a turnkey service involving the supply, assembly, and integration of a system that uses solar energy to heat domestic water. This service is highly popular in Tanzania, especially among new home builders and commercial operators (e.g., hotels, hospitals) seeking to significantly reduce high electricity costs associated with conventional electric water heaters. The system captures solar radiation using collector panels and transfers the heat to a storage tank, providing continuous hot water without consuming electricity.
The cost provided below is an estimate for a complete Non-Pressurized System with a capacity of approximately 150L to 200L, which is the standard size for a medium-sized residential home (3-4 people) with multiple bathrooms. This cost covers all major components, piping, accessories, and the professional labor required for installation.
Estimated Price Range (150L – 200L Turnkey System)
The price is primarily influenced by the system type (non-pressurized vs. pressurized), the tank capacity, the collector technology, and the brand reputation.
- Estimated Price (Non-Pressurized, 150L – 200L): UGX 3,500,000 – UGX 5,500,000
The UGX 3,500,000 – UGX 4,500,000 range covers locally assembled or imported non-pressurized systems, often using Evacuated Tube Collectors (ETCs) and a gravity-fed tank. These are the most common and cost-effective for typical homes.
The UGX 4,800,000 – UGX 5,500,000 range is for higher-quality, branded non-pressurized systems or smaller Pressurized Systems (e.g., 100L). Pressurized systems, which are connected directly to the main water line, are more expensive but offer better water flow and are preferred for modern, high-end homes.

The final price covers the following integrated elements:
| Component | Description and Function |
|---|---|
| Storage Tank (Cylinder) | Insulated tank (150L to 200L) for storing the heated water. This is usually dual-purpose, incorporating an electric backup element for cloudy days. |
| Solar Collector | The energy absorption unit. Most common in Tanzania are Evacuated Tube Collectors (ETCs), which are highly efficient even in cooler weather, or less commonly, Flat Plate Collectors (FPCs). |
| Mounting Frame | Steel or aluminum frame required to securely fix the tank and collector tubes onto the roof, designed to withstand wind and corrosion. |
| Piping and Insulation | Insulated hot water pipes, copper or PEX tubing, and necessary fittings to run the hot water from the roof tank to the points of use (showers, sinks). |
| Labor and Commissioning | Professional installation costs, including connection to the main water supply, routing the pipes through the house structure, and testing the system for leaks and proper heat gain. |
Value Proposition and ROI (Return on Investment)
For a household that previously used an electric water heater, the Solar Water Heater represents a significant capital outlay but offers substantial long-term savings:
- Energy Savings: A typical electric water heater is one of the biggest energy consumers in a home. By switching to solar, households can cut their electricity bills by 20% to 40%, depending on hot water usage, allowing the system to typically pay for itself within 3 to 5 years.
- Reliability: The system provides hot water during power outages, as long as there is sunlight, offering better reliability than electric-only systems, which is a major advantage given Tanzania’s occasional power instability.
- Maintenance: Both non-pressurized and pressurized systems require minimal maintenance, usually just occasional cleaning of the collector tubes.
The 150L – 200L Solar Water Heater Installation, costing UGX 3,500,000 – UGX 5,500,000, is positioned as a key sustainable home investment in Tanzania, trading a high upfront cost for guaranteed reductions in monthly utility expenses and increased energy independence.
