2000Ltrs Centralized Water Systems CSW2000 - DAYLIFF CWS – Pumped Solar Hot Water for Homes & Institutions

When your hot water system demands more than a simple tank‑on‑roof setup, the DAYLIFF CWS pumped circulation range delivers. Designed for centralised distribution where the storage tank is located remotely from the solar collectors, this system is perfect for everything from larger residential homes to schools, hotels, and hospitals.

Why the DAYLIFF CWS stands out

High‑efficiency solar collectors
The system uses Ultrasun Premium solar collectors featuring full‑area copper absorption plates ultrasonically welded to copper circulation tubes. Add advanced insulation and tempered security glass, and you get energy absorption of up to 95% — even in less‑than‑perfect sun.

Long‑life, eco‑friendly storage tank
The indirect single‑coil tank is built from low‑carbon steel with a double enamel internal coating plus cathodic protection. That means exceptional corrosion resistance. The external powder‑coated steel casing includes soft foam insulation, and thermostatically controlled heating elements (1×2kW up to 500L / 2×2kW for 1000–2000L) ensure backup power when needed.

 Smart circulation control
An advanced programmable differential temperature controller manages the forced circulation system. It takes inputs from multiple sensors, then signals the circulation pump and thermostats to optimise hot water availability. The digital display shows system layout, pump runtime, and live temperatures.

Premium pump option
Upon request, you can upgrade to a Grundfos Alpha2 25‑60 speed‑controlled circulator pump for even greater efficiency and quieter operation.

Built for real Kenyan needs

Whether you're designing hot water for a rural guest lodge, a busy hospital, or a multi‑storey residential block, DAYLIFF CWS systems come in various tank sizes and collector configurations. They deliver reliable, pumped solar hot water heating without the placement restrictions of thermosyphon systems.
