Relaxultra SWR-RU Shower
The Relaxultra SWR-RU Instant Shower utilizes a high-capacity 5.5kW heating element to provide immediate thermal regulation for domestic or commercial plumbing systems. This unit eliminates the need for external water storage tanks by heating water directly at the point of discharge. The internal architecture features a high-conductivity copper heating element for efficient energy transfer. A mechanical pressure switch governs the activation of the heating circuit. This switch ensures the device only operates when it senses sufficient water flow. This safety mechanism prevents dry-firing and extends the lifespan of the internal components. The chassis consists of high-impact thermoplastic that resists corrosion and chemical degradation. This material maintains structural integrity in high-temperature environments. The unit operates on a standard 220-240V AC electrical supply. It requires a dedicated 30A circuit breaker for safe operation.

Hii shower iko sawa kabisa. The 5.5kW power is no joke, especially during these cold Nairobi mornings in July. Water gets hot almost immediately. Very satisfied with the Relaxultra SWR-RU, it’s a major upgrade from my previous 3kW heater which used to struggle.

Delivery was fast to Kericho and the packaging was secure. The SWR-RU feels like a premium unit compared to the cheap plastic ones found in most hardware shops. My fundi fixed it quickly and the heat levels are very consistent.

I bought this for my rental apartments in Ruiru. The build quality of the Relaxultra is solid and the 5.5kW rating means tenants don’t complain about lukewarm water when pressure is high. It handles the continuous use well without the casing getting too hot.

Good heater but just a heads up for those with very low pressure tanks—you might need a pump to get the best out of this 5.5kW unit. Once the pressure is right, the heat is excellent. It draws a bit of current so ensure your wiring is 4mm and you have a proper 32A breaker.

The Relaxultra SWR-RU is worth every cent. I don’t have to wait for the solar heater anymore when it’s cloudy. It looks neat in the bathroom and the shower head spray is quite wide and comfortable. Definitely better than the generic brands.
