5.5kW Perfect 55 Small Instant Water Heater

The Perfect 55 (P55) Instant Water Heater is a compact and powerful point-of-use hot water solution designed for installation beneath sinks and in locations where space is limited. Rated at 5.5kW, the Perfect 55 is one of the smallest instant water heaters available on the UK market, making it ideal for installations where space is at a premium such as wash basins, small sinks, offices and staff kitchens.

Manufactured in Europe to the highest standards, this award-winning instant water heater is CE approved and built for safety, reliability and energy efficiency. The unit uses simple electronic controls to regulate both water flow and temperature, helping to ensure safe operation while also prolonging the working life of the heater.

The Perfect 55 features a non-vented design, meaning it can be used with standard pressure taps without the need for specialist taps or expansion kits. It is recommended for use with taps fitted with a spray nozzle. If a spray nozzle is not fitted, the heater includes a spray adaptor compatible with most standard tap fittings.

Optional standard or push-fit flexi hoses are also available to purchase separately (stock dependent) to make installation quicker and easier.
