Hyco MS3BK 3L Black Wall Mounted Boiling Water Heater

The Hyco MS3BK is a 3 litre wall-mounted boiling water heater from the Microboil Wall range. It delivers instant boiling water for tea and coffee, with electronics that learn usage patterns and switch to sleep mode when boiling water is not needed.

It suits workplaces, staff kitchens and similar commercial settings, for new installs or as a replacement within the Microboil range. A two-way tap gives controlled cup filling or a lock-on flow for larger vessels such as cafetières.

The unit has a stainless steel tank, an incoloy-sheathed 2.84 kW element, moulded EPP insulation and a durable metal case. It is designed and assembled in the UK.
