ROHS Immersion Heater including cylinder. Pre-Wired with dual safety thermostats. BEAB approved. CE mark.
External immersion heaters are designed to directly heat domestic hot water (DHW) in a vented system.

Operating Instructions

A Willis Immersion heats approximately 4.5 litres of water to a high temperature every 5 minutes, so if one can decide before switching on how much water is required the pre-heating time can be calculated as follows:

  • 4.5 litres for hand-washing, baby’s bath, shaving, breakfast dishes etc. = Pre-heat for 5 minutes
  • 9 litres required for washing-up dinner dishes, medium sized clothes wash = Pre-heat for 10 minutes
  • 9–14 litres required for a shower = Pre-heat for 10/15 minutes
  • 54 litres required for a bath = Pre-heat for 1 hour

Operation

Even with the efficiency of a Willis Immersion a cylinder insulation jacket of 75mm thickness is recommended.

An extra switch and warning light in your kitchen reminding you to switch-off will save you pounds. Have a shower instead of a bath, it will save electricity, water and time.

Warning

Because the Willis Immersion is such a rapid water heater, it is not recommended for use in hard water areas.
