If it is not possible to accommodate the expansion in the existing pipe work, then it is necessary to use an Expansion vessel and no-return valve (Kit A). If the mains water pressure may exceed 3.5 bar, a pressure reducing valve (Kit B) should also be installed. The discharge from relief valve must be made in a safe and conspicuous manner; therefore a Tundish (Kit C) is available for 10 and 15 Litre units if required.


Water Heater Kit A - 2 Litre expansion vessel and non-return valve.


Water Heater Kit B - Preset 3.5 bar pressure reducing valve.


Water Heater Kit C - Discharge Tundish.
