Ariston Storage Water Heater:

No.

From 1 April 2018, only a PUB Licensed Plumber can carry out a storage heater replacement.

No need.

Replacing with an exact same model does not ensure better fitment nor does it result in lower replacement cost.

Many of the existing heater installations DO NOT comply with PUB code especially the older ones.

Our Licensed Plumber will require to redo a whole new pipe layout, add safety devices and fittings to comply with the Code of Practice for Water Services SS636-2018 (formerly CP 48).

Yes.

For shower and basin use, choosing a 23 – 30 litres tank will be more than enough for a single bathroom.

There will be a need for an additional cut-out to the false ceiling usually about 900x1000mm and reinstate after having completed the replacement.

The ceiling shall look the same like before.

If the heater is under 5 years old, it may be feasible to replace the parts however no one is sure until an onsite assessment is made. Sometimes the thermostat may also require changing which may add up to half the cost of a new heater.

If the heater is older, the tank may have corroded badly that the heating element cannot be removed.

Not necessarily.

Firstly, the brands that have models constructed of stainless steel does not provide a longer warranty

Having a stainless-steel inner tank:

• does not stop the heating element from failing
• does not stop the water leaking from the heating element screw thread causing short circuit
