1. History of Storage Heaters in Singapore
Rheem pioneered storage heaters in Singapore, introducing models like the 85VP and 65SVP series over 25 years ago. Ariston entered the market in the early 2000s through distributor Casa Holdings, revolutionising the industry with its compact 15L square tanks. These units became popular for upgrading from bulky instant heaters, particularly in HDBs. By 2018, Ariston transitioned to direct distribution under Ariston Singapore, solidifying its market presence.
2. Comparison Parameters
To determine the best Ariston heater for your HDB, consider:
- Fitment (installation compatibility)
- Tank material
- Drainpipe connection type
- Heating element durability
- Heating speed
- Maximum temperature
3. Fitment for HDB Types
Key considerations: Ceiling-mounted units offer flexibility, while wall-mounted designs depend on beam height and pipe alignment.

Note: Discontinued models may require checking retailer stock.
4. Tank Material
Most Ariston heaters use enamel-coated iron tanks, reliant on sacrificial anode rods for corrosion protection. These require anode replacement every 5–7 years. The PRO 1 R INNOX SLIM 30 OR 40 H stands out with a stainless-steel inner tank, offering superior longevity without anode dependency even though it has one to protect.
5. Drainpipe Connection
8mm Rubber Hose: Cost-effective but prone to dislodging (e.g., SLIM2 LUX-D WI-FI).
½” Threaded Pipe: Durable, rigid connection (e.g., PRO RS J series).
Recommendation: Opt for threaded pipes for long-term reliability.
6. Heating Element Durability
Elements are sheathed in:
- Copper: Least durable; may cause circuit tripping.
- Stainless Steel: Balanced performance.
- Titanium: Lifetime warranty (e.g., SLIM2 LUX-D WI-FI).
Pros and Cons
| Heating Element | Pros | Cons |
|---|---|---|
| Titanium |
|
|
| Stainless Steel |
|
|
| Copper |

7. Heating Speed
- Fastest (3.3kW): PRO RS J and PRO R S series.
- Slowest (1.5kW): Square-tank models (e.g., ANDRIS LUX WI-FI 30).
8. Maximum Temperature
- 80°C: Ideal for heavy-duty use (e.g., SLIM2 LUX-D WI-FI).
- 65°C: PRO R S series; still exceeds competitors’ 60°C standards.
9. Top Recommendation: PRO RS J 25, 35 OR 50
Pros:
- Ceiling-mounted flexibility.
- 3.3kW heating speed.
- Stainless-steel heating element.
- 8-bar pressure rating (highest in Ariston’s lineup).
Cons:
- Minimum 25L capacity (larger than 15L models).
- No Wi-Fi connectivity.
- Iron tank (requires anode maintenance).
Conclusion
For HDB residents, the PRO RS J series excels in speed and adaptability, while the PRO 1 R INNOX offers a stainless-steel tank for durability. Always verify fitment compatibility and prioritise threaded drainpipe connections. Ariston’s blend of innovation and reliability ensures a solution for every HDB household.
