Six water heater brands checked against NEA's own energy-label register on 17 September 2026, with prices from Harvey Norman, COURTS and the brands' stores. Good instant heaters cost under $100 and rate 4 ticks, while many popular storage tanks rate 1 tick and cost about $200 a year to run. Climate Vouchers only cover 5-tick heaters, and only two shops in Singapore are approved to take them for water heaters.
Most people pick a heater on price and forget the running bill.
> Quick view: best buy is a 4-tick instant heater under $100; for a tank, get Mistral 15L at $239 or a 3-tick Fujioh. Many 1-tick tanks cost about $200 a year to run, and Climate Vouchers only cover heat pumps.
The best-value brand on this list covers both types. For one bathroom, the MSH303M instant heater is S$98 (was S$118) on Mayer, Mistral's official online store, and NEA's register rates it 4 ticks at 221 kWh a year, about $69 a year at the October to December 2026 tariff of 31.16 cents per kWh. If you want a tank, the MSWH150WG 15-litre is the only electric storage heater out of 278 registered models that reaches 4 ticks (UEF 0.97, 291 kWh, about $91 a year). It is S$239 (was S$389) at Harvey Norman and COURTS; Mayer lists the same price but still showed it sold out on 18 September. Its 30-litre sibling, the MSWH300WG, is 3 ticks and $299, and this is where the money is won or lost. Harvey Norman and Mayer are both out of stock on it, but COURTS sells it at $299 (was $449) as an indent order, on the same page of search results as the 1-tick MSWH30, also $299. Pick the wrong one of that pair and you pay the same money for a tank rated 1 tick at 682 kWh, roughly $213 a year, about $110 more in electricity every year. One more thing to know: Mayer's Climate Voucher offer covers Mistral fans, not its water heaters.
MSH303M instant heater S$98 (was S$118) on Mayer; MSWH150WG 15L S$239 (was S$389) at Harvey Norman. No end date published.
If you want the biggest name in HDB bathrooms, buy the instant heater. The Aures Easy is S$140 at Harvey Norman and NEA rates it 4 ticks with a UEF of 0.99, one of the highest on the register: 216 kWh, about $67 a year to run. The Aures Premium+ scores the same 0.99 and is S$241 if you want the nicer finish. Ariston's current promotion runs the other way. Buy a selected Wi-Fi storage heater between 1 September and 31 October 2026, register the warranty with code ARILUG by 15 November, and Ariston gives you cabin luggage worth $229 (collection to 15 December, up to two per household). The catch is that every participating model (Andris 3 Top Wi-Fi, Slim3 Top Wi-Fi, Andris Lux Wi-Fi, Andris2 Top Wi-Fi and Lux-D Wi-Fi) is 2 ticks on NEA's register, using 449 to 505 kWh a year, or roughly $140 to $157 a year. They cost S$409 to S$549 at Harvey Norman. Over three years that is about $220 to $270 more electricity than the Aures Easy, roughly what the $229 luggage is worth, so the gift only pays for the extra power. Also skip the 30L AN3 30 RS SIN at S$359: it is 1 tick, about $195 a year.
Free cabin luggage worth $229 with selected Wi-Fi storage heaters bought 1 Sep-31 Oct 2026; register warranty with the code by 15 Nov. Aures Easy instant heater S$140 at Harvey Norman.

The cheapest 4-tick instant heaters at the big retailers. Champs' Vela is now S$99 (was S$149) at Harvey Norman and COURTS, against S$149 on Champs' own store, and NEA rates it 4 ticks (UEF 0.94, 226 kWh), about $70 a year. For $9 more, the Auriga Core is S$108 at both (was S$149) in matte white or black, against S$149 on Champs' own store. It is slightly more efficient at 4 ticks (UEF 0.97, 219 kWh), about $68 a year, and Harvey Norman lists a 24-month warranty. Champs' newer Virgo Ace ($148 at Harvey Norman, $249 on Champs' store) is also 4 ticks, so on price alone buy the Vela or the Auriga Core. Where Champs goes wrong is its tanks. The SA15 15-litre storage heater is rated 1 tick (UEF 0.42, 664 kWh), about $207 a year, even though it sells for S$249 at Harvey Norman and COURTS and S$298 on Champs' store. The SA30 is 2 ticks and S$279 at COURTS. If you need a tank, look at Mistral or Fujioh instead.
Vela instant heater S$99 and Auriga Core S$108 (both was S$149) at Harvey Norman and COURTS; S$149 on Champs' store. No end date published.
The safest brand to buy a tank from. Fujioh is the only brand whose every registered storage heater is 3 ticks or better: the 15L FZ-SH3015 (400 kWh, about $125 a year), the slim 20L FZ-SH3520 (UEF 0.80, 354 kWh, about $110 a year) and the 30L FZ-SH3030 (364 kWh, about $113 a year). Its FZ-WH5133 and FZ-WH5033 instant heaters are all 4 ticks. Fujioh does not sell online itself; it lists authorised dealers and official Shopee and Lazada stores, and Lazada listings put the 20L at about S$298. The reason to buy now is Fujioh's extended warranty promotion for purchases from 1 April 2026 to 31 March 2027. Register within 10 days of delivery (and by 31 May 2027) and storage heaters get 2 years' full warranty, plus 3 years on the heating element and 8 years on the inner tank, against the standard 5-year tank and 1-year parts cover. Registering online adds another three months. Transport and labour charges apply to the extended part.
Extended warranty on storage heaters: 2 years full + 3 years heating element + 8 years inner tank, for purchases 1 Apr 2026-31 Mar 2027, registered within 10 days of delivery.
Valid till 31 Mar 2027
PRICE: Japanese brand KDK is now cheapest at COURTS, where the RG20AHM1 20-litre storage heater is S$269 (was S$299) as an online exclusive. Harvey Norman's markdown to S$249 has ended and it is back at S$299 there.THE TANK: it is rated 3 ticks (UEF 0.76, 376 kWh), about $117 a year. Watch the size you choose: the 30-litre RG30AHM1 (S$299 at COURTS, S$329 at Harvey Norman) drops to 2 ticks and about $151 a year, so a couple or a small family is better served by the 20L.INSTANT HEATERS: KDK's One Knob models are all 4 ticks. The TG3BL1 is S$129 at COURTS (S$139 at Harvey Norman, UEF 0.97) and the TG3AE1 is S$182 at COURTS (S$199 at Harvey Norman); it scores 0.99 and uses just 214 kWh, about $67 a year. Harvey Norman lists a 24-month warranty on the instant models.FINE PRINT: KDK has no promotion of its own and no Singapore web store, so buy through retailers and compare the two before you pay.

This is the answer to "can I use my Climate Vouchers on a water heater?" Since 1 April 2026 only 5-tick water heaters qualify, and on NEA's register on 25 October just three models are 5 ticks, all heat pumps. Two are A.O. Smith: the 150-litre HPI-40D1.0BE (UEF 1.33, 214 kWh, about $67 a year) and the 300-litre CAHP-80. The third, Rheem's 280-litre RHP280-2805 (UEF 1.01, 282 kWh, about $88 a year), is newly registered, but we found no Singapore price for it and no Rheem store on the voucher map. AOS Bath at 178 Paya Lebar Road #06-11 scans the vouchers on delivery. It is one of only two of 781 participating stores approved for water heaters; the other, Giant's Tampines WRS hypermarket, joined the map on 21 October 2026, and we could not find a 5-tick heater listed for sale there. AOS Bath says heat pumps cost $3,000 to $10,000, and it lets OCBC credit card holders split the price over 12 months (from about $250 a month for its Micro Heat Pump) on top of the vouchers. Be realistic about payback. At NEA's three-showers-a-day assumption the HPI uses about the same power as a 4-tick instant heater, so it only saves money against a storage tank (about $128 a year against a 1-tick 30L). It makes most sense for landed homes or big families running several bathrooms at once. Two cautions: AOS Bath's own Gen 1 (S$583) and Gen 6 Digital (S$804) storage heaters are rated 1 tick, and its HDB-sized Micro Heat Pump was still not on NEA's register on 25 October, so ask to see the 5-tick label on the exact model before you count on the vouchers.

Tick ratings, UEF and yearly kWh for every model come from NEA's Energy Labelling Scheme product search, which listed 270 registered water heaters on 17 September 2026. Prices were read the same day on Harvey Norman and COURTS, on the Mistral (Mayer), Champs and AOS Bath stores, and on Lazada for Fujioh, matched by model code. The Climate Voucher rule comes from the programme's water heater page (updated 18 June 2026) and the store count from the official voucher map. Yearly costs use NEA's three-showers-a-day figure at SP Group's October to December 2026 tariff of 31.16 cents per kWh, down from 34.78 cents in the July to September quarter. Every retail price was re-read on 27 September 2026, when NEA's register listed 272 water heaters and still only two at 5 ticks. By then Harvey Norman had cut KDK's range and Ariston's Aures Premium+, Champs' Vela had dropped to $99 at Harvey Norman and COURTS, and every other price was unchanged. On 12 October 2026 we re-read every price again. Harvey Norman's KDK and Aures Premium+ markdowns had ended, so KDK is now cheaper at COURTS, and COURTS had matched Harvey Norman's $239 on Mistral's 15L tank. Everything else held. On 25 October 2026 every retail price was unchanged again. NEA's register then listed 278 water heaters including a third 5-tick model, Rheem's RHP280-2805 heat pump, and the voucher map listed 781 stores, two of them approved for water heaters. COURTS' installation charges were read on 18 September. Sale prices without an end date can change, so check before you pay. Cover: product images from Mistral, Champs, A.O. Smith and KDK.
Every price on this page is for the heater alone. COURTS is the one big retailer that publishes the fitting charge, as a checkout add-on read on 18 September 2026:
That changes the sum. A 4-tick Champs Auriga Core is $178 fitted at COURTS. A 30-litre tank from the same store is $579 fitted and $679 behind a false ceiling, so the tank costs roughly $400 more to put in before it has heated a drop of water. Harvey Norman publishes no figure at all and states only that the price excludes installation and dismantling, with third-party costs separate. COURTS also offers extended cover at $45 or $90 on top.
Only a 5-tick one. Since 1 April 2026 the scheme's water heater rule is 5 ticks, and an ordinary electric heater cannot reach it because 5 ticks needs a UEF above 1.00. On NEA's register on 25 October 2026 only three models qualified, all heat pumps: A.O. Smith's HPI-40D1.0BE and CAHP-80, and Rheem's newly registered RHP280-2805. Only two of 781 participating stores are approved for water heaters: AOS Bath, and Giant's Tampines WRS hypermarket, which joined the voucher map on 21 October 2026. AOS Bath is the one we found actually selling a 5-tick model. Instant and normal storage heaters, including every Ariston, Mistral, Champs, KDK and Fujioh model, are not covered.
For a bathroom used one shower at a time, an instant heater. Almost every instant model on NEA's register is 4 ticks (one Mistral model is 2) and costs about $67 to $70 a year to run, and good ones cost $98 to $140. Choose a storage heater if you want a rain shower with strong flow, hot water at a basin or kitchen tap, or several people showering back to back. Then pick a 3-tick or 4-tick tank, such as Mistral's 15L MSWH150WG or Fujioh's 20L or 30L, because 1-tick tanks cost about $200 a year.
Look for the energy label, which shows the ticks, yearly kWh and yearly cost at 27 cents per kWh. Online, search the exact model code on NEA's Energy Labelling Scheme product search (choose Water Heater). Model names are close enough to catch people out: Mistral's MSWH300WG is 3 ticks but the MSWH30 is 1 tick, and Ariston's AN3 15 RS SIN is 2 ticks while the AN3 30 RS SIN is 1 tick.
At NEA's assumption of three showers a day and SP Group's October to December 2026 tariff of 31.16 cents per kWh (with GST): about $67 to $70 a year for a 4-tick instant heater, $91 to $117 for a 3-tick or 4-tick storage tank, and about $195 to $215 for a 1-tick tank. The label prints costs at 27 cents, so multiply the label figure by about 1.15 for today's bill. The tariff is revised every quarter, so these figures move a little each time.
None of the prices here include it. COURTS is the one big retailer that publishes the figure, as a checkout add-on: $70 to fit an instant heater with a standard shower head, $90 with a rain shower head, $280 for a storage tank and $380 where there is a false ceiling to work around. Harvey Norman quotes no number and says only that the price excludes installation and dismantling and that third-party costs apply separately. Ask whether the quote covers removing the old heater and any new piping.
