Does SparkFlow install the KDK RG20AHM1 Storage Water Heater — 20L, Japan Stainless Tank?

Yes — our team can quote supply and installation together. Add it to your cart, or WhatsApp us a photo of your space, and we'll confirm the product, installation scope and any regulated trade needed before booking.

Do I need a licensed installer for a water heater?

The plumbing, mounting and electrical hookup are different scopes. Any new or altered electrical installation must be handled by an EMA Licensed Electrical Worker; gas work needs an appropriately licensed gas service worker. We confirm who is responsible for each regulated part in your quote.

How much does installation cost?

Installation is quoted per job once we know the unit and your site (ceiling type, existing wiring or plumbing, access). WhatsApp the model and site photos; we will confirm the written scope, price and available slot during operating hours.

Is it covered by warranty?

Coverage depends on the exact product and installation scope. We identify the current manufacturer terms and any SparkFlow workmanship term in the written quote; keep the invoice, model and serial number for a claim.

How do I order and pay?

Add it to your cart and we'll send the exact quote on WhatsApp, or message us directly. Pay by PayNow, bank transfer or card. We confirm stock and an installation slot before anything is locked in.

How fast is delivery and installation?

Stock, supplier lead time, delivery access and the required trade all affect timing. We confirm product availability and the installation slot before you approve the order.

Product details

The KDK RG20AHM1 is KDK's best-selling 20-litre storage water heater, built around a Made-in-Japan stainless steel tank for long-lasting durability. A 2.5kW element with energy-efficient insulation keeps a tankful of hot water ready, while a built-in earth-leakage breaker (ELB) and an IPX4 waterproof case keep it safe in a wet bathroom. Backed by a 5-year tank warranty. Electric water-heater hookup in Singapore must be done by a licensed electrical worker — SparkFlow is BCA ME05 L1 registered, so the install is by-the-book for HDB and condo and is included in our quote, not charged as a separate add-on. WhatsApp us a photo of your current heater or the install spot for a fixed supply + install price.
