Reachbay installs both storage and instant heaters across the Klang Valley. We're brand-agnostic but brand-aware — Joven, Ariston, Panasonic, Rheem, Alpha Smart, Pensonic. Each has its own mounting plate quirks, isolator preferences, and warranty conditions, and we keep a tidy notes file on the van for all of them.
Storage vs instant — quick guide
Storage tanks (typically 30 – 90 L) suit households with two or more bathrooms used in the same hour. They handle multiple back-to-back showers without a temperature dip, but draw more standby power and need annual flushing in our hard-water areas.
Instant heaters fit perfectly in single-bathroom condos and en-suites. Less standby loss, no flushing, but they don't love being asked to fill a bathtub. We'll tell you which fits your usage pattern before you commit to a brand.
What a tidy install includes
- Wall survey to confirm the mounting type — concrete, brick, plasterboard with stud, or ALC block. Each needs its own anchor system.
- Brand-correct mounting bracket with manufacturer-spec fixings.
- 20 mm or 22 mm copper or PPR cold inlet, hot outlet, and pressure relief drain run to a safe terminal.
- Dedicated ELCB / RCBO trip and grounding check on the existing CU.
- Stop valves on both inlet and outlet so future servicing doesn't mean a whole-house shutoff.
- First-fill, leak check, and discharge test of the pressure relief valve in your presence.
Replacement of an existing unit
Most heater replacements take 75 – 110 minutes, including draining the old tank, removing it, mounting the new one, and re-pressurising. We bring the appropriate trolley for the haul-down and dispose of the old unit responsibly through our recycling partner.
What it tends to cost
Instant heater installation (homeowner-supplied unit): RM220 – RM320. Storage heater installation: RM420 – RM680 depending on size and bracket complexity. Add-ons like a dedicated RCBO, water filter, or thermostatic mixing valve are itemised separately on the quote.
About water heaters
Can you install a heater I bought online?
Yes, and most of our installs are exactly that. We check the box contents and the warranty conditions before we begin — some brands void warranty if a non-authorised installer is used; we'll flag that up front.
What size storage tank do I need?
Quick rule: 30 – 40 L for a single bathroom of 1–2 users, 60 L for two bathrooms, 90 L for larger landed homes with three or more simultaneous showers. We'll ask about your real morning routine before recommending.
How often does a storage heater need flushing?
Yearly in central KL, every 18 months in the outer Klang Valley where the water is a touch softer. Skipping it is the leading reason warranties get refused.
