A water heater is a long-lived purchase, and the right choice depends on your household, your water pressure, and how you actually use hot water. This guide walks through instant versus storage heaters, how to size one, what a safe installation needs, the faults to expect over its life, and honest pricing. Plumbers Ghana supplies, installs and repairs water heaters across Accra, and has.
Instant (Tankless) vs Storage (Tank) — How to Choose
Instant / Tankless Heaters
An instant heater warms water as it flows, so it never runs out and stores nothing. It suits:
- Single bathrooms and point-of-use spots (one shower, one basin)
- Homes wanting wall space saved and no standing tank
- Households where hot water is used in short bursts
The trade-off: instant heaters draw a lot of power or gas in the moment, and an electric instant unit needs a circuit that can carry the load — which is exactly why the install matters (more below).
Storage / Tank Heaters
A storage heater holds a tank of hot water, ready to draw. It suits:
- Multiple bathrooms drawing at once
- Households that want a steady supply for a family in the morning
- Properties where you would rather heat on a cycle than on demand
The trade-off: it stores a fixed amount, so a big simultaneous demand can run it down, and the tank takes up space and loses some standing heat.
Sizing — Match It to the House
Getting the size right is the difference between satisfying hot water and a daily compromise.
- One bathroom, one or two people — a point-of-use instant heater, or a small storage tank, is usually right.
- Two bathrooms or a family — a storage tank sized for simultaneous use, or a higher-capacity instant unit on an adequate supply.
- Multiple bathrooms drawing together — storage capacity, or instant units placed per point of use rather than one central heater fighting demand.
The honest way to size it is on survey: we look at how many outlets draw hot water, your pressure, and your supply, and recommend the unit that fits — not the biggest one we can sell.
A Safe Install — Why It Matters More Than the Unit
A water heater is the one fixture in the house that combines water, heat and (for electric units) heavy current. A safe installation is non-negotiable:
- Correct, adequate supply for the unit’s draw — an instant electric heater on an undersized circuit is a real hazard
- A proper isolation point so the heater can be turned off independently
- Pressure and relief provision on storage units so a tank cannot over-pressurise
- Sound mounting and connections that will not leak onto a live unit
We install to the Ghana building code (GS 1207:2018) with NVTI-certified technicians. A bargain unit fitted unsafely is no bargain.
Common Faults Over Its Life
Knowing the usual faults helps you spot a problem early:
- No hot water / lukewarm only — often a failed heating element or thermostat
- Tripping power — frequently an element breaking down or a supply fault
- Leaking from the unit — a failing seal, fitting or, on storage tanks, a corroding tank
- Scale build-up — Accra’s water can scale elements over time, reducing heat and efficiency
- Slow recovery on a storage tank — element or thermostat losing performance
Many of these are a repair (element, thermostat, seal) rather than a full replacement — a good plumber tells you honestly which it is.
What It Costs — Honestly
There are two parts to the price, and we are straight about both:
- The unit is a real retail figure — you can price a heater at any plumbing or electrical retailer in Accra, and we will fit a unit you have bought or supply one at the going retail price.
- The installation is quoted on survey, because it depends on the unit, the supply, the mounting, and what is already there. No honest Ghana plumber publishes a flat install rate — so we give you a price from a look before we start, never a surprise after.
Frequently Asked Questions
Instant or storage — which is better in Ghana? Neither is universally better. Instant suits single bathrooms and space-saving; storage suits families and multiple simultaneous outlets. Size and supply decide it — which is why we recommend on survey.
Why is my water heater not heating? Most often a failed heating element or thermostat — both common, both usually a repair rather than a replacement. Tripping power often points the same way. We diagnose before recommending a new unit.
How much does it cost to install a water heater? The unit is a real retail price you can check anywhere. The installation we quote on survey, because it depends on the unit and your supply — never a flat rate pulled from the air.
