Hot water is something we all take for granted — until it runs out. Whether you're building a new home, renovating, or upgrading an outdated system, choosing the right water heater is a crucial decision that affects your comfort, energy bills, and long-term reliability.
At Aizo, we offer a range of high-quality water heating solutions designed to suit every type of property and usage. Here’s what you need to know to make an informed choice.
1. Know Your Needs
Before choosing a water heater, consider:
-
Property Type: Is it a flat, detached house, multi-unit building, or commercial space?
-
Number of People/Bathrooms: The more simultaneous hot water demand, the larger the system needs to be.
-
Usage Patterns: Do you use hot water throughout the day, or mostly in short bursts (e.g. mornings/evenings)?
-
Space Availability: Do you have room for a large cylinder, or do you need a compact or wall-mounted solution?
Understanding your hot water usage helps us recommend the most efficient and cost-effective system.
2. Understand the Types of Water Heaters
There are several types of water heaters, each with their own advantages:
Electric Water Heaters
-
Ideal for smaller households or where gas isn't available
-
Easy to install and maintain
-
Can be used with off-peak tariffs for lower energy bills
Indirect Cylinders / Storage Tanks
-
Often used with electric boilers, heat pumps, or solar panels
-
Suitable for medium to large households
-
Store hot water for consistent availability
Instantaneous (Tankless) Water Heaters
-
Heat water on demand
-
Space-saving and energy-efficient
-
Best for properties with low to moderate hot water demand
Solar-Compatible Water Heaters
-
Work in combination with solar thermal or PV systems
-
Reduce running costs and carbon emissions
-
Ideal for eco-conscious homes or off-grid setups
3. Size Matters: Choose the Right Capacity
Getting the size right is crucial. Too small, and you run out of hot water. Too large, and you waste energy heating more water than you need.
Use this quick guide:
| Household Size | Bathrooms | Recommended Capacity |
|---|---|---|
| 1–2 people | 1 | 50–100 litres |
| 3–4 people | 1–2 | 150–200 litres |
| 5+ people | 2+ | 250+ litres |

4. Think About Energy Efficiency
With energy prices rising, efficiency is more important than ever. Look for:
-
Well-insulated tanks to reduce heat loss
-
Timers and thermostats for control
-
Compatibility with solar energy or heat pumps
-
Models with ERP energy ratings (A+ or higher where possible)
All Aizo systems are selected with efficiency, durability, and performance in mind.
