Identifying the Need for a New Water Heater
After learning what a water heater does, it’s time to check if you need a new one. Look for signs like rusted water, odd noises, or leaks. These indicate that the tank might be breaking down inside.
Age is also key; most heaters last 8-12 years. If yours is older, it may be time for a change.
Check your hot water supply often. If it runs out fast or isn’t as warm, your heater could be failing. A rusty valve or inlet also suggests it’s time to replace your unit before bigger problems arise, such as serious leaks that can cause water damage in your home.
Considering an Upgrade to a Tankless Water Heater
Once you realise your old water heater needs replacing, think about going tankless. Tankless water heaters offer endless hot water and are more energy-efficient. They heat the water directly without the need for a storage tank, which can save on energy bills.
These units only heat water when you turn on the tap, avoiding the energy loss associated with traditional tanks that keep gallons of water warm all day.
Switching to a tankless system often means considering additional installation requirements. You might face higher upfront costs due to complex electrical connections and venting systems needed for proper operation.
But despite these initial setbacks, a tankless model could be worth it since they require less space and could be mounted on a wall, offering more room in your home. Plus, their longer lifespan compared to conventional tanks can offset the early expenses over time.

Potential Mistakes to Avoid During Installation
Ensuring your DIY water heater installation is successful hinges on sidestepping common errors that could lead to inefficiency, or worse, hazardous conditions. Mindfulness of the nuances during installation can save you from costly and dangerous pitfalls.
Choosing the wrong size
Picking the right size for your water heater is crucial. A small one will have you shivering during showers when hot water runs out too quickly. On the other hand, a huge tank wastes energy and money heating water you won’t use.
This mistake can also lead to higher installation costs.
Before buying, calculate your household’s peak hour demand. Think about how many litres of hot water you need when everyone is getting ready in the morning. Check this against different heaters’ ‘first-hour rating’.
This way, you’ll get a model that fits just right without driving up your energy bills or leaving anyone cold.
Installing in a dangerous location
Just as getting the size right is essential, so too is picking a safe spot for your water heater. You must avoid placing it in locations that could put your home at risk. Do not install your water heater near flammable materials like paint or petrol.
Keep it away from busy areas where it might get bumped or knocked. Make sure there’s enough space around the heater to work on it safely.
Always check local building codes before you start the installation. Codes tell you where and how to safely install a water heater in your home. Ignoring these can lead to serious trouble, including breaking laws and putting people in danger.
If installed in an attic or other hard-to-reach place, ensure you can access it easily for maintenance and emergencies without risking injury or damage to your property. Remember that safety always comes first!
Forgetting the drip tray
Choosing the right spot for your water heater is crucial, but don’t overlook small details like the drip tray. This simple add-on sits under your unit to catch any leaks or drips. Without it, you risk water damage and costly repairs down the line.
Always place a drain pan beneath your water heater during installation.
The drip tray isn’t just an extra piece—it’s essential protection for your home. It helps prevent possible flooding and keeps moisture away from floor coverings and walls. Make sure the pan fits well and connect it to a proper drain if available.
Taking this step now can save headaches and expenses in future maintenance of your water heater.
