Water heaters can be placed anywhere around your home. It is up to the homeowner to decide where to install the water heater.

As for instant water heaters, they are compact and can be installed almost anywhere near a water source and electric powerpoint.

FAQs
Common reasons for a water heater replacement are when it does not produce hot water when it trips the power when switched on when the heater is leaking or if the water from the heater is discoloured or has an odour.
- Rusty water – When rusty water appears, it is caused by rusting in your water heater or a rusty pipe.
- Water surrounding heater – The metal in the heater tank expands when it heats up, allowing fracture and a tiny leakage to happen.
- Rumbling sound – A sediment buildup happens at the bottom tank of the water heater over time and hardens each time it heats up, causing the banging or rumbling noise to emanate from the heater.
- Burn marks – Burn marks on your water heater’s bottom could suggest two possible issues – improper venting and damaged flue pipes. These are huge signs that your water heater is failing and about time you get a replacement.
A water heater should be replaced if it faces a recurring problem, if the damage is too severe, or if the water heater is old enough.
- Location – Whether a plaster or drywall, it is important to look out for the area where you want the water heater installed.
- Water supply route – Water is supplied to the water heater, and either used immediately or stored depending on the water heater. Instant water heaters require you to route the pipes supplying water to it and ensure the instant hot water heater pipe leads straight to the inlet, while the water pipe supplying your home is attached to the outlet.
- Ensure proper clearance – When installing storage water heaters, there should be a minimum of 15cm clearance on the perimeter of the water heater, and place it away from any flammable material.
- Test it out – Do not start up the electricity lines, but only the water valves. Open the faucets in your home to get water running from the model for 1 – 2 minutes and shut the valves off. Get the inline filter off, and remove any debris you find. Test the appliance to ensure that it is properly functioning.
