- Where is your hot water supply coming from.
- Is it electric or gas? Can you turn off these supplies safely.
- The pressure relief valve, T&PR valve is usually near the top of the heater. It should be eased quarterly, it does drip water under normal circumstances, but not constantly running.
- Turning your water heater off whilst on holidays saves electricity and gas. The unit will heat and cool for 2 weeks wasting energy & your money. Turn it on when you return, have a coffee, unpack, say hi to neighbours etc. The water will be hot before you know it
- Don’t forget to shut off the water valve. Storage heaters are under pressure. My brother in law had his water heater burst, about the time he boarded a jet for the islands. After 2 weeks, the damage to carpet, floorboards, furniture, paint $$$$
- Flexible water connections on the inlet and outlet of your water heater are dangerous. Check if you have them. If you do, I strongly recommend you have them removed and have the connections redone in copper tube and brass fittings. I guarantee these flexis will rupture and if they are indoors the damage they can cause is huge.
- Rusty water coming from the unit is a sign of age and potential disaster. Don’t ignore it!

Temperature & Pressure Relief valves. Dont forget to activate them

My old heater really is a money drain. This just kick started my motivation to get it replaced. I thought it would be too expensive so I have been puttin git off, but you are so right in it being a money and energy drain as it is. Thanks, mate.
Keeping the water heater temperature low means it has to work less, which increases efficiency. It is also possible to add an overnight shutoff timer for conventional models that continuously heat water. Installing heat traps to keep heat in, insulating water pipes, and being diligent about regular maintenance also help to increase efficiency.
