TL;DR: If you have no hot water in Christchurch, check whether it is affecting the whole property, confirm that the power or gas supply is working, and arrange help if the issue persists.

Step 1: Check if all taps are affected

Turn on hot taps in different parts of the property.

If none of them produces hot water, the issue is likely with the hot water system.

Step 2: Check your energy supply

Hot water systems rely on electricity or gas.

You can check:

• Whether power is on at the property
• Whether the gas supply is available

If the supply is interrupted, the system will not heat water.

Step 3: Check recent usage

If a large amount of hot water has been used, the system may need time to reheat.

This is common in households with high demand.

Step 4: Look for visible signs

You can check for:

• Leaks around the hot water cylinder
• Unusual noises from the system
• Changes in water pressure

These may indicate a fault.

Step 5: Avoid adjusting unfamiliar components

Hot water systems can include components that should not be adjusted without knowledge.

If you are unsure, it is best to leave them as they are.

Step 6: Arrange assistance if needed

If the issue does not resolve or you cannot identify the cause, it is worth arranging a check.

This helps restore hot water safely.

• Power or gas supply issues
