No hot water after a power cut
After the power has been off, an electric tank has to heat up again from cold, and that takes hours. On off-peak power, it may not start heating again until the off-peak period comes round.
Give it time before you ring. If the water is still cold the next morning, ring us.

Rinnai hot water questions
Have another question? Call 0448 984 771 – we’re happy to help.
Is Thermann or Rinnai better?
Both are well-known brands, and we fit both. Neither is the right answer for every home. It comes down to the type of system your house is set up for, how much hot water you use and your budget. Tell us what you've got now and we'll help you weigh it up.
Do you repair Rinnai hot water systems?
Yes. We work out what's gone wrong with your Rinnai and give you a price for the repair before we start. Plenty of faults are a single part. If the unit is past saving, we'll say so plainly.
Do I need to do anything to look after my Rinnai?
Not much. Most storage tank manuals ask you to ease the relief valve lever now and then, so it doesn't seize. Lift it gently, let a little water out, then lower it gently. Stand clear, because the water is hot. If water keeps running after you let go, ring us.
Why does my Rinnai tick or click while it heats?
Metal tanks and copper pipes grow a little as they warm up and shrink as they cool. That can make a ticking or clicking sound, and it's usually nothing to worry about.
Where's the cold water valve on my Rinnai?
On most storage tanks it's on the cold pipe going into the unit, near the bottom or the side, with a handle or a tap. Turn it clockwise to close it. Closing it stops more water going into the tank, which slows a leak.
What should I do while I wait for you?
If the tank is leaking or tripping, switch the hot water off at the board and turn off the cold tap on the pipe into it. Note down anything you've noticed, like noises or rusty water. That way we know what we're dealing with before we knock.
