When your Thermann won't heat
Is the hot water switch at the board still on? Is the cold tap on the pipe into the tank open all the way? And if you're on off-peak power, has the tank simply run empty after a big night of showers and washing?

Are Thermann hot water systems any good?
Thermann is a well-known name in Australian hot water, and it's one of the brands we fit. A good system comes down to the right type and size for your home, fitted properly. Tell us about your house when you ring, and we'll say whether a Thermann makes sense for you.
How long should a Thermann hot water system last?
It depends on how it's used and looked after. Water quality, how hard the system works and whether the relief valve gets looked at all affect it. When the tank starts rusting or leaking, it's done. Until then, a failed part can often be replaced instead of the whole system.
Is it safe to keep using my Thermann if it's leaking?
A slow drip from a fitting is usually fine for now, as long as you keep an eye on it. Water pooling under the tank, or water anywhere near the switch or a power point, is different. Switch the hot water off at the board, turn off the cold tap into the tank and ring us.
Why does my hot water smell like rotten eggs?
If the smell only comes from the hot tap, it's usually starting inside the tank. It's often a reaction between the water and a part in there that's meant to stop the tank rusting. Running the hot tap for a while can clear it for a bit. If it keeps coming back, ring us and we'll check it.
Why does my Thermann run out of hot water so fast?
If it used to keep up and now it doesn't, a failing element or thermostat may only be heating part of the tank. Built-up sediment in the bottom takes up room too. If more people live in the house than when it went in, the tank may just be too small now. We'll test it and find out which.
