If your hot water system makes a lot of popping and crackling noises when it is heating up it could be due to “Kettling”. Kettling is when there is a build up of sediment in the base of the tank. We can solve this problem by performing a routine service and anode replacement, followed by a tank flush to remove the sediment. If you stay on top of this and have it done every 2-3 years, it will prolong the life of your tank.
Here are some signs that your hot water tank may need replacing:
- The hot water tank has water leaking from it.
- You have rusty or dirty looking water coming out of your taps
- The tank itself has lots of rust on it.
- The water may not be as hot as it used to be, or you may not have any hot water at all.
- The hot water system is making unusual noises
A gas storage hot water system takes roughly 30-40 minutes for a standard size.
Absolutely not, Gas storage hot water systems are very safe and they come equipped with fail safe mechanisms to shut off the gas supply if the pilot light is extinguished, and also to avoid the tank over pressurising. If you think that your hot water system is unsafe or you can smell gas, shut off the gas supply and call us immediately and one of our friendly plumbers will be at your door ASAP!
