All the best for your celebrations tonight and New Year. May it be a good one for all those travelling our wonderful country.
Advice please on something that is no doubt obvious to all but me. I have just replaced the hot water anode in the heating system and I am curious to know whether by filling one of my water tanks or by connecting to mains water will this automatically refill the hot water tank (obviously with cold water) or do I need to turn on the 12v water pump to pump water up to the hot water tank. Obviously, my concern is before igniting the gas hot water I want to ensure there is sufficient water in the tank to prevent any damage. I have changed the anode before and all has been OK but I am just not sure what the correct process should be.
Thank you in advance for any advice, and again, enjoy tonight and stay safe wherever you are.
Regards
Peter

I would suggest you should make this post in Techies Corner, as you should get a lot more response from those with the knowledge you seek.
All the best to you for the New Year...

As Aus said, you may have turned on either your pump or connected to mains to flush the tank whilst the anode was out.
Otherwise do as I do and use a hose pushed into the anode hole to flush the tank. It is amazing the crud that comes out.
I guarantee you will never fill your kettle for coffee from the hot tap again.
Now, to answer your question, you do need to completely fill the hws prior to attempting to heat it. It doesn't matter whether you use mains tap or your
pump, turn on all hot taps and run them until no more air is expelled. Don't turn them on full bore as there will be spatter lol.
Once non aerated water flows you can safely turn on the heat.
Once the tank has heated this is a good time to check the anode for leaks.

Hi Peter
On my Coromal 635 the hot water tank is filled automaticaly from A. the connected mains or B.from the tanks when the 12 volt pump is activated .Trick I have learnt of late is when I know the hot water tank is empty and I,m filling from the mains I open the pressure release valve (a tap would also do) thus letting the air excape and filling the tank completely.

I always thought one should never use hot water from HWS at home or in the van because of the chemicals. In some states HWS at home also have an anode.

If you think about it , the built up crud in the HWS is a combination of what's in the cold water, the sacrificial anode and the material the boiler is made of. It all separates because of heat and settles on the bottom of the boiler making it harder for the gas flame to heat the tank water efficientlly. A good flush out of the heater annually, will make the anode and tank life last a hell of a lot longer.
Take it from ol plumber,

Thank you for all your replies. Have flushed the tank as suggested and yes, it is surprising what came out. Some great info you have given me, much appreciated guys. Enjoy 2015.

Once you have changed the anode and connected the hose to mains to refill you must bleed the air from the tank using the bleeder valve on the tank as just opening your taps will not expel all the air.
