Thread: Internal boiler rust protection - potable solution needed

Hi Spin,
is there any reason that it needs to be potable?
I will ask the rep who comes in to work for you plus I think my boss is using a Rayburn so I will ask him as well (not 'til Monday though).

If no potable solution, how about something really toxic, and use a heat exchanger as well?

My understanding is they are made from Stainless Steel now. Mine is and I have seen shelves loaded with them at stores.

G'day Spin,
One option might be to season it with cooking oil similar to what you would do with a camp oven but I don't know how long this will last.
Cheers,
Greg.

The Rayburn is connected to the shower and the kitchen hot tap hence the need for potable treatment. Sometimes we fill the kettle with hot water at the sink. A heater exchanger would work of course but I have limited space and wanted to maintain capacity and for it to still fit inside at the back of the firebox of the Rayburn. I was going to do stainless but was told it could split in that application with the surface directly exposed to the fire. I have now noticed you can get stainless for other Rayburn models but I have not seen any for the older ones like the No 3. They are different size and shape boilers to the newer ones. Spin

If you ask around you might find a store that can get one made up to suit, or just arrange it yourself. I don't know what grade of stainless to use. My water jacket has been in use for over 10yrs that I know of. I don't know if it was new or used when we bought the stove. My water jacket is directly in contact with the flames at the side of the firebox.
