Thread: Bought a Rayburn 620 today

Took the top and back plate off it.......... yes boiler has been replaced with firebricks, all seals are fibreglass rope. Has been done professionally, except on the firebox door where it is in the wrong place to seal on the lip of the frame.

It wouldn't have kept alight overnight because of this.

Fixed a casting flaw with the pin in the lower grate, which was cone shaped and wouldn't let the rotating grate turn properly.

Had a chat with a friend who does all things stainless and I'll cut all the pieces in 316 for him to weld up, like in these 3 pics:

In my collection of 'stuff' was a 319 stainless wall mount handrail that'll be perfect for the pipes when cut in half.

Going to look for some 316 plate at the scrappies when lockdown is over. Need 1000 x 300 in 3 - 5mm if anyone has any kicking around.

The new stuff (like in those pics) looks too pretty for something like a boiler, but that's what it'll be if necessary.

cheers, DL

I think Iron Bark some times left a few coals but most of the time it was a cold start at our place as well. I do miss those tea cakes, scones and mulberry pies from it I was happy to chop the wood for all of those items

Going to have to cut some more wood in a couple of days.

Does it circulate the water under the floor just through having a header tank feed set up or is there a pump helping the circulation?

cheers, David L

There is a small pump, although there is some circulation when the pump is off, but not fast enough to prevent the jacket boiling when the fire is turned up. There are temperature switches on the hot water riser to turn on before it boils, and on the hot water system return to preferentially heat the hot water system (which also has a solar collector. The solar collector directly heats the hot water, the stove heats it via a coil of large diameter copper pipe in the tank. The circulating water in the heating system had a small header tank cistern with a float valve and cold water feed to replace loss by evaporation (system must not be sealed in case it boils! (and to allow for expansion)

Edit - spelling

My sister is off grid and her solar set up (about 7 copper tubes in glass) will boil all by itself at least half the year.

The rest of the system is designed to accommodate this but it is a bit disconcerting to hear it gurgling away in the roof cavity.

Love our Wetback Rayburn. Hot water, beautiful floor heat via hydronic system (polypipes in slab) with pump and thermostat..and a good hot cooktop and oven. For the warmer months the hot water is via an electric system fed by our panels and battery.
The house with all this ( not the solar system) was built in 1985...and very well built at that.
And the 25 acres it sits on provides the firewood😎
Apparently the water jacket was replaced with a stainless steel one about 2010.

The diagrams I have of the 'boiler' on the 510 and the 620 show the boiler only going halfway across the back of the firebox on the 620, but going the whole way across on the 510.

Parts diagram I have shows all dimensions (inc. firebox) the same for both. Boiler 7" across, 11.5 vertical.

Does yours go right across the back of the firebox?

cheers, DL

Gday DFL

Water Jacket on the 355 Supreme sits across the whole width of the firebox.
