On the left of the first pic is the R22 I’ve had for some years and on the right one I recently bought in auction. Slight differences to be seen in the front opening and burners but height and width are similar. See four screwholes at the back of the one on the right. Top screwhole bottom screwhole Side view showing narrower base and angled back on the one on the right. Heater on left screws not countersunk Heater on right screws countersunk
Those back screws suggest it was intended to be fixed to something. Maybe a wall or perhaps more likely a back frame for stability. Maybe that's why Tilley increased the depth which because of the shape would lower the centre of gravity and also the extra width would make it more stable. ::Neil::
I’ve yet to actually see one of these Tilley R22s in the flesh. I know they must be around, but rare beasties they must be here in Queensland. Cheers Pete
You could have mine, Pete, except you wouldn't want to pay to ship one down under - they weigh a ton...
Thanks @Jean J , I like the use of the 'square' between the two radiators to show the different profiles. Henry.
The back screw holes may have been to mount a protective cover or screen. There would be a fair bit of heat from back of the reflector.
Could be Graham. They are set back a bit. Good info Jean. I like finding these new things about Tilleys.
Not sure I agree with that statement, admittedly it's a long time since I had my R22 lit and I can't remember how hot the body of the heater became but surely, as long as the reflector is kept clean and shiny, the heat is projected forwards. I know that this is certainly the case with my Tilley R1, R55 and BiAladdin bowlfires where I could comfortably rest my hand on the rear of the reflector, all day long if I had nothing better to do. @Anthony My own R22 is now well towards the back of the pile and not easy to get at but it's not too long since you posted your Kayen version here Kayen HR20 Radiator Can you recall your observations ? Henry.
@Henry Plews, the Kayen I had running for just enough time to get a picture of it then shut it down. Takes too long to get them clean enough to put on the shelf. The R22 I actually don't remember it getting all that hot at the back. I still can't picture what would be mounted on those holes as you need access to the control cocks and filler.
@Anthony, no worries, another two months and I'll have an excuse to dig mine out of the pile and experiment. Tilley must have had something in mind for those holes, otherwise, why go to the trouble of complicating the mould and tooling up to make a jig in order to drill and tap the holes ? Henry.
This one is very square in the corners. Only 2 screw holes rather than 6. I have seen this in a lot of ads. From Bo Rymans post in the reference library. Dated 1934
I have this leaflet too also dated 1934. Does this suggest that the illustration in this leaflet shows another variation (because of the number of screws on the front) and that Jim Dick’s book actually show a later model?
@Jean J, in a word, no. I assume something I considered more important cropped-up and I forgot about it. The heater is now in storage away from home and I'll need a good excuse to warrant travelling the distance.
@Jean J the one I have has the trivet. I always wondered if it was an original item or from a creative owner! Alec.
Perhaps the 4 holes were for some sort of dust cover? It could have had a section cut out at the bottom or been shaped to allow access the the control taps and filler/pump?
