Stainless Boiler - 3kW Immersion elements

[SiHoltye]

Has Jim not stumped up for a range of JBK 'house' holesaws yet? Just about everyone seems to be drilling metal these days. You could rent them out Jim. I have a 22mm wood drill bit suitable for placcy bucket tap conversions, and so long as it came back, would be happy to share my £10 for one hole investment about.

There's a thought: what about doing tool loans? I have some Bosch cobalt holesaws, and if used carefully they would do lots of stainless shinies. If not used carefully then the borrower could replace them for me!

JM, I ordered 2 elements on the 16th but there was a note on the website saying that they were on holiday till the 24th so hopefully they will be now winging their way to me ask I type.

Also ordered a 100 stainless vessel yesterday for them to live in....

I'll keep you informed of any progress.

have they arrived - and if so are they as expected (i.e. have you tried them yet?)

[Garth]

nope, no sign of them, but I haven't been along to Screwfix to get some new hole saws yet, so there's no rush.

I did pick this up about 2 hours ago though.........





mmm, big and shiny

[Garth]

cheers DaaB I got a very good deal on it

it's just as well it's a 0800 number, I'd have spent a fair bit by now

I reckon Vossy would have declared himself bankrupt long ago......on phonecalls

Nah...shiny blindness saved me...I couldn't see the key pad

Nice bit of kit G...what is it ...apart from shiny

[Garth]

it's 100 litre Vos, still waiting for those elements, they might come today, post seems a bit slow round here with the bank holiday

[Vossy1]

it's 100 litre Vos

I know it's big.....and shiny ...but what is it?
It looks very well made.
What's the thing at the bottom...looks like round thing/spigot?

Just received 2 x 11" 3kw stainless steel elements from BES: £28 including overnight delivery, back nut and a couple of spare washers.

The thermostat is as Andy suggests and is easily ignored.

The only problem I can see so far, is that the "back nut" is actually BES part no. 6912 (Immersion heater ring/flange). It fits, but it doesn't have a hexagonal area to get a grip on - it's totally round.

Steve Flack, it this the part you use and hence why you're suggesting an oil filter chain?

[Andy]

I used one of the BES flanges to fix an immersion element in place in my HLT. I used one of those rubber strap wrenches to hold it in place and an immersion spanner to rotate the element. Locked it down well.


Andy.

Cheers Andy!

[Garth]

My immersons arrived today also, seem quite good quality, although I think I've paid way more than you John, as you can see mine also came with the round backnut.

I also got a holesaw from Screwfix, got the 64mm one so the hole will need a 1mm tickle all the way round, the next size up was 70mm which I though would leave the element a bit loose




Johnmac, does yours look like this inside?



do I simply exclude the thermostat from the circuit when wiring up? and what size cable were you thinking of using?

[Andy]

The thermostat should come out if you unwire it. The rewiring then *should* be obvious

[Garth]

Vossy, it's made in Italy, it's fairly thick walled, the bottom is suitable for a gas burner.

The thing at the bottom is a screw in blanking plate with a black rubber washer round it, when unscrewed it will accept a standard 15mm ball valve, although I'll probably go with one of those from BES like yourself, and drill another hole lower down as the height of the original will leave quite a bit deadspace.

Andy, the thermostat simply pulls out, withdrawing from inside the third 'prong', it isn't actually connected to anything at the moment.

[johnmac]

Garth, my elements are obviously from the same production line as yours.

do I simply exclude the thermostat from the circuit when wiring up? and what size cable were you thinking of using?

You can pull the thermostat out and discard it, or leave it in place and use it as a terminal block. ie, put the red wire in your picture and the mains live into the same terminal.

I think 2.5sq mm cable is recommended. Screwfix sell heat resistant cable by the meter, but I don't know if it's really necessary to use heat resistant cable?

I intend to go around the wiring shroud with heat resistant silicone, leaving a drainage hole at the lowest point.

I guess we need to be careful that everything's properly earthed.
