MtB Posted October 17, 2017 Report Share Posted October 17, 2017 About a year ago someone posted a link to a firm selling cheap and cheerful calorifiers. Sub £200 for a simple one IIRC. Does anyone remember? Or better, still have the link? Many thanks... Link to comment Share on other sites More sharing options...

It didn't work directly, but led me to http://www.ebay.co.uk/itm/like/180916701070?clk_rvr_id=1338539717492&vectorid=229508&lgeo=1&item=180916701070&rmvSB=true Link to comment Share on other sites More sharing options...

Unless I'm missing something, it is seriously lacking in good information 1) Dimensions for each size 2) Bore of heating coils 3) Size of connections 4) Max tested pressure / recommended PRV pressure value. It is at least different from the relatively few types that otherwise actually seem to now be being sold. Many places are only offering the pre-plumbed models by Surejust/Surecal, (although some, like ASAP supplies seem to be branding these "Hotpot"). These are the shiny bright blue "wrappered" ones. What I found was that although several places sell a non pre-plumbed model, this time in a dull light blue, not "wrappered", it looks from the apparently identical pictures used that they may all be from the same source, even though prices being asked differ substantially. This example from Kuranda's web site.... Link to comment Share on other sites More sharing options...

From the photo they look to me like plain low-tech open vented cylinders. Not designed or tested for use as unvented. 1 hour ago, Mac of Cygnet said: In 2015 you yourself posted a link to cheapo calorifiers.

Not sure that is the link I was looking for but as my application is vented and very low pressure, one of those will do fine! Link to comment Share on other sites More sharing options...
David Mack Posted October 17, 2017 Report Share Posted October 17, 2017 I had a domestic copper cylinder made to measure by Newark Copper Cylinders. Very good service and no more expensive than an off-the-shelf size from my local plumbers merchant. Their standard marine calorifiers are at https://shop.newarkcoppercylinder.co.uk/marine-calorifiers . A big range of sizes, horizontal/vertical, single/twin coil etc. 1 Link to comment Share on other sites More sharing options...

It says they are "own brand" but also says they are made by Mannley Cylinders in West Yorkshire, so it looks like "Copper Cylinder" are not the actual maker. I will check this out to see which is cheapest, but interesting you can specify a lot of options, (albeit at a lot of cost in some cases). Mannly Cyliders also have a web-site, but each time I try to Navigate it, it completely freezes up Firefox....... Link to comment Share on other sites More sharing options...

Neil I am deep in calorifier research at the moment, (did I hear someone say "get a life!"). My quest is actually to find, (or have something made), that has a wider bore coil, as, (if possible), I would like to try and get water circulating without necessarily having to pump it all the time - it may not succeed, but it would be a great gain if it could be made to work, so worth the effort experimenting, I think. If anyone has a suggestion for a supplier for a calorifier that will heat on gravity alone then I would be very interested. However, back to the quoted posts...... Unless someone knows otherwise, I think coppercylinder on eBay is not the same outfit as the one in hilandnick's link (above). The former has a Manchester phone number, whereas the latter has a Leeds phone number. I currently have a query raised with the latter, and am awaiting a call back.

My old cauliflower had 22mm connections to the heating coil which appeared to have no reduction in diameter in the coil itself which I suspect might help your quest, unfortunately it wasn't labeled so no real help, sorry The new one had 15mm conections which I didn't notice when buying it, this went a long way towards my screaming abb dabs during the fitting process Link to comment Share on other sites More sharing options...

However I'm getting the impression that specifying 3/4" BSP instead of 1/2" BSP wll not actually mean the internal bore of the coil is bigger, (but maybe I'm wrong). They have just rung me to say they have failed to get an answer from the manufacturer today, so I'll have to wait longer to know how it all works!

"copper cylinder" have just confirmed they can also do one for me - an extra £60 over normal cost. (Maximum possible is 22mm, and would have 1" BSP connectors). I quite like the idea of Surejust/Surecal, though, because of all the pre-plumbing. I know you pay extra for that, but it absolves me from having to fit immersion heater and fittings into a very expensive tank, made of very thin copper. I'm scared stiff of spannering too hard, and ripping it apart! I will now investigate comparative costs of each option tomorrow. Link to comment Share on other sites More sharing options...
