Onoff Posted April 21, 2017 Share Posted April 21, 2017 (edited) Having run out of oil recently I got back to thinking than an immersion would be handy to have as a back up for hot water. The existing copper cylinder that came with the house (nom 1070x450) is "wedged" up under the rafters. There is an unconnected immersion but it's all broken about the terminals. I reckon it's about 17 or 18 years old. It's also the "wrong" side to access / replace. The immersion site right under a rafter. So I thought I'd go grab a new st/st one. (I don't want to move the hot water cylinder or bugger about at the mo thinking about a TS or UVC btw). But I'm confused. There's this one: https://www.bes.co.uk/indirect-stainless-steel-cylinders-1065-x-450-mm-48in-x-18in-160-litres?ref=gs&gclid=CI6d-uH6tdMCFbgK0wod7GYJkA Or this: http://www.screwfix.com/p/rm-indirect-ss-cylinder-1065-x-450/93313#product_additional_details_container They would both put the immersion the right side for access. What's the better make Stelstor or RM? And for the same overall size the Stelstor says it's 160L but the RM 206L? Both stainless. Very odd! Extra litreage would be good.

Nickfromwales Posted April 21, 2017 Share Posted April 21, 2017 Don't buy either, stop running out of oil, and save all the expense for when you change to the TS / UVC+buffer. . It ain't broke so don't fix it ? Link to comment Share on other sites More sharing options...

jack Posted April 21, 2017 Share Posted April 21, 2017 Might also be a job for a Willis heater. Bit of pipework involved, but a lot cheaper and easier than replacing the cylinder. 2 Link to comment Share on other sites More sharing options...

Someone with some sort of clue will be able to tell you how low on the tank you should consider fitting it. The Willis-type arrangement would likely be less of a faff.

Jeremy Harris Posted April 21, 2017 Share Posted April 21, 2017 (edited) Yes they are short 15mm fittings, but the things work like a dream, far, far better than an immersion in the cylinder, We stayed in a cottage up in the Antrim Glens a few years ago, lovely place, miles from any other house, All the hot water came from a cylinder with a Willis heater sat in the bottom of the hot press. The really great thing about the Willis is that you get enough hot water to do the washing up after maybe five to ten minutes, as it always heats the very top of the tank first. I'd strongly recommend one, based on our couple of weeks of using one. As a side note, I just really love North Antrim, one of my favourite place in the UK.

PeterW Posted April 21, 2017 Share Posted April 21, 2017 Willis Heater is ideal for this situation - it's a couple of hours to retrofit but use compression fittings not push fit as it can get pretty hot on the top tee. Also makes it easier to remove it when you get round to fitting that UVC..... Link to comment Share on other sites More sharing options...
