I'm replacing some old steel radiators on my Mikuni MX40 fired central heating. The rads seem to be clogged up with shite.
Anyway as it is not my main heating (2 coal fires as well) I was wondering if it might be worth putting cast iron radiators on it.
My thinking is that I can then run it for say an hour early morning to warm up the radiators and the radiators should stay warm for a bit afterwards if I use the heavy cast type.
Cast iron "old school" radiators are nicer to look at too.
Is it worth it? How long would they take to come up to temperature ?

This is a bit like the piece of string question, it will depend on your hotwater temperature, the water-capacity of your radiators and their thickness.
A thinner radiator with only some water capacity will warm up much quicker than a big one with heavy wall thickness.
But of course once hot, these big ones with lots of hotwater in them will stay warm for a lot longer, and they'll surely look much nicer too.
Up to about 10 years ago, you could buy them dirt cheap at "Brocante" places, but these days have gone, I've often seen English Vans loading them to bring them to the UK and make a (small) fortune selling them there.

Yes I noticed that some of the very beautiful french Art Nouveau ones seem to ask hundreds of pounds each on eBay.
Its possible to find much more basic cast iron ones pretty cheap just not ornate - they look like school or hospital items !
Another thing I was tempted by was the Bisque coil spring radiator but I don't think it would work horizontal and not much heat output either.

You're too late to find these for cheap prices nowadays, in the early 80's you would find them piled up at the scrap yards as people were very much into mondernising and nobody was interested in these old and very heavy cast iron beauties anymore.
Now they are THE thing to have, and some people are prepared to pay mad prices for them.
It's gone the same with old cars like the 2CV's, they were worth nothing, and today you'll have to pay around 10.000€ for a real good one.

I use radiators in the way you describe, but I too hated the ugly modern ones so I chose flat panel fronts and had vinyl pictures sized to fit.. these photos below are a bit grainy but you can get the idea. Much much cheaper than 'designer' radiators. SNIP I am awed every time I see the evidence of your artistic "eye" .................... Gobsmacking !!! |

Yes - very nice  What I'd really like would be to find normal panel radiators but round rather than rectangular. That would "go" really well |

Or is there something else which could be converted into a radiator somehow? alloy car wheels with a vehicle radiator core I suppose might work - with a fan behind so it worked like a matrix heater.

If you'll let your imagination work, you can find plenty of solutions, there's no reason the vehicle radiator wouldn't work, with the ventilator behind it it will take up more space, but apart from that it could be good.

You could try putting the front of a 2CV in front of one of the stoves and hiding a ecofan behind it.

Wow that is such a good idea, well executed! I particularly like the mini-library!

That's the one I like most too, it's the classic look, that will become a rarity in a few more years, as people are going more and more for books on "Kindle".

Getting back to the OP....
Doesn't physics say that it won't make any difference? XkW heat generated = XkW of heating. Whether it's cast iron rads that heat up slowly or tin rads that heat up fast, you've still generated the same amount of heat within the boat, surely?

Books are still outselling ebooks its down to price and people like a book. I have big rads on board the column type and they do store heat longer than the panel ones but take longer to heat up.
