Steamhead

for a steam or hot-water system?

comparsions

anybody have any comparsions

Charlie from wmass

Lots of comparisons

Scotch marine is lighter as a unit but one piece block  to install. Tubes can be changed in a scotch marine. Water volume is lower in scotch marine. Efficiency should be higher as scotch marine is multi-pass. Water quality is important for both but more for scotch marine as it is steel.

thanks

thanks for the reply, is there any proublems using a drop header on a scotch marine boiler. (it would save digging a pit). I know they work well with cast iron and i cannot see the differance??

Charlie from wmass

I can not answer that.

Even with a Scottish father I have limited experience installing scotch marines. The ones Da worked on were Industrial level, Paper mills, Schools,  and such.  So Dropp headers were not needed as they had plenty of head room.
