Water heating idea at RMH

I would come to a few ideas of implementing water heating to RMS, and would like discuss its practicality
before giving it a trial.

First option is placing a small steel flat radiator used for heating rooms, as a absorber of heat from the barrel. Probably between the wall and the barrel, keeping a gap of air 5 to 7 cm in between.

What would you think about it according heat that barrel can produce, would it be safe or too high temperature there?

Other one is to place it above the exhausting pipe in accumulation area.

Has anyone seen this before? Or any spiral in accumulation area?

Thanks for brainstorming.

Hi, Michael, Welcome to the forum.

I can't answer your question though I thought these threads might be of interest to folks wanting to heat water with an RMH:
