Ok, first off Happy Thanksgiving!
I'm curious as to whay type of sidearms anyone is useing for DHW. This setup is not for me, but I have a few jobs that have old Bock oil water heaters that are failing (a lot of those up here some 20+ YO) My expierence leads me to believe that electric water heating is the way to go in the summer, and oil/wood in the winter......so an indirect. I've touted the "best of both worlds for awhile" as an electric with a bronze circulator going through a tankless coil. This poor man's indirect is heated by oil in winter and electric in the summer. Now, I'm looking at a job with a Buderus and no tankless coil, so I am going to use a sidearm, but there are two types out there. One is basically a pipe in a pipe 48" tall, and the other is multiple smaller pipes in a single pipe, shorter but claiming more surface area. I'm concerned about long term scale, and establishing a good thermosyphon. Thinking the tall simple one would work better, but looking for some real-world expierence, preferrably long term setups and their charictoristics. Thanks in advance![shock !!! !!!](/talk/styles/default/xenforo/smileys/shock.gif)
