Who are standing on the heating parapet boilers, your feedback ....

  1. A cheap, budgetary solution, other than the price of the issue, no advantages.
    I operate such 7 boilers for years with the Honiwell automatic system and the circulation pump working overhead.
    With domestic automation and without pumps, a continuous headache.

Serious firms do not produce such boilers, but give the attachment to ordinary floor boilers. Many owners are tormented by changing Parapetnye ktly the next year.
  2. I put -XXXXXXXX, with a coaxial pipe. 310 year works fine, only in winter it has large suctions formed, you need to periodically knock down. And turn the exhaust down, so that water does not suck.

  4. Parapet gas boilers with steel heat exchanger. Non-volatile (with the removal of combustion products through the wall).
