In the drawing 2 represents a heating unit in
45 the form of a, boiler for a hot water or Steam
heating system. To illustrate the invention the
boiler S is shown as being of the circular type
but it will be obvious that the heater of the invention is adapted for’ use in connection with
50 various types and sizes of boilers. The invention
is not concerned with any particular type or
?ring means; that is, the boiler may employ coal
of discs 01‘ rings encircling the body “I and are
preferably vdisposed so that the plane of their
55
surfaces are transverse to the run of the body.
The ?ns are relatively thin and being disposed 40
as they are they function to facilitate the trans
fer Of heat to the water within the heater. The
?ns are preferably unconnected so that any tend
ency thereof to‘ deflect 01‘ Warp When heated is
obviated and this is desired to avoid cracking of 45
the heater
The heater I4 is Placed Within the boiler at a
point above the ?re Which in the Case‘ of an oil
burner is above the ?ring head so as to be in the
path Of upwardly traveling heat.
The heater is 50
or similar fuel, oil or gas or the like as the heating
connected to the Water chamber or chambers of
the boiler at its or their upper and lower sides so
the heater is in parallel relation in respect
