Title: need to heat a warming room that will heat 2 drums of product
Post by: adamant on November 23, 2015, 05:48:48 AM
i need to heat 2 drums of product for a process. the product needs a temp of 110 deg. the heating room is 6'x6'x8' high. i am looking to heat this with my boiler.

i am looking for a small heat reasonably priced exchanger . smallest i see is 50k btu.. to large

i was thinking  small hanging unit

...are you saying the product needs to be kept at 110f   :o

I would just install an aditional loop of pipe, add a fancoil and a thermostat and be done.
...or if you are not concerned with ceiling height, is lay some pipe on the floor and pour another slab (floor) on top.  Just have to watch water temperatures going into slab

A bit more info on what you want to accomplish and what your restraints are, would help with ideas.
Drums... meaning 55 gal steel?  Maintain 110 F for how long? Where is the "heating room" with respect to the boiler (and is it the OWB?) ?  Are you going to work in this room at 110 ? or just want the contents of the drum(s) to be that temp?

One of the big considerations for heater size will be how fast the temp needs to increase in the barrels. If speed is not a consideration then the heater needs to be able to overcome outer wall losses from the room plus a bit more to bring the temp up to the 110 degree mark.

Grainger has drum heaters that just wrap around the drum and plug into an electric outlet.

No matter what you come up with, good insulation is your friend, esp. under a slab if that's what they'll sit on. In a room that small, an old cast iron radiator would be easy and free or cheap if you can find one.

right now i have a 5x5x6 foot box i made that's insulated . i heat it with a electric oil filled radiator with a small fan. i can get that box to 120 deg with a lot more to go. i bypassed the inter thermostat and ran my own. due to the danger of doing it this way i wanted to utilize a loop from the owb.

The guys that do spray foam insulation have drum warmer on their 55 gal barrels of product to keep it up to temp when working up here in the frozen North. May be more controllable and economical solution.
