Waste Oil fired radiant (hr)

Earthfire

another good looking compact work of art. any special tricks with the oil supply, filters, strainers ???

Fired up

this system yesterday. A 10,000 sq ft diesel repair shop. I used a 115 gallon buffer tank to even out the small office zone against the 8700 feet of shop zone.

Wirsbo 5/8' MultiCor 15" oc, and 1/2" 12" oc in the office zone.

The Clean Burn boiler purrs! I made the mistake of creating a hard to purge area in the top of the buffer tank. Took me an hour to purge up through the boiler. I need to rotate the tank to allow a high point air purge point.

Other than that the first call allowed the boiler to run for 45 minutes with a 50F slab temperature on start.

Fun to watch the temperature gauges on an injection mix point. Not uncommon to see 70 degree delta t's.

Tell them..

to follow the manufacturers manitenance instruction explicitly, or they too will be dissatisfied with the product.

The appliance name implies maintenance and operation instructions. Clean, burn...Clean, burn...

Beautiful job HR. Keep up the good work and tell everyone on Knowitall Ln Happy THanksgiving!

FYI

Take care when cleaning a waste oil heater - the remnants contain heavy metals. NIOSH resp + tyvec suits are in order.

CB makes the best waste oil unit (IMHO) & as long as the owners remember to check the air/oil adjustments, they'll provide excellent results.

Hot Rod, I noticed the B&G PL series pump you used on that job. Did you notice that pump to be noisy at all? I ask because I just started up a job with one of these last week and it's really noisy. I plan to speal to the B&G rep about it...maybe I just got a bad pump. This is the first one of that series we have used....I use the NRF22's and I love them.

The PL's

Are noisey. They are open design for cooling reasons and they just will make noise being constructed that way. I never use them in residential apps unless the boiler room is very isolated from the living quarters. They do however, move a lot of water for the buck.

hr

PL's are

getting better, noise wise. The very first ones were very noisy. This circ came with the Clean Burn as the boiler pump.

In this diesel shop the noise wasn't an issue. A large compressor will be located next to this boiler, that should over noise the PL

They are a fairly inexpensive pump if you need to move some larger gpm and head. Quite a bit cheaper than a comp wet rotor circ.

I suppose that open frame motor is less costly to produce. The line has been expanded and there are quite of few PL choices, now. A nice snowmelt circ.

Heavy little buggers! Don't mount them on a sheetrock wall in a residential application, the whole house will shake rattle and roll

Thanks

for the comments guys....I suppose we will have to replace this one with a quieter circulator.

Nice Job HotRod

That CleanBurn unit makes the Reznor Used Oil furnasty I get to work on sometimes look like a walk in the park.

Just out of curiosty, what is that brass device just to the right of the PL pump? I don't recognize it.

hr

That brass

is a Jomar Filter Ball valve. Inside the ball is a filter that can be removed wity the valve in the closed position. Gives you a strainer and iso valve in one package. I use these on start up to protect the pumps. I usually remove the strainer and hang it nearby after some run time.


It a fairly small tight mesh strainer and could cause cavitation down the road, with very little debris!
