Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

It is a not a waste oil burner. A Beckett that burns light oil, easiest burner to work on for a TECH.

Call local service company they will have it diagnosed in 10 Mins.

The carbon build up is in the preheat block not the firebox. Spraying water into a firebox is a terrible idea.

100%,!! yes for carbon buildup and silly for water injection

None of this is for a hobby or should be taken lightly. To see a big flame shoot out of a tube powered by WO or even WVO and say I can heat my... whatever, is reckless to say the least. The WO salamander heater I'm speechless.

It takes alot to get these to run properly. Please be careful. They will run away when you least expect it.
Waste oil holding/heating tanks,sketchy at best and should not be sold.

Don't cheap-out on Safety controls, limits, aquastats, heat exchangers.
The "burn what ever you want"  is wrong.  They do not self adjust to different oils.

Because making a flame in a drum dosen't mean you can put it in a heating appliance.
To do that is another set of rules.

A good 80% of these burners will burn down your house is second. The false information that goes along with them and the false sense of security is of great concern.

No new mouse traps have been made.  Be careful and pay attention.

What model Buderus are you running? 

OK what did I miss?

If the gas Spa boiler dosen't melt down a create a nice hot fire it will soot and plug up first. Then catch fire.Take effeiciency and throw it out the window.

Venting through PVC..No! At any temp.
These burners need Draft. Keep boiler warm=better burn and draft. Honeywell 6006 @180 10-20 degree diff.

Secondary air has little bearing on eliminating soot, making a clean flame. Something else going on. Tight chamber. Remember Chris Farley? Fat guy little coat.

None of these burners take a liquid to a gas. They atomize with pressure or air. I do have a vaporizer,  a different set of rules.

Flue up and out as quickly as possible is good. (Durvent All Fuel) Would rather keep flue WARM Not HOT for decent draft. Remember a cold colum of air is dense and dosen't like to move.

Outside air only if the building is very tight, then must be warmed.

Kaowool can be your friend in a cleaner burn with a boiler. Depending what boiler is chosen.

Get a clean burn, good draft and don't overthink it.

Nope, not checking your math. Sounds good to me.

Insurance claim in the making.
