PHOENIX OIL HEATER

EFFICIENCY = STACK TEMP• PHOENIX OIL HEATER is a division of ARIZONA BOILER COMPANY, INC. doing business since 1960.• Our PHOENIX OIL HEATER is the most efficient oil heater on the market today, which is why we mount a gage in the exhaust stack as well as at the hot oil outlet. We

guarantee the stack temperature on our Phoenix, PX models, to not exceed the outgoing oil temperature by more than 100°F while on “high” fire. Low to mid-firing usually has a stack temp under 50°F over oil outlet temperature.

• Heaters of 10 mil Btu/hr and less are made with double helical coils and do not need economizers at operating temperatures below 500°F. Larger heaters are single helical coil units with economizers.

• As you shop oil heaters, be sure to ask the manufacturer for their “stack temperature guarantee.”• Efficiency is claimed by some manufacturers in excess of 80%, with some as high as 90%. Talk is cheap. We put our money where our mouth is. • We guarantee “Real Efficiency” demonstrated by LOW stack temperatures! • ASME CODE CONSTRUCTED • All Phoenix Oil Heater, PX model heaters, are designed and built according to Section I of the ASME code. Our minimum design gives the PX Heaters a minimum

rupture pressure of 350 psi.• ASME stamping and National Board registration, are both optional on all PX model heaters.• Some manufacturers do not make ASME code heaters. If you don't need ASME stamping, we can save you money while still building a heater designed according to the

ASME code.• Other oil heaters on the market are not pressure rated nor ASME stamped. • Some of the more popular oil heaters are not designed according to ASME at all. In fact they are not even designed for ANY pressure. An accidental pressure of 20-30 psi

could cause one of these heaters to completely fail and dump hot oil all over the area.• Protect your investment: ORDER ASME CODE HEATERS• ENERGY SAVING • Like gas mileage in cars, efficient can vary greatly in oil heaters. But unlike cars, which are tested by the EPA, no independent government organization is testing oil

heaters to determine their efficiency. Claims are easy to make. Proving OUR claims are easy, with stack temperatures and excess air measurements.• As you consider purchasing a new thermal oil heater, be sure and ask the manufacturer for their “Stack Temperature Guarantee.”• We installed a new Phoenix “High Efficiency” Hot Oil Heater here in our yard for testing. It was connected to two heat exchangers circulating water with a 7000 gallon

water tank to carry off the heat from the heater. We installed one of the high efficiency Limpsfield burners with Autoflame controls. We had a big economizer on the heater and found that the heater was so efficient that we didn't need the economizer. There was not enough heat in the exhaust to try to recapture it.

• At low to mid range, 25% to 50% firing rate, the stack temperature was 390°- 405°F, well below the outgoing oil temperature of 476°F. Actually only slightly above the “Return” oil temperature of 395°F. At 75-100% firing rate, it was still below outgoing oil temperature, only 50°F above return oil temperature.

• Other manufacturers are claiming 85-90% efficiency for their oil heaters. In our humble opinion, that is physically impossible in anything other than a water heater operating below 140°F. They juggle the numbers and somehow come up with that fantasy. Efficiency is very simple. If a heater inputs 100 Btu of gas; 80 Btu goes into the oil and 20 Btu is lost up the stack (or lost thru radiant losses): That is 80% efficiency.

• • TRUE EFFICIENCY is measured by stack temp and excess air. • REAL EFFICIENCY, you can measure at the gas meter every month.• We have a brochure from a competitor in which they correctly state that efficiency all boils down to stack temperature in relation to outgoing oil temperature. They are

proud of their stack temperature being 150°F over the oil temperature; on “low fire”. And this is with the oil temperature being only 375°F. At high fire, their heaters are typically 200-300°F over oil temperature. (According to their brochure) By my calculations, that relates to 65-70% efficiency. They claim 84% on low fire and 78% on high fire. Talk is cheap. Be sure and ask for a “Stack temp” guarantee.

• The below pictures demonstrate our stack temperature in relation to the oil temperature. When firing at 76% firing rate with an outlet oil temperature of 476°F, return oil temp of 412°F, the stack temperature was 410°F.

• We can guarantee the stack temperature to not be higher than 100°F over out going oil temperature when on “high fire”. At low to mid fire, the stack temperature will be below outgoing oil temperature.

• We claim to have the most efficient oil heater on the market in North America. Give us the chance to prove it to you.

Efficiency = Stack Temp• HOME Page:• PHOENIX OIL HEATER is a division of ARIZONA BOILER COMPANY, INC. doing business since 1960.• In the 1990’s as fuel cost sky rocketed, we saw the need for a more efficient oil heater.

• There are old formulas, built into computer models, that take the excess air and the exhaust temperature Delta T (stack temperature minus the ambient temperature) into the “efficiency” equation. These formulas have been around for many years. They are the standards which guide us as we design and build our oil heaters. They are built into most Combustion Analyzers.

• We can send out a video showing our stack temperature in relation to the oil temperature. When firing at 76% firing rate with an outlet oil temperature of 476°F, return oil temp of 400°F, the stack temperature was 410°F.

• Even better than that, we can guarantee the stack temperature to not be higher than 100°F over out going oil temperature when on “high fire”. At low to mid fire, the stack temperature will be below outgoing oil temperature.

• In addition to “heater” efficiency, we offer the option of installing Limpsfield burners with Autoflame micro-modulation controls. These burners are quite simply the most efficient burners on the market, measured by the small amount of excess air required to achieve a complete mix of fuel and air, resulting in complete combustion in a shorter space inside the heater. This allows more time inside the heater to be transferring heat from the hot gases into the oil. Because of the quick-complete mix, the Limpsfield burner needs less excess air (or oxygen) to achieve a complete and clean burner. They guarantee a clean burn at 3% excess O/2, or 15% excess air. Typically we are able to achieve a clean burn (low CO) down to 2% O/2 – 10% excess air. Remember: Excess air just carries off valuable heat.
