The MPO Boiler is one of the boilers that were designed with an innovative design. The main ideas for creating this boiler are the efficiency, the quality and how easy it is to service the boiler. The efficiency rating of the boiler is 87% AFUE and they are proud to say that there are no other boilers in the industry that is more efficient or even more reliable in providing of heat.
The MPO Boiler System has a one of a kind 3-Pass Cast Iron Design. This makes the boiler’s efficiency increase because there are more passways for the heat to travel through before coming to the heating system that heats your home. The 3-Pass Cast Iron Heat Exchanger takes as much of the Btu’s from the combustion process and uses them to heat your home.
Each MPO Boiler comes with a one of a kind return water device that will automatically mix the hot boiler water with cool return water. The instrument can also keep the temperatures steady, this will also help improve the efficiency of the boiler.
There are 5 different sizes to the MPO Series Boiler, the MPO84 has a heating capacity of 74,000 MBH, Model MPO115 has a heating capacity of 98,000 MBH, Model MPO147 has a heating capacity of 129,000 MBH, Model MPO189 has a heating capacity of 167,000 MBH and Model MPO231 has a heating capacity of 203,000 MBH.
Some of the features of the MPO Boiler System include, a Large Combustion Chamber. There are other systems that need a target wall to increase the heat but with this system there is no target wall or blanket, this will help increase the transfer of heat and will lessen the amount of repairs on the system. The MPO also has a Removable Flue way Baffles, this system will let the boiler to be installed in a multiple of different ways with the chimney application and will also allow cleaning to be done with ease.
The boiler is surrounded with a 3″ thick insulation, which is centered on the boiler block. This insulation will decrease the amount of heat loss that often escapes through the boiler jacket. The MPO has Honeywell Aquastat which is an electronic aquastat that includes a digital display and an interface that has the capacity of giving the homeowner diagnostic information. This style of boiler will help you save money on repairs, because as these diagnostic systems tell you when there are problems, you don’t have to wait until the problem gets worse before you can repair the system.
If you live in a home that does not have a chimney, the MPO-DV (Direct Vent) is available as an option kit. The kit includes a stainless steel sidewall with a concentric vent/air intake termination. There is insulated pipe that come sin lengths of 5, 10, 15 and 20-foot lengths. The Burnham MPO is one of the best boilers in the market; if you are thinking about replacing the old style boiler you have now, think about the MPO and make the smart choice.
HAve recently (10/31) had a Burnham MPO84 (with Beckett AFG burner) installed in my home. Being early in the season and since I do keep my home fairly cool (55-60F) it did not run much until late November. Since Thanksgiving i ahve had the installer/servicer in four times due to igniton failures varying from poor ignition (taking several tries to stabilize) to absolutely no ignition at all. Problem seems to be related to clogging of the low-flow nozzle (.5 gph). When the nozzle is changed, igniton is prompt. Great except I can not have the servicer coming twice a week to replace the nozzle! Yes we have checked the oil and twice replace the filter cartridge. Does this sound at all familiar? Am getting to the point that I have no confidence at all in this unit.
- I’m in the same boat with Tom. Our MPO84 worked like a champ heating water. Soon as winter hit – bam – no ignition. It only does it when the temps are in the single digits, to add insult to injury. I’d love to have clue why this is happening to a unit that seems to get such rave comments on the web.
- Thanks!!
Same type of problem with the MPO84. Worked fine for 3 months until the weather got really cold, then ignition problems started. Woke up freezing one morning and called my installer. Of course they tried to blame the oil line but that was not the problem. The Beckett burner uses intermittant ignition which was not working properly. As I was told, the tech wired the ignition differently so it is on all the time when the motor is running. So far, so good, but this is NOT how it was intended by the factory. I’d like a better “fix” explained to me if possible. I’m also not very happy with this unit so far.
I have the MPO147 wBeckett NX burner. It has been a headache every heating season. Heats water great in the summer, son as winter hits, the burner carbons up!! Company states it has to be set up with a combustion analyzer( 11.7-12.0 CO2, .085 B Hago nozzle, 180 PSI are the recommended specs) which doesn’t make a bit of difference. The aforementioned specs dont allow the unit to run better than 84.8% efficency. The company is misrepresenting the capabilities of the boiler. Bottom line, it is unrelliable and the company knows!
HOW DO I CHANGE DRAIN VALVE ON MY BURNHAM BOILER
Here in Alaska we run into cold weather issues often w/ oil. Check 1. Is the fuel oil supplied type 1 or type 2? 2. Do you have a Tiger Loop installed on the Burner? These help warm the oil before it hits the nozzle. 3. Do you have a water filter? 4. Have you tried wrapping a heat trace on the fuel supply line with poly insulation around it? Usually if a burner works adequatly in warm temps, it will with correct protection on the fuel supply. In extreme temps a Day tank can be used, ensuring room air temp fuel hits the burner, eliminating gelling of the oil.
