I hate this boiler I have 2 MPO147-tn. They are horrible. the most unreliable systems ever. My house is 48 degrees now. I have called a tech and am ready to take a hammer to this thing. I have had it apart and cleaned it and am ready to go get a nozzle myself. How much to replace this hunk of scrap?

I have an MPO147-DV. Are any of these issues related to Direct Vent installations? My brand new oil tank is in the basement, so the oil should not be too cold. It might be the setup, but every technician (and there have been many) has told me, “The last guy did not know what he was doing. I will set it right.” Two to three months later, then next technician tells me the same thing. The thing burns so dirty, that it just stops running and there is oil-soot all over the outside of my house.
— After six years of service calls and headaches, I am replacing this piece of junk with a brand new GAS furnace.

All these reviews with ppl P’ing and Moaning about the boiler… The great majority of fuel tanks these days are above ground and often in unheated spaces. I am willing to bet that ALL these ignition problems that were described are due to COLD OIL being fed to the burner. There are ways around this that your service techs should be aware of. Don’t bash the equipment until you are sure it IS the equipment and not the Knucklehead Bozos that call themselves technicians.

The problem is your set up that is being provided by the technician…. Secondary air, Spray angle (45′ SS Hago), and Z setting are critical on this small boiler…. I have set up several and they run great… Tech may also need to move Cad Cell To Ensure Proper Flame Sensing Intensity…. They are a great boiler…

I have this boiler installed in my home for the last three years. I’m a heating contractor and I felt guilty not doing anything to maintain this Rolls Royce of a boiler so just today I went and opened the combustion chamber. It was cleaner then my desk,
I did not have the exact nozzle size so I just hit it with a bit of brake clean, I’ll get the right size nozzle tomorrow.
I used my Bacharach combustion analyser to confirm the 87% eff.
I guess I’m doing something wrong because this boiler will put me out of business.

MPO IGNITION PROBLEMS: Try a Semi-Solid (SS) nozzle. The spray pattern will help ignition reliability. You may also try a 60- or 70-degree spray angle in this regard rather than a 45-degree angle. Make sure your oil pump pressure is at least 140 psi. Also make sure that there is not too much air (lean combustion). Your problem is more likely due to your service provider not knowing these “tricks of the trade” rather than the equipment– there are a lot of variables. The boiler can be tough to fire because it has a high back pressure– it’s what makes it efficient– and the burner has to “push” the products of combustion through the boiler– so make sure the boiler and chimney are clean and not causing an increased pressure for the burner to work against. If the nozzle is clogging prematurely, there is a fuel cleanliness issue; have an old tank? Try a product called HOT OIL (a fuel system treatment) and make sure you have a good fuel oil filter. If the filter looks like a tar baby when you replace it annually or less, that’s telling you something about the fuel in your tank. Increasing the filter size/capacity will also help if you have this problem, by giving you a little more time between maintenance cycles. I hope this helps–

In reply to D Walton. your boiler is either not sized right or its not piped correctly sounds like a installation problem

I have installed many of the mega steam boilers and so far have not had any of these type of problems. I beleive they are the best american manufactured boiler on ths market and give the buderus a heck of run for their money

I replaced a Burnham V8 with this new junk Mega Steam with the Beckett furnace on Dec. 18th, 20009, to date it is a problem. if it isn’t one thing it’s everything. i went through the winter cold. the house is not big but with the orginial burner and even the V8 the house was warm and comfortable on 68-72 degrees. i haven’t dared to turn the heat down below 70 because the house is COLD. i have to turn the heat up to 76-78 degrees just to get warm, then there is a blast of heat the house gets warm and then it goes back down to COLD before it heats up. i have had the service department so many times they should move in. today they changed the thermostat no change and this is after they had to change a part that regulated the pressure which was a “factory” defect. it appears that these burners are not what they claim to be no matter what. it’s all the name and the money behind it. as the “little” guy who paid through the nose for crap and i mean that what recourse do i have. it takes 5-6 minutes for the hot water to make it throught the pipes which is raising my water bill and i am using more oil than this new efficent burner was suppose to use. it is a lemon, plain and simple. where do i go from here?
