Burner choice advice?

[Michael B]

I have a Pensotti boiler block R1-30, s/n 1515149 No.4 sections with a Mectron 5M type 217T burner system.

I need to replace the burner and am looking at the Rielo 40 series. Maybe the F5?

Is this a good combination?
Is there another I should consider?

Thank you,
Michael B.

Obviously you take care of the system yourself so simply go with that recommended by the installing contractor. Now that was easy, eh?

The system was already in when I bought the house 13 years ago.
At the time, the home inspector commented on the good job the installing contractor did on the system. The first two guys I got to take care of the system said the same. They both moved away.
Now the two outfits I had come in want to rip out everything and start over. I asked why and they both said; “Well, the system is old and just should be replaced.” I don’t trust them, and believe they are just looking for a big dollar job.

The Pensotti boiler is still sold brand new in the USA. So it's not that outdated. In fact, our company sells the Pensotti as the highest AFUE high mass boiler in our marketplace. It's AFUE rating is in excess of 88%, not too shabby if one needs/wants a high mass (cast iron) boiler. For low mass oil I own and recommend the System 2000, which has a lower AFUE rating but a much higher overall energy factor.

The Riello Mektron oil burner was superseded more than a decade ago with the Model F burner. If your boiler is rated between .75 and 1.75 gph input, then theh F-5 model is what you'd need. Please note that the input ratings are given in gallons per hour total while a nozzle is rated at 100 psig. Thus, the nozzle rating and the actual input to the boiler are two different numbers, dependent on the oil pump pressure. Whoever sets up your burner needs to have an oil damped pressure gauge to set the pump pressure accurately.

Thanks skippedover.

I have a friend who is HVAC licensed in Massachusetts. Great guy. He's south shore and I'm in New Hampshire.
