    hi this is my first time on this forum.

    I had a weil mclain eg55 millivolt that provided all the heat in all my rooms 72 degrees during the day 68 at night. All the risers were replaced 2 years ago and the system had the millivolt replaced and it still worked well.

    Last winter we had an issue and was told that the millivolt was no longer available and we would need a new boiler. The weil mclain boiler was installed in 2004. Our local plumber does not like Weil Mclain so he wanted a Burnham. He installed a Burnham in6 and now we are getting uneven heat. He did not do a heat load calculation of any kind and has said that what I had was a Weil Mclain eg45 which is not true according to my records.

    The night heat is still set at 68 degrees and gets heat until it reaches72 degress for the daytime and never goes on again.The house we measured as best we could is about 3,000 sq.ft taking in 10% for no insulation and climate zone 4.

    I have had 2 plumber who feel the boiler is too small. They suggest changing the 2 main vents but cant say that it will work. I payed $ FOR THE NEW BOILER and would need to pay an additional $ more for the 2 vents.

    So my question is does a burnham in6 give the same heat as a weil mclain eg55 as my plumber is insisting thatI change my thermostat and add heat senors. I'm 82 and this will probably be my last boiler so I rather just put in what I had a new weil mclain eg55 and be done with it. Any suggestions would be greatly appreciated. Thanks.

    @caren , you also need to remove the pricing info. We do not discuss pricing on this site. See:

    We need way more information.

    For starters most millivolt parts are still available, possibly in a different form than the original and worst case you could put in a 24vac valve and a transformer.

    Is this a steam system? I assume it is from the post you added this on to but we have to ask.

    (kind of getting ahead of myself assuming it is steam)

    Are the convectors 1 pipe or 2 pipe. Can you show us a picture of a convector with the cover removed?

    Given the chain of events here it is far more likely that the boiler isn't piped right than it is undersized. Steam boilers are sized to the connected radiation, not the heat loss of the building although especially on 2 pipe systems you can undersize the boiler some compared to the connected radiation. A boiler smaller than the radiation can work on 1 pipe as well but you need to carefully balance it and everything else has to be right.

    Can you also show us a couple pictures of the boiler from far enough back to cover the boiler and near boiler piping?

    @caren

    And post your city/town. Maybe we know someone who can help.

    To answer your question the IN6 is smaller that an EG-55

    We need to see some pictures of the boiler from 10' away showing the piping so we can see if it was installed correctly
