Looking For A Wall Hung Boiler

Bikerdadh Member Posts: 10
I work in a very old and congested area of New Jersey.
About 12-18 years ago a huge number of Hydrotherm- Celtic boilers were installed in my area. They are now needing to be replaced. I have been trying to find a replacement for them. There were two styles a direct vent model and (the tough one) a natural draft model. This is the killer. A lot of these home are row houses with no accesable exterior walls. The chimney is in the middle of the house and has more than one appliance vented into it. What I need is a natural draft wall hung boiler. Found a lot of direct vent but no natural draft.
I appreciat any suggestions.

    Take a look at the Bosch Aquastars Certain models appear to be draft vent.
    Good Luck

    No nat draft wall hungs

    You might get a small copper fin boiler like the Laars mini-therm, Alied Egineering has a steel fin tube. These are under 200 lbs and could be put on a stand.

    Thanks So Far...

    The Aquastar might be my answer. Looks like I will have to retrofit all the controlls and circuator etc... But it might be the answer.

    I have used the Mini therm many times, I do like the lars boiler, Believe it or not it doesnt fit in a lot of the locations I'm dealing with.

    Most of these homes are old cold water flats that in the 80's were converted into high priced condos. Now its time to replace the boilers, but with new codes it's next to impossible to find a product to fit the needs.

    Believe me I have been very creative, I've used the Lars Mini-combo,, the Weil Mclain AHE, and CGT. I've I'm looking at the Baxi-luna they claim to have a straight induced draft model comming in the spring.

    As of right now I'm still at a loss for the natural draft wall hung.
    Thank You for the info, please keep it coming...
