Wall Mount Boiler from NY Thermal? any good

Mark_34

I put a post up last week about looking for a new boiler to replace my 40 yr. system. I had some questions about the WM Ultra cast Aluminum heat exchanger and the problem with the Viessmann vitodens Max water temp of 167 deg F. I came across a wall mounted boiler called the Trinity from NY Thermal. It has a stainless steel condenser and a maximum supply water temp of 200 deg F and 92% AFUE. I talked to one of there sales people and he said they copied a lot of the design of the Munchkin but changed a few of the small problems that the Munchkin had. It cost about $2000 and it will do DHW with an add-on kit. The only problem is I have never heard of them. Does anyone know anything them?
there www page is www.nythermal.com.

I have looked into it and it sounds fine. I know that there are others on this site that have installed them.

I remember your original post. If you have large cast iron radiators in your home, the Viessmann may work great. You'll need to find a pro how knows how to install this type of system to calc the heat loss and the out put of existing radiation.

I have used several of these boilers. They have all worked fine. I consider them the best buy in condensing boilers.

Air Connections

The interesting thing about the Trinity is that it truly brings combustion air directly into the unit, I believe.

The other units bring the air into a cabinet (which is supposed to be airtight--some are, some aren't) and then into the unit. On these units, the air probably slows down a bit upon entering the airbox and can drop some outside air debris within the cabinet for the service tech to clean up during annual maintenance. Something like a filter. Just a theory.

Would the Trinity type of unit need an air filter on the exterior inlet?

Did the Glowcore have an air filter? I think they did at one point. Did that have a direct or airboxed combustion air? I forget. I probably worry too much. [g]

I am a homeowner who discovered the NTI Trinity while looking at competitor products and would have to agree with those who call it a "best buy." We have hot water radiator heating and use an indirect for dhw and we couldn't be happier with the Trinity's ability to handle both systems. The small size, quiet operation, outside air intake, outdoor thermostat, plastic venting, and most of all, modulating operation with variable btu's, are all big advantages that laypeople can appreciate.

200 deg F and 92% AFUE.?

If this is indented for a regular hot water heating system, then, those two figures are mutually exclusive - unless the water is moving SO SLOW, that, the system delta T is 100f,
IE: the water returning to the boiler at less than 100f (so that the return water can extract every drop of heat from the exiting flue gases) and discharging at 200f

Otherwise the AFUE wont be anywhere near that, and, may be a waste for your application – because in a typical hydronic system, the return water is only 20f less than the discharge water – and at 180 – you cant use the condensing temp advantage of the stainless steel HX, your are better off with the WM ULTRA – there, at least, you can utilize aluminum’s lighting fast heat transfer

Am I missing something?, Or are you using this to heat cold street water for domestic hot water use?

Having said that, I have never heard anything bad about NTI(nythermal.com) boilers

Trinty

Good boiler if piped Primary-Secondary and with proper pumps use 0010 or 0011

Have used them and they are ok but there are reasons they are the lowest price and yes the direct air in can cause problems if you have areas where dust is an issue they use the same heat exchanger as the munchkin but with smaller headers to conect the system you will require a higher head pump and some of the units have vibration issues ,still they seem to be doing Ok have had the first one in now for 2 years without any service issues , they have the same combustion fan as the munchkin though and have seen lots of posts for problems in this area had only 1 fan fail to date but have only used 6 units in projects to date , have had better success with the vissmenn and buderus over the years , the other issue is water content if you run them above the condensing mode in cold seasons make sure the exhaust doest collect against the house and damage the siding they put out a lot of moisture running at higher temp
