Certainly contact Robert Bean as stated above . You will find no one more qualified for this type task . PERIOD . A properly designed radiant heating / cooling system will not present any condensation issues . https://www.supplyht.com/articles/97959-get-beyond-your-fear-of-condensation-in-radiant-cooling-applications

No radiant works without insulation on the opposite side of area to be heated . Heat does not rise , hot air does . If the resistan ce below the radiant tubing , plates , etc is less than the resistance above very little heat will travel to the space meant to be heated . It's all about resistance , heat energy , like water or air is lazy and stupid and will travel the path of least resistance . Insulation is REQUIRED

Jon R , Let me know how that works out . Downward losses are not really what you want . You probably know better than I though .

Re: Boiler ratingsDo you have to use oil ?

Re: Boiler ratingsI rarely recommend mini splits . Was just wondering if any type gas was available . What type heat emitters do you have in the home ( baseboard , panel rads , , etc )? How well constructed is the thermal envelope ?

Maintaining a jacket temp to insure good DHW performance year round is a fool's errand . Lots of folks say having one appliance is best , in this case whether fuel be NG , LP , oil , they'd be wrong . Use a stand alone , well insulated tank type water heater if using cast iron boiler .

Probably like NJ and other states Dana. They adopt a code but some localities do not enforce it . Don't quite know how that happens but the phenomena certainly exists To the OP , you cannot go wrong with EnergyDocs , Mike does really good work

You need not replace the unit . You need someone to perform a room by room heat loss calculation , perform an installed radiation survey , correct any terrible near boiler piping ( it's there ) and properly size a buffer tank . 2 pipe buffers are better since the tank is not flow through , the load should be between boiler and tank so the tank sees less flow and remains stratified longer sending colder water back to the boiler for a longer period annually . Who sold you the equipment or where was it purchased in Westchester County ? Difficult to find someone qualified in Westchester . You may need to each out to someone in another county .

Roger Berry . Most of the outbreaks you hear about are because they happen in large gathering places . fact is that 50% of cases are misdiagnosed as a form of pneumonia and they are isolated due to originating in households .
