based upon my research and Heatpro's answers to my questions I am doing the following: throwing out my old oil boiler and installing a new high efficiency (92%) gas burner (Trinity i100 set to come out in the next few weeks). I will throw out my old cast iron radiators and put in convector cabinets type F at http://www.ocsind.com/cab_types.html with steel elements http://www.ocsind.com/convector_elem_steel.html, in order to avoid running baseboard (my sister-in-law stands on those convector covers to open and shut her windows). These are very easy to install, are very durable, work for hot water and for steam. You can get these things for alot less than the list prices publicized.

I locked in for 5 years at 1.39 cents per therm for gas. (1 gal oil is equivalent to 1.4 therm) At that price it is equivalent to locking in at $1.93 per gal of oil for 5 years, which is great, considering oil is about $2.50 per gallon and will probably increase in price during the next 5 cold winters.

The name of the company to lock in is called Infinity Energy at 1-800-724-1880 x1 x1 x3 x1.
and I believe that they supply to New Jersey as a result of deregulation. Last month, Con Edison charged me more than $1.65 per therm. I can predict almost exactly how much I will spend in the next 5 years.

For example, assume someone uses 2000 gal oil annually for heat and hot water. At 70% efficiency 1400 gal oil actually used to provide heat and hw and the other 600 gal oil goes up the chimney.

in therms, you need the equivalent of 1.4 * 1400 = 1960 therms. If your boiler is now 92% efficient, you would need 2130 therms with the new boiler to provide the equivalent of the oil boiler using 2000 gallons of oil.

If oil prices do not go up for the next five years, the cost to heat the house is $2.50 * 2000 = $5000.00

If the boiler is changed, the cost to heat the house is 2130 therms * 1.39 = $2960.00

the savings per year should be at a minimum of about $2000.00 per year, assuming oil prices do not rise in the next 5 years.

That is a guaranteed savings of $10,000 in the next 5 years, and that is assuming oil prices will never rise over the next 5 years.

my piping will be according to http://www.heatpro.us/eurotree/

the postings below from heatpro to joe clarify more how to get the most out of the condensing boiler, and how to set it up
