in Gas Heating
I, hopefully, will be converting from oil to gas in the near future. About 10 years ago I added on to the house and converted my heat to radiant. I had Northeast Radiant Tech. set up my system. Part of that was providing them with all room measurements, window sizing and r values, floor materials, wall insulation, etc. How does that relate to a heat loss calculation?
Rest assured, this will be the first of many questions as I get closer to the actual conversion.

Those
numbers do not relate to a heat loss calc , they ARE a heat loss calc. I don't understand the question maybeYou didn't get what you didn't pay for and it will never be what you thought it would .

Just to clarify
A fair point. They provided me specs of outside temp=0 degrees, room temp=70 degrees and a total heatload w/o dhw: 38K btus/hr. I guess the question should have been, is this a heat loss calculation? If not, how does it relate to the calculation. Thanks.0 -
Yes
Your house gives up 38k btu/hr of energy to the great outdoors on your coldest design day. This is the amount of energy you must put back into the house to keep it cozy on that cold day. You will want to look at the output ratings on the boilers rather than the input.If you are at altitude, you will need to do a bit more math.
If you provide more details about your present setup folks here can be more helpful. How is your radiant set up? How do you heat your DHW?

a bit more info...
The house is an 1800 square foot cape on the north shore of Long Island. Built in the early 50's and extended/dormered about 10 years ago. Windows and insulation updated at that time with the exception of 2 rooms on the first floor. Full, unfinished basement.
Heat is currently provided by an oil fired boiler. Three zone radiant heat controlled by a Tekmar 370 controller with outdoor reset. DHW comes from a recently installed 60 gallon indirect tank, also controlled by the Tekmar unit.
I hope this helps. Thanks0 -
