In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
My System, or what is left of it.
Installed in the house around the mid 40's. Radiant heat embedded in plaster on the ceiling. Return line 1 ¼ as well as feed. 3/8 copper snaked on ceiling at approx 10 inch centers. The house is 1600 sqf. All one level. Every room has the heat system in it so all 1600sqf is heated by it. It is one zone. One thermostat. You can shut off rooms by closing manually the valves placed throughout the house. I will include pics.
When I purchased the house, there was a rather large old oil boiler consuming about 1 ocean going tanker of oil every month. One winter later I replaced it with a Budures wood/coal fired boiler with a Superhot 30kw electric as backup. The wood boiler was rated at 96,000btu and the electric just over 100,000. The wood boiler worked very well when the outside temp was below freezing. I could keep the water temp at 140 without a problem. But she ate a ton of wood. The electric would work well as it had 6, 5000w elements that modulated to demand. All in all the system worked great. As time passed, I got sick of cutting firewood. As more time as passed, I am sick of paying hydro. I do now believe that these two units were over sized.
Everything is ripped out. Only 2 pipes sticking out of the ceiling. Return and feed.
I live in Squamish BC Canada. Half way between Vancouver BC and Whistler BC. We have 4 defined seasons here with winter lows that have hit lows around 0 in the past, but with weather as it has been going, the lows we hit are around 15. But not sustained for a long period of time. May be a week and a bit at most. And not very often.
I have been attempting a few heat loss calc's and have come up with some numbers. Slant-fin has an app that I tried. Came up with 44,000. I used temps 72 for indoors and 30 for out. Measured every room, window, door, outside walls and everything else that wasn't moving.
Using a simplified method at 40btu per sqf for a uninsulated house or very poor, that number is 40 times 1600 = 64,000.
Well, my old shack is fairly well insulated with double glazed windows (albeit older ones) so I figure to use 30btu times 1600 which gives me 48,000.
If I am off tract, please let me know.
Have been researching boilers for at least 2 months now and became more confused with the more I read. Until I found this site. Right now, I have my heart set on a Triangle Tube. Was looking at a Navian as they are popular here but not impressed after some research.
Thinking of just going with the straight boiler. No DHW for now. Want to keep it simple and warm. The Prestige Solo 60 NG is looking like a fit.
Please keep in mind that I am NOT a heating guy. I just would like to do research before attempting to do it or hiring someone.
Thanks in advance for your input.
