constant flow in floor setup?

GW

so, when you say "boilers", i take it there are more than one? And both are coming on no matter what the temp is outside? Is this constant circ? If yes, how in the world does it not overheat in mild weather?

What's the proper way to control this?

A customer I am insulating for has a 40,000 sq foot building under construction, each of his waste oli boilers are using 50 gal of fuel a day.
It could be 60 or 16 outside it does not seem to make any difference.

The system is plumbed for constant flow and uses mixing valves to adjust the loop tempratures. Is this normal for a system of this size? I am used to seeing systems that are much smaller(residential) and most zones shut down when the set temprature is reached. What other info is needed? How many BTU's in waste oil?

Thanks

thats a good question, I don't know why not. I think the boilers cycle on and off but the circulators run constantly. There is also some snow melt in this system.

The fuel usage is too consistinat.? I think the system is pulling the slab temp down in one area and transfering the heat to another.

ps only one boiler is currently running

If each boiler is using say 50 gallons per day but additional boiler(s) drop in as load increases AND you have constant? snow melt, it sounds to me like things are virtually ideal...

Once you have insulation load will decrease provided that the snowmelt isn't being used as a "dump".

snow melt as a \"dump\"


Two boilers, insulation is in. We are injecting foam into hollow aluminum window and door frames.

I think the problem with the usage here is the lack of seperation of the zones. The office area is insulated and has low ceilings, the shop is less well insulated and is about 75 percent of the total area and has 20' plus ceilings, then there is the snow melt. It seems that the zones that are up to temp are being cooled by the system transfering that heat to another area? Am I all wet?
