[CNM Design]

I have a hot water boiler system now. Baseboard radiant heat. Will be changing to in floor later.

Max temp is 180, minimum is 120 and then the gas kicks on.

Circulating pump runs 24/7 so not to let the left over heat in water go up the flu when pump is off.

Gas does not run 24/7.

Stove must run 24/7, can not turn off and then back on when heat is called for.

Am I correct in assuming my over all goal is to keep the temp in the gas boiler from dropping below 121?

Second goal is to find the btu out put from the stove required to maintain a water temp in the gas boiler of at least 125 or 130.

I think pumping 125-130 24/7 should be ok.

Third goal would be to determine a flow rate for the fuel (pellets) and then design a feed mechanism capable of sustaining that rate.

If for some reason the fire goes out or fails to provide the btu’s required to maintain 120 in the gas boiler, the gas boiler will take over.

Is it all this simple or am I missing something?

Can’t see myself building a stove just to build a stove. Need goals and requirements first.

Could mean the difference of several thousand btu’s in fuel cost a month.
