PIPEING OF BIOLER

RICKY SOPER

I HAVE TWO HYDROPULSE GAS BOILERS AND A LARGE INDOOR WOOD BOILER PIPED TO ONE MAIN LOOP IN A DENTAL CLINIC. THE PROBLEM IS THERE IS ONE CIRCULATOR ON THE RETURN LINE THAT RUNS WATER TO ALL THREE BOILERS. WHEN THE VALVE TO THE WOOD BOILER IS OPEN THERE IS INSUFFICIENT FLOW ACCROSS THE TWO HYDROPULSE BOILERS TO CLOSE THE FLOW SWITCHES. IN THE PAST THIS WAS NOT A PROBLEM AS THEY WOULD ONLY OPERATE THE WOOD OR THE GAS SEPERATELY. NOW THEY WOULD LIKE TO RUN THE WOOD DURING THE DAY AND LET THE GAS BOILERS TAKE OVER AT NIGHT WITHOUT HAVING TO MANUALLY CLOSE AND OPEN VALVES.
WHAT DO YOU THINK ABOUT THIS: USE THE WOOD BOILER AS A BUFFER TANK/PRIMARY LOOP IF YOU WILL? THEN INDIVIDUAL PUMPS ON THE TWO HYDROPULSE BOILERS, (WHICH ARE CONNECTED TO AN ALTERNATING TEKMAR CONTOL FOR EVEN RUN TIME)SENDING WATER TO THE WOOD BOILER TO MAINTAIN A WATER TEMPERATURE. THEN INSTALL A SECONDARY LOOP TO PUMP AWAY FROM THE WOOD BOILER TO THE CONDITIONED SPACE? WHEN FIRINGTHE WOOD BOILERIT WOULD MAINTAIN THE TEMPERATURE ITSELF. ONLY WHEN THE FIRE GOES OUT WOULD THE AQUASTAT ALLOW THE GAS BOILERS TO FIRE.
WHAT DO YOU THINK????

I'm not YELLING (caps lock)

Just wanted to know if using the wood boiler as a buffer tank was a good idea??
Usually buffer tanks are just that-a tank-but this has its own source of heat (the wood fire).
If the wood maintains the water at 180 degrees and the Hydropulses aquastats are set below this so they do not turn on until the wood fire goes out and the water temperature falls below the Hydropulses aquastat setting.
