Buffer tank control for efficiency
I have a customer who is sending a heating package out to the interior, and I need to put this together to be able to send. I have figured the usual things, but am stuck on the best way to utilize a buffer tank for overall best efficiency. I am thinking of using a Tekmar 256 control to keep the tank at temperature, and a mixing valve on the outlet to go to the radiant system. My brain is really tired right now and I am having trouble with this.
The boiler is a lower mass oil boiler, but rated at 140,000 btu input. The boiler has to be this one. The radiant is 4 zones, and one can be as low as 2000 btu's, so the need for the buffer. I am concerned about having the tank at 140 degrees or so in order to keep the boiler from condensing, but I don't want it to have to be at that temperature when the outside temperature rises. I would love to be able to just keep the tank at whatever temperature the heat needs, but I don't see how I can do it without the boiler condensing.
Any thoughts are much appreciated at this time.
