buffer tank running boiler

Also...

All zones circulate the same supply temp, Tekmar 352 with OR, which has never exceeded 125F.

Joe,
Yes, the HeatManager is a "fancy differential", but it is a "dynamic differential" (not fixed). It monitors the water temperature leaving the boiler 3 times a second. The idea behind the 3 times a second is to watch how fast or how slow (the rate of decline or BTU shed-rate) this temperature is changing. It will hold the burner from firing based on this change and can see if that decline rate changes..

The HeatManager has been watching this rate of change and has calculated a burner start-point if 152 degrees F. This rate of change suddenly becomes faster (another zone calls, etc.) and the HeatManager sees this via the sensor and recalculates the burner start-point for 158 degrees. This is how the HeatManager works.

Outdoor reset controls rely basicall on one thing...outdoor temperature. Most of these controls are not "profiled for the site where they are installed and the outdoor sensor is rarely on the north wall and protected from the sun...but this can be compensated for............how?

By relying on the outdoor air temperature to decide what the boiler water temperature should be, the controller knows nothing else about the space ie: how many people are in the space/s, is it sunny or cloudy out, is there a big solar load helping the south side of the building, did someone leave a door open?

The Beckett HeatManager can answer all of these questions by using one sensor (heaing only application) on the supply pipe of the boiler.
The measured temperature drop at the boiler supply pipe by the HeatManager sensor (rate of decline) is directly proportional to the BTU shed-rate of the boiler. More solar load, more people, etc.....slower shed-rate. A door left open....faster shed-rate. This rate of change is monitored constantly at 3 times a second and the sensor can detect any sudden changes and re-calculate a new burner start-point.

Using an outdoor reset control...what ever it has decided the water temperature to heat with should be is what it will be....whether its good or bad.

We work as close to real time as possible...3 times a second.

A buffer tank is nothing more than a storage tank, and the water in it has to be reheated.......and is not doing the same as the HeatManager. Its acting as a vessel, to help with the heat load. The burner must fire sooner or later, and that is where the HeatManager comes in. A buffer tank helps reduce burner cycling because of the water mass stored inside.

i had a similar conversation this morning...

my thought is .... when the boiler fires the boiler circ makes,...the zone(secondary or injection pump) if calling returns cooler water into the boiler return ,...this in turn causes a longer burn cycle on the boiler consequently a longer run time on the burner and boiler circ....

my buddy says uh uh nope,....

what if the boiler is staying hot and there is a short cycle between the closely spaced 'T's?

well, good question.

something would have to relate to the boiler circ that the low limit of the zone had been reached and get motivated....that would be a sensor at or near the return of the two closely spaced t's.
