I picked up a Crown mega-stor tank to use with a Lochinvar WH55 boiler. Lochinvar sells a temp sensor/thermistor with their indirects that couples with the boiler controls. The mega-stor comes with an aquastat.... and while I can wire the aquastat to the boiler, I'd prefer to use a thermistor (utilize boiler controls).

The tank's immersion well is welded and appears to be for a 3/8" bulb. The Lochinvar DHW thermistor is 1/4" and incorporates a high-temp limit (2 wires) and a tech said its a 10k NTC sensor.

I see Honeywell sells a couple 3/8" thermistors, a single element 10k NTC (2-wire) and a dual element, limit temperature
sensing function, 10k NTC (3-wire). Anyone utilize thermistors with their mega-stors?
