AntiFreeze Tank

SWS2

Have an oil / hot water system in a seasonal house. In the winter I drain house and turn the well pump off to prevent freeze up in a power outage. Does anyone know what type of a pressurized tank i can hook up to the boiler feed with with an antifreeze solution (already have antifreeze in heating system). I dont use well water in system anyway due to minerals. I was thinking of a bladder-type well tank, but really just need a 5-gallon plain tank i would fill, pressurize and monitor with gauges. Have low water cutoff for safety also.

here's what I do alot. From the line tee in order, isoation valve, feed valve, pressure gauge(0-100), boiler drain, #30 exp tank(sometimes larger).

Dischare air from tank, fill tru boiler drain, repressurise tank to 100#.

Sometimes in way off places I valve and union so client can bring to me for refill. Which as we all know shouldn't be very often after initial burping of system.

Thanks for replies. Any idea how much the axiom tank goes for, looks kind of expensive. I was leaning towrds making my own anyway. Think expansion tank with bladder is better than a pressurized holding tank only?

Thanks steve gates

Thanks for info, purchased items today to make one. One question, how would you know if its empty. Pressure would lower a little, but not completely, correct?
