Draining boiler in winter
« on: February 16, 2015, 06:24:39 AM »
I need to drain my 1450 for a few months. It will be shut off so I'm draining it to prevent freezing. Anything special I should know or consider before doing so?

Thanks,

Drain it completely, blow out the lines and add anti freeze to the lines to protect them.

Thanks slimjim

I planned on draining as much as I could from the unit outside and then draining the rest of the lines from the sillcock in my basement.  not sure how to blow out the lines with my setup.  Do I need to take apart the lines where they come into the boiler?

Also, will draining the water create any issues with rust inside?

Thanks again

I would probably take the pump out and if you have a check valve on the return line i would take the cover off to get the water out of it

If you can't get all the water out of the lines, I would try to fill them with RV antifreeze.

A utility pump, washing machine hose and a 5 gallon bucket makes an easy setup for getting rv antifreeze into your lines. If you have valves in the basement so you can send a slug down each line to the boiler you can give them a shot of air with a rv hose adapter. I've got black plastic lines laying around my campground that I winterize with a setup like that.
