my workshop gets very cold and frosty somebody said that you can put antifreeze in the boiler water and fill it up as antifreeze takes the oxygen out of the water and helps to stop corrosion . or is it best to leave the boiler as dry as possible with all the plugs out . this is our first winter at shutting down our engine and we are trying to get as much information as we can .many thanks mick and Claire.

Hi

I lightly steam Crystal to 60psi.
Fire burnt out but left in the grate.
Blow down fully.
Immediately remove all plugs and piston and valve covers.
Leave until next day. Boiler inside should be completely dry by now. I borascope the boiler to check.
Dry any lingering condensate.
Refit all boiler bungs.
Oil up the valve timing chests and cylinder bores as far as possible and replace covers.
Brush tubes with the stainless steel brush.
Remove grate and wire brush down the firebox.
Wire brush front tube plate and smokebox and as much of chimney.
Suck all tubes and smokebox with ash vac. Ash if damp can become corrosive.
Lightly oil both firebox and smokebox.
Motion left oily from last steaming or cleaned and re oiled.
Pressure gauge removed and stored in house against frost damage.
Mechanical water pump glands cracked open and drained.
Clack valves opened, dried out, put back together.
Steam injector all pipework loosened off and dried out.
Tender and Belly tank drained and wicks installed to get the last dregs out.
60w 12" bar heater in firebox with grate and ashpan installed. Damper closed.
Rag over the chimney top to reduce drafting.
2 x 60w 48" bar heaters under the engine on theromostats. One at 1degC the other at 4degC.
Cover with canvas engine cover.
Cover with old bed sheets as dust cover.

Night Night. No problem for the last 4 North Scotland winters.

The Paplewick pumping station in Nottingham keep all their boilers brimmed when not in steam. This stops oxygen getting to the boiler and rusting it, as it is likely even when empty to have a high moisture content. they claim there has been very little corrosion after more than a 100 years of using this method.

I would like to leave water in our boiler but my workshop is very big and gets very cold and frosty how do they stop the water from freezing . I cannot keep the engine warm .

A single light bulb in the firebox would be enough, an old sleeping bag over the top would help as well. Greenhouse heaters are good as well as they can be set to come on when the air gets down to +2 or 3 degrees C.

Hi,

Just a (maybe) dumb question: I followed above suggestions and winterized Pied Piper. While putting a 60W light bulb into firebox I was wondering what it is good for? With a boiler full of water I understand to use the heat to keep water from freezing, but at an internally dry   boiler with the inside closed of?

Just wonderung Question

Cheers

Hi Elwood

The gentle heat in the firebox stops the metal from sweating or creating condensation as the air temperature changes at a different rate to the metal. So any soot deposits do not turn in to an acid.

Hi Lynn,

Thanks for that info. So it‘s more to control the humidity of the „outside“ i.e. firebox, inside of tubes and smokebox and less for the inside means water wetted area. You never stop to learn.

I have a similar problem to many others. The garage I use for storage is standalone, which means cold and damp in winter.

My solution is also similar to others. I use two 100w bulbs wired in series and placed inside the firebox, which creates 50w of power consumption.
The bulbs are left on 24/7 and because they are each running at 25% power level they have so far lasted 4 winters and will probably last forever.
[A single bulb running at full power can't be relied upon to last and of course replacement filament lamps are difficult to obtain these days]

I cover the whole engine (with dry boiler having blown down and left all plugs out) with an old duvet and the 50watts of heat ensures the external engine surfaces stay just a few degrees above the garage ambient at all times. Therefore condensation forms on other objects and not the precious engine.

Hope this helps.
