Summer Layup and Waterside Treatment

This is the first year with the EFM. It worked out much better than I anticipated. I plan to shut it down for the summer and use a heat pump (add on) hot water tank for domestic hot water (it doubles as a dehumidifier and air conditioner believe it or not). For longevity, I would bet that keeping the EFM hot would be best (to keep moisture/corrosion from building up on the fire side). My question is what are the best steps to take for summer summer cleaning and layup? Are there any good threads you could point me to? I'm wondering if any treatment to the fire side is recommended.

My plan is to first do a thorough cleaning of the boiler and pipe. I will even have the chimney swept. Any other treatment for the gas side recommended?

I'm also interested in any recommended treatment for the waterside. I've been trying to find Silver King Formula #5 online and had no luck. Does anyone recommend any treatment? If so, where can I buy some? My plan is to layup the waterside wet. However, I'd like to put some corrosion inhibitor first.

Any info would be greatly appreciated.

I have to check to see if we can get the Formula #5 back in stock.

I would thoroughly clean the deposits from the inside, as you said, and then disconnect the flue pipe so the chimney doesn't suck moist air through the boiler all Summer. Maybe a light bulb inside for some warmth. Check for water leaks.

I also used my EFM 520 for the first time this past year. I installed in in July 2008.

I have an oil burner that I can run this summer...Or...I can keep the 520 running for domestic hot water. What would be the best thing to do?

If I keep the 520 running for the summer, should I be cleaning the stove and chimney, and what's the best way? Is there a thread in the forum I should be looking at?

Thanks,

The oil boiler is probably more efficient, but may cost more in the long run than coal.

You should clean your 520 anyway. Brush out the inside, empty the pot and clean the holes in the plates and under the plates. Clean the chimney base and flue pipes. I would also disconnect the flue pipe from the boiler for the Summer.

I've seen a small lightbulb inside the boiler for a small amount of heat to keep it dry.

It's better to keep the unit running, even at the lowest setting on the aquastat. Check for water leaks and fix ASAP. Snug up the coil nuts, if necessary. Do not overtighten.

It's imperative you clean out the flue pipe and the bottom of the chimney. Fly ash will accumulate in both and eventually block it preventing the gases from escaping then you get dead. I try not to beat around the bush where this is concerned

Use a mirror to look up the chimney itself to make sure you have no obstructions but you don't need to clean it. If you want to feel safe do it every decade or so..
