Boiler selection for summer home
I have a friend with a summerhouse in cold northern Maine which is closed in the winter. The boiler is winterized when the house is closed(pipes and boiler drained, and antifreeze in traps etc). House has a granite foundation, and basement is a combo dirt crawl space with a cement area where the boiler is located.During summer the basement is dry. In the winter there is spring thaw creates a small flow of water in the basement to the old drain in the floor not to mention the condensation from warmer humid air hitting the colder metal components. Boilers which remain hot all year can last 40-50 years, boilers in the above condition last up to 10 years.
My question is how to protect the boiler from corrosion etc. while it is stored the winter.
Should I build a room around the boiler and controls and vent the space?
Would draining the heating loops, and running the boiler a very low temp(120) work? (use oil in winter)
How about fill the system with PG and use electric to heat the loop at a low temp(above ambient) to keep the system dry and keep condensation away?
Any ideas which experience shows to work?
Re: Boiler selection for summer home
Your first step perhaps should be to consult the particular owner's/operations manual for the brand & model of the boiler in question--they always give detailed points that should be followed for long-term and short-term boiler layup; long-term layup (over 30 days) is known as DRY LAYUP or EXTENDED LAYUP,or EXTENDED SHUTDOWN.
If you don't have the hardcopy of the boiler manual, you can usually find it on the internet via Google; also Google such terms as "boiler dry layup", or "extended boiler shutdown"--there are specific chemicals that are recommended for each brand of boiler, sold at boiler supply parts outlets ; the other option would be to consult the Yellow Pages under "Heating Contractors" and call a number of local contractors until you find one that is familiar with long-term boiler layup in wet conditions, and the procedures & chemicals used under specific conditions.
The boiler mfgr usually has an 800 number that you can call to speak to the technical dept. who can advise of the steps to take to do a long-term layup of their product----Google the brand name of the boiler to get the boiler mfgr's website & phone number.
