We want your outdoor boiler to last 40 years or more. And it can - as long as you do proper maintenance. During the part of the year when you are not using your boiler, you must do the "Summer Shutdown Checklist" (click HERE for complete checklist).
While all the items on this list are important, the TOP 3 MOST IMPORTANT items are as follows:
1. Remove the ash
2. Fill your boiler completely full of properly treated water, and send a water sample to be tested by the Hawken Lab.
3. Perform a sediment flush
ASH - If you don't remove the ash from all steel surfaces, the summer humidity will get absorbed by the ash and it becomes a caustic paste that will eat your steel. Remove it from the boiler burn pot, and all other surfaces.
Do NOT forget to remove the chimney cap and clean out the chimney area with a wire brush, and shop vac out everything you can. Steel surfaces MUST NOT be covered with ash during the humid summer months.
WATER TREATMENT - If your boiler water is not properly treated, it will start to look like the inside of the Titanic, but much quicker. Remember the scenes of the Titanic when they discovered it with robotic submarines? We have seen the inside of your untreated boilers and it is NOT pretty!
Add the proper amount of water treatment, and SEND IN a water sample to the Hawken Lab! You can ALWAYS call us with any questions you may have, or check out our website for the FREE Water Testing Section FAQ HERE.
SEDIMENT FLUSH - Sediment is the "Secret Killer" of outdoor boilers. You must flush it out of the bottom of your boiler at least each year by simply opening the drain valve for 5 seconds or until it runs clear.
Then, every four years, you must drain the boiler completely, and flush it out. Follow our complete FLUSH Instructions at this link HERE.
Again, the entire Summer Shutdown Checklist is a very important set of maintenance standards that must be kept if you want to get the most savings out of your outdoor boiler, but these TOP 3 items are the most critical. If you stay on top of these critical items, you will Keep Your Family Toasty Warm and Comfortable for Decades!
