I've been trying to search this website for storage tank ideas and feedback.

Has anyone had success with a storage tank on a 520?

I have a large system and i'm thinking of adding a hot water heater as a storage tank to increase the volume of the hot water storage. Any thoughts?

Stored hot water loses its heat. Then you have to re-heat it.

I'm doing that now, but I have it plumbed in incorrectly. Because of that, I'm not sure whether it is a good idea or not.

I do have a crossover plumbed into the system so I can disconnect the storage tank during the summer months when I use my boiler for DHW only.

I'll be re-doing the system in the spring to correct my return issues along with a few other things, so I'll have a better idea on how well this works out next heating season.

The $64.00 question is why? Do you have periods of peak demand where the boiler doesn't keep up?

My guess is he needs to move a lot of water in his system, and that is causing either shock or slow recovery times.

I kow that is what happens to me.

boiler shock --- or the possibility of and slow recovery are easily over come by system balancing

energy storage in a wet system is best left to the wood burners that cannot control their appliances -- except for full burn or no burn

Are you talking about storage for faucet type hot water or for heating the house water?

Those wood burners would be the boys who run the gasifier wood burners...by design, it burns fast and furious and then fire is let go out...it is not a design flaw...hence the need to store that heat for later use. Just a FYI :)

My concern was to store water for the heating system.

I feel like i'm still burning to much coal and feel like the system is getting shocked. Right now I am running a honeywell 7224 triple aquastat and have my current temps set at 150 low limit with a 10 differential and high limit at 170 with a 10 differential. As of right now my boiler maintains a 140-150ish temp and every single time that there is a heat call from the thermostat, it triggers the ciruculator to run AND the stoker.

So I guess what i'm asking is does it make sense that the stoker runs everytime that the circulator kicks on? in my mind i'm thinking that the stoker should only stoke when the temp drops below the low limit and on the timer that I have set to run 2 mins every half hour to prevent outfires. Just seems like it runs way to much and i'm losing heat up the chimney.

How many zones in this "large system"?

An indirect HW tank is the best for storage ... BUT ... BIG $$$$$$$ just for storage. :shock:

My tank will only lose 7° in 10 hours at 176° ... and that's using the hot water to rinse dishes too. Great insulation in there - wish I could make my house that tight ... :lol:

okay so turn up the aquastat to what? Should I adjust the differentials? Does it make sense that the stoker stokes every time there is a call for heat? It just seems that it there should be times that the heated water in the boiler is enough to satisfy the heat call without the need of stoking...

Mine works pretty good, but I've got a bit of water in the system. I figure the oil boiler holds 15-20 gallons, and the stoker boiler holds all of 15 ... maybe more. Just the way it worked out. I just wanted the stoker to replace the oil burner - that was my main goal. It has done that, and I'm VERY happy. ;)
