Gasser burners with storage and boiler in outbuilding

[NCFord]

What do most people do with the loop going to the house from storage? It's either run 24/7 or on a call for heat? And if it's not 24/7 then how can you heat DHW?

You can heat DHW with a heat call, same as the other heating zones call for heat. But I don't have storage outside so not sure how they're doing it.

Is your storage pressurized? If so you need a side arm which would be kept up to temp by a circulator and a control.

Or a flat plate.

Deep Portage has this arrangement with its Froling with 1600 gal of storage, and it uses a flatplate exchanger, of a type used in solar hot water systems. The dhw storage tank is an electric hot water heater. The electricity is shutoff during the heating season, and then back on again during the non-heating season.

I have a boilermate DHW tank that runs like another zone, has it own zone valve that opens and closes as needed to pull heat from my 500 gal. of storage in an outbuilding.

Only when there's a call for heat.

That's my setup too. Except I have a sidearm & flatplate in series - started with the sidearm, added the plate & just left the sidearm where it was. I use a B&G E3ecocirc to circulate on the domestic side of the plate, it is wired through an RIB relay that gets activated when a Johnson A419 calls for heat by opening a zone valve on the supply side of that zone loop which then sends the start signal to the relay when its end switch closes.

Thanks, i would think a flat plate would be alot faster than a sidearm when not running 24/7.
