Aquastat at 140-200F?, if you have your boiler set to be standing by at 140, you won't make much 130F water for the shower. If the boiler comes on and never gets it hot again, your coil may need de-liming. The indirect water heater is the way to go. I think you are misreading about having a storage tank without an element. The water has to be reheated once it cools in storage. Some run the water through the boiler coil first and if happens to be hot, it preheats for the electric. If you have a flow limiter on your DHW line and you don't get enough, your boiler is too cold, the coil is insulated with minerals or you have a mixing valve blending back too much cold to temper it. The indirect stores the water at a cooler temp than blr, the chimney isn't pulling heat off the storage, the fresh water (with more minerals) is seeing a larger and cooler surface for less scaling, no mixing back waste, less scalding risk as storage is at safer level.
