Im not really interested in an electric water heater. I want use my boiler for heating my domestic water. Which would be better, a storage booster tank using my boiler tankless coil to heat the water or an indirect fired hot water storage tank abandoning my boiler coil.

Also would it ever be a good idea to use an indirect fired hot water storage tank using my boiler coil as well as the coil in the tank for heating the domestic water, or is there a loss that would make this not a feasible option.

    Hot Water Storage

    I have a boiler with a tankless coil. I'm considering adding a hot water storage tank to improve my domestic hot water distribution. Which is the better way to do this? Should I install a hot water storage booster tank using my tankless coil in my boiler to supply the hot water or would it be better to abandon the tankless coil in my boiler and install an indirect fired hot water storage heater?

    Any suggestions are greatly appreciated.
    Thanks

    If ? ? ?

    You have water that is not making a lot of deposits as it is being heated, an electric water heater (cheap) can be used to store water from a boiler coil. If the water is making a lot of deposit , Use an indirect heated tank. Either way, a pump is almost always needed, The control on an electric W/H can be used to run a pump.
    Good luck

    HTP for their AB tanks. They can be made of stainless or glass lined and will definately outlast the boiler.

    Initial cost and install will be less than shifting to an indirect, and you can lower the "protect" limit on the boiler. For cost comparison, check out Everhot. They make a quality tank, and it is usually sent as a package . The circulator and control are included.I highly recommend following their piping instructions, and passing the cold water through the coil before letting it go to directly to the tank. (a swing check is a small price to pay for quality hot water)

    I installed one in my parents home when I changed out the boiler. My Mom always complained about the time it took to fill a bath tub. After shifting to the storage tank,they have no complaints whatsoever.
    Having installed many of the booster tanks in the days before controls caught up to the present stage, I feel it is a cost effective and prudent investment for anyone using a tankless coil at this time. (one thing to not forget is that the boiler with a coil hasn't been run cold, and the surprises that come with "cold start" in this case can easily cost you a boiler too) JMHO Chris.
