What are good options for a Indirect DHW hook up with Viessmann Vitodens WB2B 26?

absorbtu Member Posts: 8
I am thinking about a Smart 40 rather than the more than twice the price Vitocell 42. Is this a good choice or are there compatability issues? I know the larger Smarts want more GPM than the boiler (74k BTU/hr and 6.2 GPM max) can deliver, so I am leaning toward a smaller tank since there are just 2 adults. How do you justifiy the higher price for the Vitocell? Higher efficiency? Better warranty? Is it really worth it? Are there better alternatives for an indirect DHW?

    Indirects with Vitodens

    There is no better indirect manufactured than the Vitocell 300 series. Better materials and unconditional warranty. If budget is an issue, we recommend the Triangle Tube Smart 60 tank. The tank will need a separate pump, per the Viessmann schematics, and needs to be installed correctly, which will depend if you are using the low loss header.
