    I wonder how it compares cost-wise to the components it replaces. There's an obvious labor savings to take into account as well.

    What happens when the expansion loses its charge? That's a whole lot more work to replace that......

    Hmmmm. Where is the point of no pressure change now ?

    I looked at the website.
    They say its replaceable....
    Definitely is thinking outside of the box.

    Inovatve idea. However I think modular, and if you lose the bladder the hole thing needs replaced. So the cost of it verses separate components comes to the labor cost savings. That, and someone who doesn’t have the ability to properly place the individual components in the system. This makes it easy. Pump away on the return, or pump away on the supply.

    It does take away the ability to pump away on the return which most mod/cons prefer, and have the air removal on the supply where fluid is the hottest to facilitate optimum air removal.

    Then throw in the hydraulic separators which have become the multi purpose tool in the system.

    Clever idea.
    It must have 4 penetrations into the bladder, for the valve, connections and air vent?

    And for mod cons that require that you pump into the boiler, as Gordy mentioned?

    It's certainly not a catch-all, but it could be a useful product to have available.

    As long as repair parts are still available in 5- 10 years from now?

    A rebuildable device with no parts down the road is ??

    I certainly think it could clean up certain installs. Again know where, and when to use it.

    Back to modular components. I guess the way would be to have some in the truck, and swap out. Then rebuild at your leisure rather than on site. Seems the tank with multiple bladder penetrations as @Hotrod pointed out is the most vulnerable.

    Only two tank volumes also..

    That's true. There's always a certain degree of risk when taking on a new product. Some stick and some are a flash in the pan.

    Never the less, it is good to see this type of creative innovation in hydronics.

    The iso flanges with the pressure gauges and the stainless flow-thru design DHW expansion tank are clever products that they manufacturer also.

    The biggest challenge for these small "boutique" manufacturers is getting into the market at a level that can sustain the business and turn a profit.

    Also the chance someone else knocks it off and drops the price.
