              Using this tank in a hot water heating system with infloor radiant heat. Last Amtrol tank lasted 15+ years. Another brand replacement tank lasted less than 6 months, so I'm back with Amtrol. hope to see it last another 15 years.

                    Used in a radiant system which is protected with Ethylene Glycol antifreeze.
                    Standard expansion tanks only last 12 to 18 months

                          Look, when you have a NON-BARRIER tubeing system it's ok. You just have a high oxygen content. You MUST USE All and I mean ALL non ferrous componets. This is the golden rule. The RX Radiant Extrol Expansion Tank by Amtrol is designed to protect you from oxygen. Don't forget it.

                                            The RX-30 is best for long term use and with Eichler Homes in general. The 102-1 does work, but the liner makes it last longer and perform better. I would recommend using this over the #30 extrol as a general practice.

                                                  I installed this tank on my radiant floor heating system boiler. Apparently the tank that my boiler installer had put on it originally 13 years ago was not suited for radiant floor systems. I had replaced the original rusted expansion tank with the same type, then it rusted from the inside also, after about two years. I did my research and found that it was the wrong type tank in the first place, so I found this RX-30 model on your website and knew immediately what my problem had been. We'll see how long this one lasts, but I am confident I have solved my problem.

                                                            A:

                                                            In general, no reason it won't work. There are two key items to pay
                                                            attention to; maximum temperature and system volume.
                                                            The maximum temperature rating for this tank is 200 deg F, which is likely
                                                            fine if your baseboards are hot water. If they are steam then this is not
                                                            the correct unit (not just based on temperature).
                                                            Sizing of the expansion tank depends on the volume of your system,
                                                            baseboards are probably lower in volume than most radiant systems, but that
                                                            will depend on the exact system. The PEX Supply site actually has a handy
                                                            calculator here:
                                                            http://www.pexsupply.com/pex/control/ExpansionTankSizeCalculator
                                                            that will tell you the size tank required based on your boiler size. If you
                                                            enter baseboard as the heat type it will probably assume steam, and point
                                                            your towards a higher temperature rated unit. You can either just go with
                                                            the unit it points you too, or, use the size of that unit to find another
                                                            brand/style that fits your needs.
