  • For use with closed hydronic heating and cooling systems
  • Factory pre-charged to 12 psig
  • Pre-charge should be adjusted to equal minimum operating pressure at tank location
  • Accepts expanded water as system temperature rises to reduce pressure build-up.
  • System connection sets the point of no pressure change
  • Water-tight reservoir for expanded water
  • Sealed air cushion - factory pre-charged and 100% tested
  • Deep-drawn steel tank
  • Air stem for pre-charge adjustment

    Q:

    what is diff #30 and RX-30? If I have both baseboard and radiant, do I need the RX-30 or can I just use the #30?

      A:

      RX 30 is specific to radiant heat. The internal bladder system is plastic ( polypropylene)  and can withstand 200F temps.
      Corrosion is your concern, if you use the wrong parts in Rad heat system.
      #30 rubber bladder system, operating temp 240F, both max pressure around 100psi

  • #30 Extrol Expansion Tank (4.4 Gallon Volume)

    Q:

    I apologize for lack of information about my system. the information on the name plate has worn off. when I bought my house many years ago the expansion tank already was on the system. I have a 30+ year old Weil-McClain boiler system and my house is 1100 sq. ft. and am not sure whether to use a #15 or a #30 expansion tank. the tank I have now is approximately 11 inch in height and approximately 11 inch in diameter and is a 12-lb pressure system with 100PSI and 240 degree max range. the tank is the same size as a 20 gallon propane tank and has worked fine for many years. will it make a difference which tank I buy? thank you, William

      William--You can always go larger without consequence. Too small can cause the pressure relief valve to open to discharge water from the boiler. #30 is the best choice. It is a few bucks more than a #15. There is a formula for sizing tanks. The volume of liquid, density of the liquid,(anti-freeze or water), fill temperature of the liquid and operating temperature of the liquid. Just go with the #30.

      I would use the #30 as long as you have the room ,it may cost a little more than the smaller one but it's worth it since it has more room for expansion and less chance of popping the relief valve, just make sure you get the one for boiler and not hot water heater

      recommend going to the Amtrol web-site and using their calculator for sizing of
      a thermal expansion tank. failing that, you may wish to contact their customer service,
      technical support, and they probably can run their calculator for you.
      it sounds like based on dimensions provided that your current expansion tank is equivalent
      to the S-30, but see caution below.
      1985 data that I used to design my system indicated the S-15 Solar Extrol Tank “...is
      adequate for systems containing no more than five gallons of glycol-based fluid. Model 30
      should be used on larger systems.”
      Caution – the 1985 data also indicates the maximum pressure of the S-15 or S-30 tank is
      75 psi with a max temp of 240 deg F.

      It depends on what the boiler is used for (Hot water, radiators, radiant
      floor heat etc.) Read the following brochure from Amtrol on EXTROL
      expansion tanks.
      From your boiler's BTU/HR rating and what it's used for you can find
      out what tank to order.

      A:

      Expansion tank size depends on total volume of water in the system.
      Most systems use the #30 size unless they are large volume systems like a house with cast iron steam radiators that has been converted from steam to forced hot water. Then you might use a #60 expansion tank. A WGO3 with regular forced hot water baseboard heat would typically use a #30 expansion tank.

      The 15 would be enough for a 55000 btu boiler. You can use a 30 it will not
      cause any problems in operation. They are both a 1/2" ips threads. If it is
      installed horizontally I would recommend that you support the other end
      some how, When the tank gets water in it, can make it sag.

  • #30 Extrol Expansion Tank (4.4 Gallon Volume)

    Q:

    tank about 10 years old. Relief valve opens when pressure reaches 30 psi.
    Expansion tank reads 15 psi and there is no hollow sound on the bottom. Top and bottom feel the same full of water. If so why is water not dripping from the shroeder valve when I take a measurement. Also tank is not getting hot, I assume it is because
    it is full of water and is not accepting the hot water. please comment back in particular when water is not coming out of the valve.

      A:

      I believe you need to replace the expansion tank - it should normally be
      empty and it obviously cannot take more water. I question why the pressure
      is building up to 30 PSI and the relief valve is opening. The relief valve
      should rarely, if ever open under normal conditions. You should check on
      the supply side to see if your inlet valve is working properly. I have a
      shut off valve on my supply and only open it when bleeding the radiators
      each fall. As for your shroeder valve - the pressure relief valve should
      operate first if needed. My shroeder valve has never operated except under
      test conditions and the pressure relief valve has only operated once when I
      overfilled the boiler. I would get a new tank and have the system checked.

      A:

      The design of the expansion tank does not allow water to come out of the
      shrader valve because the water is confined in a rubber bladder. Sounds
      like your tank has lost it precharge. Need to remove pressure from input
      of expansion tank, then add pressurized air through the shrader valve to 15
      pounds or whatever the operating pressure of your boiler is. If pressure
      will not hold, then the shrader valve or tank may have an air leak and the
      tank should be replaced.

      In my tank's case, the water also did not come out of the valve. I knew
      the tank was not functioning because the pressure was going up to 30-40psi
      and the relief valve was working often. Also the sound was dull and the
      tank was cold even with the boiler on. The cost of this tank was only
      around $30 bucks and i just replaced and now the pressure is really nice at
      12-15psi.

      It Doesn't matter. but if you mount it up with the threaded end down you
      need to support the tank so it can't tip sideways. Water goes into it when
      it heats up and makes it heavy. You can even mount it sideways but needs
      supported. But it is best to mount with threaded end up.

      On YouTube you will see some tanks mounted with the opening 'down'.
      That is an improper installation.
      Any air in the system will congregate there and the tank will not do its
      job.
      The tank must be installed with the threaded opening up, so air does not
      gather there.

      A:

      if one refers to the installation instructions for use with Solar EXTROL Expansion tanks, one finds the following:
      “TO INSTALL: SOLAR EXTROL may be installed into a tee or other suitable tapping anywhere on a solar heating system.
      It may be placed in a vertical or horizontal position. It may also be remotely located and piped to a convenient point on the system.”
      For piping and component location convenience and sound engineering practices, I installed my expansion tank vertically in the bottom of an
      AMTROL Air Purger Model #443 with an automatic air eliminator (Part #17130, Solar Components Corp., Manchester, NH) on
      top the purger, for 30 years, with no problems. See attached photo.
      I personally would not mount the expansion tank in the horizontal position nor with the air volume upwards for the simple reason
      one cannot vent all the air from the void against the internal bladder in these configurations.
      With the fluid connection up, the circulating fluid readily floods into the expansion tank against the bladder
      and air is readily removed by the purger / air eliminator (elimination of all air is necessary to allow the expansion tank to function correctly
      [maintaining net positive suction head on the circulating pump] and to minimize corrosion products from developing in the system.
      the above is supported by more detailed install instructions with: “An ideal SOLAR EXTROL installation is to screw it into the bottom of an American Air
      Purger located on the main. This combination offers both a mounting tapping and continuous automatic air removal from the system.”

    I have a 21yr old Extrol 30 expansion tank. what should I be looking for to see if it is on its last legs? tapping on it, sounds dull, maybe filled with water? is it just worth replacing? if so, what do I need to do? turn off the system and drain all the water? then do I need to increase pressure in the new tank? thanks.

    • A:

      21 yrs old--REPLACE it and anything else that may fail, like the pressure regulator, too. You might think of a Filtrol 110, which regulates sys. pressure too. Water expands when heated and it has to go somewhere in a closed sys. The Extrol accepts the expanded water. If water drips out of the boiler pressure relief valve and the press. gauge is around 30 psi. when the boiler reaches max temp., you need a new tank as it is water logged. Unscrew the cap on the bottom of the tank and push on the tire valve if water comes out, you need a new tank. The tank air pressure should be 12-15 psi before installation.

    • VERIFIED BUYER

      A:

      It does appear that your expansion tank has failed and it's time for a new
      one. Hopefully you can separate your boiler water from the rest of the
      heating system. There should be shut off valves on the supply and return
      sides. Close those and drain the boiler. Then replace the tank. The good
      news is it shouldn't take much longer than 30 minutes and the tanks are
      inexpensive. The weak point in these tanks is the diaphragm and once that
      fails (every 20 years or so) there is not much else to do except replace.
      If your system does not have valves to isolate the radiators and lines then
      you need to either drain the system or be quick and have a bucket and mop
      ready. Since boiler water pressure is low it may not be all that bad. You
      should also consider adding valves if you don't have them.

      A:

      I am not a profession but I installed this tank on my own to my baseboard
      heating system. When my expansion tank stopped functioning, there were 3
      indicators: (1) system pressure increased significantly when the system was
      heated, (2) the entire tank, bottom and top, was the same temperature
      (cold) when the system was on or off, (3) tapping the bottom or the top of
      the tank would produce the same sound.
      Since the tank's top and bottom are separated by a membrane, the top is
      filled with water and the bottom with air. Tapping on the top of the tank
      should produce a dull sound and the bottom should be lighter sound. When
      the system is running, the top of the functioning tank should be warm and
      the bottom should be colder.
      To install the new tank, I did not have to drain the entire system. I
      simply turned of the water supply and removed the old tank (it is very
      difficult to remove because of rust). Water came out but I quickly
      installed the new tank.
      The pressure on the new tank is already set at 12 psi. That was the
      pressure for my system (controlled by a pressure regulater set at 12 psi).
      In case yours is higher, you should inflate the tank with a bicycle/car
      pump (see valve at the bottom of the tank) BEFORE you install the tank.
      You can then measure the pressure (before installing the tank) using a car
      pressure gauge.

      A:

      Yes, I have the same problem currently with mine. They typically develop a pinhole in the diaphragm and get waterlogged. With my system the telltale sign is a slow drip leak through the overflow pipe.
      Yes you will have to shut off the water and drain the system, and just read the directions for the pressure setting. You shouldn't have to increase the pressure setting in the new tank as I think the furnace itself will determine the operating pressure which should be in the range of 12-20 psig.
      Also, while you have your system shut down take a look a the other components and see if anything else needs upgrading/replacement. The autobleeder will take care of a lot of residual air when re-filling the system but you will have to open the bleed valves on each baseboard or radiator, unless it is a hydronic pex tubing system.

      I understood that Extrol was for closed looped hot water heating systems. So , I would say No to the question

      A:

      Why use it for cold water? I used it in my heating system for expansion of water during heating process. Generally there is no need for expansion with cold water. I don't know if this has food grade seals either. I don't recommend it for potable drinking water application.

      A:

      The Extrol is for use only in closed hydronic heating systems and chilled non-potable (non-drinking) water systems! A chilled water system is an enclosed recycled water system used for cooling.

      No, that tank is designed for closed hydronic heating systems, not domestic water.
      You want to look for a tank like this:

      It must be for domestic water.
      Make sure it is not designated "For Heating Only".

      That tank is only good for Heating system use. If you want an expansion tank for drinking water then you want the "THERM-X-TROL ST-12 Expansion Tank" SKU:141N43. The ST-12 is made special for Potable water.

      The tank's label says " not for domestic water". But it does say " for hot/chilled systems".
      why would you need an expansion tank for drinking water system? The tank is designed to absorb changes in the water volume, given temperature fluctuations.

      Since the expansion tank uses a bladder, the material is not
      recommended for drinking water.

      It may work for awhile but i dont recomend it. buy a tank for potable water and make sure the tank is presurized for the cut in presure of your presure switch

      A:

      This tank is designed for use only in closed-loop heating systems. The oxygen in potable water can cause it to rust. We would recommend part 141N43, which is designed for use with potable water.

      What is your application? Why do you need an expansion tank on cold water unless you have a check valve on the supply from the street and you have a source of expanding hot water in the system (WATER HEATER)? Are you thinking of a bladder tank with a sys pump (Jet Pump) to boost sys water pressure? If so, look under well systems or under bladder tanks. I guess you can use an expansion tank to buffer surges. If so set the tank pressure to the lowest line pressure encountered. ???
