Product Details

A culmination of 25 years of indirect system manufacturing experience. The SuperStor Ultra Indirect Water Heater draws energy from a boiler and thus does not need its own heat source. Hot boiler water flows through an internal heat exchanger in the tank, heating the domestic water. The SuperStor Ultra boasts 3-5 times more recovery than conventional gas-fired or electric water heaters.
  • 316L Stainless steel tank for High Temperatures & Corrosion Resistance
  • Environmentally Safe, CFC Free Water Blown, 2” Thick Foam Insulation allows less than 1/2 Degree F heat loss per hour
  • Immersion type stainless steel control well
  • 1 in. Boiler Supply Connection and 1 in. Boiler Return Connection
  • Needs honeywell control L4080B-1352
  • Stainless steel cold water Inlet
  • High Output Finned Cupronickel Heat Exchanger Provides Maximum Efficiency 11 Fins per inch
  • Attractive silver finish cover that resists dents and corrosion
  • Stainless steel internal Bent Hot Water Outlet Tube – Extracts 5 – 7% more hot water off the top of the tank dome
  • Stainless steel aquastat well

Q:Whats the difference between this water heater and the superstar 45 gal Indirect water heater sto...
by|Jun 29, 2020
1 Answer
Answer This Question

A:  The Super Store Ultra heaters have a life time warranty against leaking; TO THE ORIGINAL OWNER. They were able to offer this type of warranty because they typically last 20 years or more and the average person stays in a home 7 years. But this created a problem for the manufacture because people with failed units that were decades old would expect a new one for free even though the original owner had sold the house decades before. To stop the bleeding the manufacture would often request proof that the person looking for a unit under warranty owned the house the year the unit was made. As I am sure you can imagine going to your town hall and requesting a copy of a tax bill from decades ago is not easy. So the system was not good for the consumer or the manufacturer. Thus a new system has been rolled out and the "N" signifies the change. From now on only "N" units will be offered. When you buy an "N" unit it will come with a 10 year warranty. To make it life time you only need to register the product with the manufacture within the first 6 months after installation. The intention is that this will motivate homeowners to register the product which will make warranty claims easier for everyone moving forward. There is no physical change to the product created by this change. If you still have questions feel free to give me a call. Chris 978 651 3301

    Q:Does this type if water heater use less energy
    by|Jun 11, 2020
    1 Answer
    Answer This Question

    A:  This water heater is installed in conjunction with a boiler. So the efficiency of this water heater is directly dependent on the efficiency of the boiler that supplies it. However I can say with confidence that this technique is generally more efficient. But the real advantages are they last much longer and when part of a well thought out system have more more productive capacity when needed. If you would like to get into the math and have a much more detailed conversation about this versus other methods you are welcome to give me a call. Chris 978 651 3301

      Q:Can I replace a Heat-Flo Indirect-Fired Water Heater, Model 40, with this?
      by|Dec 27, 2019
      2 Answers
      Answer This Question

      A:  An indirect fired hot water heater is essentially a storage tank with an internal coil. Boiler water is pumped through the coil to heat the potable water in the tank. Put differently it is a heat exchanger with some hot water storage. The thinking is that the stored hot water will supply the user while the boiler is coming up to temp. Based on this logic there is typically nothing specific to one brand vs another. So if you have one brand you can typically replace it with another brand. However as a plumber I typically replace like for like for two reasons. First if the connections have not changed it makes the plumbing easier when everything lines up. Second most indirect units have a life time warranty. So typically I am replacing the failed unit with one supplied by the same manufacturer.

        A:  This is an indirect water heater, so without being familiar with the Heat-Flo, I would say probably yes. If your Heat-Flo has a separate zone on your boiler you should be fine and the only other thing to consider is the control. This unit provides a well where a temp control needs to be added. Note that some older indirects had built-in sensors - this does not. Temp control is required to control the zone that heats the water. You can use a control with a short sensor where the control box hangs directly on the unit, or one with an electronic sensor and then the control box can be mounted near the circulator and a wire is run to the sensor placed inside the well. Be sure to use heat conductive grease.

          Q:is there an energy efficiency rating for this
          by|Aug 9, 2019
          1 Answer
          Answer This Question

          A:  Great question. The answer would really depend on the person’s definition of the word efficiency. Trust me when I say there is more than one definition of this term. The one most associated with heaters is AFUE (annual fuel utilization efficiency). If we have a cubic foot of natural gas we know that due to the laws of chemistry and physics that it contains 1015 BTU’s (British Thermal Units) of potential energy. If you were to burn that in the least efficient boiler available by law today, meaning one with an AFUE of 80% you would extract 80% of the heat. (1015 x .80 =812 BTU’s) The remaining 20% of the heat would remain in the flue gas and be wasted. If you were to burn that in the high efficiency boiler I have in my home you would extract 96% of the heat because it has an AFUE of 96%. So the efficiency is determined to be the percentage of the heat the fuel combusting appliance extracts. And indirect fired hot water heater does not burn fuel. Thus it can’t have a typical efficiency. Its efficiency would be that of the boiler it was tied to as it is simply a heat exchanger. So in the first example you could say it is 80% and in my house it would be 96%. That is the long answer and I hope it helps. What I can tell you is that these tanks lose only ½” of one degree per hour. They are built like thermos bottles and have some of the lowest standby losses of any appliances out there. More importantly as I assume your question might stem from a desire to get a rebate, I can tell you most of the agencies that hand out conservation rebates recognize that indirect fired hot water heaters go a long way to saving energy. So even though they don’t burn fuel and have a typical efficiency rating they include them in their programs. However you would need to confirm that with them as the programs are different by area. Also if I lost you in my explanation I am sorry. You are welcome to give me a call and we can talk further. Chris 978 651 3301

            Just 1yr 5 months after installation bottom of the tank started to leak. I believe not properly QC'd their products. I know they provide life time leak warranty but you'd want tanks to last at least a few years. Also, installation labor charges needs to be covered in these case which seems to be a manufacturing defect.

              I am very pleased with this heater. The connectors are very solidly mounted, it is well insulated, and easy to move around. The construction is sturdy and it sits nicely on three furnace bricks. I had no issues getting it hooking up and running and the setup is quiet and bone-dry at all times (five months so far).

                I’m a new home owner so when my water heater started leaking I replaced it with the same brand/model. Best decision ever! My water is hotter than it was before.

                This water heater had two leaks since installed in my home 5 years ago, the latest leak requires a new water heater. HTP won't even offer a discount on a new water heater. Searching other reviews I have seen similar complaints, I would not buy this.

                  when i took it out of the box, i took the top plastic cover off (which comes right off), and there was no insulation on about half the top. i went down to local hardware store and bought a can of spray foam and finished it. but for 1500 bucks? come on! it should of been checked from the factory.

                  I had this SuperStor installed in my house in 1993. It is still working as good as the day I purchased it, outlasting what would have been 2 or 3 regular, less efficient gas water heaters, that leak and cause flooding and additional damage if you're not on top of them. Stainless steel is really wonderful!
