Key Features

  • Gas fired water boiler with cast aluminum heat exchanger
  • Venturi mixing body mixes air and gas providing higher efficiency
  • Designed to operate in low temperature condensing applications
  • Outdoor reset and domestic hot water priority standard
  • Negative regulated gas valve precisely delivers gas to the boiler
  • Electronic control module automatically adjusts blower speed and gas flow rate in response to environment
  • Modulates with 5 to 1 turndown ratio
  • Variable speed motor matches combustion output to heating needs
  • High grade stainless steel burner features quiet operation, high efficiency, and cleaner combustion for low NOx applications.

We carry two manifold options that can speed up installation of the primary/secondary piping required on Ultra boilers. Webstone's Ultra Component kit works with a Hydro-Core manifold and minimizes height added to the boiler. Weil-McLain's Easy-Up manifold kit is designed by the boiler manufacturer and provides the added feature of optional indirect water heater connections.

          Q:

          I have 1660 sq house, I going to used the 80. My house is baseboard with three zones one each floor. In the manual the spec. are 1 inch feed and return, all baseboard are 3/4 inch. will this cause a problem for me. Thank you

            A:

            This wouldn't cause a problem. Keep in mind also that this boiler requires primary/secondary piping, so it would be possible to have 1" lines on the boiler loop with 3/4" lines feeding the baseboards.

          Q:

          Will this boiler works in condensing mode if I use it with cast iron radiators in a single loop pipe or I have to switch to two loops pipe to increase dropping of the water temperature in the return pipe?
          Is it possible that the integrated boiler control will adjust the speed of circulating pump to achieve condensing mode ( less than 120F) for single loop pipe so this way I will not have to switch to two loops??

            Maybe?
            Keep your project simple. If the federal rebate is still in effect; buy the condensing boiler. If not--don't waste your money.
            Hydronics is not an exact science yet. I will be writing a book on hydronic installation in the near future. It will be
            simple and geared to the DIY. The outdoor boiler reset, and primary piping are your best friends if you decide to
            go with a condensing boiler.
            The integrated boiler control is a switch. It will not adjust the speed of the circ.

          Q:

          I am thinking about eliminating my oil boiler and replacing it with propane (no gas available). Can I use a gas boiler and convert it to propane. Are the propane boilers just converted gas boilers.

            A:

            In Weil-McLain's Ultra series, only the Ultra 80 can be ordered as either NG or LP. All other models come configured for NG and must be converted to LP in the field. They include all necessary parts to do this.

            180°F is probably the most common setting, but this can be modified depending on the application.

          Q:

          Hi,
          Why no one is suggesting to get a real Manual J calculation from professional energy experts when people are asking about the size of the unit they need? Nobody should buy any kind of heating unit without an accurate heat load calculation on their house. I have an Ultra II 80 gas boiler with 6 fan coil units (10,000 BTU each) since 4 years, my house is 3200 sq.ft., and the unit is still more than enough for heat. My system temperature setting is on 130F because I try to keep the returning water bellow 120F, so the unit can condensate better also increasing the efficiency. You can't use the "rule of thumb" method anymore. The energy is just cost too much.
          I also think your unit sizing calculator needs some upgrade, it is out of range. I don't understand why I need a 66,000 BTU unit if I'm using low temperature radiant heat, and it jumps up to 115,000 BTU if my heating is baseboard or fan-coil at the same house settings? How it is possible?

          • CUSTOMER CARE

            A:

            Radiant heating requires significantly lower water temperatures in order to achieve the same room temperatures (meaning less powerful boilers). A manual J (heat loss calculation) is always recommended. Any BTU calculator should only be used as a first step or to gauge a ballpark estimate.

          Hi
