3 Pass or System2000

Rocky_3 Member Posts: 232
Are you on well water or city water? The only thing I have had an issue with on the EK is hard water plugging the flat-plate heat exchanger. They are amazing heat exchangers, but the passage ways are so tight that hard water will quickly plug them. If you have hard water, install the hard water kit with them (basically a zone valve on the HX line). Otherwise I think you will love the EK. Quiet, efficient, easy to service. Make sure a combustion test is done on start up and the results recorded and sent in to EK with warranty card. Enjoy your new system, and please, post fuel savings here next year after comparing degree-days.

    Feedback on both types of systems ..

    Everyone .. thanks for all the feedback. I'm replacing my boiler .. Weil 68 about 20 years old. Have 4 zones and baseboard heat in a 3300 sq ft home. Home is insulated well, put in new windows last year and oil usage dropped from 1300 to 1100 gallons. I need efficiency. The EK2000 and 3 Pass systems (MPO,Biasi,Solaia)are what I am now considering. I've heard rave reviews on the EK, and good things about 3 pass systems. The size of the system is somewhat of a consideration ... I know you guys install these systems .. what's your take? I want to make a decision by Friday .. Thanks for your help!!

    as a thought....

    Insulation in the Lid might be money well invested. the numbers seem a bit different for 3000sq ft. consider having a professional insulator stop in for a site appraisal.

    Might also consider some form of controlled ventilation ,maybe a slight positive pressure within the envelope ....sufficient make up air in the boiler room specifically for the appliance... just thinking...nail down some of the corners ...

    that way ,efficiency of a heating source might actually mean something. A professional heating contractor who cops a visual at your home might be another good idea...you may not be aware of some other defugalties in your home that would be best controlled by strategies that don't involve over heating the planet to keep your home in a comfort zone that you can "Live with".

    Solaia, good value, cast iron, I say

    Solaia,I'm a big fan of these. From both installion and most important in my eyes annual service, + all standard parts(including controls) that just about ANY service truck would have as stock if ever needed. Fact is I'm pulling out a 7yr old unit(won't say name here) from my own house to install an Solaia SL4100 to cut fuel costs. John@Reliable

    I've only done 3-pass boilers

    (the Solaia is our favorite too) so I can't speak to the System 2000 unit. But we have had plenty of recommendation on your threads for the System 2000 also. I'd say at this point, you can't go wrong either way, as long as the unit is chosen, installed and serviced properly.

    And at this point, I'd like to ask a favor: Compare the fuel usage of the new boiler with the old Weil, over the course of a year, on a gallons per degree-day basis. Post the results on the Wall next year. We'd love to see the difference!

    system 2000

    Just spoke with a installer .. Looks like the EK2000 is my choice. Not saying that the 3 pass systems aren't as good, but I need more space with them. The flue is in the rear of the boiler which means it will have to come out further from the wall. Will take up too much space as the room doubles as the laundry room. Anyone with tips on things I should look out for with a EK2000 install I'd love to hear it.

    Hard Water

    I have a well and I do I have hard water. I've installed a water softer/sanitizer a few years ago, and it seems to be doing the trick. But thanks for the advice .. I will have the combustion test performed ..Please let me know if anything else comes to mind.

    your systems 2000 boiler installer is likely to be well aware

    of any and all minor technicalities. Yet, i have seen some installed that had the appearance of an installation done by someone who found it in a recycle refuse area...your contractor /service/installer will generally keep up with new product advancements meaning they attend classes,read, study and consider their installations a reflection of the quality that they offer...

    something that i have seen a time or two is some gell globs in the water storage tanks....dont worry, it is covered under the fact that it was in a tank that was over 20 years old *~/:)
