HELP! New Heating System

I am debating between two proposals and any insight is helpful.
1) Buderas G115WS/4 with Riello Burner and 40 Gal. Bradford White indirect water heater. Using 3 zone valves for the two zones and the indirect. Spirovent air elimination. Installer is a small 3 man show who also did my BOSCH AC/Heat pump this past spring. Work was quality and efficient.

2) Viessmann VITOROND VR-1-27 92 with Riello Burner and 35 Gal Vaughn indirect water heater. Using 3 circulators for the two zones and the indirect. Honeywell (super??) air elimination. Installer is my oil company with mainly 5 star Google reviews. Cost is $200 less than option 1.

All other work and accompanying parts are on par with each other.
Not sure if there is a wrong choice, but maybe there's a better choice?

    Flip a coin perhaps but in general go with the Co that has better service. Your oil co is geared for after hours right?

    When everything’s equal go with what you know. if The first guys did a decent job for you previously I’d tend to favour them. $200 is nothing in the grand scheme of things what a heating system costs.

    As someone that works for a smaller company,

    Small companies that have loyal repeat customers , get special treatment. If they did good work before they will likely do good work again. The bigger guys are probably fine but less of a guarantee.

    That being said, zoned circulator tend to be
    Better than zone valve setups for reliability and performance, but cost a bit more. Might see if option 1 will upgrade for a price.

    Go with who you trust, as opposed to the equipment.
    I'm not familiar with the Viessmann, and love the Buderus, but the installer is the deciding factor.
    Was a heat loss calculation done by either contractor?
    With either boiler, I would look into a BF Riello. Much quieter and brings in outside combustion air.

    The installing contractor makes or breaks a System.
    On Line Reviews are worthless.

    Id prefer separate circulators over zone valves!

    Agreed Has a heat Load / Loss ben performed?

    Both are quality boilers, although I am not the biggest fan of Riello oil burners. If money was no object I would install an Energy Kinetics boiler in my house. I would look into if anyone in your area is an EK installer.

    Both Spirovent and Honeywell Supervents are great products. No new boilers should be installed without a micro bubble resorber air eliminator in my opinion. Make sure that your new boiler is installing the circulator pumping away from the expansion tank! This is critical for proper operation and air removal.

    My experience with Buderus has been excellent! Riello, Excellent! Bradford White, great!
    Not much experience with Viessmann.

    That said... I would pick the Oil Dealer! Better Customer service from oil dealer because they want you to buy oil. They have a vested interest in keeping your heater operating!

    Have you looked into the Energy Kinetics System 2000? I just had one installed a couple weeks ago and love it. It's super quiet and very efficient. The company has great customer service too. Its president and techs even frequent this forum. Check it out at the link below and if you have any questions I'd be happy to try and answer them. It would definitely be worth giving them a call to find a couple installers in your area and get an estimate or two.

    I would suggest zone valves and a delta p circulator. It’s rare to need 3 circs on that size system. A quality zone valve in good fluid quality will last 20 years or more and cost less to operate
