    Mod Cons

    Mod cons will usually work well with existing radiators. Hopefully you can find a contractor in your area that has expertise. I like the Viessmann Vitodens 200 and their VitoCell 300 SS indirect tanks. I use an NTI Trin n Stor, if the Vitocell is over the budget.

    When retrofitting a radiator system, we always change the radiator valves to TRV's. The system will perform at highest efficiency when a "Smart" pump (i.e. Grundfos Alpha) is installed on the heating circuit.

    Agreed

    The Triangle Tube, The Knight WHN and the Utica/Dunkirk at the bottom of the page are good mod/cons that we install and like. I would not use a boiler with a Gianonni heat exchanger unless you have a good servicer that's going to do thorough annual maintenance. Many manufacturers use this heat exchanger, so you need to ask your installer if the boiler they're proposing has it.



    The most important thing in the equation is the installer: he's 98% of it. Make sure you get references and pics of his recent installs and post what he's proposing back here for review if you want recommendations.
