A converted gravity system and tube-in-slab radiant addition nearly scream "condensing/modulating"!

I agree...

...unless the owners plan to move soon and hence do not expect to see any of the benefit that a condensing boiler brings to the home. According to Gordon's personal experience, super-efficient homes do not sell at a premium. Maybe todays energy prices will shift that thinking...

So, if these owners want to stay there for a while, I'd look into how to make the whole thing possible for them, perhaps going as far as a construction loan or whatnot. The payments ought to be less than the savings, so the client has a net gain.

At the end of the day, it's their decision. If they want to stick with a cheap boiler, there is no point in banging your head on the wall too hard about it. All you can do is lay out the options, give them the choice, and then do the best you can with what's been given to you.

Hitting the price point...

Kevin,

Some folks have suggested (and used) the newer Crown
"Cabo" and the Slant Fin "VSPH", with good results.

If the fuel were to remain oil

Vitola 200 boiler, Vitotronic 200/300 control, 3 or 4 way mixing for the radiant slab, boiler water to the cast iron, indirect DHW.

As the fuel is NG, same configuration.

No need for me to apologize here for waving the flag. I just installed this in my own.

i know, i know....

I want to give them choices...good, better, best. Outdoor reset is a must. But can they afford the Ford Taurus or the Lexus?

Condensing a must

Depending on the heat load you might look at the Prestige, by Triangle Tube. Munchkin is also very reasonably priced. You talk like it's a high dollar item. You should price them some German condensing boilers first and they would be relieved at the Munchkin-Prestige price. WW

You could save them even more money

with a Polaris fully condensing stainless steel DHW heater.
