best gas boiler on the market

BA

Replacing oil boiler with a gas boiler, for a 3800 SF house. House is all stone with adequate insulation. Would like some feed back on Quality gas boilers. Thanks BA

Questions

Steam or hot water? One pipe or two pipe (both steam and hot water can be either).

What type of emitters? e.g. iron radiators, baseboard (aluminum or cast iron), radiant floors, etc.? Are the emitters all orginal or at least all of the same general form?

Which came first--insulation or emitters? Is the insulation on the inside or outside of the walls? (I know that sounds like an odd question, but in Europe it's quite common to put insulation on the outside of solid masonary buildings.)

Is the system current zoned? If not, do you have any need to zone the system?

BA

Mike, It is hot water basedboard aluminum fin. Insulation is on the inside of house. One loop system, but, I just zoned if off with two heating zones and one for primary domestic hot water. I also added a indirect hotwater tank due to lack of hot water. I would like to add a tekmar control for the new gas boiler to save when the temp not too cold outside. Sorry for not being specific enough. BA

The Triangle Tube Prestige is the best overall value in a stainless steel condensing boiler in my opinion. No additional Tekmar controls are necessary.

Given what little I know, and provided it is installed properly my suggestion is a Vitodens 100 with Tekmar TN4. I believe this combination will give you a nearly unbeatable combination of quality, comfort, longevity and value for the dollar.

You could certainly achieve higher efficiency, but given what I understand of the nature of your home and system such would require significant and expensive changes with little chance of "payback".
