High Efficiency Gas or Not

How long will you live in the house? How long will you live, period?

My point being, every BTU that goes up the chimney is gone for good having done no benefit for you in the process. New house? Save the chimney and put that money into the heating system.

Key to all of this is an accurate heat loss regardless of which type you choose. Keep the boiler size "tight" to the heat loss. Do Not Oversize.

Size the emitters to use 140 degree water, not the conventional 180. Use panel radiators if you can. Better yet, radiant floors. If you cannot do the whole house in radiant floors, the bathrooms, mudrooms and kitchen are all good places to start or at least tube them up while you have things "open". Basement slab too.

Spend it once, save forever and with greater comfort.

All of these radiation methods will take full advantage of the cooler water temperatures that are the hallmark of high efficiency boilers.

Even if your radiation is sized for 180 degrees, you can still save by allowing reset of the supply water with the outdoor temperature. There are plenty of winter hours where you can condense, hence save.

I am not familiar with the Laars Mascot, but the Weil-McLain Ultra, Lochinvar Knight, Viessmann Vitodens, Buderus, Triangle-Tube Prestige and others are all good choices so long as they are service-supported by the installer. Each has a following here. This is a great age, plenty of choices.

Go forth with confidence. Do it Once, Do it Right, as Taco says.

High Efficiency Gas or not

I am building a new house, they want install a Larrs mini them non HF.
Is it worth the moeny for a HF and will it heat better?

What units are best need about 225000 btu for hydro air
Lochinvar Kight? Larrs Mascot? Welie Mclane Ultra?
