Okay, well here's the update. I had a Buderus 142/45 installed last weekend. The job took a total of 56 man/hours, and everything went reasonably smooth.

The unit has an AFUE of 95%. It uses a modulating technology that adjusts the boiler temperature with respect to the outside temperature. The jhigher the outside temp the lower the boiler temp and vice versa.

So far it has been just perfect, we will see what happens when we start getting into the real winter season.

Good luck with your boiler, now is indeed the time to go more efficient.
Good to hear that you are satisfied with your Carrier. I'm retired from United Technologies. I'd like to hear if you are satisfied with your tankless water heater when you get that installed. When I lived in Norway, we had a Bosch tankless and it worked perfectly fine. My home is now 7 years old, so I expect I'll be needing a water heater within the next 3 years.

Jumping in late here...I live in NJ and am taking advantage of the NJ Clean Energy "Home Performance with ENERGY STAR" program.

http://www.njcleanenergy.com/residential/p...e-energy-star-r

We have a home built in the mid-60's. The gas-fired hot water boiler is original and need replacement. I came across the program while researching boilers and could not be happier.

If you can achieve a 25+% decrease in projected heat energy consumption through a combination of winterization/insulation and new hardware, you can get a rebate of 50% of the work and finance the residual balance with a 0% / 10 year loan. They also give a $1,000 credit on the winterization work.

We are having a new Weil McLain Ultra 105 boiler installed with an indirect fired hot water system (basically a zone off the boiler). All new pumps, valves, backflow preventer, expansion tank are included.

Additionally, we are installing additional loose- and dense- fill cellulose insulation in the attic. Air sealing the basement rim joists with spray foam. Air sealing all the high hats in the non conditioned space. Attic stair dome enclosure. As well as other misc. winterization work.

Round numbers we started at $17k for the work. After the $1k winterization credit and the 50% rebate of $8k, we'll be at $8k. Plus we are eligible for the $1,500 tax credit noted early from the Federal Government.

When everything is factored in, we wind up at about $6k for all the work, which will be funded at 0% for 10 years.

If you live in NJ, you should really look into this program.

funny you should bring this up, I just took delivery of two of these


The existing water to air exchanger just couldn't get the job done. Even under normal conditions, it was barely passable and on really cold days I had to use manual override to get the fan speed up just to maintain house temp.
my thinking is if I can improve delivery capacity I can roll back my thermostats during the day and night.
I figure around 240K BTU/hr should be able keep up.

(for some reason my wife has been talking about Tim the Toolman again.
ugh ugh ugh )

I have heard that, when I started looking, I heard some good things, but since then, I have heard some not so good things.
