I'd certainly consider an envelope style design if I were doing new construction in this area. I bet I could cut my heating bills to a third what they are, but that's still requires a low cost to get a decent payback.

I think there is. I really like this guy's approach to the problem. It probably wouldn't be cost-effective if you paid for the labor (or included DIY labor at a realistic rate), but it would be a fun project. He got good payback even in Montana, which is a challenging environment. This application heats domestic water, but it would be simple enough to add a small heat exchanger in the HVAC system to use for space heating. It's definitely not big enough to provide all the heat for a typical home.

Features I like: Lots of storage and easy to add more. Simple. "virtually 100% efficient" water/water heat exchanger. Cheap ($1000 in materials)
Things I'd do differently:
-- The drainback system has worked flawlessly for him, but I'd probably add a failsafe redundant system. One malfunctioning contact and a frigid night could ruin a lot of PEX or copper.
-- IIRC, he didn't explain how he handles the CU/AL dissimilar metal corrosion potential in the non-PEX version of the collector.
For space heating there are, of course, simpler approaches using just a collector and a fan, but the ability to use this year-round for DHW significantly speeds payback.

-15 now and heading to +40 on Sunday. Sounds like T-shirt weather will finally return.

Ruh roh...this is heading right in our direction, probably reaching our area later today.
Central New York Loop - NewsChannel 9 WSYR

When a lake effect snow band is this organized, it will be a doozy. A friend in Watertown reported 4 inches overnight. Pulaski NY got 2 feet of snow over the past few days. Look for Pulaski in the middle of the map near Lake Ontario's eastern shore.

No, I do not live in Pulaski and never will.

The sun is shining brightly here today. So nice to see that.

I didn't want to sidetrack this already very long on-going thread, so I started a new one here:

DIY Solar Energy Projects?

spoiler alert: is it worth it?

We've got about the same as Ronstar's weather, 16 below this morning and forecast upper 30s for the weekend. Can hardly wait for spring, the older I get the more I hate winter; cold isn't too bad but I really dislike the snow.

Curious. Although my memory of this is dimming, I recall hating the cold but loving the snow.

We got 3 inches of snow last night. Stayed cold and still have most of it. But, warning up this weekend to 55. And next week, sunny and mid 60's all week. Time to get the rust off the old golf clubs.

The problem here is that the snow stays around from November to early April (sometimes into May). It makes it difficult to do anything outside; too much ice to comfortably go for a long walk without ice grips on shoes. A lot of the back roads are minimum maintenance so are not plowed in winter. It's just generally a PITA.

There is hope after all. At the moment the temp on the back porch is 15 F, but the forecast for the week ahead is highs in the low 50s. Finally, I'll get to take the motorcycle out of the garage! Vrooom!
