Is geothermal a viable option? In Ohio/US it looks like the breakeven point is reached relatively quickly, and it can also be used for cooling if you need it.

Definitely - in the context of heat pumps. Norway has no geothermal heat that can be used directly (the way the do in Iceland).
The "problem" is that heat pumps for geothermal energy are high quality, durable ... and at least 4-5 times as large investment for the heat pump alone as for the air-to-air heatpumps. And then you must drill a well, usually around 500 ft deep. As long as you built your house on rock, it isn't too expensive, but if it is build on sand, you cannot just drill, you must brace the hole to keep it from collapsing, which raises the cost significantly.
If you make the investment, your heatpump will have the same efficiency year round. An air-to-air heat pump doesn't give you much energy "for free" when it is -20F (or -30C) outdoors, when you need the heating the most. As you point out: Summertime, you can use the well for cooling (the Icelanders cannot do that!), and that is another significant reason why people choose a ground heat variant, rather than air-to-air.
Under my house, I would have to drill at least 150 ft, maybe more, before reaching solid rock. But I will remodel my garden, raising the level of the lawn by almost 4 ft. So I scrape off the old top soil, lay out a zig-zagging cooling pipe of 1200 ft length, fill 4 ft of soil on top and put the topsoil back. This moving of soil would have been done in any case, so the extra cost is limited to the cooling pipe (and a little work).
Another option used by some people is to throw the cooling pipe out in the river, into the bay or into a lake. But then it should be anchored well, weighed down, and lay so deep that water won't freeze around it. And you should make very sure that no boat is throwing out their anchor where you locate it.

150 ft of sand? Wow. I have four to six inches of soil before I hit limestone bedrock, so making a ground loop would require expensive trenching in solid rock. When they installed the farm drainage tile in the 1930's, they used dynamite, and I'm told the barn was filled with dynamite for several months. They used dynamite to excavate a basement in the 1950's too.

Not sand, more like moraine gravel. Nevertheless, it would collapse without bracing.
After drilling the hole, they insert an inner pipe where water in pumped down to the bottom of the hole. The water flows up along the outside, being heated by the rock on the way up. The heat pump can cool down the fluid to, say, -12C (or 10F), if needed to pick up enough heat for your house (but to keep the efficiency, or COP, at maximum, the heat pump cools it down this much only if really needed - it is more efficient to increase the flow at a higher temperature, if there still is room for that).
I grew up in a mountain town myself, and when I moved out, I was shocked to see that people would ever take the risk of building a house diretcly on sand/gravel. In my boyhood, I always thought that houses were built on rock, period! (So when we read in that book about the man who build his house on sand ... We immediately saw the sillyness of it, noone would build their house on sand, would they?)

My wife and I keep a reserve of about $150K. We also have several other accounts we could tap into if we needed, IRAs, an annuity account, CDs that we'd lose money to taxes if we tapped into them, but they're there as a secondary reserve if we lost our jobs and everything seriously went to crud. This does not include our 401k/retirement accounts that we would not touch for anything except retirement.

Using credit is not a sign of being, as you say, "on the wrong side of the savings limit."
Many credit cards offer things like cash back or points or something. As long as you pay the balance in full, it would actually be foolish not to take advantage of that (in my case) 1.5% cash rebate on the fridge. There are good and bad uses of credit, like anything else.
That being said, it seems like you and I are close in our approach to finances. Don't buy a new car just to have a new car; have an actual need, not a want.
Here in the US, we have a phrase, "<expletive> you money". It means, having enough reserves so that, should your employer upset you, you can walk away, saying "<expletive> you".
It's pretty nice. Everyone should have the good fortune to get to that point.

As a rule of thumb: Three month "prudent reserve."
Ensure it is sufficient to get through three months if all income completely stopped.
The rest is invested.
The three months provides time to access investments if income doesn't resume in a timely manner.
Damn tough when you have children, but it protects them also.
Cheers,

There's a smart financial advisor on the radio here in my part of America who advise you keep 3 to 6 times your monthly expenses in liquid form (e.g., a savings account). That way you can use cash for those emergency car repairs or appliance purchases, or stay afloat if you lose your job until you can find another.
If you think 'goto' is evil, try writing an Assembly program without JMP.

By the time you reach retirement age, you should have accumulated enough savings for 20 years of whatever lifestyle you like. That's a couple million dollars for a developer in the united states.
Let that number sink in for just a minute. You can't save that much money in the last 5 years before you retire. You have to build it up and compound it over time.
A senior software developer can be out of work for six months waiting for a good opportunity, and that's if the economy is robust. If there's a recession on, you might have to wait several months before you can begin to find work. Since it's hard to ratchet down your spending rate overnight (like by selling your house to get rid of mortgage costs), having a cushion of around one year's take-home is appropriate.
And it depends upon how much disaster you want to prepare for. My wife was paralyzed in a fail. Now she needs to replace 15 years income plus 20 years retirement. Fortunately we were good savers.

A half a year of cash, at least. A year, preferably.
Learned that from my folks when they had 4 boys going to $ school. That cushion seemed reasonable. Still seems so, 50 years later.
You have your head screwed on straight. Yes, TV says otherwise, but consider the source.

Thanks to all for the suggestions.
Alas, I bought a new radiator for the car instead. 
Maybe next month.

No dirty stuff in the Lounge, if you don't mind...
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.
