It seems our gas-fired hot water heater has lost its heat. I will now do the manly thing - crawl into a very tight space and try to read the instructions and even follow them. No messing around.
But I can't figure out why they don't put automatic lighters on these things. Maybe they don't go out often enough to make it cost effective.

That's how you can tell. When something stops, the warranty just ran out.
