Thanks to everyone for the suggestions and advice regarding the hot water heat.
If I remember correctly, the water evidenced in the photo is due to some minor work I was doing to replace a rubber hose with clamps to a Sharkbite connector. I'll admit, however, that the maze of pipes is very complicated and confusing.

We've only owned this place since August 2007 and recognize we may have to live with some of these things until we can have on-sight experts make recommendations.
If there exists a hazard, I will ask someone to address it ASAP. Please explain the potential hazard referenced in the earlier post.
One of my other posts in a different Terry Forum asks:
I have a lot of plumbing work to do in our cottage, and it's likely I won't begin until early Spring. So, until then I'm getting all of the info I can, I'm buying supplies, and I'll keep being thankful for the advice.
This PEX stuff seems too good to be true regarding service life and its resitance to freezing, and it's likely I'll use it everywhere I can. One thing I did notice on another site, however, is that you cannot let it become exposed to sunlight or it will deteriorate. How about indirect lighting from a bulb? Can it be painted to keep it from falling apart?
Thanks for your help. To ensure the proper handling of my goal to avoid a freezing situation, I will consult a professional during my next visit there.
