salvaged pipe insulation
I picked up about 100 ft of pipe insulation (this was salvaged from old solar water heater installations) off Craigslist/free, thanks to my IFTTT alert. We have hot water baseboard radiators for heating and I plan on insulating all of the distribution piping for the radiators as well as the hot water pipes going to the shower, sinks, and appliances. All the pipes are in the crawlspace, which makes access to them very easy. I had to cut all of the insulation lengthwise (easiest with a scissors) in order to install it on existing pipes.
We already notice a difference the the shower hot water temperature and may be able to turn the water heater setpoint down a bit because of the pipe insulation.
