The pipes in our bathroom are behind a tiled wall, the space they occupy is an overhang and basically a tiny loft crawl space (it's a dormber style house). There is only partial lagging on the cold pipe as far as I can make out.
We've never had an issue all the time we've had the house (15 years) but, with the recent cold weather, I decided to put a thermometer probe in there (through a hole one of the pipes comes in through) to monitor the temperature. Lowest I've seen is just over 5 degrees.
Now, we've never had an issue but, simply knowing how cold it does get in there, it's now playing on my mind and I find myself constantly checking in case it gets any colder - I'm worried pipes could potentially freeze etc.
My options are limited without tearing down the tiled wall. I've seen pipe trace heating but there is only a couple of inches of the two pipes exposed - are there any clamp on pipe heaters available that would warm the pipes - similar to the pipe freezes but working the other way?
I can get very limited access by taking the bath panel off but since I'm not 6 inches wide, I'm unable to get anything other than an arm into the space and then only from that one side. Was contemplating rigging up a light and webcam to get a view into the space and then somehow filling the area up with loft insulation over the pipes etc. - blowing it in, pushing it in with some sort of flexible pole etc. etc.
Alternatively, my last real hope I suppose is to get a roofy in and get at the space from the outside by removing the tiles and felt.
Any other ideas? E.g. trained rats to pull the stuff in, tiny little plumber able to fit in there etc.?
