So everyhing about testing the heater this week went wrong!
It supposedly arrived Thursday evening, I got notification the courior had tried to deliver at 19.10. I use a friends language classroom which is open 9 to 9 bar the Siesta 2 to 4. Apparently he did not see any lights on, or the teacher, or the 6 students, and even managed to miss the 1/2 metre long notice board pointing out that in the unlikely event the class was closed he could deliver the parcel to the shop opposite, which is open 24 hours!
Nope he missed it all, nothing to do with finishing off early to get the carnival so not bothering with finishing his deliveries, I mean, carnival only lasts three weeks!
OK rant off, it arrived yesterday and was collected today. As is often the case with parts from breakers it was a bit rough, the usual grease and crud, rust on the heater elements, calcified deposits around the connections ect. So I popped in the hardware store and picked up abottle of 'aqua furte' or strong water, it is an acid used for cleaning drains, brickwork and of course grease and calcium, and does not bother plastics or metals, when I got home I started to clean the heater up.
It was coming up a treat, really nice almost like new. The inside had a bit of crud, so what the hell I dropped the whole caboodle in the solution and went in for a cuppa, I wandered back outside about ten minutes later to see a serious amount of smoke coming out of the bowl, the water frothing away, this along with sickening fumes gave me just a little hint that something was not quite right.
I grabbed a pair of pliers and lifted out the smouldering metal, my once nice shiny heater had started to dissolve and now had the nastiest metal rash you have ever seen, magnesium alloy methinks, ah well make that 'does not bother MOST metals'!
The heater body looking a little thin and porous in places however, as this is not for use in my engine I was not too concerned if it leaked a little. So a bit behind with the test, so bear with me, waiting on parts for customers cars so a bit of spare time this week to do the test.
