Just back from Tewkesbury Aldi.
Loads of thermometers (-3 for me), splitters and moisture meters in store.
I was eyeing the ash vacuum bin as I dont like my current one, but the one in Aldi is not sufficiently different to make me think that it wouldnt suffer from the same problem – overly stiff hose and crap hose connector to the bin – so didnt pick one up.
Have just realised (doh) that the magnetic thermometer wont fix to any of my stainless steel flue ( 🙄 ) but I can fit it on some other parts so should be OK. wont be testing it just yet at least until this indian summer weather breaks!
