Didn't realise WD40 did fish oil! Thought the whole point of this thread was to get a temporary supply of hot water, while decisions were made about boiler. Therefore an immersion, cable and plug seems eminently sensible compared with thousands for new boiler
Wd40 is made from fish oil, that's why it has that distinctive aroma. It's a wonderful water dispersal agent and metal cleaner/polish (brilliant for cleaning fingerprints from stainless cooker hoods after you've fitted them) but as a penetrating lube it's pretty rubbish compared to most other products.
