Peter I know I'm full of it - but no - I don't have one. LOL
I have a solar water heater that has it's own 40 gallon tank. At the apartment in town I had one of those things that fit onto the shower head and almost electrocuted myself a number of times - they tend to short out. In the states I had a true tankless system but it ran on natural gas and was sparked by electricity. I think I saw one advertised someplace here in Belize. I would talk to Mr. Castillo - he would know.
