Yes propane instant heaters are big here too Fred, Rinnai, Bosch, Adtherm being the major suppliers but, the issue I have with these heaters, they continue to supply hot water as long as someone wants to turn on a tap! I had guests having half hour showers, mainly through the winter because the water was hot and pressure great. Guests can do that at home but, it just chews up a resourse I can't produce and have to buy. I can't make propane but I can make electricity.
And although 80 Litres is not instantaneous, with a 3.6Kw element it will heat the tank from 10c cold to 50c in about 15-18 minutes.
If I had to buy my power at what it costs here Fred, I would have to lift my listing amount by 30% and that would definitely effect my booking potential!
