  1. These are very common GAS hot water systems, used in Australia for a long time now. Bosch, the German brand, is a common one. They do without a big standing tank, holding water, that is subject to the temperature changes around it, and not requiring to constantly heat a whole tank of water, so it is hot when on call. Instead, the gas wall system, has no pilot continuously running and is on demand. So as you turn on your hot water tap, it instantly fires up, and water is drawn through, a series of coils through the flames, basically. So heating as it is used. Much more efficient. However, gas in Australia, has done a massive turn around from being the cheap energy source, to the most expensive. Victoria now doesn't allow new builds, to have gas or new estates. So the system isn't really advantages anymore. This is despite Australia having possibly the biggest gas reserves in the world. It is basically all exported. A joke. Corporate politics at work. It's also what killed LPG vehicles in Australia - we lead the world in dedicated gas car systems: aka Ford Falcon E-gas Barra - which was better than the petrol version. Patented pre-priming system, where as you walked towards your car, your key fob in your pocket, would talk to the car, and have it ready to start, once you hopped in. Ironically gas is half the price of any petrol type at the moment and the cheapest. But not regularly available. Unbelievable. New hot water systems, are electric heat pumps - often solar powered.
