Dux in Australia already has a tankless continuous flow water heater with a heat exchanger as well. http://www.dux.com.au/products/4 Not sure what Gavin Oven is going on about with his enthusiasm about WDRP's tankless heater. They are already for sale by a large public company in Australia. It will be very difficult for WDRP to break into that market. jmo
You are right. Tankless water heater is not new. If Wanderport is another tankless water heater, most longs would not be interested in the stock. It is not another tankless water heater. It is a microwave tankless water heater, which is not the same as gas type or electric type available in the market. Read my other post that explains a little bit more in length.
