On demand electric heaters are not very practical. It depends on your electric rate, if you do not have a demand charge and rates are low due to large hydroelectric usage then they may be practical. Also gas prices may follow oil prices and the NG heaters may end up costing more in the near future.

i looked at on demand and it appears from statistics they cut bills by about 2/3rd. i talked with a few plumbers who say they are a headache.. because people do not know how to operate them and complain of cold water. you need to open the hot water faucets for a flow large enough to keep the system running vs some people shutting back the flow once they get hot water vs mixing the water with cold water flow. if you cut back the rate of flow on these on demand heaters they shut off. if you do not use a lot of hot water , retired couples etc i can see a big benefit vs heating a 40 gallon tank continuously. in the end i replaced the hot water propane tank with another one vs take on an unkown.. i did have on demand tank , fuel oil, in 1972 , the shower never got hot enough for me but we always had hot water for washing etc. the tank and furance were stored in garage and in winter in r.i. you are fighting some cold temps in the garage to start.
