If you are going to switch from a standard hot water heater because your current system is not providing what you need, then it may be time to look into a tankless water heater. It is far more green then a conventional tank and the cost savings can be significant when compared to the use of either a gas or electric unit.
But it is important to note right up front that the cost of converting your current system to tankless or "demand" is more costly then substituting a conventional tank. First of all, the tankless unit is more costly. Whereas your normal tank for replacement can be had anywhere from 0 to over 00, plus installation costs of 0 to 0, an instant model will run from about 0 - 00 with additional costs for installation, particularly if the supply lines and venting options for gas are not adequate. Gas units are often a little higher costs for installation because of the venting required. Installation costs for on demand hot water systems typically run 0 to 0.

On Demand Energy Savings
The higher the cost of the individual unit, generally, the more cost effective to operate in the long run. So if you need to spend a few extra hundred for a more energy efficient model, figure out the cost savings over the life of the unit rather than just the upfront costs.
Gas vs Electric Tankless
Gas or electric demand units average about the same cost to purchase. The gas, however, is more expensive to install due in part to the necessity of venting the gas fumes. Modern units are generally placed outside, so as to avoid the necessity of venting through the roof or through a wall. The other costs involved with an outside mounted unit is that in some instances where the unit is far away from the outlet, i.e. kitchen or bathroom, a circulation pump may be added to have instant hot water at the most remote location. It is not always necessary, but in certain instances a simple fix when compared to adding a second demand unit. Electric units often require a 240 volt electric for the most efficiency.
Lasting Hot Water
The on demand systems often last 20 years or more, with very little maintenance. As the cost of energy rises the savings increases proportionately which means an even bigger savings in the long run. Gas has been cheaper to operate then electricity, but that may not always be the case with the new technologies that may added in the future.
Tax Savings
Since everyone is trying to reduce our dependence on oil to operate our lives, the Government encourages energy fixes including those connected with heating hot water. Switching to an energy efficient tankless system provides up to 00 in tax incentives. Some States also include tax incentives or direct rebates for installing more energy efficient systems.
Bottom Line
If you are switching to a gas on demand system for a family of 4 in a house with 2 bathrooms, the cost will be in the neighborhood of 00 - 00. For an electric system, the cost will be between 00 - 00. Purchasing the units directly and having a qualified technician (licensed plumber) to install will be the most efficient way to reduce the cost involved.
