However, it would be in your best interest to look around your area first to find which one is more suitable for you as this of course in not a cheap investment. If you want to go for gas, it is important that you have a gas line that pipes into your property. If there are no gas lines in your area, then it is best to settle of electric units as they too can provide you with considerable amount of savings. It is also highly suggested that you try to purchase units with brand names as this will provide you with both quality and durability.
When using on-demand water heaters, it is important to keep in mind that the more immediate volume of water you require from the unit, the longer it will take to heat up the water.

In order to get better results, it is suggested to install the heating unit as close to the tap as possible. This will give the heat lesser distance to dissipate.
