Moreover, a tank-less heater acquires less space in your house and enables you to conserve natural gas. If you are looking for a model which will last long, a tank-less model should be your choice. Lasting up to 5 – 10 years or longer, the heater gives you an unlimited supply of hot water. It couldn’t get any better, could it? However there is a lot that goes into deciding whether you would want to switch from your conventional heating system to the tank-less one.

When talking about standard heaters, these units make use of heat to keep the stored water warm round the clock. This means that more energy is being used than what is actually required. This phenomenon is called standby heat loss. A tank-less model eliminates this energy loss and uses it only when hot water is needed. This is why these heating systems are also known as on-demand heaters. When the heat loss is eliminated, the heater becomes efficient as it is obvious.

Tank-less units come in two varieties namely point of use and whole house heaters. Point-of-use heaters are compact and small in size and will fit into small spaces easily. The main reason why you would want to install them is that they can be placed close to the outlet as a result of which lag time is reduced and water loss is efficiently avoided. In other words, as your water consumption increases, your water heating bill will be controlled. Whole house heaters on the other hand are bigger in size and can have more than one outlets. For this reason, these are more expensive as compared to the point-of-use systems.

When looking for a tank-less system, you can choose from natural gas, electric or propane gas models. Point-of-use heaters are mostly electric while whole house heaters are propane or natural gas based. The biggest advantage you can derived out of a tank-less heating system is that they will never make you run out of hot water. Secondly, if you buy a smaller unit you can easily fit that into a closet or under a cabinet. Thirdly, you can cut down up to 20% from your heating bill with a tank-less model. Fourthly, there is no risk of having your home flooded due to a ruptured tank.

With a standard heating model, you may need to keep a close watch on the tank for it may begin to leak as the heater ages. This problem can be avoided in a tank-less system. If you want to keep your maintenance costs to a minimum, tank-less water heater is the best choice!
