Tankless water heaters have taken over the water heating industry by storm over the past few years. They work by heating the water only when it is required. This could have potentially huge savings for a household. This is because unused water is not left in heating tanks. In short, the system only activates when it is required.
How It Works
The system works through a trigger mechanism. When water starts flowing through the pipes, the tankless water heater immediately is switched and starts a heat exchange system. The heater is fitted with a tiny tank where the heat exchange takes place. This tank’s walls are usually made of copper, which is less prone to corrosion but also has a high heat conductivity.
There are a number of variations to this system. Sometimes, the system work may work from a central point of from several points of use. This will mean installing a heating system at each point where the water is used. The greatest advantage of such a system is that there is no limitation on water use. This means one does not have to wait for someone to take a bath if one needs to do dishes in the kitchen for instance.
Which is the Best?
In most other appliances, it is usually cheaper to operate a gas-powered unit that an electric powered one. However, in a tankless water heater, this does not apply. For one, it is more complex to install a gas-powered model. This means one will definitely need a qualified technician to do the installation. With a more complex installation process, this raises the chances that there might be complications. This would mean extra costs.
Another reason why an electric powered model is preferred is that it is more efficient.
When it comes to a tankless system, it costs less to heat a unit of water compared to using a gas-powered model. This could lead to huge savings over the long term. However, it is important to note that the price of electricity varies greatly from region to region.
When considering the cost of electricity, it is important to remember one thing. A huge percentage of electricity in the country is derived from nuclear power. This type of electricity tends to be very cheap. As a result, it is less prone to shocks in market fluctuations. However, the price of gas is out of the control of the authorities. That means that at times it may go down to the extremes. At times, this price may shoot up. This makes it hard to make a precise budget.
Over the course of the operation, it has been found that electric powered models require almost no maintenance. This is very important when operating any system. A breakdown in the middle of winter, for instance, could have disastrous consequences. Thus in for maintenance sake, it would seem that an electric powered model is the best option.
When considering what type of tankless water heater to use, it is important to put things into perspective. There is no better or worse option, it will all depend on one’s choice and the geographical location.
