The comfort and convenience of a seemingly endless supply of hot water are for many people with conventional systems, a sought after dream. However, arguably, tankless water heaters or “Demand-type” water heaters have been available in our lives for a significant number of decades. Various reports indicate that this water heating process, for users of 186 litres or less is capable of producing energy efficiency, 24% to 34% greater than the usual water tank heaters. This factor is just one reason contributing to more consumers installing tankless water heaters in their homes!

How the tankless system works

Simply put, a tankless heater provides a flow of hot water in comparison to traditional systems that store and heat water as and when needed. It’s achieved with gas or an electric source that heats the water before it flows into the hot water utility. In comparison to a tanked heated water system, the tankless application does not require the use of a pilot light as water is heated during the day. Furthermore, whilst conventional tanked heating will be depleted of hot water after about approximately 151-litres to 190-litres.

This is positively added to by consumers with a tankless system not needing to wait for a storage tank to refill and reheat to receive more hot water. Another benefit is that the majority of thermostats for usual heaters have a setting of 120 degrees, but for the tankless option, the temperature can be reduced with resultant cost savings.

One aspect associated with tankless water heating is that must be appreciated by users is that although the heated water supply can be seen as endless, it is not instantaneous! Similar to the usual tanked water heating system, the tank-less application also requires a time period for the water heating process and reaching the faucet. However, upon the water being heated, there is an endless supply of hot water. This facility makes the tankless facility ideal for large families and high hot water demand applications such as laundry, dishwashing, and laundry.

Tankless types

There are various tankless models for heating water available and include those defined as condensing and non-condensing. In the case of the condensing water heaters, they are generally regarded as being more efficient, as well as saving on space to the extent of about 60-percent compared to a usual tanked water heater. It is however, strongly recommended by suppliers that consumers consider the size and fuel type of a proposed tankless heated water system!

In the event of gas installations, it should be recognized as being important to be aware of the size of the available gas line before any installation. Some tankless water heaters work efficiently with a 1.25 cm gas line, which is more affordable than those requiring a 3.75 cm gas line.

Some tankless heated water benefits

Looking at the economic influences first; although in comparison to a standard water heating system, the tankless is more expensive, it is usually regarded by the majority of builders as being in the upgrading category! In addition, the resultant cost savings overall contributed to energy efficiency can be a significant investment motivator for consumers.

To be taken into account is the fact of a tank-less water heater offering reduced energy and operating costs which could to a significant degree, offset the higher purchase price. According to the USA Department of Energy, the life expectancy of a tank-less system is in excess of 20 years. This alone makes for some investment comparisons and potential added sales value to a property and especially the fact of an endless hot water supply that is efficient, effective and convenient!

Should you be in the process of building a new home you have the opportunity of choosing a heated water application that will best suit your particular needs. Therefore, it would be worth your while considering how tank-less water heating can serve you with the best efficiency and cost effectiveness! In this respect, your builder will be able to advise you regarding whether they offer a tank-less water heater as standard or an upgrade option. If this is possible, determine the type, warranty term and exactly what is covered?

As this decision can impact on your lifestyle, ascertain the effect a tank-less water heater will have on your water-and-energy-efficiency, overall!
