High Efficiency Water Heater

Some Questions on High Efficiency Water Systems People have many questions when it comes to the subject of high efficiency water heaters. This is because this is still a fairly new way of heating water and can create confusion as there is a lot of misinformation on the subject.

If I buy a high efficiency water heater, will I be able to save money on my bills?

Yes, in a normal family house, a cost saving of between 10% – 15% is possible. If you purchase a really good high efficiency water heater, you will find that it will use only half of the energy needed to heat water compared to a normal water heater.

How come there is such a difference?

When it comes to high efficiency water heaters, there are many factors to take into consideration. In a larger house, the water tank may be installed in a position which is some distance from any one of the hat water taps. If the hot water needs to flow though many pipes from the tank to the tap, it will be cooler by the time it comes out of the tap. So that is a loss in energy right there.

Is it only tankless systems that can be considered high efficiency?

No. It is possible to have a high efficiency water tank which could still use up to 20% less energy than a standard water heater. These are usually fuelled using propane, natural gas, electric or oil. There are also high efficiency water heaters which are powered by solar which can cut the cost of bills even further.

While the cost savings are all to plain to see, the biggest problem with these new types of system for many people is the cost of the purchase and installation.

Are high efficiency water heaters worth the extra initial expense?

Without a doubt. Yes, they can cost a little more to buy and install but they usually pay for themselves very quickly as the cost is offset with the savings in lower fuel bills.

However, for those who do not have a big family and do not use much hot water for showers, washing dishes and other normal chores, then the difference in savings may be very minimal.
