It is estimated that at least 40% of your domestic electricity bill is for electric water heating. So why choose Gas and not Solar or Heat pumps?Well simply put, Solar and Heat pumps require that the weather plays along. If it is cold or over cast then these products don't work well.
A Solar geyser requires the sun to heat up the water. During a sunny day this is fine, but on overcast days it wont heat up the water. If you use a lot of hot water at night there will be less or no hot water in the morning unless you have a backup of some sort, either electric or gas.
A Heat Pump uses the outside temperature to heat the water up in a tank. If the outside temperature is very low, the unit won't heat up the water to the required temperature. Another factor that must be taken into consideration, is how long a Heat Pump takes to heat up a tank of 200lt. The longer it takes the more electricity you use and the more frustrated you get waiting for hot water.
Gas does have a running cost that is linked to the oil price. The price of Gas is how ever regulated, this is the only negative aspect of using gas. In saying so, the running cost is still much lower than an electric geyser. The positive aspect is that as long as you have Gas, you have all the hot water you need, day or night, hot or cold weather. The initial installation cost is also lower than that of Solar or Heat Pumps.
The ultimate solution would be a Solar system with a Gas backup, the only problem is the initial cost outlay.
Why a Gas Geyser?
With the rising costs of
electricity and conventional methods of heating, a gas geyser can save you money
month on month. With a gas water heater, you are not paying for your geyser to
be kept hot all the time, as this gas geyser system works with a pulse igniter
that ignites the instant you open your hot water tap. Similarly the second you
close the hot water tap your gas water heater stops. This is the most efficient
method of hot water systems.
