Gas, Electric, Oil or Solar Water Heater?
Often homeowners need to choose between water heaters based on fuel type and costs.
In order to make a wise dicision we need to look at several factors, such as:
1. Availability of fuel: gas, electric, oil or solar
2. Installation Cost
3. Annual Operational and Energy Cost
4. Efficiency
Here is the table where all of these costs are added over 13 years of life:
Water Heater Type ~~~~~~~~~~~~ Installed Cost~~~~~Total Cost
___________________________________________(Over 13 Years)
Demand gas (tankless)................. $1,600 .............$5,008
Condensing gas storage................. 2,000 ...............5,170
High-efficiency gas storage ............ 1,025 .............. 5,220
Conventional gas storage ................. 850 .............. 5,394
Electric heat pump water heater ....... 1,660 ............. 4,125
High-eff. electric storage ................. 820 ............. 6,528
Minimum eff. electric storage ............ 750 ............. 6,769
Solar with electric back-up .............. 4,800 ............. 7,072
Conventional oil-fired storage .......... 1,400 ........... 11,299
If you look at all of the gas water heaters you can see that they are the cheapest ones based on total cost including installation. Only electric heat pump water heater is cheaper that gas ones, but usually gas water heaters are more efficient and cheaper. It usually takes less time to heat the water using gas fuel than electricity.
Solar water heaters have the cheapest yearly energy costs but also - the highest installation costs.
Solar water heaters are usually installed where there is a lot of sun available and gas lines are far away.
Oil-fired water heaters are the most expensive ones and if possible, should be replaced with gas or electric water heater.

My roof is facing almost due south with absolutely no shading whatsoever. I would like a comparison of the price as well as the amount of hot water produced by both systems under average UK conditions. An early response will be highly gratifying. solar water heating
