How easy is it to switch from a gas water heater to an electric water heater?
What are the pros/cons of each?
The most difficult part is running the electric power line to where it is needed, may actually be easy. All depends on your set up. Tanks are fairly easy to switch out and such.
easy you just need a electrician to install a new circuit
You will have to run a cable from the circuit breaker box to the location of the electric hot water heater. 240 volt, xx amp, Go to somebody's house and look at how it is wired. You can find the material at Lowes, but you will have to have the tools and skill. Of course, you can justify buying really good tools to do the job, if you do the job yourself The cost of hot water will go up compared to gas.
I needed a certified gas fitter to disconnect and cap my gas line and an electrician to run a new wire dedicated for the hot water heater. Electric hot water is okay I guess. When the tank needs replacing I can do the rewiring myself as everything is laid out. The dryer line was not touched.. It is a separate breaker.
The physical plumbing for the water would be identical.
The gas line would have to be capped, but anyone qualified to service the gas can do that in a few minutes.
The only thing that MAY be an issue is if you don't have a dedicated 240 volt circuit for the electric heater, but that can be added.
As for advantages, a gas heater usually costs less to operate, but an electric heater can't develop a gas leak.
Call a professional plumber/HVAC technician. Installation is NOT for beginners.
you have to run a new, dedicated 220v power circuit for the electric water heater. that requires space in the breaker box, new breaker of proper size, available amperage in the breaker box, running the proper size cable, installing a cut off [in a box] at the water heater [so future repairmen can be certain they have the power off -- and it's required by the building code]. And, probably, some plumbing work on the incoming cold water line, overflow line, and the outgoing hot water line.
you also have to safely cap the gas line.
Hi here in the united kingdom the gas water heater is a lot less expensive way to heat water than electricity.
Yes. Far easier than the other way about.
If you are doing anything more than a local sink point, you will need a dedicated 30 amp supply from your distribution board.
Bear in mind that gas is still about 40% less than electric. Showers tend to be cost effective because of the small amount of water used and the fact that it is heated at the point of use, but filling a bath is going to be more expensive. You should look at instantaneous systems - ones that store heated water lose are expensive options.
The advantage is that you could get some of your electric from renewable, albeit at higher capital cost.
Do you have electricity?
Do you have an outlet?
Once again, this is a question that indicates the need for professional work. "If you have to ask on Yahoo Answers, then your do-it-yourself work is almost certain to contain blunders." The result of water-heater blunders can be anything from annoying leaks to catastrophe. If your house is destroyed by a gas explosion or an electrical fire, regardless of whether it was caused by your (obviously do-it-yourself) water heater installation, then your homeowners insurance might not cover the damage. When I do work on my home I follow the recommended US National Electrical Code from the NFPA. My wiring is indistinguishable from the work of professional electricians. I avoid doing anything at all with gas.
Get detailed, written quotes from three licensed professionals, each of whom has proper understanding of gas, electricity and plumbing. If a plumber cannot give a written quote but instead waves his hands about and spouts numbers, go with someone else.
Bear in mind that electricity is significantly dearer than gas. You would need a dedicated circuit installed and there is the cost of a new appliance. Gas heating has improved in efficiency over the past years. So it may be wise to look at high efficiency gas water heaters.
