New cooker - full electric or dual fuel

PennineAcute

Forgetting efficiency, irrelevant of fuel type, it takes the same amount of energy to heat something to a set temperature.

My currently  renewed electricity (22.38p) is around 4 times more expensive than my currently renewed gas (5.48p).

Therefore, if an electrical appliance is  over 4 times more efficient than a gas applicance at heating something, then it would be cheaper than using gas.  When I swapped from an electric to gas cooker, back in 2018, I noticed a massive decrease in my electricity usage and only a little dent in my gas usage.

Forgetting efficiency?? It is quite relevant.

Which would be cheaper, an electric appliance delivering 100% of the energy used to the device being heated, or a gas appliance delivering only 10% of the energy used?

Or what about an electric hob that takes 20 minutes to heat up...

The above hob, popular in rentals, but grossly inefficient as well as being nasty to look at. A gas hob would be much more efficient, but I'd still replace with induction (indeed, went and got my niece one to replace that nasty thing).

Firstly, as an adult maths, English and Lifeskills tutor, you would be amazed at the number of people who think, as an electric kettle boils faster than a pan on a gas cooker (containing the same amount of water), that an electric kettle is cheaper than boiling water on a gas stove.  Hence me starting off with "forgetting efficiency, ..."

Using the figures that I gave, if boiling water on an induction hob is over 4 times as efficient than boiingl water on a gas stove, then it would be cheaper to use this method.  You can talk about if is cheaper to do this, or to do that.  Unless you have the figures to do the calculation, it is all just talk.

A few years ago, after replacing my electric cooker with gas, I did the test.  Turned off all power except to the cooker socket and used my In Home Display Unit to measure how much it cost to use the kettle.  I then did the same with the gas and worked out I was saving around 1.5p per boil using my gas cooker to boil water.  10+ boils a day turns into a nice saving.

So, I stand by what I typed earlier.  If you want to deliberately misread what I typed, that is your choice.
