We all know immersion heaters are expensive to run compared to gas boilers, when it comes to heating your hot water. But is that always the case?

Part 2: https://youtu.be/ZmyaoFwcleg

In this video I calculate the running costs for our own hot water use for both the gas boiler and the immersion heater to see what the real answer is for our particular situation.

I encourage you to work out your own daily energy use for both gas and electricity and perform your own calculations using your specific energy tariffs.

We use about 7 kWh of gas each day for hot water but using the immersion heater it is closer to 5 kWh (see the earlier video in this playlist). In this video I assume we would use 6 kWh of gas per day if I was able to continue making our gas system more efficient. I think 6 kWh is a reasonable target but if you disagree with any of these numbers you are welcome to perform your own calculations using the daily values you think are reasonable. In fact I insist you do your own calculations!

Also, please be aware that time-of-day tariffs will have higher daytime rates than regular tariffs so you will need to calculate the cost of your daytime electricity use for both tariffs in order to get the full picture. Apologies that I didn't do that in this video, I will try to record a follow-up video covering that calculation soon.
