That sounds like nonsense to me. I would be disinclined to leave it (anything bar the fridge & freezer) on at night. Do you even have a night-saver electricity meter? If not then you're not saving anything. I just use it as needed, it heats up quickly.Some people have advised me to just stick the timer on all the time on the basis that it's actually cheaper to maintain a tank at a certain temperature rather than heating a cold tank up every day.

Turn it off completely. It is the most expensive way to heat hot water. Use your oil or gas to heat hot water. You will have more hot water in 1/4 of the time.
Immersions have a 3kw element therefore it is the same as boiling water in the kettle. It costs the same.
They maybe efficient as in the heat transfer rate etc, but they would still be the dearest way to heat water when compared with gas/oil
Does anyone know how much it costs to heat the water through the immersion? I dont use mine as it takes nearly an hour to heat up.
As stated above, 3Kw/h on bath, meaning it'll use 3Kw per hour. 2Kw/h on sink. How much are you paying per Kw/h for your electricity? Usually around 16c.
OP, 3 hours is way to long to heat water on the immersion heater. How big is your cylinder?
Typically it should take 30 to 40 mins to heat an average cylinder to 65 degrees C.
Are you sure this will get you the night rate? From [broken link removed]I heat my tank for 1.5 hours 7.30am - 9am to get the night save rate.

The hours during which the day and night charges apply for non quarter-
hourly metered customers are controlled by time switches at the
customer’s premises. The day rate is applicable to kWh metered between
8.00 a.m. and 11.00 p.m. (GMT). As no alterations are made to time
switches at the beginning and end of summertime, the hours during the
summer time are one hour later (i.e. 9.00am to 12.00am). For quarter-
hourly metered customers day rates apply 8.00 am to 11.00pm summer
and winter.
Thanks, ROA.
To be honest, I've no idea how big the cylinder is. It looks pretty standard to me (i.e. similar in size to others I've seen - about 4 feet high and 2 feet in diameter).
It will in the summer (ie now), but not in the winter as Nightsaver ends at 8am during the winter (ie when the clocks change).Complainer said:Are you sure this will get you the night rate?
