Hi Sniggings,

I don't think I can work out the costs as I only bought the place recently...Do you have any suggestions as to how I can estimate without historical readings?

Thanks!

Will only be a rough guess but should be enough for you to know if it's worth changing now.

Work out what you will be using electric for between the cheap rate hours, most/all electric equipment has wattage on, so a 100w light for an hour would be 100-1000=0.1kwh which is 0.1xyour unit rate, which is likely around 8p on cheap rate, so 0.1x8p=0.8p an hour, do this for everything you are likely to use, alarm clock,maye washer? lets face it, probably not much electric use over night.

As you can see from the light example, you would have to use a lot of night time electric to justify the day tariff. of 17p 18p? , when you could have an single tariff of around 14p

or

just take a reading at the start of the cheap rate hours and again at the end, say for a week, your usage will likely be the same over a week, this will tell you how many units of electric you use over the week,then times that by your cheap unit rate electric tariff.

All,

Many thanks for your help on all of this stuff. Very much appreciated!

I however now have another problem. My Ariston WRC-NSF tank is not heating water properly (the overflow leak issue was sorted out by Homeserve, and turned out to be the T&P valve).

When I switch the top immersion heater on, I get hot water as expected. When I however switch the bottom immersion heater on (off-peak, main usage heater), the water is only mildly warm.

As I still haven't moved in (but hopefully next weekend ), I'm not quite sure whether the bottom immersion heater was heating water to the correct temperature or not.

Having had a look online, I see that there is a reset buttom on each of the thermostats for the heaters, as well as a screw to adjust the temperature.

I'm thinking to have a go at adjusting the thermostat, but what is the best way to find out what temperature it is heating the water to?

Many thanks in advance!
