i normaly use our gas boiler to heat the water tank . im thinking it might be cheaper to use the emersion heater as the boiler and pipes have to heat up with the gas every time its calling for heat .the tanks lagged and immersion heater in it with thermostat .. anyone any thoughts on it

Just go off your pence per Kw, electric = 30p, gas = 8p (roughly) . Decent gas boiler is about 90% efficient, minus some pipe loss, I think it would still be cheaper to use gas rather than electric.i normaly use our gas boiler to heat the water tank . im thinking it might be cheaper to use the emersion heater as the boiler and pipes have to heat up with the gas every time its calling for heat .the tanks lagged and immersion heater in it with thermostat .. anyone any thoughts on it

Have you taken readings recently? Seems really low and electricity company estimates can be way out.

I've got some jump leads in the car......And they can't be remotely shut off on someone's whim...
I remember when I lived in Thailand it was a common trick to wire a 'shunt' across the meter, which I assume is a resistor, to allow a certain amount of current to bypass the meter. It was very common, but I never owned my own place so didn't get involved. Guys would come knock on the doors of houses offering to install said device.

I had the same thought, and checked it out, gas was still multiple time cheaper.i normaly use our gas boiler to heat the water tank . im thinking it might be cheaper to use the emersion heater as the boiler and pipes have to heat up with the gas every time its calling for heat .the tanks lagged and immersion heater in it with thermostat .. anyone any thoughts on it

It's proven tech, gas is cheaper per unit of heat, no matter how much drivel the hopeful electric guys spew forth.

I change to immersion during summer months...or did. The immersion's packed up and don't fancy being fried and covered in fibre glass to investigate loft.i normaly use our gas boiler to heat the water tank . im thinking it might be cheaper to use the emersion heater as the boiler and pipes have to heat up with the gas every time its calling for heat .the tanks lagged and immersion heater in it with thermostat .. anyone any thoughts on it

Because of the problem of heating a loft immersion tank and using 5 lt of water before it ran hot , I had an under sink heater fitted just over a year ago. Best thing I ever did. I even asked my plumber about putting one in the bathroom, just for the sink, but he came up with the alternative of t piecing the current unit it the bathroom at a quarter the price. Works perfect. There are valves on all feeds so only a minutes work to switch back to the loft tank. Far more economical to heat 15 ltr to wash hands or dishes now.

I switch to immersion heater during the summer too, heat it on off-peak overnight and the tank normally lasts the day

I've often thought about one of them, as my gas fired combi boiler is out the back end of the garage, so a 30' run of pipe before the hot water gets to the kitchen sink. It will almost fill a washing up bowl with cold before the hot stuff gets to the tap, so I currently wash up in cold water, or boil a kettle for something greasyBecause of the problem of heating a loft immersion tank and using 5 lt of water before it ran hot , I had an under sink heater fitted just over a year ago.

I suffer from the same problem, water is heated by immersion heater but pipe run means it is well over 2 bowls before I get warm water. However I wonder if going to one of those "electric geysers" and leaving the hot tank and pipes to go cold, would lead to corrosion in both, as I heard that it is the heat that stops oxygen in the water from doing damage. Anyone know if this is true.

Be interesting to find that out, as my boiler hasn't run in 3 months or more, not for heating or hot water.
Should all such systems be fired up occasionally to prevent damp/rust/corrosion etc?

Quite honestly I would be more than happy to remove the loft tank, pipes and wiring as they will never be used again, but will leave as is unless there is a problem. Had the bath removed and a shower unit installed so no need for 20 gallons of hot water.
