Halogen heater question

Any form of electric heating will cost her 350% more per kWh than using the gas CH. The extra cost of about 24p per kWh will over a single winter at current electricity prices be vastly more than the cost of installing TRV's on the rads. They're about a tenner each.

@Rusty190 I saw the three part remote set that @grumbler suggested today at The Range today for £14.99 so problem solved :-)

Thanks @macman I'm not very good at kWhs thermal dynamics and British Thermal Units –  but I undertand it's an approximation of the amount of energy required to heat 1lb (one pound) of water from 39°F to 40°F, and is roughly equal to 1.055 KJoules. Simplified, a single BTU is more or less equal to the amount of heat and/or energy produced by burning a single wooden match from end-to-end. but I understand that 1kWh is also 3412.14 BTUs.

The thermostat would need moving also, its the install cost that hurts.

You really are over-complicating this. Forget BTU's, they are obsolete, but it doesn't matter if you measure energy in kWh or BTU's. Whichever way you measure it, BTU or kWh, electricity is 350% more expensive than mains gas per unit of energy. 
Since you are billed in kWh's, that's the relevant measure.
Your gas boiler is less efficient than any electric fire, but even if that efficiency loss were as high as 20%, then gas would still be a third of the price of electricity, after allowing for the lower efficiency.
