Best electric heating options

if the window is south/east facing and get the sun you might find a lot of days it is going to warm up anyway in the morning.

As per Molerat, especially if you have gas fired central heating!
Adding the pipework and another zone could be in the same order of cost as installing a new supply for storage radiators (situation dependant!). Running costs will be lowest.


If you already have electric power in the garage cheapest capital outlay is tubular heaters (timer or manual control) or oil filled radiators (with timers to start heating prior to office use as slower to warm up) or fan heater. Running costs highest per energy used. Electricity can be 4 to five times the cost to buy units but is 100% efficient converting units to heat and is great for control so losses can be minimal. Gas CH is less efficient at conversion (from about 50% on an old poor system to 80%+ with best new systems) but still wins hands down on running costs.


Will you not want some heat even when the office is unused? (keep it dry, prevent condensation , frost etc.)

No (modern) E7 is just TOU. Older meters did send a signal to strorage heaters (etc) to tell them to start. but they don't like to do that these days.

The signal will come from the radio teleswitch or meter to pull in a contactor which will energise an off-peak distribution board.

Why isn't your electrician dealing with this? Should be an integrated approach: heating/ ventilation/ insulation/ energy saving, all to current Building Regs for a room conversion.
