Hi Malcolm,

Total Heating Total Control (THTC) is a two-rate system, but is slightly different from Economy 10. It’s only used by Scottish Hydro (SSE) in the north of Scotland.

From SSE:
“With THTC you get two meters. One is for off-peak energy you use and the other records all your normal usage like lights, kitchen appliances and sockets… The specific times for the off-peak rate depends on the weather forecast for your area, but you’ll get between 5 and 12 hours each day. THTC works by storing up heat in your storage heaters and hot water tank during the off-peak times.”

“Other electric heaters and heated appliances can also be used on the cheaper rate. The off peak rate is available 24 hours a day for panel heaters, focal point fires, bathroom heaters, towel rails, the hot water boost and even electric showers. You’ll need to get an electrician to make sure all those appliances are connected to your cheaper-rate meter if you’re not sure.”

Not sure if you’ll be able to switch to another supplier, or whether you’ll need to change the meter to a ‘real’ Economy 10 first. Take care with teh wiring setup in your house though, it sounds as if the meter is directly switching on and off your heating and hot water, so you’d need a compatible E10 ‘switching’ meter as well.

Let us know how you get on!
