Can someone tell me what is the most cost efficient way of using a combi boiler.

I own radiators in adjectives my rooms with thermostatic valve on all but two of them. I hold been switching the boiler on for 5 to 10 minutes to roast the house up and then putting it sour.

Would I be better leaving the boiler on adjectives the time, putting all the radiators bad except the two without valve and keep it a constant heat. I can't afford huge heating bills but also don't want to be cold adjectives of the time.

The house is relatively new and very well insulated.
