Hi,
I live in a 2 bed apartment which has GFCH. There is no immersion, so the gas boiler is used to heat the radiators and the water. I'm trying to work out the most economical way of using the heating while obviously remaining warm and cosy! The apartment is quite small (750 square feet) and when the heating goes on, it heats up fairly quickly and it retains the heat for about an hour. I share with another girl and we have the timer set to come on for 15 mins at 6:30 when we both get in from work, then 15 mins at 7:30 and then another 15 mins at 8:30.
I would have thought it would be more economical to have the heating on constantly on a low heat for two hours than have it go on and off three times for a short period of 15 minutes. This was confirmed by someone in Bord Gais however we don't know whether to believe them as it's in their interest that we spend more!
Advice appreciated!
Thanks
