Hello, we bought a new house a year ago and it is using about £80 of gas per week at the moment - around 150 units per week for a 4 bedroom house with 2 bathrooms. We run heat for 2 hours in the morning at 20 degrees and 6 hours at night and heat water for around 5 hours morning and evening combined. Combi has a megaflow attached and house has 2 heating zones but even if I only switch one zone on the usage is astronomical. I am living in a cold house too afraid to turn on both heating zones due to cost. We are very alarmed at the cost but don't know what to do as visiting heating engineers just quotes to install a new system for £6000 plus. Our metre has been checked and it is not faulty. Are there any possible reasons for this usage which we could fix rather than have to install a whole new system?
Any help greatly appreciated. Thank you.
