<p>We can all cut our heating bill by 7% for every 1 degree centrigrade we reduce our thermostat setting by. We can put on a jumper rather than turning it back up and remain comfortable.</p> <p>So we're pledging to turn our heating down for a month and to give the money saved to the Hill School's fund-raising for a school in Africa to get solar power to improve health and education. Please join us and do the same. All you need to do is donate your saving here.</p> <p><strong>To calculate how much you would save:</strong></p> <p>heating cost saving per month = ((fuel bill) / (number of months bill applies for)) x (number of degrees temperature reduction) x 7/100</p> <p>example monthly gas bill saving calculation:</p> <p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; saving/month = (&pound;45 / 1) x 2 x 7/100 = &pound;6.30</p> <p>This calculation takes into account some of the fuel bill going on water heating and cooking.&nbsp;If your bill is entirely for heating then the fraction to multiply the cost by is 10/100 rather than 7/100.</p> <p>If this is too much hassle, just make up a number!</p> <p><strong>Donating your saving</strong></p> <p>Thanks for taking the time to visit our JustGiving page.</p> <p>Donating through JustGiving is simple, fast and totally secure.
