Tips on energy saving Tips on energy saving Heating economically The appliance provides a high level of comfort whilst keeping fuel consumption and the environment effects as low as possible. The appliance is controlled in such a way that it delivers heat at the correct rate and only if there is a clear demand from the system. Central heating systems with room thermostat/thermostatic radiator valves With modern heating systems set around a 20 °C heat loss, the optimum setting for a condensing appliance will be approximately 73 °C for the central heating temperature.
The householder may be asked to prove the date of installation, that the appliance was correctly commissioned and, where appropriate, the first year's service has been carried out to the satisfaction of Bosch Thermotechnology Ltd., when requested. These should be documented as a part of the Commissioning Checklist.
Glossary Glossary Central heating systems All radiators must be heated at an even rate. If the top of a radiator is at a lower temperature than the bottom then it should be bled by releasing air through the bleed screw at the top of the radiator. Ask your installer to show you how this is done.
