Understanding Central Heating
Around 90% of homes now have gas central heating. Within our living memory central heating has gone from being seen as a luxury to being relatively commonplace. The move away from the traditional solid fuel heating of key rooms has led to increased expectations for a warmer home. The Housing Energy Fact File published by the Department for Energy and Climate Change, states that central heating has led to people heating more of their house and for longer. This increased energy usage offsets any improvements in efficiency.
Central heating systems are powered by a boiler, which delivers hot water to a network of radiators in the home. The temperature is controlled by a central thermostat. Despite being able to set a programme centrally and modify the temperature of the radiators locally, research* suggests that controls such as thermostats, valves and time clocks may not reduce energy consumption of central heating systems.
One of the reasons being that all rooms will operate on the same heating schedule. The BREDEM industry assumed, demand temperatures and durations are; living room heated to 21 degrees from 7am-9am and 4pm-11pm on weekdays and between 7am and 11pm at the weekend. With a central heating system this means that every room in your house would operate on this schedule. Why would I want the heating on in the bedroom for 16 hours during the weekend?
Not only can our EcoHeat radiators be individually programmed to suit the pattern of occupation in a particular room, but each unit has a thermostat. So instead of one central thermostat controlling the temperature, every unit can be responsive to changes in room temperature. For a worked example please look at our heating costs section.
