A customer using an oil-fired central heating system, whether a home or a business, can save £100s off bills with a HeatingSave energy management system. Via the HeatingSave controller you can change a room temperature requirement over 1,000 times a day, giving you 100 per cent control of the heating throughout the year. This has the advantage over traditional time clocks which set the heating to come on at a particular time and cannot vary the times throughout the week, wasting fuel at weekends. This accurate method of matching heating to building usage is particularly useful for businesses, saving money between 10% and 30%-plus.
