The best method to guarantee your heating system is operating at peak efficiency is to have it serviced or tuned up annually. A simple and cheap strategy to reduce your heating expenditure is to keep the system clean and to change the filters regularly. The installation of a new, high-efficiency heating system should be considered if the current one is more than ten years old or requires regular maintenance. You may have to spend more money on a high-efficiency furnace initially, but you'll save money every month.
This smoky odour is due to the dust your furnace burns off when it returns to operating temperature. There is no cause for alarm, as this is perfectly typical. After the stove has burned all the dust away, the odour should disappear.
When comparing unit costs, gas heating (10p/kWh) is more affordable than electric (34p/kWh). On the other hand, the average cost to install an electric heating system is only around £3,790, while the cost to install a gas central heating system is over £5,250.
It is recommended that you have your furnace serviced once a year by a professional. Some people put off maintenance until it's too late leading to furnace failures and expensive repairs.
