Possible future works
The owner is considering a boiler and heating controls upgrade as the next energy upgrade. Although the existing boiler is only 10 years old and rated at 70% seasonal efficiency, its replacement with a 90% efficient condensing gas boiler would more likely yield significant energy savings and a greater payback. For further information, see section on space heaters, controls, heating pipes and boilers [link to follow]. Two multi-fuel stoves are also under consideration to the ground floor rooms.
