More information has been added by Practical Home Energy Saving to the page on toilet cisterns in the water saving section. Somewhere around 30% of domestic water usage occurs from flushing the toilet so this is obviously an area to give careful consideration to. Modern toilets use a dual flush mechanism using between 4 to 6 litres of water. People flush the toilet around five times a day each on average. Unfortunately most of us are blessed with cistern capacities of 10 litres or in the case of really old units 13 litres. The obvious course of action is to replace the cistern mechanism and possibly the cistern but this costs money. There are however several thing that can be done for free to save water: One obvious way to save water is to educate people to use the correct part of the dual flush mechanism when one is fitted.
More ideas have been added to the miscellaneous heat saving page by Practical Home Energy Saving. A lot of the information on this page is aimed at reducing draughts and it is vital that rooms remain properly ventilated, especially when they contain boilers and fires. If in doubt get professional advice. One major source of draughts can be gaps around any cables or pipes coming into a room through the walls, ceiling or floor, these gaps are usually very simple to seal – where possible seal the gap on both sides. Often there are gaps around light fittings which need sealing – be careful here and get advice if you are unsure about dealing with electrical fittings. Sometimes there are cracks in ceilings and walls which go all the way through and these need sealing to stop draughts.
Following more great suggestions from readers Practical Home Energy Saving has updated the radiator faults page. If the rooms are reaching the desired temperature and the thermostatic valves are cutting off the flow it is likely that all the radiators will be at different temperatures. It all depends on how hard the radiator is working to maintain the temperature. The hotter the temperature the less the thermostatic valve is closing. How hard a radiator works depends on the size of room being heated, the size of the radiator, how high the thermostatic valve is set, how well insulated the room is and how often any external doors are opened and closed.
