What does sustainability look like in daily life? I thought I would share our (me and my husband) experiences.
About ten years ago we installed double glazing, put solar panels on the roof, installed cavity wall insulation and fitted two wood burning stoves in an effort to reduce our carbon footprint. The cavity wall insulation and the double glazing produced an instant effect with the house feeling much warmer. The stoves, when we use them, warm the whole house. We have burnt wood from two trees felled in our own garden (both had grown too large) plus wood collected from a local tree surgeon. All reducing our heating costs and carbon footprint. Both stoves were chosen for their clean burn credentials but current scientific advice suggests we should not use them because of the contribution they make to air pollution.
Otherwise our main source of heat is a gas condensing boiler. To minimise our gas consumption and carbon footprint, we limit the hours when we run the boiler to an hour or so around breakfast time and for about four hours in the evening, turning the heating off about an hour before we go to bed. We heat only the rooms we use in the day time – kitchen, living room, study – plus the bathroom. We keep the thermostat at about 16C and wear several layers of clothes as necessary! Once the sun sets we draw the curtains in all the rooms, and these have thermal linings. In bed we have hot water bottles.
The boiler also provides hot water. When we upgraded the house’s insulation, we also replaced the bath with a low powered shower – think light rainfall. Over the last year we have cut back on daily showers, replacing them with a wash in the handbasin. The distance from the hot water cylinder to the kitchen sink is such that to get hot water, you need to draw several litres of colder water. As this ultimately waste hot water left in the pipe, we use a kettle to heat water for washing up. This saves about 5 litres of hot water a day.
This summer, given that we shower once or twice a week, we are cutting back further on gas by turning off the boiler. Instead we use the electric emersion heater when we do need hot water for showering. As we have solar panels, we aim to run the emersion heater when the sun is shining.
Our annual gas consumption for the last twelve months has been 6739 KWH and for electricity 1542 KWH.
