I wash all our clothes on cold. Even whites.
I have a spin dryer instead of a tumble dryer.
I'm replacing all the light bulbs with LED bulbs. Even the one in the fridge is LED.
I use a halogen oven instead of the inbuilt oven. It cooks better than a conventional oven.
I cook on an induction hob with a timer, it switches the ring off when the timers up.
The water heats for 20 mins to 55c.
Nothing is stored in the loft so the insulation works properly.
I buy thermal linings for curtains, curtains shut at dusk.
All the doors have brush draught excluders on them.
Our heating only goes on when we are in, no point heating a house if you aren't there.
All the radiators have radflex foil panels fitted.
Doors shut on rooms that are heated.
I have thermal leggings, long sleeved tops & long sleeved vests and heat holder socks to wear in the winter. If you buy M&S ones in the clearence they are really comfy, better than cheap ones from the supermarket.
We both have fleece dressing gowns, much warmer than towelling ones. Mines extra long so it's toasty.
Shower water saving device fitted, free off the water board & I switch it off while I'm soaping up or washing my hair.
Kettle de-scaled weekly so it doesn't have to work harder to boil.
Slow cooker for cooking whole chickens, much cheaper than using the oven.
All the hot water pipes surrounding the tank that get warm are lagged with thick foam, almost no heat is generated from the cupboard unlike previous houses we've had that have pumped the heat out which is very wasteful.
We've got an E-Cloth mop so no big bucket of water is needed for the floor. Dh used to boil 3 kettles to mop the floor
.
The fridge and freezer are run on the lowest settings, freezer defrosted monthly. We don't leave the door open ages either.
