Here in the UK with the current cold weather set to continue here are some tips to help keep warm while keeping the cost of heating your house down.
Eliminate draughts and wasted heat by installing a cheap, easy-to-fix brush or PVC seal on your exterior doors.
Letterboxes and keyholes should be covered, too, and do not leave the front door open more than necessary.
Draughts also get in through gaps in floorboards and skirting boards, which allows heat to escape in the winter months. Filling them with newspaper, beading or sealant will help you stop throwing heat (and your money) away.
An insulating jacket for a hot water tank only costs a few pounds and pays for itself within months. Fit one that is at least 75mm (3") thick and start saving both money and carbon.
Insulating your loft is one of the simplest ways to save energy. By installing loft insulation to a depth of at least 270mm (10").
Around 33% of the heat lost in your home is through the walls, so insulating them can be one of the most cost-effective way to save energy in the home.
Cavity wall insulation will also keep you cool in the summer and warm in winter. It's straight forward, inexpensive and hassle-free.
