00:16 These days a warm and comfortable home is no longer a luxury, but an essential part of our everyday life.
00:24 And in industry, heat plays an important part in many processes.
00:29 For years, coal was cheap and provided our warmth at home and the heat for industry.
00:34 But with what result? A smoke-filled, dirty atmosphere.
00:39 More important still is the effect on our health.
00:42 The water we drink is purified at great cost.
00:46 We take considerable care to clean food carefully before we eat it.
00:50 But whilst drinking and eating are integral parts of our daily lives, breathing is an unconscious act.
00:56 A pity, for as we breathe in the dirt, it stays in the lungs and contributes to ill health,
01:02 and in foggy weather can result in disease and death.
01:05 It's only rarely that the town dweller can escape to the countryside or to the sea,
01:10 where he's able to breathe pure, clean air.

01:23 Smoke abatement is not entirely new. There have been regulations controlling industrial smoke to some extent for many years.
01:30 Industry has realised that smoke means wasted fuel and some effort has been made to eliminate waste.
01:36 But now the Clean Air Act has accelerated the whole process, and not only for industry.
01:41 For although you may think industry is the main culprit,
01:44 in fact almost half the total smoke in the atmosphere is produced from ordinary domestic chimneys.
01:50 That's why you'll be asked to play your part when your district is made a smoke control area.
01:55 How are you affected if your house is in a smoke control area?
01:58 Well the first important thing is that you won't be able to get supplies of ordinary coal, only authorised fuels.
02:05 This means your coal-burning fire grates have to be replaced by coke, gas or electricity.
02:13 After a survey you'll be given notice by the council and you'll have to convert your coal-burning grates.
02:19 Whatever you choose, a substantial part of the cost of conversion will be paid as a grant by the council.
02:24 The choice of fuel is entirely yours.
02:27 But if you're out at work or school all day, then you may prefer the convenience of an electric fire.
02:33 Switching on when you come in, there is straight away a welcome warmth.
02:38 And of course electricity is ideal for automatic control, to switch on the warmth before you come home.
02:45 Perhaps you're building a new house. If so, electric floor warming, one of the simplest methods of space heating,
02:51 is economical both in first cost and in running cost.
02:54 But for old or new houses, it isn't only for warming your rooms that heat is needed.
02:59 Plenty of hot water is not only necessary, it's a real aid to the housewife.
03:04 Smokeless water heating and electric immersion heater in the cylinder gives all the hot water you need.
03:09 Electricity for cooking is not only clean, but it's also a great time and labour saver.
03:14 And it can be fully automatic.
03:16 It's simplicity itself for the housewife who is away all day.
03:20 In the morning she can prepare the evening meal, place it in the oven, set the time switch,
03:24 and then go off for the day without any cooking cares.
