The Complete Home Part 5

ADAPTABILITY

Electricity's strong card is its adaptability. It can go wherever a wire may be carried, and into many places where gas or oil lights would not be safe or practical. The only thing lacking is to make it wireless, and perhaps invention sooner or later will be equal to that demand. Early installations were rather carelessly made, but munic.i.p.al and underwriters' rules are now so strict that practically all danger of fire has been eliminated. The householder in the country should make sure that the underwriters' prescriptions are fully observed, as his insurance may be affected. In the city, official inspection usually guarantees correct wiring.

Probably only in the hall, dining room, and living room will we be greatly concerned with the decorative phase of lighting. Elsewhere the question is largely one of practical use, though considerations of taste are not to be neglected. Careful study should be given to the adaptation of lighting to the future uses of the rooms. This will perhaps avoid the use later of unsightly extension cord, though this avoidance can scarcely be made complete.

PROTECTION

A very useful light may be provided for the veranda, just outside the door, illuminating the front steps and path to the sidewalk. This light may be turned off and on by a switch key inside the door. It is particularly comforting when some stranger rings the doorbell late at night and one does not feel overpleased to be called upon to open the door to an invisible person. Other switch arrangements make it possible to turn on the upper hall lights from below, or the lower hall lights from above, and the lights in each room from the hall. When there are unseemly noises downstairs in the wee sma' hours it is much more agreeable to gaze over the bal.u.s.trade into a bright hall than to go prowling about in the darkness for the bulb or gas jet, with the chance of grasping a burglar instead. Some burglars are very sensitive about familiarities on the part of strangers, and it is always better to permit them to depart in a good humor. The bas.e.m.e.nt lighting, too, should be regulated from above, and the dark corners should be well looked after. At best, the bas.e.m.e.nt is a breeder of trouble. If the light is in the center, and must be turned off at the bulb, the return to the stairway from the nocturnal visit to the furnace is likely to be productive of bruised s.h.i.+ns and objurgative English; if the light operates from above, one either forgets to turn it off and leaves it to burn all night, or becomes uncertain about it just as he is beginning to doze off, necessitating a scramble downstairs to make sure. Perhaps it would be well to have a choice of systems.

Some houses have been so wired that one can illuminate every room from the hall or from the master's bedroom. This necessitates complicated wiring and will not be found necessary by most of us. Neither will we desire to spend our hardly won cash in wiring our four-poster bed for reading lights, or to put lights under the dining table for use in searching for the lost articles that always by some instinct seek the darkest spots in the room. If there be a barn or shed on the lot, an extension carried there will be found convenient and comparatively inexpensive. In the kitchen and pantries the lights should be considered in detail so that all the various operations may be served.

Shadowed sinks and ranges and dark pantries are not necessary where there is electric light.

REGULATED LIGHT

In halls, closets, and bathroom lower-power lamps, or the "hylo," which may be alternated from one- to sixteen-candle power, will prove an economy. The "hylo" is also useful in bedrooms where children are put to sleep, affording sufficient light to daunt the hobgoblins without discouraging the approach of the sandman. Some persons cannot sleep without a light; for them, and for the sick room, the low-power light is eminently preferable to the best of oil lamps.

There are numerous conveniences to be operated by electricity, such as chafing dishes ($13.50), flat irons ($3.75 up), curling-iron heaters ($2.25 up), electric combs for drying hair ($4), heating pads, in lieu of hot-water bags ($5), and many articles for the kitchen. These are operated from flush receptacles in baseboards or under rugs, or from the ordinary light sockets.

THE TWO SURE WAYS OF HEATING

There is only one efficient and healthful method of heating a house, and that is with a hot-air furnace. I have that on the authority of a man who sells hot-air furnaces, and he ought to know.

Subst.i.tute "steam or hot water" for "hot-air furnace," and we have the a.s.surance of the man across the way who sells boilers and radiators.

The beauty of it is that each proves his case to one's entire satisfaction--not only that his own system is a marvel of perfection, but that the other systems are dangerous to health and breeders of unhappiness and really ought (though he wouldn't like to say so) to be prohibited by law.

So we shall have to decide the question for ourselves. If we err, we can still abuse the dealer, or the architect, or the contractor, for letting us make a mistake.

THE HOT-AIR FURNACE

The hot-air furnace costs least to install. (We leave stoves out of consideration.) It is also supposed to be easiest to manage. That, in a sense, is true. A good furnace will act pretty well even under indifferent direction; a bad one cannot be made much worse by the greatest of stupidity.

However, the average person can run the average furnace with a fair degree of satisfaction to the household, if not to himself. For a house of six to eight rooms the furnace may be considered an efficient means of heating. It requires more fuel than some other apparatus, but there are compensations.

Since ventilation and heating are inevitably a.s.sociated, the argument that the furnace provides for ventilation is a strong one. If the air is taken from outdoors, pa.s.sed over the radiating surface into the rooms, and then sent on its way, something like perfect ventilation is a.s.sured. If the air is simply taken from the bas.e.m.e.nt--a poor place to go for air--heated, pa.s.sed through the rooms, returned, and heated over again, we may well pray to be delivered from such "ventilation." The success of the furnace depends not upon ability to keep up a rousing fire but upon a proper regulation of air currents. Many a first-cla.s.s furnace, properly installed, fails to work satisfactorily because the principle of heating is not understood. Even with the best of knowledge, the air is hard to regulate, and the very principle that gives the furnace its standing as a ventilator must prevent it from being a perfect heater.

Unless some artificial moisture is provided, not only will the air be too dry for comfort and health, but an excessive degree of heat must be attained in order to warm the rooms, thus increasing the consumption of coal. A water pan is usually provided in the furnace, but too often it is neglected.

DIRECTION OF HEAT

If any mistake in selection of size is to be made, it should be in favor of excess. Most authorities urge the choice of at least a size above that indicated by the heating area. A chimney with suitable draught is imperative. The furnace should be placed in a central location and should be set sufficiently low to permit the essential rise of the heat ducts. If the bas.e.m.e.nt is low the furnace should be depressed. While the heat conveyors should not ascend directly from the furnace, they should not be carried any farther than necessary in a horizontal position. The velocity of heat is diminished in carrying it horizontally, increased vertically. Crooks and turns add to the friction and decrease heating power. Therefore the pipes should be as short and direct as possible. It is not necessary to carry the register to a window on the farther side of the room, say some authorities, as the warm air rises to the ceiling anyway, and the greater length of carry involves a loss in warmth.

Pipes for the first floor should he large. Those for the upper rooms, having a longer vertical range, may be smaller. All the pipes should be double, with an inch air s.p.a.ce between, as a protection against fire. Asbestos paper on a single pipe is not regarded as a sufficient precaution, as it is easily torn and quickly wears out.

REGISTERS

There are arguments in favor of side-wall registers. They save floor s.p.a.ce and obviate some dust. On the other hand, they are not quite so effective in heating as the other sort, since the pipes for floor registers may be of larger diameter and as a rule require fewer bends.

Each register should have a separate pipe from the furnace. Where direct heat is not desired, a register opening in the ceiling of a downstairs room will sometimes carry enough heat to the upper chamber to make it comfortable for sleeping purposes.

Since furnace efficiency is largely dependent upon air control, a strong wind sometimes makes it difficult to heat portions of the house.

To meet this emergency there is a combination hot-air and hot-water heater which supplies radiators on the upper floors, or elsewhere if desired. The additional cost is practically all in the installation, as the same fire furnishes both forms of heat.

For an eight-room house or smaller, a first-cla.s.s steel-plate furnace, securely sealed against the escape of gas and smoke, costs free on board about $150. Each two rooms additional raises the price about $25. Other furnaces may be had as low as $50. Cost of tin work, brick setting, etc., depends upon locality.

HOT WATER AND STEAM HEAT

Hot water and steam heat cost more for installation, but have many advantages over the furnace. Their chief drawbacks are the s.p.a.ce usurped by radiators, lack of ventilation, and the possibility of an occasional breakdown. The ingenuity of the makers, however, is partly overcoming these difficulties, mainly by the device called the indirect system.

We need not fret ourselves here with a technical elucidation of either form of heating. We may, however, consider some of the claims made for hot water, which is apparently coming to be considered the preferable arrangement for dwelling houses. There is not a great deal of difference between the essential features of steam and hot-water systems.

It is declared that water will absorb more heat than any other substance, hence will take from the boiler practically all the heat produced in the combustion of fuel. As the temperature of the water is automatically controlled, the atmosphere of the rooms may be kept at the desired degree, the presence of radiators in each room, all of the same temperature, giving an even heat over the entire house.

There can be no sudden drop in temperature, as the water in the pipes continues to distribute warmth even after the fire has been checked or has been allowed to go out. The fuel required for an ordinary stove, it is a.s.serted, will warm an entire house with hot water. An engineer is not required. Inexperienced persons have no difficulty in operating the ordinary boiler, and there is no danger whatever, because, the makers adduce, for steam heat the maximum pressure is about five pounds, while with hot water there is practically no pressure at all.

Very little water is used, and a connection with the street water system is not imperative, though convenient.

INDIRECT HEATING

Indirect heating is provided by pa.s.sing air over radiators attached to the ceiling of the bas.e.m.e.nt, thence to the upper rooms. In the "direct-indirect" system the radiators are placed in the part.i.tion walls of the rooms they are to heat, the cold air being brought through a duct and, being heated, pa.s.sing into the rooms. These two systems are economical of s.p.a.ce and afford provision for excellent ventilation.

They are considerably more expensive, however, than the direct system, which involves exposed radiators.

Radiators are now constructed in many different forms, to fit under windows, in corners, in fireplaces, under cabinets, and so on. Much effort has been directed also toward relieving their painful ugliness, and if of a neat design appropriately colored they need not be a serious blot upon the decorative scheme of a room.

Radiators, in the direct system, should be placed far enough from the walls to permit free circulation over the heating surfaces, and should not be directly covered at the top. Ordinarily there are good reasons for putting them near the more exposed places, such as windows and outer doors. As both steam and hot water furnish a dry heat, provision should be made in every room for evaporation of water.

SUMMARY

With no prejudice against good furnaces, it may be said that hot water apparently affords the greatest possibilities for comfort and regularity of heating, and that there are usually no reasons why it cannot be utilized in country houses. A hot-water installation is likely to cost twice as much as a furnace, but if we are to live in the house it is better to make our estimates cover ten or twenty years rather than to bear too strongly on first costs.
