The hearth, which may be of brick, stone, tile, or concrete, must be supported by a masonry trimmer arch or similar fire-resisting construction. Both hearth and arch should be at least twenty inches wide and not less than two feet longer than the width of the fireplace opening.
If the mantel is of wood, it must not be placed within eight inches of the jambs, or twelve of the lintel.
The minimum height of chimneys above the roof line is two feet for hip, gable, or mansard roofs, and three for flat ones.
Chimney caps must not reduce the effective draft area of flues.
In connecting the smoke pipe of a heating plant, incinerator, or water heater to its flue in the chimney, the opening must be built with a fire clay tile collar and the smoke pipe should not protrude into the flue beyond the collar. Otherwise, the efficiency of the draft is materially impaired.
In addition, home owners may have other features installed that will do much to increase heat production of fireplaces and convenience in the use of them. One is the steel fireplace form, built into the chimney. This takes the place of jambs, back, throat, smoke shelf, and smoke chamber and is so designed that behind sides and back there is an air s.p.a.ce opening into the room through intake and outlet vents on either side of the fireplace. The cold air of the room is drawn into this s.p.a.ce, heated by radiation and returned. It acts on the order of a hot air furnace and can be used to advantage in new fireplaces or in old ones too much out of repair to be used without rebuilding.
There is also the sheet-steel smoke chamber which comes complete with throat damper and smoke shelf and is put in place above the lintel where it extends to the point where the flue commences. A common device for easy disposal of the ashes is the ash dump, a small cast-iron vault located in the fireplace floor and connected with an ash vault built in the chimney foundation. The vault is equipped with an iron door so that the ashes may be removed once or twice a year.
So much for chimneys and fireplaces. For actual and even heating of all parts of the house, some type of heating plant is necessary both for comfort and economy. It is true that our forefathers lived, many of them to a ripe old age, with only fireplaces to heat their drafty homes and with no heat at all in their public buildings. They did, however, fortify themselves well with a daily draft of rum and they wore a quant.i.ty of clothing that would be intolerable today. Further, plenty of wood for fuel grew at their very door; it was part of the normal farm work to cut it down and prepare it for the cavernous fireplaces.
But then, as now, a fireplace could only heat a comparatively small area. Further, under modern conditions, it is the most expensive heat that can be generated. Even though your holding includes a good sized wood-lot, the cost of labor for getting fuel cut, drawn, and piled in your cellar may run to more than the same amount purchased from the local coal yard.
If you have purchased an old house with no heating plant or are building a new house, the type of heating used will largely depend on what your architect considers practical and what you can pay for. The chief systems, viewed in descending order of expense, are hot water, steam, piped hot air, and the pipeless furnace. All of these can be fitted to burn either coal or oil.
Provided one can meet the initial expense of purchase and installation, the ideal system is probably the oil burning, electrically run, hot water heating system. Barring the final perfection of the robot, it is as near to a mechanical servant as one is likely to get even in this age of invention. There is no shoveling or sifting of ashes. There is no furnace shaking or stoking, no puzzling over dampers. Periodically and for a price, a man comes and fills the oil tank. A thermostat regulates the heat. You have only to set it for the desired temperature and forget it.
There is just one flaw with this perfect system. It is dependent on electricity. Let that fail and there is trouble. The fine copper radiators, so efficient when all goes well, spring leaks if the water in them freezes. A few years ago an unusually severe blizzard in the North Atlantic states worked havoc with all of the modern devices.
Roads were blocked, telephone and electric service lines were down, and even train service was impaired. One of our neighbors had built a new house two or three years before and equipped it with practically every appliance known to modern comfort, including an oil burner.
In a few short hours this blizzard had set him back more than a century. Electricity, of course, failed and the heat in his fine furnace dwindled and died. It grew colder and colder, ultimately reaching twenty degrees below zero. Added to the discomfort of the family was the disquieting knowledge that the freezing point would mean cracked radiators. Luckily he had three fireplaces that really worked. He had plenty of wood. So for three days and nights, he and two other members of his family worked in relays to keep roaring fires going in all three fireplaces. In this way they maintained a temperature of at least 40 degrees and so saved pipes and radiators.
One may argue that, if water freezing in radiators and pipes is all, why not drain them in such an emergency. This is a job for a plumber, as it must be done with a thoroughness that leaves no moisture behind.
The average layman has neither the skill nor the tools for it.
Therefore, if there comes a winter when snow, ice, high winds, and low temperatures cause you to wonder if living in the country the year around is quite sound and you decide that a few weeks in a nice city apartment would be a good idea, close your house, if it seems more expedient than leaving a caretaker behind, but don"t try to save the plumber"s fee. Remember pipes, radiators, and valves cannot be mended.
They have to be replaced and that is expensive.
However, blizzards that seriously interrupt electric service are so rare that one need not forego the decided comfort that an oil burner gives, just because some such chance may arise. Also, if the question of expense must be considered, steam can be used instead of hot water and will cost from one-quarter to one-third less.
The initial expenditure for both hot water and steam heating is considerably less, too, if coal rather than oil is to be the fuel.
This calls for quite a little more supervision on the part of the householder. He can cut down some of the drudgery of stoking by installing a gravity feed type of boiler. This is equipped with a hopper and needs filling only once a day. Or he can use the old fashioned hand-fired type, with or without the services of a man of all work. There will be dust and dirt as well as the morning and evening rituals of stoking, adjusting dampers, shaking, and cleaning out the ash pit. There will be the periodic ch.o.r.e of sifting ashes and carrying them out for either carting away or for filling in hollow places in the driveway. But his fire will burn, no matter what happens to the current of the local light and power company.
However, as already stated, electricity is a faithful servant most of the time and there are devices that not only take away some of the drudgery of furnace tending but, in the long run, actually save money in coal bills. One of these is the mechanical stoker which is electrically driven and burns the finest size of coal. Another way of reducing the coal bill is to install an electric blower. This, as its name implies, is a forced draft controlled by a thermostat, and with it the cheaper grades of coal can be used. Incidentally, any coal-burning furnace that gets to sulking can be made to respond by placing an ordinary electric fan before the open ash pit. We have done this with a pipeless furnace and have been able to burn the cheaper buckwheat coal almost entirely as a result.
There appears to be no mechanical device for removing the ashes out of the cellar. So, if the householder puts in a coal burning steam or hot water plant as a matter of economy, and then in a few years covets an oil burner, it is perfectly practical and possible to have one installed in his furnace. Whatever the fuel, make sure enough radiation is provided with steam or hot water plants to heat the house evenly and adequately in the coldest weather according to your ideas rather than the plumber"s. He is usually a hardy individual who considers 68 degrees warm enough for any one. Theoretically it may be.
Actually most people are more comfortable at a room temperature of from two to four degrees higher.
Cheapest of all to install and operate is the pipeless furnace. This is hardly more than a large stove set in the cellar. An ample register in the floor directly above it is connected to a galvanized iron casing that surrounds the fire pot. It is divided so that cool air from the house itself is drawn downward, heated, and then forced upward again. This system will not work well in a house equipped with wings or additions so placed that the air from the central register cannot penetrate. It is particularly effective in a house with a central hall.
In the 18th century compact house with central chimney, the pipeless furnace register can be set in the small front entrance and another register cut in the ceiling directly above it. This carries part of the heat to the second floor and so makes for better distribution of the warm air. As already stated, such a furnace is quite inexpensive and so easy to install that the average handy man will not find it too complicated. We put one in our country home some eight years ago merely as a means of keeping the house warm during the early spring and late fall. We have since found that it can and does heat the entire house even at sub-zero temperatures.
In all honesty, however, one must admit that it has certain disadvantages. First, it is like the old-fashioned stove in that an even heat is hard to maintain. Second, with coal or wood as the usual fuel, there is a discouraging amount of dust generated. Third, the doors to all rooms must be left open so that the currents of hot air can circulate. One chooses between frosty seclusion and balmy gregariousness. Yet, in spite of these very definite "outs," it is far better than no furnace at all. It is, in fact, an excellent stop gap for the country house owner who is not prepared to invest in the more expensive heating plants at the moment. The more effete system can always be added later and the faithful old pipeless junked, moved to some other building, or left in place for an emergency, such as a public-utility-crippling blizzard or flood.
THE QUESTION OF WATER SUPPLY
[Ill.u.s.tration]
_CHAPTER IX_
THE QUESTION OF WATER SUPPLY
Whether one lives in the country or the city, geology and geography govern the source of the water that flows from the tap. Cities go miles for an adequate, pure water supply and have been doing so since the days of the Caesars. Such systems involve thousands of acres and millions of dollars for water sheds, reservoirs, dams, pipe lines, and purifying plants.
The country place is a miniature munic.i.p.ality with its own water system. The latter need not be elaborate or expensive but it must be adequate. Nothing disrupts a family so quickly and completely as water shortage. Personally, we would far rather see our family hungry and in rags than again curtail its baths and showers. "We can be careful and only use what is necessary," sounds easy but before long everybody is against father. He is mean and unreasonable. Save the water, indeed!
It is all his fault. He should have known the supply would fail when he bought the place. A moron could see it was not large enough. A six weeks" drought? Well, what of it!
Meanwhile water diviners, well diggers and drillers add gall and wormwood to the situation. "Oh yes, that well always did go dry about this time of year. Saving the water wouldn"t make any difference.
Better not bother with it but dig or drill a new one." Expense? Why quibble about that when the peace of one"s family is at stake. There is, of course, only one outcome. A broken and chastened man soon makes the best terms he can with one of his tormentors. If he is wise it will be with the advocate of the driven well. That solves for all time any question of water supply.
Before deciding on a source, however, consider what the daily needs will be. From long observation, it has been found that the average country place requires fifty gallons of water a day for each member of the family, servants included. Then allow for two extra people so that the occasional guest, whose knowledge of water systems begins and ends with the turning of a faucet, will not unduly deplete the supply. For example, a family of seven should have a daily water supply of from 400 to 500 gallons depending on how much entertaining is done and how extensive are the outdoor uses. This allowance will be ample for toilets, baths, kitchen and laundry, as well as for moderate watering of the garden and lawn. Of course, if cars are to be washed regularly, fifty gallons should be added to the daily demand. If there is a swimming pool, its capacity should be figured by cubical content multiplied by seven and one-half (the number of gallons to the cubic foot) and allowance made for from fifteen to twenty-five per cent fresh water daily.
The daily production of a spring or drilled well can be easily gauged.
A flow of one gallon a minute produces 1,440 gallons in twenty-four hours. In other words, a flow of ten gallons a minute means 14,400 gallons a day which, at fifteen gallons a bath or shower, is enough water to wash a regiment from the colonel to the newest recruit.
Estimating the daily production of a shallow, dug well is more difficult. The number of gallons standing in it can be obtained by using the mathematical formula for the contents of a cylinder, but only observation will tell how quickly the well replenishes itself when pumped dry. By long experience, however, country plumbers have found that if such a well contains five feet of water in extremely dry weather, it can be relied upon for the needed fifty gallons a day each for a family of seven with enough over for safety.
In fact, with all water sources except an artesian or driven well, the question always is, will it last during an abnormally rainless season?
Never-failing springs and wells that never go dry are inst.i.tutions in any countryside. So consult some of the oldest inhabitants. They know and if they give your well or spring a good character, the chances are that even the most exacting of families will find such a water supply adequate. Whether it is pure or not is another matter but one that can easily be determined by sending a sample to your state health department or a bacteriological laboratory. That this should be done before such water is used for drinking purposes goes without saying.
The driven or artesian well has two points that makes it worth the cost. There is no question of purity or of quant.i.ty. It taps subterranean water which is unaffected by local causes of contamination or by drought.
The kind of water system, like the supply, is governed by geography and geology. If there happens to be a spring on a nearby hillside somewhat higher than the house, nature has provided the cheapest and simplest system. A pipe line and storage tank are all that are needed.
Gravity does the rest. On the other hand, if the spring is on the same level or lower than the house, a pump must be added to the equipment to force the water into the pressure tank and out of the faucets. If the spring has a large flow and adequate drainage, a water ram is advisable. With this hydraulic machine, three-quarters of the water that flows into it is used to force the balance into the storage tank.
The expense of operation is nothing and as water rams and pumps cost about the same, such an installation has much to recommend it.
When the search for water goes below ground, one must reckon with geology. What lies below the turf is the deciding factor. If it is sand and gravel with a high water table (the level of subterranean water), an excellent well can be had cheaply. The practice is either to bore through to the water table with a man-operated auger and then insert the pipe, or to drive the latter down with a heavy sledge hammer. In either case, water is but a few feet below ground and a shallow-well pump, which can raise water twenty-two feet by suction, will be adequate.
There are two types of well to be considered with less favorable subsoil formations--the shallow and the artesian. With the former (known to country people as a dug well) a shaft from six to ten feet across is dug with pick and shovel until adequate water is reached.
Then the shaft is lined with stone laid without cement or mortar up to a few feet from the top. This allows water from the surrounding area to seep into the well where it is retained until it is drawn upward by the pump. It is obvious that a well of this type cannot be built through ledge or solid rock. In fact, unusually large boulders sometimes force diggers to abandon a shaft and start afresh. An old house with two or three of these shallow wells on the premises serves notice on the prospective buyer that repeated and probably unsuccessful attempts have been made to find a well that does not go dry.
Dug wells are seldom deeper than fifty feet; the majority are but little beyond twenty-two feet, the suction limit for a shallow-well pump. As is obvious from their construction, they depend on the water in the upper layers of the subsoil and so are more readily affected by dry weather. Although not drought-proof like the artesian, a dug well, which costs much less, can be an excellent water source and supply amazingly large quant.i.ties of water.
We have lived for ten years in a house served by a shallow well credited with being never failing and it has faithfully lived up to its reputation, even through the driest of seasons. Once, however, it made real trouble. Over it stood a picturesque latticed well house. On one of the beams a pair of robins nested annually. In the middle of the third summer the water developed a queer flavor. It steadily grew stronger until one night the steam arising from a hot bath caused the pajama-clad head of the house to seize a flashlight and move hastily to the well house. One beam of light disclosed the horrid truth.
Floating in the water far below were two very dead fledglings.
The next day a well cleaner collected twenty-five dollars for removing the birds and pumping out the well. He also gave some excellent advice which was followed promptly. The well house, picturesque though it was, gave way to a substantial masonry curbing equipped with a stout wire cover. The peace of mind so gained has more than offset the trifling expense. No longer need one peer fearfully down a twenty-five foot shaft when a pet cat fails to show up for a meal, or shoo away from the spot the over-inquisitive offspring of visiting friends.
The drilled well, against which there is no possible argument save that of cost, is made by boring a hole in the ground with a powerful apparatus until sufficient subterranean water is reached. There are two methods, the chop and the core drill. With the former, a cutting tool exactly like the drill used to drive holes in rocks for blasting, only larger, cuts a circular hole downward. The boom of the drilling rig as it raises and drops the drill provides the necessary impact.
