Making an economical homemade water heater

Sometimes a homemade water heater is a great option to save on the necessary expensive equipment. It can be used as a temporary option in case of breakdown of the old equipment, or on a permanent basis, for example, in country houseswhere the need for hot water is seasonal. Of course, for permanent water supply in a private house or apartment, it is best to use factory systems. The manufacture and installation of a homemade device for heating water does not require special experience, it can make any. The main thing is the availability of the necessary material and tools for work. So, how to make a water heater with your own hands?

Pressure or non-pressure version

Of course, self-made storage pressure water heaters, designed by yourself, will be more convenient to use. But for their assembly requires additional investments and knowledge. Such systems should be equipped circulating pumpin order to maintain a pressure of 1 atm or connect to the water supply system already in the house.

If the budget is limited and there is no possibility to purchase such additional equipment, or there is no water supply system in the house at all, you should pay attention to the free-flow option. Such a water heater with your own hands can be made from an ordinary bucket or large-capacity saucepan. The main thing is to mount such a device higher so that water runs out of it. under the force of gravity. But it is necessary to monitor all the time the filling of the storage tank and the temperature of the water.

Since in such an improvised device it is difficult to provide a mixing system, it is necessary to heat the water initially no higher than 40 degrees.

What to make storage tank

Before you make a water heater, you must determine the design features of the future boiler.Most often, it is an accumulative tank with a heater installed inside it, which is responsible for heating water.

For an accumulation tank, it is better to choose containers from a metal that is resistant to corrosion. The most suitable options: stainless or enameled steel, high-quality plastic, aluminum. Iron tanks can also be used, only they will have to be pre-treated with a special protective compound, which minimizes rust formation. Otherwise, the water passing through such a heating device may not be suitable for domestic use.

For self-made storage water heaters use a variety of containers, as an example, you can note the gas cylinder. It is quite convenient in size, shape and strength of the tank.

How to make a water heater from a gas cylinder

Ideally, for this will be purchased a new vessel. If this is not possible, use a used cylinder. To get rid of the smell of gas, it should be carefully nitrate and rinse the inside surface. To do this, the cylinder will have to first cut and then cook again.

It is worth paying special attention that before performing work that will be associated with violation of the integrity of the container, it must be filled with water to eliminate the possibility of an explosion.

Tools and materials:

• welding machine and drill for metal;
• metal-cutting tool for applying thread (die);
• screwdrivers and gas wrench;
• empty gas cylinder;
• heating element with a thermostat;
• insulating composition for the heater (grease or tow);
• metal liner;
• nut, safety and check valves;
• fasteners for fixing the finished boiler.

Instructions for making.

1. In a clean, prepared for the operation of the cylinder, using a drill and nozzles for metal are performed two holes: at the bottom - for water intake, at the top - for the exit of water heated to the desired temperature. Such an arrangement of the holes contributes to the most efficient operation of the water-heating equipment. This is explained by the fact that hot water rises according to the laws of physics, respectively, the maximum temperature of the liquid will be in the upper part. It is possible to make both holes on one side (where the gas valve is located), and between them a heating element will be installed.This design will resemble standard mounted water heaters.
   
2. Welded tube. It is worth noting that if both holes are made from below, the tube through which the hot water will be taken must have a length corresponding to the size of the tank. It is necessary that the output water had a maximum heating temperature.
3. Installed taps. A check valve is connected to a faucet that is designed for cold water - it will prevent the return of cold liquid. On the hot faucet is installed safety valve. It performs protective functions: prevents depressurization of the tank with water due to pressure, releases excess liquid, because when heated, water increases its volume by 2-3%. It also allows you to drain the water to dismantle the structure.
   
4. A heating element is installed at the place of fixing the gas valve. To do this, cut the thread size of 32 mm. TEN group is isolated by tow. For convenience, the LED should be hooked up here during operation - it will signal the operation of the heating element.
5. Self-made boiler should have a good heat insulation layerto minimize heat loss. For these purposes, you can use: mounting foam, izolon, polyurethane foam, foil substrate, foam. The selected material is mounted on the cylinder, the casing of thin metal is put on top.
6. The finished electric water heater is mounted on the wall with brackets.
7. Now you can connect metal pipes to the water holes, which are attached to the water pipes.
   

Water heater with his own hands almost ready. Now the device can be filled with water and checked for leaks. If all is well, you can connect the heater and use the device.

Economical water heater do it yourself

The constant increase in electricity tariffs makes it necessary to switch to saving mode for many consumers. A good option - a cumulative boiler with his own hands, working on solar energy.

For its manufacture will require:

• accumulation tank of large volume (100-200 liters);
• PVC pipes and hoses for water supply;
• fasteners.

Instructions on how to make an economical boiler for the dacha:

• holes are made in the accumulation barrel for the nozzles;
• hoses are connected to them;
• the capacitive tank is installed in a sunny place protected from the wind;
• water supply is organized (it can be a hose connected to the water supply system);
• A conclusion is made on a tap or a summer shower.

Under the action of sunlight the water in the barrel heats up and can be used for your needs.. This is a practical option for organizing a summer shower in your garden. Often these barrels are installed directly on the roof of various buildings. To maximize the use of natural energy and to achieve maximum efficiency from such a device, next to the reservoir in which the water is located reflective elements (for example, remnants of foil substrate for laminate), or the tank itself should be painted in a dark color.

If desired, any water heater can do it yourself. The main thing is to think over the design features of the equipment in advance, select suitable materials and secure the water heating system.
