What is the biggest pit where a water heater is installed? You probably don't even think about it – install. When you buy a water heater, in order to make you feel cheap, the merchant will promise to install your home for free, but in fact, if you believe the merchant's words and are unprepared, the additional installation cost of less than tens or hundreds is spent!
How to avoid all kinds of "adding money", "adding money" and "adding money" when installing water heaters? As a passer-by, I have sorted out the following 5 materials that need to be prepared in advance before installation, and buying them can save you money:
1. One smoke exhaust pipe
The situation varies from brand to brand, some water heaters will come with smoke exhaust pipes, and some do not. Even if the water heater you buy has a smoke exhaust pipe, you should pay attention to whether the length is sufficient according to your own installation, and also pay attention to whether the diameter of the smoke exhaust pipe is 50 or 60.
Recommendation: Pay attention to choosing the appropriate material and specifications. The materials of the exhaust pipe are PVC and stainless steel, which can be selected according to your needs and budget. In addition, it should be noted that the caliber of the smoke exhaust pipe should match the caliber of the water heater smoke outlet to ensure that the smoke is installed smoothly and the smoke is discharged smoothly.
2. One hot and cold water for angle valve
The water heater will not come with its own angle valve, but this is a necessary accessory, many friends did not prepare in advance, temporary installation to know the need, just use the master brought by, not only expensive quality but also very general, the money spent is not worth it.
Suggestion:
(1) Pay attention to the purchase of ball valves, including 1 hot and cold water. Because the ball valve has a larger water output, it ensures normal water supply.
(2) Pay attention to choosing the specifications and models that match the water heater. Generally speaking, the angle valve specification of domestic water heaters is DN20, and it is necessary to ensure that it matches the diameter of the water heater inlet and outlet when purchasing.
(3) Also pay attention to the material of the angle valve, choose copper or stainless steel material, it is best to choose the brand, long service life, higher safety.
3. Two explosion-proof bellows
Most brands of water heaters come with bellows, but the length is often only 15 cm, and in reality this length is often not enough, usually 30 or 40 cm is enough. If you do not prepare in advance, you can only use the installation master's own one, two bellows charge you at least a hundred yuan, in fact, if you buy it yourself, it will be thirty or forty.
Recommendation: Choose 304 stainless steel bendable, pay attention to choose the appropriate length and thickness to ensure that it will not break due to excessive pressure during use. In addition, when installing, ensure that the bellows connection is well sealed to prevent gas leakage, usually after installation, it is to be tested.
4. Stainless steel elbow and decorative cover
Stainless steel elbows and decorative covers are not needed by families, but with these two things can make the pipes of the water heater more beautiful, so you need to choose to buy according to your own installation.
Suggestion: Pay attention to choosing the right specifications and models, of which the specifications of the stainless steel elbow should be selected according to the diameter of the water heater inlet and outlet, and the decorative cover should be selected according to the external dimensions of the water heater.
In addition, pay attention to the material of the elbow and decorative cover, it is best to choose 304 stainless steel, which is more durable.
5. Punch holes
Most kitchen water heater smoke exhaust holes need to be punched by themselves, this hole if you plan and punch in advance in the hard installation stage, a hole of 50 pieces of man-hours can be done, if it is the installation of the water heater when you think of letting the installation master punch the hole, a hole less 100 yuan no one does.
Suggestion: The holes that need to be punched for water heater installation include water inlet and outlet outlets, smoke vents and power line ports. Before punching, mark the position with a pencil and then drill with a suitable drill. During the drilling process, care should be taken to keep the drill bit stable and vertical to prevent the drilling from deflecting or damaging the tile.
Note!!! If you are not sure of the specifications of auxiliary materials you need when installing a water heater in your home, you can buy a few more specifications and add a freight insurance, generally unused can be refunded. In addition, when buying auxiliary materials, pay attention to choosing a reliable brand, it is recommended to buy online, the price will be more affordable.
In short, when purchasing a water heater, in order to avoid additional costs during the installation process, you can prepare the above 5 installation materials in advance to ensure a smooth installation process after the master arrives. At the same time, by preparing auxiliary materials in advance, you can save installation costs and avoid being "cut leeks" by merchants.
