Soldering Copper Tubing - Step by Step

Good evening team! Today we will be going over the step by step procedure to solder copper tubing. 

We will go over what tools and materials you will need and then we will move on to the steps to get the job done. Let's get started!
Ok, so for getting this project done you will need:

1) Soldering Flux and a Brush
2) A cleaning tool or cleaning pad
3) Tubing and corresponding fittings
4) Solder
5) Some rags
6) Protective equipment, which include goggles 
7) A soldering torch

Steps to get it done:

1) You would like to get straight to soldering, right? We understand. However, the very first step before soldering has to do with preparation of your soldering copper tubing. Using a wire brush or cleaning pad, make sure to clean inside the hub on each fitting. Whether it is tubing with 1/2 in or 3/4 in diameter tubing, it is extremely useful to clean the interior of the hub as well as the outside of the tubing.

2) The second step is going straight to welding, Just kidding. It also involves more cleaning. After the tubing has been cleaned, use a tubing brush to clean the ends of all tubing sections. You can also use an abrasive pad to clean the tubing.

3) Thirdly, it is time for the flux application. Apply flux to both the inside of the fittings and also the tubing. To do this, you can use a small brush. After all the fittings and tubing insides and ends have been covered with flux, push the tubing into the fittings. 

4) Now that the tubing and fittings are together, it is time to prepare your solder and have a section of around 20" wrapped around you hand, ready to go. Also, as part of this step, remove the shutoff valves before soldering as these can contain plastic and rubber parts that can be damaged. 

5) Now we get to the part that you have been waiting! Soldering. In this step, start soldering at lowest point. You should direct the tip of the torch flame to both sides of the fitting and then press the solder against the join on the fitting and tubing. You can redirect the flame alternatively between both sides of the fitting. Thanks to the flux, the solder will flow toward the places where it is needed! The magic of Flux. 

6) The next step is to be very careful with how much solder you apply. If you apply too much solder, the solder will begin to spill. So, be very careful to notice the solder so that no solder starts to spill. If it does, then quickly use a rag to wipe away the damp rag.

Radiant Floor Heating - Number 2

Image
In the last post we talked a little about the first of five top radiant floor heating systems: Nuheat floor mats. We learned how they are easy to install and contribute to reducing heating costs. Today we will cover a second system. This system is the SunTouch tape mat. You can install this radiant floor mat before you place the final flooring over the top. The SunTouch system comes with everything you need: - the radiant floor heating map - a programmable touchscreen thermostat - sensor wire - installation alarm (a continuity monitor) - and double stick tape To install the map you just have to: - unroll and attach your att - secure the floor sensor - apply thin-set mortar - and install your flooring It is recommended that you plan your layout well. Measure and draw a layout simple plan before installation. The recommended installation temperature is 50 degrees farenheit or 10 degrees celcius.

Hello everyone. Today we have an important question from our audience. The question today is, How can you prevent fires? Seems like a question with a straightforward answer, but let's advance our awareness today!   First of all, preventing a fire is something that has tremendous value, as a fire can spread in devastating ways and put your family in great risk. Some of the most common reasons for fires are: electrical sparks, space heaters, and children playing with matches. In order to prevent fires, tools that you may need are: a CO and Smoke alarm, a combustible gas detection, a carbon monoxide alarm, a fire extinguisher, and batteries. Here are a few tips to help minimize the probabilities of a fire: 1) Never leave your space heater unattended. Also, make sure to leave the space heater at least three feet away from flammable material and on level surface. 2) Do not leave light candles near materials that can ignite. 3) Use a fireplace screen so that sparks can be kep...

Radiant Heating Systems: Installation Cost, Installation Time, Other Considerations

Image
Hello Team, How are you guys doing today? We hope that you all are doing fine during this difficult times. Indeed, we all have been going through much stress and anxiety and uncertainty. In the last few posts, we have been covering details about how radiant heating systems work with different flooring types, form vinyl to concrete to laminate floors. Today, we will cover three more topics regarding radiant heating systems. The first one will be installation costs. Of course, as in many other things in life, a specific answer is impossible to give. The factors to consider are the type of system that you choose for your home and the size of your home. As a general rule, installing your radiant floor heating will range between $10 to $30 per square foot. Again, this depends a lot on the type of system that you want to install and the difficulty of the installation. In addition to this labor part, you will also need to pay an electrician to connect the system to your hour...
