A common HVAC job that most homeowners can handle is installing heating. In order to install a heater, you must run an electrical circuit that is dedicated to the heater. This usually happens to a junction box in the wall.
Turn off the power to the circuit you're working on via the panel for breakers. Be sure you are licensed and have all the necessary tools for the work.
Installation
Installation of a heater is a plumbing project and requires a permit (if necessary in your location). Direct venting or powered venting might be required for some installations. This can be more challenging and should be left to experts. Install the temperature and pressure relief valve as well as drain line and follow your heating system's instructions to install it and the local codes.
In order to install a heater onto the wall requires the addition of the locking bar from the mounting kit. External locking screws are inserted into the hole in the left-hand side of the vent pipe at the lower end. 5). Be careful not to screw the screw into too tightly as this could block the left-hand mounting clip, causing that the heater not to sit perfectly in its mount.
The heater is then fixed to the wall with the screws provided at the top two anchoring places. The way to do this is as shown in Fig.3 Make sure that the clips are aligned to ensure that the arrows point towards the upward direction. 3 illustration.
Wire
The wiring of heating elements is an electrical task that requires the help of a licensed electrician. Electrical work that involves electricity should be completed with the help of a qualified professional, as the wires are live that may cause shocks and fires. Also, it is important that you follow national and local electrical codes. Apply for permits and inspect the work.
During this step in this process, the first thing you need to do is shut off electricity to the previous unit. After that, you need to drain the tank through a bucket, and then remove the electrical wires by unscrewing the terminal screws. Connect the new heater as per the specifications of the manufacturer. If the wires from the previous heater are way too far away from the new heater, mount an electrical device made of steel to the ceiling or wall next to the heater. Then, run the electrical wires to the box. It's recommended to place a shutoff device in the vicinity of the heater.
Most residential heaters use 240 volt lines. The heater will need a special circuit that has three wires (two 240 volt and the ground) to be installed in the panel for service. Check that the new circuit is correctly sized, by consulting the heater installation manual for specific specifications for amperage and watts.
Heating wires usually consist of an alloy called Nichrome which is typically composed of 80 % nickel, and 20 percent chromium. The Nichrome alloy is extremely resistant and a very high melting point as well as being abrasion resistant. It's crucial to know that nichrome wire doesn't have the negative and positive poles but is one of the resistive circuits.
After the breaker is properly sized, connect the two 240 volt lines together to the heater. Connect the ground wire to the breakers. Code requires that the ground wire is always connected to metal pipes or conduits.
Keep in mind that both the wiring for the breaker and heater needs to be grounded or linked to an earthing system. Carbon monoxide is a deadly poison when you don't connect the heater and breaker wires. The breaker and heater wires must be grounded to prevent carbon monoxide. Also, it is a good option to have an experienced electrician check the grounding system before the heating is turned on.
Connectivity
The last step to take after having removed the heater you have been using is connecting it with the new model. Close the gas and water supply valves before beginning work. It will stop any water leakage or damage. You may also want to switch off electricity making use of a switch for a service disconnect within the reach of the heater or a circuit breaker. If you've got a voltage of 240 volts test light, it's a good idea to use it before reaching any wires with no insulation because they may cause serious injuries or even death.
You might have thermoplastic copper, or sweat-soldered pipe according to the type of piping that you are using in your residence. Install a cold-water gate valve at the point where the pipe joins the heater, heater installation regardless of material. The valve will block dirt from getting into the water system. Install a flare or union fitting on the gas line that connects to the heater when you are using a liquid that is flammable.
The other electrical link is to the terminal block on the control. The green ground wire goes to the terminal that is marked "G." The two other wires (L T) connect to terminals marked as T3, T1 and. The T1 as well as the T3 are connected together if you're using a heater which operates on a solely phase. Check that the connections are tightly pressed.
The protection of the overtemp heater is the last connection. It goes through the terminal block, which is then connected using one of the cage clamps. This connection requires similar preparation to the others, so refer to the label or images of original wire connections.
Thermostat
A thermostat is a digital gadget that monitors the temperature in its environment and can determine if the heater must be turned either on or off to ensure your desired indoor temperature. It's an easy concept but there's an array of various thermostat types that work differently.
There are two types of thermostats; mechanical and digital. Mechanical thermostats rely on a piece of metal, which expands or shrinks as it warms up or cools down. This allows it to switch an electric circuit connected to the heating system. It can also be switched on and off. Digital thermostats, however, are equipped with sensors inside that detect the temperature of the area and regulate the flow of electricity based upon that information, without the need to physically move any strip of metal.
The non-programmable (non-digital) thermostats feature a dial which allows you to set or alter the desired temperature. They tend to be less expensive than programmable thermostats, and might be more convenient in places in which the temperature doesn't change significantly from one season to the next.
It is possible to program (digital thermostats) to turn on or off your heater at certain intervals during the day and during specific days. They're a fantastic option to those who go out for work, run late or have children and need to have a comfortable bed to rest when they get in.
The data logging type is a little more advanced than the other thermostats. It helps find issues through monitoring temperature readings taken from different sensors located in your house. They may also give a historical records of how HVAC and cooling system has been utilized in your house.
If you're running a modern digital or smart thermostat that doesn't work, make sure that the batteries are still in good shape. Make sure that the fuse box or circuit breaker hasn't been overridden. If the thermostat is still not work after all the switches have been turned on, then you should contact an electrician. Perhaps it's time for a reset. The system may need a reset.
