Tankless Water Heater – Installation Advisory
As a rule, the installation of the tankless water heater is not a DIY proposition. This task has a number of prerequisites which need to be looked into carefully. This often requires the expertise of a professional. Besides, faulty or unprofessional installation of your tankless water heater will void the warranty.
Basic conditions required for the installation of an electric tankless water heater
The electric water heater is a heavy-duty appliance. When you plan to install a tankless water heater, the very first consideration should be whether the existing electric connection in your house will be able to accommodate the device.
It is better to install a three-phase electric connection before you install the electric tankless water heater. The electric connection need to have high amperage in order to have the capacity to feed the water heater.
The wire used for electrical connection should be of the correct size. Similarly, the diameter of the vent pipe also should suit the model you are using. These factors necessitate the hire of a professional electrician and plumber. Solid copper wire is strongly recommended.
Installation of the tankless water heater
Care should be taken to follow all the local codes that govern the installation of the water heater and acquisition of the suitable electrical connection. This will save you from a lot of official snags
Selection of the location of the water heater should be done carefully. It should be sufficiently off the ground. The unit should be installed leaving at least 18 inches of free space on all sides. This will come in handy when there is a need for repair or replacement. This is the service space that will facilitate easy servicing of the device.
Installing the water heater on the outer wall will help in plumbing for the vent. Outdoor installation of the tankless water heater also helps in the same.
The tankless water heater is not as heavy as the storage model. Still care should be taken to see that the unit is mounted on a wall or stand which will support it adequately.
Plumbing for exhaust vents is also governed by certain codes. The vent should be fixed in such a way that it does not release the exhaust into the neighboring house or building. The sound of the vent should not be a public nuisance.
The hard water does not harm the tankless water heater much. However, if the local water is extremely hard, it is better to install a water softener. This will increase the longevity of the unit and will not need frequent servicing.
Checking for possible malfunctioning in the electrical connection
It is imperative that the electrical connections to the tankless water heater are flawless. Any glitch in it will be detrimental to your water heater and the electrical system of the whole house. So after installing the tankless water heater, you have to conduct a series of simple stress tests to see that everything is intact.
The sockets and switches should have cover plates to shield any possible sparks. Switch on the heater and place the palm of your hand on these shields to see if they grow extraordinarily warm. If so, connections inside should be checked for any loose contact.
The same stress test should be conducted in the case of circuit breakers and service panel also. If any anomaly is detected, switch off the heater immediately and make sure that the wires and other parts used in the connection are adequate for the model. The manual or the label on the unit will provide the needed information.
If all the stipulations in the installation manual are followed implicitly, you can be sure of hassle-free hot water consumption; what’s more, you will need servicing your unit less frequently and your best tankless water heater will enjoy a long life.
