Composition of equipment and documentation of the roof drainage heating system
Composition of equipment and documentation of the roof drainage heating system
Very often, people who want to install a roof drainage heating system ask about the cost of the system. Basically, the questions boil down to the cost per linear metre of gutter or downpipe. Assuming that this information will help to independently calculate the cost, the customer is mistaken. In fact, everything is a little more complicated.
It is not only the lengths of pipes and gutters that need to be known in order to select the necessary components. The best option is for the customer to provide a drawing of the building and roof with the specified dimensions. It is also necessary to understand where exactly the system can be powered, i.e. the location of the control cabinet. This information will be sufficient for a preliminary cost calculation.
The cost of a “standard” roof drainage heating system consists of the following components:
- Heating cable
- Fasteners for cable laying in gutters
- Wire rope for securing cables in pipes
- Terminal boxes or connection sockets
- Power and control cables
- Routing system for power and control cables
- Controller with sensors
- Heating system control cabinet
- Also, we shouldn’t forget that someone has to put it all together into a coherent whole
Every roof has its own structure, it is not only trays and pipes, the configuration of the roof is completed by valleys, rolls, joints. In some cases, heating trays and pipes is not enough. There is a need to heat the edge of the roof, valleys, and all sorts of problem areas. When selecting the equipment for heating the drainage system, it is necessary to take into account the angles, lengths and the roof covering.
Drainage pipes can be installed externally, internally or mixed. If the drainage pipes are installed inside the building, it is necessary to consider whether the building is heated or not. Mixed drainage pipe installation systems may require a change of heating cable from resistive to self-regulating.
There are a lot of questions. It is not only the heating and drainage system that depends on the correct selection of equipment and system design, but also on how long and efficiently it will work. The service life of the façade and the building itself depends on a correctly installed heating system. The cost of making a mistake will be quite high, you should never rush and make hasty decisions.
If the building is quite complex, it is not possible to make a final decision on what to heat, which heating cable to use and which control system is required without inspecting it. If it is a building under construction, a project will be required.
Regardless of the complexity of the heating system, ask the contractor for a preliminary layout plan of the heating cable, as well as power cable layouts with terminal box locations. Visualisation will help you to understand and see exactly what you will end up with.
It is essential to agree in advance with the contractor what documentation you will receive after the system is installed. At the very least, it should be a system passport. The passport should clearly indicate which heating sections are laid in which lengths in certain places. Power cable laying diagram with cross-section and number of conductors. Electrical diagram of the control cabinet, diagram showing where the sensors are installed. Detailed operating instructions for the heating system. Ask the contractor for a sample of the passport you will receive as a result.
The documentation you receive from the contractor will allow you to understand exactly what you have been sold, and in the event of a system failure, to make a quick repair.
