The mechanical contractors are responsible for the installation & configuration, customization, repair and the maintenance of the plumbing, heating, cabling, piping, ducting, and HVAC controlling systems. They can work from the stage of planning and designing to the commissioning and maintaining the systems in an efficient and productive manner. They can take up projects in the residential, commercial, and industrial fields to deliver consistent quality output. From the perspective of the discussion here, they are the in floor heating specialists for the installation of the radiant heating networks.

The in floor heating system requires the plumbing works in several stages. The primary tasks are related to the piping near the boiler. It involves the installation of the boiler, connecting the municipal water supply pipes to the inlet, installation and configuration of zonal valves, pumps, return pipes, and the connectors and joints within the piping network.
The in floor heating systems require the installation of a large storage tank for the hot water from the boiler. Most of the modern systems have an inbuilt tank which connects to the boiler. Installation and configuration of the tank and the connecting pipelines is another important task of the mechanical contractors.
The mechanical contractors can install the loop circulators within the in floor heating network. They can route the piping from the boiler through these systems into the radiant panels. They are useful for maintaining the constant water pressure, as it flows from the ground/basement across the horizontal and vertical pipelines.
The formation of the piping layout requires the excavation works for the new house flooring. The mechanical contractor takes care of this task. For the existing floor, they can install the insulation layer on the existing floor. The layout of the PEX pipes comes over this layer, followed by the covering of the panels with one more layer of the flooring. It could be the same as the base flooring or different, depending on the foot traffic and other forms of static and dynamic load.
The mechanical contractors can install and configure the radiant pipelines within every room in your home. The can perform this task for new homes before the flooring installation. They can also install the pipe and panels over an existing concrete, panel, tile, or stone floor. They ensure the design to keep the temperature difference between hot water supplies and return pipes to be the minimum possible value.
They can install the radiant pipelines in multiple forms and patterns. Their aim is to reduce the structural heat loss to the near-zero values.
Perimeter spacing calculation is one of the key services offered by the mechanical contractors. They perform this task before laying out the pipelines within the radiant heating in the rooms. The calculation depends on number of parameters like the distance from the boiler, elevation level, flow loss, pressure loss, required heating efficiency, etc.
An efficient mechanical contractor can place the supply tube and the return tube within the closest proximity for preventing the heat loss. Since the temperature at the surface will almost remain same for both the pipes, the even floor heating is made possible without having to install the pipes at too much of distance between them.
Finishing the top floor covering is the decisive task of the mechanical contractor. He is responsible for the selection of the right material at the top cover. They consider the heat transfer from the piping to the floor surface. They can select the material with the optimum R-Value for transmitting the maximum possible heat.
The mechanical contractor can install the heating control mechanism within the radiant panels, as well as the boiler systems. In both eh cases, they consider the average fuel consumption in the long run. They can calculate the parameters like the material strength, ply thickness, size and weight of the flooring to be installed over the radiant heating system.
The mechanical contractors can perform the task of installing the radiant piping systems within the existing hard floor or the plywood floors without disturbing the top layer. They do it when the homeowners don’t wish to dig or cover up the existing wooden flooring. For achieving this, the contractors may have to do the plumbing works from outside the room perimeter, drilling holes through the floor bottom layer and passing the tubes.
The mechanical contractors in your region can also install and configure the pressure and flow control valves from the boiler pipes to the radiant piping networks. The pressure boosting valves push the water to the top floors when the distance between the boiler and the destination PEX panel increases.
The mechanical contractor can install the complete electrical cabling and paneling systems for the boiler and the radiant heating systems. The switches at the panel rooms can turn on/off the heating as required. The cabling at the boiler network connects the device to the main supplies and the control panel.
If the boiler is fired by gas or oil, the mechanical contractor can install the fuel pipelines between the boilers and the gas tank. He can install the tank within a safe enclosure and configure the protective structure for safety from fire, flooding, moisture, snow and other environmental elements.
A licensed mechanical contractor can clear the HVAC, plumbing, water supply and the other legal permissions from the local government authorities whenever required. He can also clear the EPA certifications when the in floor heating systems are being installed at the large residential apartments or commercial buildings.
The mechanical contractor can arrange the material supplies required for the installation and configuration of the in floor heating systems. Since they have contacts with the manufacturers and wholesalers, the cost procurement will be considerably lower compared to the retailing costs. Hence, you can save more than 40% of the material costs. The other benefit is the supply at your doorstep without having to take the trouble of searching.
