Instructions for installation

1) Installation of PYD®

system pipe2) Connection to PYD® heating circuit distributor

3) Pressure test to control the leak tightness of the system

Laying of PYD® system pipe onto the grid of steel rods already installed. The pipe is fastened by means of the PYD® cable ties

Connection to PYD® heating circuit distri-butor with pipe guiding bows

The pressure test to control the leak tightness of the system is conducted with a pressure of 3 bar. This pressure has to be maintained until the installation of the concrete has been completed, in order to detect leaks immediately

Duration of assembly:

In order to install the system in an area of 400 m², 2 fi tters and 1 helper will need approximately one day, in case the subground has been prepared appropriately. This time specifi cation includes rolling out the PYD® system pipe, affi xing the pipe by means of PYD® cable ties, and the connection of the pipe to the PYD® heating circuit distributor.Setting up the PYD® heating circuit distributor and distribution box is estimated to take about 30 minutes.

PYD®-INDUSTRIE the ideal, effi cient solution to heating open spaces

is a practical and economic solution for heating industrial halls, warehouses, assembly shops, and workshops. Installation of our system doesn’t have any infl uence on the building’s statics. The entire surface area of the fl oor is used best for heating. Heat is given off into the room where it is needed: On the fl oor. PYD®-INDUSTRIE provides a maximum of comfort while being economic

An easy set up of the system guarantees high security in planning for the planner and easy installation for the fi rm.

Even distribution of heat, constant room temperature, small air circulation and minimal transportation of dust, particles, and particulate that can be produced from the production of goods create a comfortable room ambient. Nothing opposes operation with renewable sources of energy, like heat pumps. A low operating temperature of the system makes the use of waste heat of machines or other sources of excess heat possible. PYD®-INDUSTRIE system is maintenance- free, its longlife is ensured by the usage of optimized equipment. This is a great advantage for the investor and the company that runs the plant.

Stratifi cation of temperatures in halls and tall rooms

Since the entire surface area is used for giving off heat in PYD®-INDUSTRIE system, the system can be operated with low temperatures of the heating water. Practical experience has shown that temperatures above 30°C are seldom needed to operate the system. Distribution of heat onto the fl oor creates comfort. Not rarely, the inside temperature of the halls can be lowered by 2 K in comparison to conventional heating systems. The temperature perceived remains the same, though. Heat is given off where it is needed, room temperature lowers with increasing height of the hall, cold working and business areas are not an issue anymore.

Regulations for heat insulation for buildings with low internal temperatures.

Industrial halls or premises respectively are considered as buildings with low internal temperatures. Regulations for the heat insulation for this type of building are administered by the regulations for the conservation of energy (Building application after february 1st 2002).

Excerpt from EnEV§1 „Field of application“Except for §11 EnEV does not apply to:

– Premises that are mainly used for upringing and animal husbandry– Premises that have to be extensive and kept open for long periods of time according to their intended use – Underground premises– Under- glass premises and growing roomsfor raising, reproduction and sale of plants– Carrier air halls, tents and all other buildings that are intended to be set up and taken down repeatedly

§2 „Defi nition“Buldings that are heated to an inside temperature of >12°C and <19°C according to their purpose, and not heated more than four months annualy.

§4 „Buildings with low internal temperatures“In buildings with low internal temperatures the loss of transmission heat, that is to be specifi ed according to appendix 2 No.2 and to be related to the heat transmitting embracing surface, may not surpass the upper limiting values in appendix 2 No. 1.

§6 „Minimum heat insulation“/ DIN 4108-2 Parts of the building in premises to be erected that are in direct contact with the outside air, the soil, or parts of the building with signifi cantly lower inside temperatures are, according to paragraph 6 of EnEV, to be constructed in such a manner that the regulations of the minimum heat insulation are obeyed in accordance with the acknowledged rules of technology.

§17 „Exemptions“The appropriate authorities designated in the state law can issue an exemption from the demands of this regulation upon applicati-on. This is only applicable when, due to extraordinary circumstances in singular cases, the demands of the regulation would cause inopportune efforts or cause an unreasonable hardship. An unreasonable hardship is especially on hand when the required expenses within the common service life cannot be made up for by savings within an adequate period of time in demands on existing buil-

dings.

PYD®-INDUSTRIEregulations for insulation




Reasonable heat insulation for PYD®-INDUSTRIE

When the heating load for a building is determined in accordance with DIN EN 12831, the loss of heat to the ground will also be taken into account, according to DIN EN 12831. This loss of heat strongly depends upon the quality of the ground, the depth of groundwater, and other factors. The loss of heat also strongly depends upon the surface area, as the following calculation shows, and is defi ned by the method of calculation for different types of fl oor slabs as described in DIN ISO 13370.

A complete insulation of the concrete slabs doesn‘t always make sense, though. The insulation demanded by EnEV becomes less effi cient as the size of the hall increases and as a matter of that fact, useless. Thus, the case for unreasonable hardship in accordance with paragraph 17 of EnEV can be made, as a cost-benefi t calculation shows.

Edge insulation in halls is to be installed horizontally and vertically in accordance with ISO 13370 in order to cover the extent of the bottom slab. This type of reasonable heat insulation is applied already.

Figure 1: Reinforced insulation of the bases of the hall by means of vertical insulation.

Time required for amortization of insulations of halls

In accordance with paragraph 17 of EnEV, unreasonable hardship can justify omission of heat insulation in parts of the building in contact with the soil, when a calculation of amortization has been made. To do so, the cost of the insulation is compared to the possible savings. Generally, the outcome of the calculation is such that insulation can be omitted. A corresponding informal request should be fi led with the appropriate authorities, though.
