Often the question arises whether it makes sense to insulate pipes later. This question is answered quickly, when it comes to avoid condensation. This energy is not only wasted, but also money. The subsequent isolation and optimization of hot water pipes helps to sustainably conserve energy and thus money.
If warm water is not flowing through or poorly insulated pipes, extreme energy is consumed. Add to this that in various environment variables condensation can occur. This has a noticeable effect on the wallet.

Various calculations with ISOWTC have shown that even with a good renovation of older insulation very quickly. So it may be that the amortization period set after 1-2 years.
It also provides the legislature this: Since 2007, heating pipes and hot water pipes must be insulated from the Energy Saving Ordinance if they lead accessible through unheated spaces. The financial cost, and thus affiliated installation costs are very low. The Energy Saving Ordinance (Energy Conservation) describes here the standard that is required. It is expected that this standard not only for commercial units is valid, but also in the foreseeable future relates to each residential unit. However, after the energy saving is very high, and therefore your money is well spent, but this is in your best interest.

Suitable materials for this purpose are pipe sections or tubes made of synthetic rubber or polyethylene. These are available in various designs. Part, these are provided with a slot, so that the assembly is very simple. Various hoses are also self-adhesive, in order to achieve an optimal result. Thus, your insulation is diffusion-tight and provides complete protection with adequate insulation thickness. The insulation thickness can be obtained from your dealer. Likewise Fachläute can calculate the optimum with different programs and economic insulation thickness. The leading program for this is ISOWTC and is a thermal design available online.

The thermal properties of synthetic rubber and polyethylene are very similar. The decision is mostly in the use of time and money. Basically, a “cheaper “insulation usually requires a greater insulation thickness, but this again increases the price. It is best to consult with a specialist. Here you are also tested products. Often, “Import insulation” is not even worth half the money.

The commonly used products are “Armaflex “, ” Kailfex ” and “K -Flex”. All these products have certifications and VDI are quality controlled. The quality check is performed according to the principles of the VDI ‘s and is as from the Research Institute of Thermal Engineering .

I wish you much fun while saving energy and money.
