Selection of pipes for floor heating

Warm water floor - a convenient and inexpensive way to heat your home or apartment.The most reliable and economical warm water floor, connected to the heating system or individual heating circuits powered boiler.Costs in the performance of this floor is quite justified, because in the process of exploitation, they pay for themselves very quickly.At the same time a significant part of the cost is the cost of the pipe to perform primary circuit.

Selection of pipes for floor heating

What better pipe for underfloor heating?It depends on several factors: the method of packing, loop length, manner of implementation and screed finish.There are several types of pipes used:

• Brass;
• PVC;
• pipes of cross-linked polyethylene.

They all have their own characteristics that must be considered when choosing.

Copper pipes

They are distinguished by high quality, excellent heat dissipation, strength and durability, but the maximum price of the options and some difficulties in the installation: Flexible pipes must be made from a template and used for welding joints.Moreover, if the floor heating konturteplogo connected to a heating system with radiators of aluminum or steel, may cause a galvanic couple, causing electrochemical corrosion radiators.

Copper pipes for floor heating

Copper pipes for floor heating is usually applied where needed most rapid heating facilities with minimal heat loss.This is true for houses, which in view of the impossibility of installing a gas boiler coolant get more expensive way: by diesel or electric boiler.The costs of copper tubing is 5-7 times higher than for plastic or metal and plastic.In this case the flow temperature for copper pipes can be maintained at 5-10 degrees less than that would eventually lead to their payback in two to three years.

for floor heating use copper pipes 20 mm in diameter, trying to make the minimum number of joints.Because of the high temperature heat in the initial part of the circuit can be significantly higher than at the end, which is why the floor warms unevenly in different zones.Therefore preferable to lay copper pipes "snail" or "double-snake", that took place next to both direct and reverse part of the circuit.

Metal pipes

Metal pipes are composed of heat-resistant plastic, reinforced with solid or mesh metal layer.Their internal surface is smooth, it is not formed on the deposits, allowing you to keep a constant working clearance for the entire service life.For underfloor heating pipes must be chosen, designed specifically for the hot coolant.

Metal pipes for floor heating - the easiest option for self-assembly.Attaching the heating circuit to the forward and reverse collector made via compression fittings without special tools, besides the tube retain their shape during bending, and can be installed by one person.Thus plastic pipes have two major drawbacks:

• fittings during operation require periodic tightening, so you need to ensure unhindered access to them;
• when the ties need to take care not to crush the pipe and not to narrow their gap.

Heat transfer from metal pipes is slightly lower than umednyh, but this is offset by their low cost and ease of installation.It is most convenient to mount the plastic pipes on the special insulating base mat - they are simply placed in the spaces between the lugs, creating the desired contour, and on top of poured concrete floor.With this method of stacking the probability of damage is minimized.

When choosing a plastic pipes manufacturer is better to prefer proven firms themselves and choose the pipe with oxygen-barrier layer - it will prolong the life of the steel heating water.The diameter of pipes for heating water - 20 mm.

Polyethylene pipes

One of the most popular types of performance involves the use of underfloor heating pipes made of polyethylene threaded.These pipes are the most cheap, easy to install, have resilience and are not afraid of crushing when the screed.Heat transfer from the polyethylene is lower than that of copper or plastic pipes, with a single layer structure has high reliability.Also worth a stop to them their choice when used as a coolant antifreeze - polyethylene has a very high resistance to aggressive liquids.Another advantage of plastic pipes is the minimum bending radius that allows you to outline any form without the formation of areas with a voltage of the material.
