Gutter Heating

To better protect your property

Winter time is considered as one of the most charming and pleasant time of the year, however it can also be a huge trouble maker, full of unpleasant surprises. 

No matter how well the roofs and gutter systems were constructed, they may not always be able to deal with winter weather conditions, what in fact can lead to serious damages caused by snow and ice.

More information

Strong emission of sunlight during winter months, can make snow and ice melt. Refreezing meltwater in gutters or spouts may result in dangerous icicles or roof overhangs. This process can also easily become a reason of blocking and destroying the drainage facilities and in fact be dangerous for building construction.

DEFROMAT Gutter Heating Systems can be installed in nearly every drainage system. By heating the crucial areas, they provide the potency of gutters and spouts, eliminate the risk of accidents, prolong the life of drainage facilities and at the same time, increase the value of the property.

Almost 50 years of experience have made the DEFORMAT the leading supplier of heating tapes and cables with increased UV protection, controlled temperature and humidity sensors as well as  additional, essential accessories. 

After submitting construction plans or sketches, DEFROMAT can quickly create a corresponding cost offer.

Right performance  - right  regulation  - climate friendly,  because it is electric.

In the semicircular or box gutter, single heating conductor loops or self regulating heating tape can be installed in distance up to 20cm. Wider spouts, roof valleys and gutters required repeated placement of the heating tapes or capacity of approximately 200W/m2. As the heating power is only required in case snow or meltwater, to ensure the best functionality, it is crucial to install  temperature and humidity-depend control devices.

Installation and connection must be carried out or confirmed and guaranteed by an authorized electrician. 

DEFROMAT´s experienced assembly department will be happy to assist you with all engineering projects. In case you have any more questions, please do not hesitate to contact us.

  • Prevent spouts, gutters, roofs and building construction  from damages caused by accumulated snow, ice, meltwater and snow avalanches.
  • Prevent the formation of icicles 
  • Increase the value of the property

Roof Heating

Accumulated snow can be a reason of dangerous roof-avalanches. Mechanical snow removal, often causes damages to the roof structure, lightening protection system or other roof installations. Removing the snow from the roofs by professionals can generate huge additional costs.

More information

Electrical heating systems are so far the most effective way of protecting roofs from unfavorable winter conditions and can be installed on almost all type of roofs. They prevent icing and snow load occurring, protect roofs and facades from freezing rain and damages caused by melted water.

For the heating of roof surface ( roof overhangs or cold zones), we always recommend the use of DEFROMAT heating mats. 

The heating pipelines are fastened in a meandering pattern by plastic webs and tied off with cable ties. The heating mats themselves are fastened to a galvanized steel supporting cable or stainless steel cable. The cable on the other hand is fastened on the seam of the tin roof via standing seam clamps or on cable carriers to be mounted below the roof slab on the battens. 

Advantages of Roof Heating Systems 

  • Time saving 
  • Prevent roof from damages caused by mechanical snow and ice removing
  • Prevent roof and drainage system from damages caused by accumulated ice, snow, meltwater, snow avalanches.
  • Minimizes the risk of accidents caused by falling icicles or snow
  • Prevent roof from accumulating of the snow
  • Prevent the formation of icicles 
  • Increase the value of the property

Outdoor Heating

What is the best, is electric

Places like underground car parks, garages, ramps, pavements, bridges, external staircases, emergency exits or heliports in hospitals are known from their strict safety requirements. Especially during winter time it is necessary to keep the areas clean and dry. 

More information

There are many methods of snow and ice removing available on the market. Unfortunately sprinkle surfaces with chemicals or salt can cause corrosion, have negative impact on building construction and caused huge damages to the environment. Mechanical cleaning can be considered as the right one, but electric outdoor heating systems have proven to be a much more effective solution.  With the easy access to electric energy, special heating mats and/or heating cables, it is possible to warm up nearly every requested place, protect it from snow and ice and at the same time, reduce the risk of possible accidents.

Years of experience allow DEFROMAT to offer complete open space heating projects and overall heating installations. After providing sketches with requested heated area and specifying possible energy-feed-in points DEFORMAT can prepare for you an estimate cost offer or a tender text.

Detailed plan is important

To ensure the right functioning of electric heating systems, the electric energy must be constantly delivered.

It is assumed that, on average winter season, a connection power of 300W/m2 with operating time of 100-200 hours is required. That is why, we highly recommend to discuss the electricity delivery, with your electric energy supplier.

Pipe Heating

To keep it flowing...

For water supply systems, fire pipes, pipelines responsible for keeping the liquids at requested temperature or tanks dedicated to high viscosity fluids, it is crucial to protect them from low temperatures, frost or unfavorable weather conditions and/or to keep them at proper temperature point. For energy saving reasons and right performance, heated pipes and containers should be also thermally insulated. To achieve best protection, electric heating systems are currently the only practical and most economical technology.

More information

Water pipes or fluid pipes responsible for chemical, oil or substance transportation are nowadays a indispensable element of every building installation. Especially during the winter time, the unexpected interruption of fluids supply caused by temperatures below the freezing point, can be the reason of serious damages. Whenever the viscosity of transported fluids drops down, the right transportation can not be any longer guaranteed. 

Thanks to specially developed DEFROMAT pipe heating systems, all liquids can be heated up to the required temperature and constantly kept on requested temperature point. 

Installation can be done inside as well as outside of the pipeline. In case of an external heating tape installation, the heating tape can be easily attached with self adhesive bands. 

To ensures the most effective functionality and constant fluids transport, we highly recommend to use dedicated for pipe heating systems DEFROMAT's controller.

Heating cables - Heating tapes

Conventional heating cables in accordance with DIN VDE Standard and self-regulating heating tapes in various designs and capacities as well as complete range of control and monitoring devices are available at DEFROMAT. 

For further information and non-obligatory offer, please contact us directly. 

The right technology

The required heating capacity depends on the nominal pipe size, installation thickness and temperature difference between the pipe wall and surrounding area and it should be precisely calculated and dimensioned. 

Installation by DEFROMAT

The pipe heating installation should always be carried by a qualified electrician, pipeline constructor or insulator. However, for big and technically complicated projects and demanding construction we stay at your disposal, ready to advise and help.

Typical applications

Heating of the pipelines can be divided into following applications 

  • Frost protection dedicated for water lines
  • Temperature maintenance 
    (Compensation of heat loss during production, transport or only at standstill)
  • Heating liquids up to the required temperature 
    (Used for engineering processes, for oil or chemical transport )

Mainly heating according to DIN VDE 0253 and the so-called self-regulatory heating tapes have proven to be effective in practice as a heating elements for electrical trace heatings. The resistance value of heating pipelines according to DIN 0253 with a heating conductor made of high-quality resistance wires and a plastic insulation have to be precisely adjusted to the supply voltage for certain lengths and heating capacities. DEFROMAT has a wide range of resistances of such heating pipelines in silicone / PVC and Teflon in stock and determines the heating capacity. With those it is possible to cover most of the applications in housing technology.

Thanks to positive features,  the usage of self regulating heating tapes last years has significantly increased.

They can be flexibly used and because of self-limiting effect, adapted to the respective temperature. Protection against overheating and accuracy of cutting to length are further advantages.

Self-regulating heating tapes by DEFROMAT, are available in capacity range 10W/m to 60W/m. The self regulating effect makes it possible to design the thermo-technical system bit more generously.

Because of lower (comparing to self regulating heating tape) load capacity, to get a connection at feed point, conventional heating cable (DIN 0253) must be laid as a loop twice, parallel to the pipe. In case of self regulating tape, only parallel installation is required. 

Increasing of heating power can be achieved in both cases, by double or multiple, parallel lying or by winding.

The heating cables and self-regulating tapes, must be fastened by special adhesive tapes or aluminium tape at a distance of approx. 30 cm. before laying the insulation. Resignation from thermal is insulation is possible or useful only in certain cases.

Due to the fact that even self-regulatory heating tapes do not switch off, but only reduce their heating output, it is for the most applications recommended to have a temperature control and/ or limitation for reasons of economic efficiency. The temperature sensor is usually applied on the heated pipe in order to detect the actual conditions and the effect of the heating output. A control via the outside temperature is suitable only in special cases and only in special cases it is possible to dispense with a control (when hot water pipes are heated). 

The controller can be mounted on site as a surface- mounted version and can directly switch the heating output or may be accommodated in a control distribution together with the switchgear assemblies and protective gear.

Self regulating heating types:

A = KA 2X, 10 W/m at 5°C
B = KB 2X, 25 W/m at 5°C
- = not economical, choose stronger insulation or apply longer heating tape by winding
□ = required insulation strength according to the heating system ordinance

The exact dependance between the thermal engineering task and the required heating capacity for the given system specifications ( nominal pipe diameter, insulation thickness) are described in details in the DEFROMAT's  pipe heating system description.

Frost protection can be applied according to the table below.  Assumption: pipe holding temperature  +5°C, lowest ambient temperature -25°C, laid simply straight on the pipe.

Advantages from electric pipeline heating 

  • Prevent pipe lines from icing and freezing
  • Hold transmitted fluids on the desired temperature point 
  • Prevents fluids from changes in viscosity
  • Help fluids containing fat at the right pour point 
  • At low outdoor temperatures, outdoor heating systems prevent liquid temperature from dropping down, 
  • Deliver hot water regardless the atmospheric conditions
  • Allow to install underground pipelines 
  • Prevent pipelines from freezing, keeping liquids flowing 
  • Reduction of damages caused by broken fluid line, often associated with water damages

Other heating systems 


There is a variety of special heating cable applications in building technology as well as in trade and industry. They can be used indoor and out door, to keep houses warm and ramps free of snow and ice. Whenever there is a need to keep liquids at the right temperature . warm them up or keep them in proper viscosity, electric heating installation can be apply.
