Cleaning of heating and cooling systems

TermoRens has extensive experience in cleaning all types of pipe systems. This is a neglected area that inflicts high costs on building owners in the form of lost heat / cold transfer, corrosion of materials in the form of oxidation and loss of flow in drinking water systems. This results in to low pressure with annoying little tap water. More frequent replacement of boilers, heat pumps and pipes. In water pipes, biofilm is also formed where bacteria develop and have the best condition. A thick coating of oxides and humus settles in the bottom of boilers  can result in a legionella outbreak. Coatings in pipes also mean that water-borne underfloor heating system loses its effect and that heat pumps are unable to deliver the energy for which they are dimensioned.

All these problems can be easily solved with the Termorens cleaning fluid. Simply explained, the TermoRens concentrate is dosed into the plant. This mixes with the water in the plant and starts immediately to breaks down all types of scale. Rust, limestone, humus etc breaks down completely and back into liquid form and can then be flushed out of the plant when the cleaning process is done. Normally, a cleaning process takes one day before the flushing of the plant start. The proses is ready when you have the same water quality out from from the plant as you put in for flushing,

Termorens cleaning liquid is dosed into the plant with 10 – 20% of the plant’s volume. The degree of growth and the age and history of the plant determine how much.

Normally, a cleaning process takes one day before starting the rinsing of the plant. The plant is rinsed until you have the same water quality from the plant that you use for rinsing,

How much Termorens Liquid ?

Use the thumbroul – 1 kw corresponds to 1 liter of Termorens concentrate.

In a average house, there is often a 30 kW boiler and then you use 30 liters of Termorens concentrate. Smaller blockhouses often have a 300 kw boiler and then you use 300 liters of concentrate, etc. We have cleaned plants where we have used 50,000 liters of concentrate in one and the same operation.

New systems have smaller dimensions both in pipe dimensions and equipment such as radiators, heating batteries, etc. Old systems often have large rib radiators and larger pipe dimensions. In such plants, the consumption of cleaning liquid is multiplied by 1.5. An old plant with rib radiators and a boiler of 300 kw then needs 450 liters of concentrate and not 300 liters.

What about leaks?

Many people have bad experience with “acid washing” of plants because many leaks occur. Termorens cleaning fluid is added a special inhibitor which means that it only removes coatings and does not attack any material in the system such as steel pipes, copper pipes, stainless steel pipes, gaskets etc. If rust and paint or other coating should hold back a leak, this will be detected by a leak. It  had come sooner or later anyway. Now it comes when there are people present and will not do big damage to the building. It can therefore be said that by cleaning, you also get a control of the pipe system and got this to be repaired. Leaks are not a big problem. This has saved many projects from replacing all the old pipes, but rather cleaning and using both pipes and equipment further.

What can be cleaned?

All components with water flow can be cleaned. All types of pipes. Underfloor heating systems. Heating system. Cooling system. Sidewalk heating. Geothermal heating systems, Heat exchangers. Heating and cooling batteries. All types of water heaters. Heating coils in old water heaters. Radiators both in houses, in cars and on boats. Cooling systems in cars and boats. Vacuum drainage systems in houses. and on vessels. Water tanks. Plastic screwdrivers, Cooling on production equipment. Evaporators.

Termorens cleaning fluid removes Legionella bacteria and other bacteria quickly and effectively

Termorens cleaning fluid is environmentally friendly, biodegradable and can be poured into drains after use. It is simple and effective to work with.

Termorens cleaning fluid is produced in our factory in Skien, Norway and is always in our warehouse.

Clean the pipes before switching from oil boiler to heat pump

Source: Article from Hus og Bolig

HEATING: If you are considering replacing the oil boiler with a heat pump, you should make sure that the pipes in the floor are clean and neat.

– Not everyone is aware of it, but the pipes in waterborne plants will over time grow back if you do not implement measures to prevent this from happening, says Lance Chr. Horner in Vaillant Norway. The metals in the various connections in the system will eventually begin to corrode, and in the long run a sludge coating may form which settles in the pipes. In most cases, this will not present serious problems, but many will notice that they constantly have to turn up the effect on the heat source to achieve the same temperature as before.

– More and more people call us and say they are struggling to raise the temperature in their waterborne system. Very often it is due to sludge formation in the pipes. The sludge creates an insulating layer that prevents the heat from escaping. To get the same effect as before, you will have to increase the temperature, explains Rune Pedersen, technical product manager at Vaillant Norway.

Worse with heat pump

Even though it is not very energy-efficient to just turn up the heat, according to Pedersen, it will be possible to live a long time with such a solution. Apart from the fact that the cost of heating will increase, you will probably not notice it anymore. At least as long as the plant is operated by an old oil boiler. If you choose to replace it with a heat pump for environmental or economic reasons, the problem can immediately get worse.

– Replacing the oil burner with a heat pump, for example to operate an existing radiator system, has become very popular. The problem with this is that there is often a lot of corrosion and sludge in the old pipes. As long as this erupts and runs in an oil burner, it is not necessarily a big problem operationally, but if you install a heat pump, you can in a short time risk that the entire system stops, says Pedersen.

All heat pumps have a so-called heat exchanger. It consists of thin, fine slats or ribs. These provide heat to the water that passes through the plant. When sludge and other impurities come in contact with this fine mechanics, the pump will initially have problems emitting the heat it produces, and eventually stop working.
