POWER FLUSHING or JET FLUSHING. The objective is to restore systems with circulation,and to reduce wear and tear on components within the the system and boiler especially high efficiency boilers. (caused by sludge and corrosion deposits) t Power flushing removes these deposits and the problems that they cause.

Power flushing, in conjunction with designed chemicals is also an excellent way to pre-commission and clean a new heating system, to remove excess flux, swarf and other debris, and the grease and oil used to prevent rusting of components before use.


It is practical to power flush a heating system immediately before fitting a new boiler to an existing system to flushing machineprevent possible future problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet shown themselves.

Existing debris is often mobilised by alterations to the system/piping and the increased efficiency of the new boiler, and may then be reduced, in extreme circumstances, failure of the boiler. The high efficiency and compactness of modern boilers, developed to minimise fuel costs and pollution, means that they are more susceptible to problems caused by debris in the system water.

Pictures below show signs corrosion. Radiators internally are starting to corrode, eventually the radiators start to pin hole. Magnetite and red rust causing damage to components.


Power flushing,cleansing of central heating systems

Technical Home Services are trained professionally . All boiler and heating installations are flushed to a high standard.

Possible Symptoms:-

  • Cold spots
  • Poor circulation
  • Noisy systems
  • System blockages
  • Expensive bills
  • Dirty system water or Contaminated system
  • Is your heating system showing signs of old age
  • Does it take ages to heat up
  • Are some radiators completely or partially cold
  • Do radiators need frequent bleeding
  • Strange and unpleasant noises come from the boiler
  • Repeated pump failures
  • Boiler overheating
  • Constant intermittent lock out
  • Premature wear of components

Any of these symptoms could indicate that the system has circulation and flow problems as a result of internal corrosion, scale and sludge formation.


We offer a co
ntrolled chemical cleaning service for most domestic wet central heating systems. A professional service that can chemically treat and flush clean deposits from your system, with minimal disturbance and disruption to the normal operation of the system, often without disconnecting the boiler or any radiators.

At the end of the flushing process, the system is full of water, and re-instatement of the system to normal operation takes only a short while also we protect the system when finished.

Magnetic Dirt Separator 

THSHeat recommends the central heating brass magnetic dirt separator.

The Dirt separator removes dirt particles from installation water. This is important, as even the smallest particles can still cause huge problems in an central heating boilers and installations. The dirt separator is much more effective and low-maintenance than a filter, as a filter becomes blocked, resulting in a large pressure drop. Moreover, replacing a filter often is a difficult job whereas draining the unit it only takes a few seconds. With this unit, malfunctions, wear and tear, and maintenance are proactively reduced.

Low Flow Resistance: The dirt separator has a very low and constant flow resistance. Furthermore, the dirt collected does not affect the the units operation. Comes with a drainage tap to remove the dirt, has a large dirt collection capacity this is cleaned out on the yearly service.

A completely universal unit suitable for vertical, horizontal or even diagonal installations. The unit delivers a simple and efficient way to remove all types of dirt, debris and sludge from central heating systems.

Features and Benefits:

  • Proven energy efficiency by BSRIA
  • Cleans in seconds with no need to remove the magnet or the unit from the sytem
  • Slim design constructed from robust brass
  • Combines the unique Spiro Tube
  • Removable High Power Magnet
  • Optimum filtration technology
  • Suitable for vertical, horizontal and even diagonal installations
  • Unique dual action removes both magnetic and non-magnetic dirt
  • Keeps heating systems running at their maximum efficiency
Central Heating Water Analysis
We undertake water analysis tests which enables users to make an immediate determination of the quality of water in a heating system, enabling us to understand the causes of problems and to select the appropriate treatment to prevent future system failures and call backs.We can indicate to customers whether a system has been properly pre-commission cleaned, if corrosion is either taking place or is likely to occur, whether the system should be power flushed and whether it has been treated with the correct level of corrosion inhibitor. If power flushing is required, analysis can confirm that all deposits and residues have been purged from a system.Wet central heating systems must be properly cleansed and treated with corrosion inhibitor in order to protect them from the otherwise inevitable decay as system metals trend back to their natural state.We advise and give solutions and present the customer with choices.
