Why Powerflush the system before fitting a new boiler ?
“We can’t believe that not every installer offers Powerflushing when fitting new boilers”!
WHY?
1. A quieter boiler results from the removal of lime scale build up in the system, this is commonly called “Kettling”.
2. Hotter Radiators and a quicker warm up from the removal of Black Sludge “Magnetite” cold spots and Hydrogen build up produced by corrosion within the system.
3. A longer lasting system, pumps will last longer and radiators will have an extended life if there is no corrosion present and suitable corrosion inhibitors are used.
4. Lower fuel bills due to a more efficient system, costs more to heat solid magnetite than it does water! It is estimated that up to 25% saving can be made on your fuel bills compared to a heavily clogged system.
5. Helps to comply with The Benchmark Code of Practice, manufacturers warranties and Building regulations Part L, BSI 7953 when installing new boilers on old or new installations.
What do we do when we power flush?
Put simply, we couple up a specially designed powerful pump to the heating system and with the help of specialist chemicals, blast the debris out of the system, radiator by radiator.
The power flushing process will cure most circulation problems, but cannot undo the corrosion and gradual decay of heating system components that has led to the need to power flush the system. Note that we always check for signs of corrosion before and after the process.
Occasionally some systems may have radiators with localised deep corrosion pits, with only a scab of rust preventing the system water from leaking out. The vigorous flow rate required to mobilise sludge and deposits may dislodge such a scab, leading to a leak from the radiator during the flushing process. The advanced stage of corrosion required for such a situation means that the leak would occur imminently even without a powerflush. If it should be brought forward slightly by the flushing process, then it is better that it occurs whilst a heating engineer is present to remedy the problem, rather than for it to arise over a weekend or whilst the house is unoccupied.
Remember to check that your installer has included POWERFLUSHING in their estimate. (or ask us if not!)
As well as power flushing before new installations, Hometech of Harrogate offer powerflushing services on older boilers to potentially cure noise, poor flow, cold radiators etc… in Harrogate, Knaresborough, Ripon and Wetherby. Contact Us for more details
