Liverpool Boiler And Radiator Power Flushing Services

With over 40 years experience in the field of domestic Boiler Power Flushing, Merseyside Central Heating Can dramatically improve the performance of boilers in your home to help maintain the efficiency of central heating systems and to ensure their long term protection against the damaging effects of corrosion and limescale.

Dramatically Improving Performance of Boilers & Radiators With Our Full Power Flush System

As the original manufacturer of the very first powerflushing unit the squid – in 1987 Fernox have continually invested in research and development and have recently launched the new Powerflow Flushing Machine. With all the latest design features the Fernox Powerflow Flushing Machine will ensure a fast and effective system clean.

Powerflushing - The Cleaning & Treating of Central Heating Systems

All new systems should be pre-commission cleansed in accordance with BS:7593 and Benchmark. This ensures flux residues, excess jointing compounds, mineral oil and other contaminants that can be found in the system following installation, and that can effect the performance of the system or cause component failure, are removed. It is important when installing new boilers into old systems that all sludge is first removed from the system or this could accumulate in the new boiler and lead to premature failure. Additionally, In hard water areas existing systems will have accumulated limescale together with corrosion deposits in the heat exchanger, which could easily have reduced the boiler efficiency by over 5%.

We base ourselves on Fast, friendly reliable service with most of our work coming from recommendations and word of mouth.

    - Fuel Wastage

    Without treatment, corrosion debris will accumulate in the boiler causing increasing limescale deposits, reduced heat transfer and up to a third of a fuel bill going to complete waste.

    - Boiler Noise

    This increases in frequency and intensity as deposits of sludge and scale build up in an unprotected boiler.

    - Cold Spots

    The familiar cool low central area of a radiator indicates a build-up of black sludge sediment that restricts flow and reduces heat.

    - Frequent Venting

    When the top of a radiator is cold during operation, either air or hydrogen is to blame. Hydrogen gas builds up as a by-product of electrolytic corrosion and is flammable (due caution is required).

    - Pump Seizure and Failure

    The abrasive and magnetic properties of black oxide sludge increase shaft and bearing wear in pumps causing them to stick or fail.

    - The Solution

    Pre-commission cleanse new systems and thoroughly cleanse existing systems with Fernox Cleaner or Fernox DS-40 System Cleaner before adding a suitable Fernox Protector to maintain efficiency and ensure the longevity of the system.

Boiler Repair Frequently Asked Questions

Boiler will need to be filled up with water via the filling loop until the pressure reaches 1-1.5 bar. Most recent combi's boilers will self-reset when the pressure is back to normal. If not then press and hold reset for 3-4 seconds.
Check that the room thermostat is turned up and the programmer is calling for heat. If so then normally one of the two is broken, If you have a wireless version then replace the two AA batteries.
This is normally caused by a faulty diverted valve located inside the combi boiler, this requires an engineer visit, we can call out to fix this at a labour cost of ÂŁ55 plus Vat plus the cost of a new diverter valve.
The most common reason for this is a faulty expansion vessel, normally when the heating is turned on the pressure will shoot up to 3 bar on the pressure gauge and the system water will expel through the small 15mm copper pipe outside, if this is the case then we can which re-charge your expansion vessel within a 1 hour call out. Other reasons for pressure loss are there is a leak somewhere on your system.
Could be one of many parts on the boiler and will require an engineer visit, most common leaks are due to faulty automatic air vents. Fill in attached form for a quotation.

Conventional System Faults Frequently Asked Questions

Will most probably be a faulty 2 port/3 port valve or a pump (if system works on gravity hot water) fill in attached form for a quotation.
Check that the room thermostat is turned up and the programmer is calling for heat. If so then normally one of the two is broken, If you have a wireless version then replace the two AA batteries.
Same again a 2 port or 3 port valve depending on what set up you have.
This is normally an issue with a broken boiler thermostat or more likely a blocked heat exchanger, this can rectified by power flushing the system or chemically cleansing/flushing the system, contact us for price and advice.
This will be either a new Thermocouple or a gas valve, this needs an engineer visit, Click here to request a free quote.
If your boiler is a condensing model then most likely the condensate pipe is frozen, if the pipe is accessible then try boiling a kettle and pouring it over the plastic pipe to try and thaw it out.
Normally means your 2 port or 3 port valve is passing, could rarely be faulty programmer.

Radiator Faults Frequently Asked Questions

The radiator requires bleeding (please note the boiler has to be re-pressurised once complete)
Your radiators need either to be power flushed or the system chemically cleansed.
Most common cause is a faulty Thermostatic radiator valve. If no thermostatic valve is on the radiator then it could be air locked. Try turning off all the other radiators on the system to push the air through the problematic radiator.
