Removing sludge from your Central Heating System

Sludge deposits can cause your central heating system to work inefficiently or worse still, stop working at all. The sludge is created over time as the metal within the radiators and pipework in a property, is corroded and reacts with the oxygen in the air. As a result a build up of thick black sludge is extremely common place in heating systems across the UK.

Sadly a lot of insurance companies won’t insure your combi boiler or central heating system against any damage caused by this build up. As one of the most common causes of boiler breakdown and system in the UK, there are a few ways to resolve this. However, if you want to avoid a full system flush, the most cost efficient way to remove the sludge from your boiler system is to use a filter.

One of the best products out there to do this is currently the Magnaclean whose mantra is “Prevention is Better Than the Cure

 

Magnaclean FilterHow does a Magnaclean work?

A Magnaclean is a filter that is fitted on the return pipework that leads to the central heating system.

The Magnaclean filter removes sludge deposits that are present in the water as it pumps through your system. Removing this sludge is beneficial for a number of reasons:

  1. Reducing fuel consumption
  2. Reducing system wear and tear
  3. Reducing boiler breakdowns and the hassle and hardship they cause.

These features combined mean the return on investment for a Magnaclean Filter is much faster than other energy efficiency/maintenance devices.

Sludge deposits are one of the most common causes of boiler breakdown and system wear and tear and Magnaclean works by removing this.

Why can fitting a Magnaclean Filter be beneficial?

There are many benefits to proactively fitting a Magnaclean to your system. Firstly, it is obviously a lot better to deal with potential irregularities in your central heating system before they escalate to something more serious. By cleaning your heating system, you can stop the build-up of sludge in your pipework and radiators before it stops these things working as they should do.

As the Magnaclean can capture the sludge deposits at a quicker rate than they are deposited in the system, the Magnaclean filter does a great job at maintaining your system. In the long term this can help your heating system to last 60-80% longer it would do otherwise.

 

Alternatives to A Magnaclean Filter…

A lot of large heating and plumbing companies will recommend a powerflush as the only way to deal with the build up of sludge in our heating system. The truth is that a powerflush would help, but it is costly and isn’t something that is typically covered in the cost of your monthly boiler & heating cover plans. You are therefore likely to have to pay a lot to have this service carried out by a qualified plumber or heating engineer.

You can be proactive and try and avoid this expense. Having a filter such as the Magnaclean, or alternatives such as the Sentinel Sludge Remover or the Fernox Central Heating Protector, can enable you to minimise the build up of sludge in your system, meaning you reduce the likelihood of being affected by performance issues going forward.

Yes they have!

Worcester Bosch, one of the most well-known manufacturers of heating products in the UK, have now launched their latest models of Gas Combination Boilers.

The names of their new boilers, which have been added to Worcester’s new ‘Greenstar Classic series’, are as follows:

Greenstar 29CDi Classic Combi Boiler
Greenstar 34CDi Classic Combi Boiler
Greenstar 38CDi Classic Combi Boiler


The full specifications, brochures and installation guides are available on the Direct Heating Supplies website. (see links above).

What’s more, these new boilers replace some of Worcester’s most popular boilers and offer improved specification and greater performance.

The table that follows shows the old model of Worcester boiler than have since been superseded by the new Greenstar classic range.

As well as developing boilers that are compatible with a natural gas source, Worcester have also developed an LPG version of their new boiler models. All of these Worcester gas Combi Boilers are available from Direct heating supplies for a great low price with next working day delivery inmost cases.

 

What are the New Features of the Greenstar Classic range?

The new 29CDi, 34CDi and 38CDi boilers are top of the range, using the latest technology advances to provide improved performance and increased efficiency. The boilers operate quietly and thanks to their stylish, modern design, won’t look out of place in any home or property.

 

Flow rate

The biggest area of improvement in the new Gas Combi Boiler range is in the flowrate.

The 29CDi, 34CDi and 38CDi models all have an impressive heating output of 30kW but on top of this they give you improved flow rates of 12.3, 14.3 and 16.4 litres per minute (at a 35 degree temperature rise) respectively.

 

Energy Efficiency

All the new boilers are rated as meeting the requirements of a SEDBUK band A-rating. This means that they are all high efficiency boilers. All 3 boiler types will operate at an efficiency level above 90.1%.

This will save you money long term, especially if you are upgrading to one of these non-condensing boilers from an older model of non-condensing boiler. In this scenario you could end up saving between 20-30% off your annual heating bill.

 

Boiler Warranty

All the new boilers are available with a standard Worcester 2 year warranty, so if anything were to go wrong you would be covered. On top of this you also get a 10 year guarantee on the primary heat exchanger and a 5 year anti-scale guarantee on domestic hot water heat exchanger (offers are subject to terms & conditions) when you purchase a 29CDi, 34CDi or 38CDi.

For those that want to buy a boiler this year, we recommend ordered sooner rather than later. The reason for this? At the moment if you get your boiler from Direct Heating Supplies you can benefit from an additional 3 years of warranty.

That’s 5 years cover from Worcester instead of the standard 2. Just get your boiler registered with Worcester before 31st December 2014 (terms & conditions apply).

 

One more thing….Changes to the name of the Greenstar 42CDi NG

As well as introducing 3 new boiler models into the market, it is also worth noting that Worcester are changing the name of the Greenstar 42CDi Natural Gas boiler to bring it into the Classic series. It is now known as the Greenstar 42CDi Classic Natural Gas Boiler.

The specifications of the Greenstar 42CDi Classic Natural Gas Boiler remain exactly the same as the Greenstar 42CDi Natural Gas model.
