Protecting ErP Performance: Adey explains

guest-blogger-series

This week our guest blogger is John Vaughan, Managing Director at ADEY Professional Heating Solutions, who explains the importance of water treatment in protecting ErP performance.

Magnetic filtration and water treatment might not be labelled under the Energy-related Products (ErP) Directive, but they will be crucial to the ongoing success of the scheme and delivering the savings expected in the long-term.

Safeguard energy ratings

Currently, around 30% of the carbon emissions produced in this country come from the domestic sector and it’s estimated that household heating accounts for more than 60% of domestic energy use. According to the Energy Saving Trust, boilers also account for around 55% of what we spend in a year on household energy bills.

By specifying binding minimum energy efficiency standards, the EU predicts that the introduction of the ErP Directive will bring a reduction in energy usage of around 20% in new buildings, leading to significant environmental savings and energy cost reductions.

However, the energy rating and savings potential given to an ErP-certified boiler at the manufacturing stage or on installation is more than likely based on its operation at peak performance. Yet if the heating system is not properly maintained and protected, its performance may start to deteriorate, preventing it from living up to its official energy efficiency rating. For example, research shows that the presence of just 5kg of sludge within the system, which is not uncommon, reduces radiator heat output by up to 36%.

Protective maintenance

For products labelled under ErP to deliver ongoing energy efficiency savings, installers need to ensure that every boiler installation is supported with ongoing protective system maintenance. To help installers deliver maximum results and protect energy efficiency ratings for the long-term, we recommend following our four-step best practice approach which has been recognised by two industry awards:

  • Clean – Introduce a good quality chemical cleaner to the heating system
  • Flush – Thoroughly flush the system to remove sludge and debris
  • Maintain – Install an effective magnetic filter to prevent sludge build-up – Service annually in line with annual boiler service
  • Protect – Dose the system with a good chemical protector and top up annually

Best practice ensures a heating system is protected from the damaging effects of black iron oxide sludge and corrosion, but it can also bring additional savings for homeowners.

Where our best practice approach is employed using proven effective filters and high-quality chemicals, we estimate savings of up to 15% on individual annual household heating bills, which could amount to a saving of £150–£170 a year for the average three bedroom property. Furthermore, the Energy Saving Trust (EST) estimates that using a premium chemical inhibitor can prevent up to a 15% reduction in the effectiveness of radiators.

At ADEY, we’ve long encouraged installers to have conversations with homeowners about the importance of regular, planned maintenance, the savings it can bring and the consequences of doing nothing. We believe the introduction of the ErP Directive is a great opportunity to start this discussion with a householder.
