A closer look at an ErP label

A closer look at an ErP label

The introduction of the Energy Related Products Directive, or ErP, means that all new heating systems will now come with a product and package label to give a clear rating of their energy efficiency. Its purpose is to make the efficiency of heating products easier to compare, helping homeowners and installers to make informed and eco-friendly decisions.

In this blog post we’re taking a closer look at an energy efficiency label for a system package. This type of label would be provided whenever a heat source such as a heat pump or boiler is paired with another add-on product, such as thermostats or solar thermal, to create what is known as a ‘package.

ErP label – an overview

 
You can see a breakdown of the different elements of the label on our annotated version below. Click on the image to enlarge:

ErP system label

Heat source efficiency

The top left box includes the energy efficiency rating(s) for the heat source. For a combi boiler you would see a rating for both heating and hot water. For a standard gas boiler or heat pump without a built-in water cylinder or instant hot water capability you would just see a rating for heating.

System heating rating

The top right box shows the system’s energy efficiency rating for heating.

System domestic hot water rating

The bottom right box shows the system’s energy efficiency rating for hot water. This rating is only applicable if the heat source is a combi boiler or a heat pump with a built-in water cylinder.

The extras

The bottom left box shows the optional system ‘add-ons’. These include solar thermal, a hot water storage tank, thermostats and a supplementary heater. Whenever one of the additional components is part of the overall system package, the box will be checked. These components can affect the overall heating and hot water efficiency of the system e.g. solar thermal will improve the efficiency.

Are you ErP ready?

It’s just under a month until the new ErP Directive comes into play, but it seems that many installers are still uncertain how to calculate a system’s energy efficiency rating.

We ran a short survey with installers and it showed that whilst most understand the purpose of ErP and energy labelling, over three quarters still do not feel confident in calculating and producing the required energy label for a system package to hand to their customer.

In response to this feedback, Nu-Heat has created a short instructional video to support installers in calculating a standard heating and hot water package energy rating and label themselves, without using any supplier tools that can be restrictive:

All an installer needs is the boiler and thermostat manufacturers’ product fiche, Figure 1 and Figure 5 forms (easy-to-follow versions can be downloaded from www.nu-heat.co.uk/erp) and access to a computer to generate the system label via the official EU website. It’s that simple!

ErP FAQs

If you’re still unfamiliar with ErP, you might find our FAQs helpful.

What is ErP?
The Energy Related Products Directive, or ErP, aims to improve the efficiency of heating products and systems installed in properties throughout the UK. There are two separate parts to ErP:

  1. Ecodesign

    Ecodesign ensures that the products available on the market, such as heat pumps or boilers, meet strict efficiency requirements. Inefficient products will no longer qualify for a CE mark, meaning they cannot be sold in the UK. The responsibility for complying with this part of ErP lies with manufacturers and suppliers.

  2. Energy labelling

    Energy labelling affects space and water heaters. The labels look similar to those you already see on white goods such as fridges or washing machines, providing a clear rating to show product efficiency.
    Energy labelling applies to single products, such as a heat pump, as well as complete heating system packages.

    Individual product labels will be provided by manufacturers.

    Responsibility for producing the package system label lies with the installer.

 

What is a system package?
A system package is when a new heat source, such as a boiler or heat pump, is being installed together with a thermostat, hot water storage tank, solar collectors or a supplementary heater. If only one product is being installed, it does not count as a ‘package’, meaning that an energy efficiency label for the system is not required.

Does the heating system have an impact on the package efficiency rating?
No, the chosen heating system does not affect the package efficiency rating. Only the heat source e.g. boiler, thermostat, solar input or additional heat sources and controls have an impact on the system package rating.

When should the energy efficiency rating for a system package be calculated?
To comply with the legislation, an installer needs to show the system’s energy efficiency rating to the customer before they decide to purchase. Calculating the efficiency is simple and only takes a couple of minutes. Watch this short video to find out how to do it yourself.

Does the system package ‘label’ have to be displayed on the heat source?
No. The system package label must to shown to the customer but doesn’t have to be an actual sticky label. The label can be printed onto a standard A4 piece of paper, or even emailed over to the customer.

What ErP means for installers

Most installers will be aware of ErP (the EU Energy Related Products Directive) – one of the biggest changes to the heating and plumbing industry in years.

Whilst many have a basic understanding of ErP and what it means, it can be difficult to see exactly what is required of an installer when providing a customer with a new heating system.

In this post we breakdown ErP so you know exactly what to expect when the legislation kicks in this September and how Nu-Heat is helping to make this straightforward for installers.

Energy labelling

Firstly, what is ErP?

In basic terms, the purpose of ErP is to improve the efficiency of heating products and systems installed in properties throughout the UK. It will give homeowners a clear label to look out for when choosing a new heating system, allowing them to compare a product or complete system’s energy efficiency like-for-like, promoting a ‘greener’ way of thinking.

There are two separate parts to ErP and installers, manufacturers and suppliers must comply with these from 26th September this year.

  1. Ecodesign

    Ecodesign ensures that the products available on the market, such as heat pumps or boilers, meet strict efficiency requirements. Inefficient products will not qualify for a CE mark, meaning they cannot be legally sold in the UK, effectively eliminating poor performance models.

    All heat pumps, solar thermal systems, cylinders and thermostats supplied by Nu-Heat meet the Ecodesign criteria.

  2. Energy Labelling

    Energy labelling will affect space and water heaters. The labels look similar to those you already see on white goods such as fridges or washing machines and will provide a clear rating to show product efficiency.

    Products are split into categories from A+++ to G. Only renewable technologies such as heat pumps will reach the top classes such as A+ or A++, whilst an extremely efficient boiler could expect to be in class A.

    Energy labelling applies to single products, such as a heat pump, as well as complete system packages, explained below:

    A heat pump on its own will have a product energy label, such as A+. This heat pump could then be installed with room thermostats and underfloor heating, creating a ‘package’ that requires a combined energy label of its own.

How ErP affects installers

From 26th September 2015, installers will have to:

  • Make customers aware of the energy rating of the products they are thinking of having installed, e.g. a heat pump or boiler, etc. All manufacturers will have this clearly displayed on the product
  • Provide a system label if installing a package such as a boiler, UFH and stats. Some suppliers will do this for you (generally if you buy all of the products from them), or you might have to calculate this yourself. This is very simple to do, and Nu-Heat will be providing online support to help you with this process.
  • Ensure the product fiches (these provide basic data relating to the particular model of appliance), labels and system label are all handed over to the customer

All of the information needed for the above will come from your supplier or product manufacturers, so on the whole it’s quite simple.

How Nu-Heat is helping installers with ErP

As you’d expect, Nu-Heat will be ErP ready in time for 26th September, providing you with product fiches and labels as well as creating system package labels for all of our heat pumps, whether purchased with our underfloor heating or paired with another heat emitter.

We are also producing some additional online support for any installer working with our underfloor heating systems.
