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 and access to a computer to generate the system label via the official EU website. It’s that simple!


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.

Your Nu-Heat journey, from start to finish

Nu-Heat UFH system

Nu-Heat is committed to designing bespoke energy efficient heating systems that perform in every project, but what really sets us apart from our competitors is the way we work with you – starting from the very first time you get in touch, to years after the system has been installed.

Here’s what you can expect when choosing Nu-Heat for your project…

Our first conversation – helping you to choose the right solution
When you first get in touch with Nu-Heat, our aim is to help you choose the right solution for your project.

Our Business Development Team take all of our new enquiries and will talk through the details of your project and what you are looking to achieve, whether you are hoping to install underfloor heating in a new build or a renovation, or if you are looking to install a fully integrated renewable solution.

Once we have an understanding of your project and whether our products will be suitable, we will ask for a set of your project plans. Plans help our Estimating team to pick the most suitable solution and give an accurate quote price. Read more about why your plans are so important.

If we don’t think underfloor heating or renewables is right for your project, we will always let you know.

Introducing your Account Manager
As soon as we log your plans, you are allocated an Account Manager who will handle your project from start to finish. They will be your first port of call if you ever have any questions and you can expect them to get in touch if we need more information or clarification on your project.

Estimating provide a bespoke quotation
Your Account Manager sends your plans to our Estimating Team who begin by checking that everything is to scale and measure the areas requiring UFH. They also estimate the heat loss of the building using insulation details, looking at building shape and amount of glazing, checking for any areas with voids or high ceilings.

The quote, with an estimate cost for the most suitable system for your project, is then sent back to your Account Manager who will double-check everything again before sending it on to you.

A site visit, if required
Some projects are more complicated than others and may require specialist evaluation, especially where renewables are involved. If your project needs this, we will arrange for one of our Field Sales Team to visit your site to talk through the options.

Your finalised quote
When you are confident and happy with the solution we have recommended and any revisions have been made, your Account Manager will send you a finalised quote. This will reflect the final price based on the most economical and efficient solution for the project based on how the property will be used.

Placing your order
Now you have the final price, it’s time to place the order with your Account Manager so that the project can progress to our Design Team…

The design phase
An important stage in your project journey, this is where our team of designers double-check all of the information you have provided.

We will then produce accurate heat loss calculations and CAD drawings with detailed tube layouts to provide you with a system that is simple to install and designed to perform.

We always get drawings back to you within 10 days.

Time to take your delivery
When you have checked over the drawings and everything is ready to go, we will contact you to arrange delivery. We can arrange a full or part delivery on the date you require.

You will also receive a comprehensive handover pack, manuals and system user guides.

Continued support, when you need it
We like to think that your system will be installed quickly and simply, without any problems. If you do need some support, whether you are the installer or system owner, our Technical Team are available on the phone to help with any queries and we also have a FAQ for troubleshooting on our website.

Our Field Service Engineers are also able to help with any on-site support, something that can prove useful if you are installing a complex renewable solution and need help with commissioning.
