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.

A closer look at… the Nu-Heat neoStat

neoStat from NuHeat

The neoStat is a programmable thermostat that can be partnered with the neoHub to unlock a wider range of ‘smart’ functions. It’s a great solution for a homeowner looking for precise and flexible control of their heating system.

The neo vs. standard thermostats
Nu-Heat offers a range of programmable thermostats, with the neo being one. The main difference is that the neoStat can offer remote control of the heating system through a downloadable app. By upgrading to the neoHub and syncing the neo system to a smartphone or tablet, it opens up features such as Geo-Location which enables the thermostat to switch the heating on and off depending on the user’s proximity to the property.

The neoStat ensures that the underfloor heating system is perfectly timed and set to match the lifestyle of the homeowner.


Installing a neoStat

The neoStat is installed like any other wired thermostat and is suitable for any project. The neoHub is required to enable access to the app and remote functionality. The Hub looks similar to a wireless router used for connecting to the internet.

Because each individual neoStat in the property can be controlled via a smartphone or tablet, there is no need to directly engage with the thermostats. If decoration of the property is very minimalist, the remote control option, via the downloadable Nu-Heat App, means that the thermostats can be hidden away, out of sight.

Functions of the neo system

Aside from the standard functions you’d expect from a thermostat, the neo system also offers:

  • Geo-Location
    This function makes use of the user’s phone location services to turn the heating off when a certain distance away from the property and back on again when returning. This can be a great back-up that will automatically turn the heating off when the property is empty – perfect for weekends when the heating may be programmed to be on all day.
  • Optimum Start
    This delays the start-up of the heating system to the latest possible moment to avoid unnecessary heating and ensure the property is warm at the programmed time. Optimum Start uses the rate of temperature change information to calculate how long the heating needs to raise the building temperature 1⁰C and starts the heating accordingly. The neo automatically adjusts the heat-up time throughout the year.
  • Holiday mode
    A function most are familiar with, holiday mode reduces the set temperature in the property to the frost protection temperature setting. It will them automatically return to the program mode on the homeowner’s return.
  • Sensor selection
    The neoStat enables a choice to select between air temperature, floor temperature, or both. When both sensors are enabled, the floor sensor is used as a floor limiting sensor and is designed to prevent the floor from overheating.

A basic guide to choosing the right thermostat

Controllability is an important consideration when installing underfloor heating – one of the biggest areas of wastage from a heating system is down to poor controls.

Lifestyle tends to dictate the amount of controllability required. Will there be a benefit to thermostats that offer remote controllability, enabling the heating to be turned on or off on the way home from work, or in a holiday home? For someone who spends most of their time at home with a standard routine, a simple dial stat may meet requirements perfectly.

To help make the choice of thermostat easier, we look at the five most popular in our range, explaining what they offer and the projects they are most suited to.

Nu-Heat neoStats
neoStat with optional neoHub and app

  • An all singing, all dancing thermostat that allows remote control of the heating system through a downloadable app
  • Holiday, temperature hold and temperature over-ride functions to name a few
  • The energy saving Optimum Start calculates the amount of heat up time required to ensure warmth when needed, automatically adjusting this throughout the year

Dial thermostat
Standard dial thermostat

  • Offers simple and effective individual room-by-room control
  • Similar to standard central heating controls, so most will be familiar with this type of stat and how it operates
  • Suitable for the majority of projects

PbS thermostat
Push button programmable thermostat

  • Individually programmable time and temperature control. Programmable thermostats help improve energy efficiency and responsiveness as rooms are controlled at the precise temperature required throughout the day
  • Particularly suitable where different areas of the house need to be programmed to heat at different times of the day, such as heating bedrooms for shorter periods and living rooms from late afternoon into the evening
  • Suitable for the majority of projects

PbR thermostat
Wireless programmable thermostat

  • Due to being wireless, these thermostats can be fitted into an existing building without the need to chase wiring into the walls, causing less disruption
  • Same functionality as the push button programmable thermostat
  • Often the best choice for renovation projects

Central touchscreen console
Low voltage programmable thermostat and central touchscreen console

  • The best solution for larger new-build projects that incorporate building management control systems (BMS) as they integrate seamlessly with whole house monitoring and control systems
  • The touchscreen console makes it simple to programme and adjust all the thermostats from one central position, meaning individual thermostats can be hidden away in a cupboard
