New ‘LOT 20’ Energy Efficiency Standards – Are You Ready?

// heating and ventilation

The drive for increased energy efficiency across all domestic heating types and associated products is continuous. On the 1st January 2018, a new regulation affecting “the ecodesign requirements for local space heaters” will be implemented. This derives from an EU Commission Regulation transposed into UK Law under the Energy Related Products Regulations (ERP). This new regulation is often referred to as ‘LOT 20’ and requires any new local space heating system installed from this date onwards to be compliant with set energy efficiency standards.

The Electric Heating Company (“EHC”) pride themselves on providing innovative heating solutions and have been planning for LOT 20 for over a year. Unlike many electric heating manufacturers and suppliers, EHC launched their LOT 20 compliant product range in January 2017. As a result EHC are confident their products and controls provide a ‘tried and tested’ solution which meets these new standards with an enhanced control to maintain the quality of heating provided to customers.
The aim of LOT 20 is to reduce the energy consumption in our homes through accurate management and control of electric heating appliances and minimise wasted energy. To meet the objectives of LOT 20, better use of intelligent timers, controls and sensors must be made. Standard on/off heating appliances without such controls will no longer be compliant and manufacturers and distributors will no longer be able to sell these.
Any new local space heating system installed from 1 January 2018 onwards must be compliant with the new LOT 20 performance standards. The legislation is not retrospective, so existing systems in place will not be affected.
To be LOT 20 compliant, heaters will in general now need to include 3 key features:
• 24/7 time and temperature control, either built in or through wireless/WIFI APP.
• Electronic thermostatic control for accurate room temperature measurement.
• Open window/door recognition so the heater can reduce usage if the user leaves a door or window open reducing the room temperature rapidly. Some radiators will have a have a smart start facility included, which allows the heater to choose the time it engages to bring the room up to the required temperature set by the user.

All heaters must also meet a minimum seasonal space heating energy efficiency requirement too.
All EHC products now LOT 20 compliant since January 2017:
• DSR Electric Combination Radiators
• EHC RF Electric Combination Radiators
• DSR Visage Panel Heaters 
• DSR Convecto Rad Panel Heaters 
• ecoSave Dynamic Electric Heaters
For EHC customers, this range of LOT 20 compliant products continue to offer full controllability, ease of operation and, on the correct electricity tariff, continue to be affordable to run. The customer will still be able to regulate the time and temperature of their heating system to suit their lifestyle through individual control on the radiators and central control via a programmer and room thermostat. This type of controllability will undoubtedly continue to help achieve energy cost savings throughout the year and meet the overall aim of this new LOT 20 regulation.
