Lot 20 is EU Ecodesign legislation that applies to electric heating. EU 2015/1188 comes into force from January 2018. All subsequent installations will have to comply with a minimum efficiency standard of the Energy Efficiency Directive. The focus is on removing poorly controlled heaters from the market and replacing them with controls that feature temperature, timer, presence and open window detection features amongst others.
As a control company Prefect has, for many years, championed the use of clever controls, recognising their ability to reduce energy consumption and therefore carbon emissions, and as a result welcome any advance in control technology.
The important part to understand of this legislation though, is that heaters fitted with basic controls will no longer be permissible – but that doesn’t mean the control unit has to be integrated.
Prefect has two alternative control methods to a fully integrated controlled panel heater, which more than comply with the directives for functionality of Lot 20.
Ecostat 2 – local control
Firstly, the Prefect Ecostat 2 range of controls is supplied with a bespoke slave heater. This option provides complete control as a result of its tried and tested tamper-proof design and impressive range of features. The specifications required under EU law are far exceeded with the impressive Ecostat range. This master control, fitted separately from the panel, also makes sense from a future-proofing perspective, enabling upgrades and new innovations to be taken advantage of more affordably, by simply replacing the control rather than the a fully integrated control and panel unit.
Ecostat is quick, simple and inexpensive to install and easy to use. A single coded handset programmes individual wall units with on and pre-set run times, minimum/maximum temperature and temperature boost times. Occupants are able to make adjustments within pre-determined parameters. But ultimate control is with the energy manager as heat is only used when needed.
PrefectIrus – Central control
The other Option from Prefect is their central control system for heating, lighting, water temperature, sound and humidity levels that are all monitored, measured and managed via the central control system from anywhere in the world with internet access.
PrefectIrus algorithms cleverly learn the environmental conditions for individual rooms – for example, how much heat is required, the time it takes to reach temperature and dissipation rates. Combined with sensors for lighting, sound and humidity levels, the software balances comfort and energy use for the benefit of both students and energy managers.
Managers are in control via the comprehensive user display connected to the central controller. This accepts and interprets data from individual room nodes through the existing electrical wiring within the building. Using mains borne signalling means the system is quick and cost-effective to install, with very little disruption to infrastructure. Better still it does not need rooms to be unoccupied, so installation can be carried out at any time of the year, not just during holiday periods.
As with Ecostat 2 this option exceeds the requirements laid down in Lot 20.
Prefect has the perfect pedigree
20 years’ experience of manufacturing energy efficient control systems means Prefect is in the perfect position to ensure customers are installing the logical, cost-effective and efficient option to be fully compliant with Lot 20 legislation. The new Lot 20-compliant packages from Prefect, that include the slave heater along with control from either Ecostat or as part of the Prefectirus system, will be available from November 2017.
