Recently approved amendments to EU energy efficiency directive will require individual room controls for new buildings or replacement boiler systems where technically feasible
Revisions to the EU’s Energy Performance of Buildings Directive (EPBD) that will make individual room temperature controls mandatory, pending certain conditions, have been welcomed by manufacturer Worcester Bosch as a reflection of current best practice within the UK boiler industry.
The recently implemented Boiler Plus energy efficiency standards for domestic heating systems in England omitted requiring installers to ensure room specific controls in favour of other initiatives. These initiatives include requiring time and temperature controls to be fitted to all gas and oil boiler installations.
However, amendments to the EPBD now demand that room controls, such as Thermostatic Radiator Valves (TRVs), are included with heating systems in new buildings or when older technology is replaced. Worcester Bosch noted that this stipulation in the EPBD will only apply where their use is technically, economically and functionally feasible.
The EPBD is viewed as a central component of EU energy policy to help realise the aims of a decarbonised building stock by 2050 through measures that include the use of smart building technologies.
Revisions to the directive that include mandatory room controls have received European Parliament and EU Council backing, with implementation of the measures at a member state level required in less than two years after the revisions come into effect.
Worcester Bosch has argued that TRVs are already a popular solution for improving energy efficiency of domestic heating. The company cited the 2014 English Housing Survey Energy Report, which concluded that 76 per cent of homes with gas central heating made use of a full or partial system of TRVs.
Martyn Bridges, director of technical communication and product management with Worcester Bosch said, “Using individual heating controls in conjunction with room thermostats offers individual room comfort while still providing a boiler interlock from the room thermostat sited in a location that should offer an overall mean temperature of the house.”
“TRVs are far more sophisticated, creating heating zones and supplying a controlled level of heating to suit individual rooms. By making their installation a legal requirement, thousands more homes across the UK can now benefit from the energy efficiency and cost savings that they provide.”
The company said that the potential benefits of TRVs can be increased through adoption of smart controls such as its EasyControl system that can allow heating and hot water needs to be controlled remotely through the internet.
Mr Bridges said that the amendments to EPBD would ensure TRVs, which are not new to the market, were not being overlooked by industry.
He added, “By making it a legal requirement, this not only validates best practice, but also ensures that TRVs are considered for all new and replacement boiler scenarios.”
