British Gas launches Dimplex Quantum Tariff
British Gas and Dimplex have partnered to launch the British Gas Dimplex Quantum Tariff, the UK’s most advanced electric storage heating tariff for use with the Dimplex Quantum Storage Heater.
How can the Zeroth Energy System overcome the challenges of overheating in large residential developments?
The Zeroth Energy System uses an ambient loop designed to operate at 25oC. This reduces heat losses through the distribution network that could otherwise result in overheating occurring in corridors and communal spaces.
Zeroth Energy System and district heat networks
The tightening timescales for reaching the 2050 net-zero carbon target require us to accelerate our efforts at the decarbonisation of heat. Ambient loop systems, such as the Zeroth Energy System, are being increasingly specified for multi-occupancy developments due to their high efficiency and capability to reduce a building’s CO2 emissions.This raises the question: can the Zeroth Energy System be specified in a district heating priority area, and can it connect to the district heating network?
Will the outcomes of COP26 significantly speed up the uptake of low carbon technologies?
We are all waiting to see what the real impact will be from the climate summit COP26 for the construction sector, specifically with regard to the decarbonisation of heat. One of the insights that came out of the second day of the summit, which featured a session on clean technology and innovation, was delivered by UK Prime Minister, Boris Johnson:
‘By making clean technology the most affordable, accessible and attractive choice, the default go-to in what are currently the most polluting sectors, we can cut emissions right around the world’.
Which heating and cooling emitters can I use with a heat pump?
Any hydronic heating and cooling emitter such as fan coils, radiators or trench heating, could be used with a heat pump.
There are a number of factors, however, which will ultimately impact the final specification. These include thermal requirements, such as whether the building needs heating only or heating and cooling, control requirements and design preferences, such as whether to have the emitter recessed or on view.
Which is better - a ground source or an air source heat pump?
When it comes to specifying heat pumps, we are often asked which is better: a ground source or an air source heat pump. In actual fact neither are ‘better’. The decision comes down to design factors on a specific project, which will drive the specification to ensure the demands required by the building and occupants are met.

What is EN 15316?
EN 15316 offers guidelines that set out a common calculation method to estimate the energy use and energy performance of heating systems in buildings. The values are calculated for the whole installation and help to analyse the impact on energy performance. The values also help to establish energy performance indicators such as the Seasonal Performance Factor (SPF).
What is EN 14825?
EN 14825 sets out the temperatures, part-load conditions, and calculation methods for determining the Seasonal Coefficient of Performance (SCOP) and Seasonal Energy Efficiency Ratio (SEER). It applies to the operation of air-conditioning units, process chillers, and particular types of hybrid heat pumps. The values used to define the SCOP can be calculated or measured. If measured values are applied, the standard covers the applicable test methods.
What is EN 14511?
EN 14511 sets out standardised performance and rating terms for air-conditioning units, heat pumps and liquid chilling packages that supply space heating or cooling. EN 14511 is used for a determination of the Coefficient of Performance (COP) that gauges the performance of a heat pump.
What is diversity in HVAC systems?
What is diversity in HVAC systems, and how does it affect HVAC system design and specification for residential developments?
Diversity in HVAC systems within medium to large scale developments acknowledges that it is unlikely the maximum demand of all individual users of the system will arise concurrently. The total heat demand in a building is likely to be lower than the maximum or peak demand at various points in the heat network.
What is COP and EER?
The Coefficient of Performance (COP) and Energy Efficiency Ratio (EER) are measures of a heat pump or heating and cooling solution’s efficiency. They indicate a ratio of useful heating or cooling produced by the unit against the energy it consumes. For example, the COP of a heat pump that can provide 3kW of heat against the input of 1kW of electricity is 3. The EER that generates a cooling effect of 12BTU against the input of 1kW of electricity is 12.
What Building Regulations are changing during 2020?
2020 has been dubbed the year of change for the built environment, with Government keen on updating compliance targets for new and existing dwellings to enforce change in industries HVAC strategies.
