Glen Dimplex Heating & Ventilation -
Meeting Regulations with Electric & Renewable Heating

heat pumps - renewable heating - environment - refrigerant - Glen Dimplex

Air Curtains

Our extensive air curtain portfolio includes surface and recess mounted models using electric heat, water heat or as ambient units for commercial and heavy commercial applications. We also offer a range of bespoke architectural units that are perfect for applications where design requirements are particularly important, as well as a range of heavy duty industrial products designed for the largest openings.

Electric Fires

All leisure and hospitality applications, whether that is a restaurant or a gym, could benefit from the use of an electric fire or stove to improve the ambience and increase customer comfort. Dimplex offer a range of fires and stoves that can be both installed or ‘plug-and-go’, with the options of use with or without heat for year-round operation. Dimplex offers a range of modern or traditional styles to suit any environment and clientele, creating a warm and enticing feel to any room. Electric fuelled fires and stoves have many advantages over gas or solid fuel including:

  • Don’t need a gas line & annual maintenance
  • No carbon monoxide risk
  • Control over heat output
  • No need for chimney/flue
  • Cleaner burn – no need to clean up ash
  • Not a real flame so safe for open public use – children, elderly, animals, etc

Meeting the UK Government’s Strict Commitments

Driving the development of Glen Dimplex’s portfolio is the UK government’s commitment to sustainable growth and the green agenda. As part of this green approach, the Greater London Authority is planning a carbon tax on new developments in the capital. In essence, developers must reduce the Dwelling Emission Rate (DER) of a dwelling to 35% below the Target Emission Rate (TER) required to secure a pass in Part L of the England and Wales Building Regulations. The remaining carbon, expressed in tonnes, must then be offset in the form of an abatement payment which is set by each individual borough.

A Low Carbon Heating Solution

Heat pumps extract as much as 75% of their heating energy from the environment. Building carbon emissions for heating can be reduced by as much as 50% compared with gas fuelled heating systems. This is an obvious benefit when considering building regulations Part L compliance and planning obligations requiring minimum contributions from renewable energy.

Heat Pump Technology

A heat pump heating system consists of 3 components: the heat source, the heat pump itself and a heat distribution and storage system. Heat pumps can produce more energy than they consume by using the conventional refrigeration cycle to absorb heat from the environment and raise it to a suitable level for heating.

1. 75% of the energy is taken from the environment i.e. the air or ground and transferred to the heat pump.

2. 25% of the energy is sourced from the national grid in the normal way of supplying your electricity. This is used to operate the heat pump but with very low consumption.

3. The energy from the air or ground is transferred to the refrigerant inside the heat pumps evaporator. This causes the temperature of the refrigerant to rise and change state from liquid to gas.

4. The refrigerant gas is then compressed, using an electrically driven compressor, reducing its volume, but causing its temperature to rise significantly.

5. A heat exchanger (condenser) then extracts the heat energy from the hot refrigerant to heat water for central heating, underfloor heating or domestic hot water.

6 After giving up its heat energy, the refrigerant turns back into a liquid and can absorb energy from the environment, allowing the cycle to begin again.

Using Energy Efficiently

  • Heat pumps are among the most efficient heating and hot water systems available today. Approximately 75% of the energy needed for heating comes from the environment.
  • This means that for every 1kWh of electricity used to power the heat pump compressor, between 3 and 4kWh of heating energy are produced, giving the heat pump an efficiency of 300-400% or higher.
  • The heat pump’s “efficiency” is known as it’s “Coefficient of Performance” (CoP). This is simply a ratio between the proportion of the total energy supplied that can be extracted from the environment and the amount supplied by electricity to run the heat pump compressor. The higher the CoP, the more “free” environmental energy the heat pump is using!

Building Information Modelling

Dimplex supports Building Information Modelling (BIM) for the generation of shared knowledge to equip architecture, engineering, and construction professionals with the insight and tools to plan, design, construct, and manage buildings and infrastructure more efficiently and cost-effectively throughout a facility’s lifecycle; from earliest conception to demolition.

Dimplex currently supports BIM for the following product ranges: air curtains and overdoor heaters; storage heating; direct acting heaters; ground source heat pumps; air source heat pumps; heat pump accessories; hot water heat pumps; district heating heat pumps; domestic hot water; fan assisted radiators; towel rails; bathroom radiators; tubular heaters; plinth heaters; outdoor fires; infrared heaters and secondary heating.
