Heat Pumps in Northern Ireland

• Benefits to the community
• Most efficient use of electrical energy
  350-400
• Can be powered by other Renewable Energy sources
• Lower CO2 Emissions
• No Flue Emissions
• No risk from Oil or Gas leaks

3

• Benefits to Owners
• Reduced running costs
• No storage required unlike Oil or Solid fuel
  systems
• No Fuel to re-order
• No deliveries to organize
• No cleaning or emptying ashes
• No annual service or safety checks
• Makes the most of domestic renewable generation
  (e.g. Wind turbines, P.V. or Hydro)

4

• What do I need to be able to install a Heat Pump?
• An Electricity supply (3 phase for units above
  16kw)
• A compatible heating system
• A properly insulated building
• A Heat source

5

• Where does the Heat come from?
• A Heat Pump utilises heat stored in the
  environment and converts it to usable energy for
  space heating and domestic hot water preparation.
• Approx. 4kw of heat from 1kw of electricity.

6

• The Heat source.
• Ground Source Type
• Ground Loops - Require a substantial footprint
  area.
• Bore Holes - Only need access for boring rig.
• Air Source Type
• Outdoor units use the surrounding air.
• Can be accommodated in small areas, even city
  gardens.
• Indoor units can even be installed several
  storeys up.
• Water Source Type
• Ground water can also be used as a heat source,
  if conditions allow.

7

• Which heat source is best?
• Water
• Has the highest c.o.p. (efficiency), but can be
  challenging to install.
• Ground
• Next best c.o.p. best suited to buildings with
  plenty of ground space available e.g. farms,
  rural housing.
• Air
• Variable c.o.p. (dependant on air temperature)
  but average is only marginally down on ground
  source (very efficient in UK/ Ireland).
• Easiest installation in built up areas.
• All types show reduced energy use and fuel costs
  over fossil fuel systems.

• Why does everyone not fit Heat Pumps?
• Heat pumps are not as well understood by
  Designers and Installers as fossil fuel systems
  are.
• To many installations already done by badly
  trained installers cutting corners to save
  installation costs.
• Electricity traditionally seen as expensive
  energy
