What is a Heat Pump?


A heat pump can be a highly efficient replacement for conventional fossil fuel boilers, for heating and/or hot water. Heat pumps absorb free energy (heat) from a low-temperature source (air, water or ground) and upgrades it to a higher temperature, via the refrigerant cycle, (like your fridge at home but in reverse (fig.2). Efficiency ratios range from 3:1 to 5:1 (300-500%), i.e for each 1kW of electricity consumed between 3kW - 5kW of heat energy can be transferred (conventional fossil fuel boilers are around 85 - 96% efficient) - therefore heat pumps are more cost effective, eco-friendly and use renewable energy for the greater good of our environment.


The refrigerant cycle basically comprises of 4 essential components (fig.1). 1) The Evaporator - absorbs heat from renewable source (air, water, ground). 2) The Compressor - raises pressure hence temperatures of absorbed heat. 3) The Condenser - rejects upgraded heat to the source inside (air or water). 4) The Expansion Device - reduces pressure/temperature to allow evaporation (Heat absorption) at low temperatures.

Types of Heat Pump? Air to air:

Heat absorbed from air outside and transferred to air inside (heating and cooling only, no hot water)

Air to water:

Heat absorbed from air outside and transferred to water inside (heating and/or hot water)

Water to air:

Heat absorbed from water (ground or lake) and transferred to air inside (heating only, no hot water) Heat absorbed from water (ground or lake) and transferred to water inside (heating and/or hot water)

Water to water: [ Air to air: is the most efficient Water to water: is the least efficient heat pump system ]

Heat Pumps and the Environment We all have a responsibility, in these times of concern about our global environment, to set an example in terms of supporting government objectives in the reduction of carbon emissions. In addition to Space Air’s internal environmental protection policy, we ensure that our customers are informed about the most energy efficient climate control solutions available. Space Air conducts ongoing environmental awareness campaigns through the media, free seminars, publications and regular staff and customer training. The Altherma™ heat pump is a low carbon, energy saving heating/hot water system, incorporating the latest heat exchanger and inverter technology. Operating on R-410A, an energy efficient non-ozone depleting, non-toxic, non-corrosive, non-explosive refrigerant and utilises state-of-the-art electronic controls in Altherma™ with unique twin temperature settings for heating and hot water. These technologies incorporated harmonised to achieve the highest recorded operating efficiencies in all weather conditions.

Facts, Statistics and Benefits of Altherma™ • 84% of energy consumed at home is for heating and hot water • UK 2005/06 average winter temperature is 1.1°C min and 6.6°C max ( • UK annual average ambient temperature ranges between 8-11°C • The average UK climate is considered ideal for air to water heat pump applications as direct replacements for conventional central heating boilers • The boiling temperature for R-410A refrigerant is [minus] -53°C


• High efficiency up to 500% (5:1 COP) • No flues, no ventilation and no gas supply needed (no combustion), therefore reducing health and safety risks • Operation down to -15°C ambient temperature (-20°C with backup heater) • No starting current and no power surge due to inverter control • Weekly legionella automatic protection • Manufactured by Daikin, one of the largest dedicated heat pump manufacturers in the world

The Altherma™ System Altherma™ manufactured by Daikin Europe and supplied by Space Air is an air source, air to water, heat pump system designed to replace the conventional gas, oil or all electrical central heating boiler. Altherma™ provides a compact, high efficiency, low carbon, low maintenance means of providing heating and/or hot water from the same system, with optional solar kit connection. The weatherproofed outdoor unit (Split or Monobloc, both available in 6 capacity sizes), contains the ‘refrigerant cycle’ (fig.1), both systems are extremely quiet in operation and can be ground or wall mounted. Altherma™ has an average seasonal performance efficiency of 320%. Seasonal performance efficiency is - Total energy throughout the year used x total energy consumed comfortably

*Altherma™ System Efficiencies (30-75% savings) Definition of ‘Renewables’ or ‘Renewable Energy’

Definition of Carbon Footprint

Renewable energy is energy derived from resources that are regenerative or for all practical purposes cannot be depleted. For example, the air around our homes is a renewable, regenerative resource from which Daikin’s Altherma™ air source air to water heat pump absorbs energy in the form of heat, which results in energy savings as indicated in the graph below.

Carbon footprint is a measure of carbon emissions based on energy consumption per kWhr and fuel type i.e direct electric, mains gas, LPG or oil. As indicated in the graph below.

How The Altherma™ System Can Help SAP / Part L TER / Code For Sustainable Homes • SAP (Standard Assessment Procedure) is the system for assessing the energy performance of dwellings. Indicators of the energy performance are energy consumption per unit floor area and energy cost rating (the SAP rating), based on CO2 emissions and a Dwelling CO2 Emission Rate (DER). • The Dwelling CO2 Emission Rate (DER) is used for the purposes of compliance with building regulations. It is equal to the annual CO2 emissions per unit floor area for space heating, water heating, ventilation and lighting, less the emissions saved by energy generation technologies, expressed in kg/m2/year. • TER (Target Emission Rating) is a calculation of Part L1A set by the Government and should be lower than the DER by 20% (Variable). (DER x fuel factor less 20% = TER). • The Code of Sustainable Homes is a star rating system set to exceed Part L1 Building Regulation targets and became mandatory from 1st May 2008. The Code sets minimum standards for energy and water use at each level. The Altherma™ system will help achieve a higher star rating, in accordance with the Code for Sustainable Homes where.... 1 H = 10% better than Part L 2 H H = 18% better than Part L 3 H H H = 25% better than Part L 4 H H H H = 44% better than Part L 5 H H H H H = 100% better than Part L (on heating and water only) 6 H H H H H H = Rating is considered as a carbon neutral home; ie: zero net emissions of CO2 from all energy (heating, hot water, lighting, power etc.) used in the home.
