Heat Pumps

A heat pump is a device that transfers heat from one place to another, providing both heating and cooling functions. By utilizing a compressor, pump, and working fluid, heat pumps can extract heat from the outside air and transfer it inside, effectively replacing traditional heating systems. This process enables them to supply hot water and heat radiators, offering an energy-efficient solution for homes. The coefficient of performance (COP) measures a heat pump's efficiency, indicating how much heat energy it can produce compared to the electrical energy input. Overall, heat pumps are a sustainable choice for enhancing the comfort of a living space while reducing energy consumption.

1. Heat Pumps What is a heat pump? What does it do? How does it work?

2. What is a heat pump? Air Source Heat Pump Replaces a Gas Boiler Supplies Hot Water Heats radiators

3. What is a heat pump? Heat Pump

4. What does a heat pump do? 70 Hot Water 60 50 Temperature ( C) 40 Radiator 30 20 Inside 10 Outside 0 15th Feb 16th Feb 17th Feb 18th Feb 19th Feb 20th Feb 21st Feb 22nd Feb

5. How does a heat pump work? Compressor Pump Pipe Cold Hot Low Pressure Evaporator High Pressure Working Fluid Condenser Expansion Valve

6. Expansion Valve The working fluid cools down dramatically when it expands

7. Compressor Pump The working fluid heats up dramatically when it is compressed

8. How does a heat pump work? Compressor Pump Cold water in Pipe Insulation Expansion Valve Hot water out

10. How does a heat pump work? Compressor Pump Cold water in Pipe Insulation Expansion Valve Hot water out

11. How does a heat pump work? Coefficient of Performance, COP 6 1 kWh of electrical energy produces 5 kWh of heat energy 5 COP 4 1 kWh of electrical energy produces 3 kWh of heat energy 3 2 15th Feb 16th Feb 17th Feb 18th Feb 19th Feb 20th Feb 21st Feb 22nd Feb

12. Summary Air Source Heat Pump Replaces a gas boiler Supplies hot water to a home Extracts heat from cold outside air Coefficient of Performance (COP) is typically ~ 3 An ASHP delivers more heat energy than the electrical energy it consumes Reduces CO2 emissions associated with heating
