The Heat Pump Association… – Who are we?
The Heat Pump Association…
Govt
Commercial HVCA Heating Sector
HPA CLIENT
HP Industry Members
Public/ Domestic
Trade Association of manufacturers/distributors
What Are the Specific Objectives of the HPA? Promote Increased deployment of Heat Pumps –
a) Improve the Quality of Design & Installation of Heat Pumpsb) Ensure Govt’s informed & HP’s are adequately represented in legislation & supported by incentives c) Widen HPA Role & Engagement

So…. What exactly is a heat pump?
A device which pumps heat!
It transfers energy from a low temperature level to a higher level!

Efficiency = output power/input power Efficiency > 100% 1 kW
Efficiency = “Coefficient of Performance” (CoP)
Outside
CoP here = 3kWheatout /1kWelectricity in

You all probably have a heat pump at home!
A domestic refrigerator!

Can Heat Pumps Integrate with Existing Heating Systems? Yes
Can Existing Heating System be Used? Heat pumps work most efficiently when the heat emitter is designed to work at lower temperatures compared to fossil fuel systems
Radiators and Fan coils max 55°C
Under-floor heating max 45°C

Make sure Installation company is MCS registered and fully trained on your proposed products Check it & Ask for reference sites
Insist On It!

Educating the User
This is forgotten, the occupants are left with a system they can’t understand or can’t control.
Make sure you’re shown how to use the system and left with a user manual!
