Ready to solve the problems other engineers can't?
Air Sourced is looking for an experienced Renewable Heating Service Engineer to join our technical team, with a particular focus on air source heat pumps.
This is much more than a routine service role. You'll be diagnosing complex faults, investigating underperforming systems, reviewing system design and finding practical ways to improve performance, efficiency and reliability.
If you enjoy getting to the root of a problem and understanding why a system isn't working as it should, this could be the role for you.
The Renewable Heating Service Engineer Role
Servicing, commissioning and maintaining air source heat pump systems
Diagnosing complex heating, hot water, controls and heat pump faults
Identifying issues with installation, design, commissioning and controls
Optimising systems for performance and efficiency
Carrying out plumbing, heating and remedial works
Reviewing flow rates, temperatures, pressures and hydraulic performance
Configuring and troubleshooting weather compensation and advanced controls
Carrying out technical audits and system assessments
Producing clear technical reports and remedial recommendations
Working with clients, manufacturers and contractors to resolve technical issues
Supporting and mentoring less experienced engineers
You'll also assess heat loss, heat pump sizing, emitter outputs, pipe sizing and hydraulic arrangements, ensuring existing installations meet performance requirements and relevant MCS, Building Regulations and manufacturer standards.
About You
You'll have at least 5 years' experience in renewable heating, ideally with significant air source heat pump experience.
We're looking for someone with:
Strong heat pump servicing, commissioning and fault-finding experience
Excellent knowledge of hydronic heating systems and controls
Experience with multiple heat pump manufacturers
Experience carrying out or reviewing heat loss calculations
Good understanding of emitter sizing, flow rates, pipe sizing and system design
Knowledge of weather compensation, zoning, buffers and volumisers
Working knowledge of MCS requirements and Building Regulations
A logical and methodical approach to fault finding
The confidence to support less experienced engineers
A full UK driving licence
Relevant qualifications such as NVQ Plumbing & Heating, Level 3 Air Source Heat Pump, G3, F-Gas or electrical qualifications are beneficial, although additional training can be provided.
What's On Offer?
£40,000–£45,000 salary DOE
Company van and phone
Discretionary performance bonus
25 days' holiday + bank holidays
Company pension and sick pay
Funded manufacturer and technical training
Genuine technical progression
Varied work across multiple manufacturers and system types
