FAQs

What types of organisations does GS Renewable typically work with?

We work with large-scale commercial and industrial organisations including manufacturing, pharmaceuticals, food and beverage, hotels, healthcare, logistics and public sector, estates and luxury domestic. Our systems are designed for mission-critical environments where uptime, performance and regulatory compliance are essential.

What problems do heat pumps solve for large organisations?

Heat pumps enable organisations to:

Reduce dependence on gas and fossil fuels
Lower energy costs and exposure to price volatility
Decarbonise heat for space, hot water and process loads
Improve ESG performance and regulatory compliance
Future-proof energy infrastructure

They are a core technology for long-term energy transition strategies.

Are heat pumps suitable for industrial process heat?

Yes. Modern industrial heat pumps systems can supply from low to high temperatures that can be deployed for:

Process hot water
Washdown and CIP
Pre-heating for steam systems
Space heating for large facilities
High temperature process applications

We design hybrid architectures where required to support higher temperature demands.

What is the typical return on investment for an industrial heat pump system?

ROI varies by application, energy profile and existing infrastructure. Typical projects deliver:

Significant carbon and EU ETS cost savings
Strong long-term lifecycle returns over 20+ years

We provide full CAPEX, OPEX and payback modelling as part of every project.

How do heat pumps compare financially to gas boilers?

Heat pumps typically:

Deliver 3–5x more heat energy than the electricity they consume
Reduce operating costs when paired with renewable electricity
Avoid future carbon taxes and fuel volatility
Lower long-term maintenance and replacement costs

Over the asset lifecycle, heat pumps consistently outperform fossil fuel systems on total cost of ownership.

What grants and funding supports are available?

We support clients with:

SEAI grant applications
Public sector decarbonisation funding
Energy efficiency schemes
Green finance and sustainability-linked lending

We integrate all available funding into the project business case.

How is a heat pump system designed for an industrial facility?

Our engineering process includes:

Thermal load and profile analysis
Temperature and flow regime modelling
Electrical capacity and infrastructure assessment
Plant room space and layout design
Controls and BMS integration
Redundancy and resilience engineering

The result is a fully engineered, site-specific solution.

Can heat pumps integrate with existing boilers, CHP or steam systems?

Yes. Most projects use hybrid architectures where heat pumps:

Preheat boiler or steam systems
Recover waste heat
Displace base-load fossil fuel consumption
Operate alongside existing infrastructure

This allows phased decarbonisation without operational risk.

What is a modular heat pump plant room?

A modular plant room is a factory-built, fully assembled energy centre that includes:

Heat pumps
Pumps, buffers and hydraulics
Electrical and control panels
Safety and monitoring systems

It is delivered to site as a complete unit, reducing programme risk, installation time and disruption.

What level of redundancy is built into the system?

All systems are designed to meet critical infrastructure standards and can include:

N+1 redundancy
Duty/standby configurations
Multi-unit cascades
Load-sharing controls

In retrofit scenarios existing fossil fuel fed boilers can be retained and integrated into the system to provide cost effective emergency backup.

This ensures high availability and operational resilience.

How long does a typical project take?

Timelines vary by scale and complexity, but typically:

Design & approvals: 8–16 weeks
Plant room manufacture: 8–12 weeks
Site installation: 2–6 weeks
Commissioning: 2–4 weeks

Modular delivery significantly reduces on-site construction time.

Can installation be completed without disrupting operations?

Yes. Our modular approach and phased integration methodology allows installation in live environments with minimal downtime.

We plan commissioning around operational windows and production schedules.

How do heat pumps support ESG and decarbonisation targets?

Heat pumps:

Eliminate or reduce Scope 1 emissions
Enable electrification of heat
Support Science Based Targets
Improve CSRD and sustainability reporting
Reduce exposure to EU ETS carbon costs

They are a cornerstone of credible net-zero strategies.

Are systems compliant with EU and Irish regulations?

Yes. All systems are designed in accordance with:

Irish and EU building regulations
Energy performance standards
Safety and pressure systems directives
Electrical and mechanical codes
Environmental compliance requirements

What is the expected lifespan of an industrial heat pump system?

Our systems are designed as long-term infrastructure assets with:

Modular replaceable components
Serviceable architecture
Upgrade-ready controls

This ensures predictable performance and long-term ROI.

What maintenance is required?

We provide:

Planned preventative maintenance
Remote monitoring and diagnostics
Performance optimisation
Emergency support
Operator training

This protects uptime, efficiency and asset value.

Who operates the system after handover?

Your facilities team operates the system day-to-day. We provide:

Full training
O&M documentation
Performance dashboards
Ongoing engineering support

We remain a long-term technical partner.

How do we know the system will perform as designed?
