Business Details
Trusted HVAC and CHP Solutions in Bristol
Helec Limited is an independent HVAC business with over 17 years of experience supplying energy systems to support commercial building projects by utilising the best proven sustainable, low-carbon, and renewable technologies. Our primary goal is to reduce carbon footprints by delivering practical solutions for producing usable thermal and electrical energy. We specialise in Combined Heat & Power (CHP) packages, complete CHP service and maintenance contracts, supply and delivery of thermal stores and buffer vessels, commercial air source heat pumps, solar thermal hot water systems, and the design and build of large residential district heating systems through single-point energy centre plant room designs. Our full turnkey survey, design, and build service provides complete offsite pre-packaged plant room solutions for onsite installation or externally sited containerised packages.We design effective energy solutions, promoting and providing an extensive range of heating and ventilation systems for commercial and industrial applications, specifying only high-efficiency 'A rated' products that exceed current standards. Our expertise includes renewable and sustainable energy systems such as Combined Heat and Power, Solar Thermal, and Air Source Heat Pumps. We offer a complete range of services from the early design and consultation stage through to installation and performance monitoring, advising on existing schemes to improve efficiency and optimise integration of renewable technologies.

Services
CHP Systems
Our Combined Heat & Power systems integrate electrical power and thermal heat production for onsite use. These gas-fuelled units, including hydrogen-ready models, deliver high efficiency ratings exceeding 85%. We provide full lifecycle support from feasibility studies to installation and maintenance, ensuring optimal performance for commercial and industrial applications.
Heat Pumps
Commercial air source heat pumps provide sustainable heating solutions with outputs from 501600kW. Our systems use natural refrigerants with low global warming potential, delivering stable temperatures up to 75C. We offer hybrid solutions and cascaded configurations for residential and commercial buildings, ensuring compliance with modern energy efficiency standards.
District Heating
We design and implement district heating networks for residential and commercial developments. Our single-point energy centre plant rooms provide centralised heating solutions, reducing operational costs and carbon emissions. Systems include thermal stores, buffer vessels, and intelligent controls for optimal energy distribution across multiple buildings.
Plant Room Design
Our offsite-manufactured plant rooms reduce onsite construction time by 99% pipework assembly. Using CAD drawings and professional indemnity insurance, we create energy-efficient, cost-effective solutions with intelligent controls. Systems include pre-delivery testing and modular GRP enclosures for rapid installation.
ORC Technology
Organic Rankine Cycle systems convert waste thermal heat into additional electrical power. Our Enogia-engineered turbines generate 10180kWe from CHP exhaust heat, biomass boilers, or geothermal sources. This technology maximises energy efficiency by repurposing heat that would otherwise be lost through conventional cooling systems.
Questions
What CHP fuel options do you offer?
We provide natural gas, LPG, biogas, and hydrogen-ready CHP systems ranging from 6kWe to 1mWe, with hydrogen compatibility available on all Energimizer units since 2020.
Do you provide offsite-manufactured plant rooms?
Yes, our EnSmart pre-packaged plant rooms are 99% assembled offsite, reducing onsite hot works and delivery vehicle requirements while maintaining quality assurance through regular build reviews.
Can you integrate heat pumps with existing systems?
We specialise in hybrid heat pump integration with CHP systems, offering cascaded configurations up to 16 units with natural refrigerants for optimal efficiency in retrofit and new build applications.
Do you offer financing options?
Yes, we provide Capex-free Power Purchase Agreements for CHP installations, allowing clients to benefit from low-cost energy without upfront capital investment.
What maintenance services do you provide?
We offer comprehensive CHP and HVAC maintenance contracts with next-day call-out (subject to contract), including performance monitoring and optimisation of existing renewable energy systems.
Do you work with residential developments?
Yes, we've delivered district heating systems for student accommodation, care homes, and residential apartment blocks, including projects at Wembley Hill and Worthing Aquarena beachfront developments.
