Business Details
Renewable Heating System Design & Maintenance Experts
Eco Engineering has been specialising in the design of energy-efficient heating systems incorporating renewable technologies for over two decades. Our expertise lies in integrating heat pumps, solar PV, solar thermal, and biomass solutions to significantly reduce running costs and fossil fuel reliance while maintaining comfort. We collaborate with architects, self-builders, and homeowners to deliver fully integrated heating systems, supported by detailed design specifications and future running cost analyses. Our team holds HETAS-approved biomass maintenance certification and has extensive experience in system optimisation and problem diagnosis.

We prioritise innovation, as demonstrated by our use of PVT panels connected to ground source heat pumps and battery storage systems. Our services include heat loss surveys, feasibility studies, and detailed design packages tailored to new builds and renovation projects. We ensure compliance with MCS standards for Boiler Upgrade Scheme grants and provide commissioning support for self-installed systems. Our approach combines technical precision with sustainability, aiming to create low-carbon heating solutions that align with evolving energy tariffs and environmental goals.

Services
Heat Loss Survey
Our heat loss surveys calculate energy escape through building elements to determine optimal heating system sizing. Using MCS-compliant methodology, we produce room-by-room analyses that inform radiator sizing and insulation requirements. This essential step ensures system efficiency and eligibility for Boiler Upgrade Scheme grants.
Feasibility Study
We conduct detailed feasibility studies using simulation software to evaluate renewable energy combinations for your property. Our analysis compares different technologies against fossil fuel benchmarks, providing clear insights into initial costs, running expenses, and CO2 savings for informed decision-making.
Biomass Systems
We design and maintain biomass boiler systems using wood pellets or chips for high-efficiency heating. Our solutions include automated pellet boilers suitable for domestic properties and large-scale chip systems for commercial venues, complete with weather-compensated controls to reduce annual fuel costs by up to 15%.
Solar Thermal
Our solar thermal installations reduce conventional fuel usage by integrating with biomass boilers or heat pumps. Systems are designed to maximise solar gains through optimised thermal store sizing, requiring minimal maintenance with solar liquid checks only needed every five years.
Heat Pump Installation
We specify and install air and ground source heat pumps with 3:1 efficiency ratios, where 1kW electricity generates 3kW thermal energy. Our designs incorporate innovative control systems that optimise performance with solar PV arrays and battery storage for net-zero energy buildings.
Questions
What is a heat loss survey and why is it important?
A heat loss survey calculates energy escape through walls, floors, and windows to determine correct boiler sizing. It's essential for MCS grant eligibility and system efficiency.
How do feasibility studies benefit renewable energy projects?
Feasibility studies use energy modelling to compare renewable options against fossil fuels, providing clear data on costs, savings, and CO2 reduction to guide investment decisions.
Are biomass boilers suitable for domestic properties?
Yes, modern pellet boilers operate quietly and efficiently, making them ideal for homes. They require weekly pellet top-ups in winter and integrate with existing radiator systems.
Can solar thermal systems work year-round?
Solar thermal systems generate hot water year-round, with seasonal variations. Summer output can reduce wood fuel usage by up to 60% when combined with timed boiler operation.
Do you provide maintenance for existing renewable systems?
Yes, our HETAS-approved maintenance services optimise system efficiency, including biomass boiler servicing and heat pump performance checks to maintain RHI compliance.
What areas do you cover for installations?
We operate nationwide but focus on Gloucestershire, South Coast, Bath, Chichester, and Cotswold regions, with remote design support available for self-build projects elsewhere.
