Our Projects

As part of a full restoration of a beautiful London townhouse, The Big Heat Pump Company delivered a flawless installation of stylish new radiators that perfectly complement the fresh interior design. Blending form and function, the radiators not only provide efficient heating but also enhance each room with their sleek, modern look. The team’s expert workmanship is evident throughout, with clean pipework and thoughtful placement that harmonises effortlessly with the home's aesthetic. Alongside the radiators, The Big Heat Pump Company also installed an air source heat pump, bringing sustainable, low-carbon heating to this elegant period property.

Cambridge House – A Complete Renewable Revamp Cambridge House underwent a full renewable energy overhaul, featuring the OCHSNER Air 18 heat pump, known for its super-quiet operation and exceptional efficiency. Perfectly suited for this energy-conscious homeowner with discerning taste, the OCHSNER system was an ideal choice. The project also included advanced features like cork insulation and Tesla battery storage, ensuring the home is well-equipped to handle future energy price increases and changing climate conditions. This forward-thinking upgrade provides both comfort and long-term sustainability.

We design and build containerised plant rooms in any size, colour or cladding options. These are perfect for commercial use. In this example two containerised plant rooms are being used as plant rooms that house the OCHSNER heat pumps and the external fan units are placed on a single gantry on top. The external space was previously unused and this solution meant that all the new refurbishment work could be done outside and not disturb the leisure centre day to day operation, nor did they have to find the space in the existing undersized plant room

St Peter Mancroft Church in Norwich city centre has dramatically reduced its carbon footprint and energy use by replacing its entire interior lighting system, installing OCHSNER heat pumps as well as batteries and solar panels. Through this work, the church expects to see an 84% reduction in emissions by saving 60 tonnes of CO2 each year.​ St Peter Mancroft is now recognised by The Church of England as a Demonstrator Church as an example for all churches striving to meet the CofE's Net Zero 2030 ambition

We helped decarbonise St Josephs School by replacing the old failing gas boiler with a new energy efficient OCHSNER Air 41 heat pump. Helping them reduce their bills at the same time. The school already had a large Solar PV array and voltage optimiser installed that complemented the changeover to a heat pump heat solution

Hard to heat farmhouse in Wales becomes warm and cosy with an OCHSNER Air Hawk 518 heat pump. When sitting in their conservatory or out on their patio, the clients can't hear the outdoor fan unit at all, the sounds of nature surrounding the house are all louder

A Georgian farmhouse with lots of original features including single pane sash windows and open fires. This is a classic hard to heat building in the UK. Two OCHSNER air source heat pumps provide all the heating and hot water requirements with the existing oil kept as a backup. This was done with the existing plumbing and radiators. The current inhabitants have never been warmer and can't believe how long they lived in the cold before they changed over to OCHSNER heat pumps.

A full property refurbishment in London with large basement conversion, the OCHSNER air source heat pump provides all the space heating and hot water to the UFH throughout the dwelling. The new solar panels, battery storage and electric car charger brought the whole system together so the customer can future proof their energy bills as well as dramatically reducing their CO2 emissions. Even in central london with precious garden space and close proximity neighbours, the sound levels are so low that the evaporator easily passed planning restrictions and the external fan unit a feature of the garden
