Devon Chamber of Commerce
The challenge
The Devon Chamber of Commerce offices in Plymouth are housed in a late 20th-century single-storey building, heated and supplied with hot water by a 60kW gas boiler connected to radiators and a hot water tank.
Prior to the installation of OH4, the Chamber’s annual gas consumption was 30,952 kWh, costing £2,600 per year and producing 5.6 tonnes of carbon emissions.
As part of their commitment to sustainability and their wider net zero strategy, the Chamber were keen to find a cost-effective way to reduce both energy usage and carbon output without needing to replace their existing boiler system.
Our solution
Following a short visit, the installation of OH4 Energy Saving Technology was recommended.
- OH4 was installed in the plant room at a cost of £700 + VAT
- The installation required no downtime and was completed in just one hour
- No disruption was caused to staff or operations, as only plant room access was needed
An energy savings guarantee was also provided: the Chamber were assured that OH4 would deliver at least a 10% saving on heating costs compared to the previous year.
The results
Since installation in April 2024, energy data has been closely monitored using monthly meter readings adjusted for degree days to account for weather variations.
- 21% reduction in kWh per degree day
- £546 annual saving on heating costs
- Return on investment of 66.85%
- 1.175 tonnes of carbon saved each year
“With our strategic priorities being People, Purpose and Planet, we were excited when OH4 Heating joined the Chamber of Commerce and showed us Steve’s energy and cost savings solution. Perfect in its simplicity, effectiveness and accessibility to all, both in a business and residential setting. They have been great to work with, giving regular updates on outcomes and is quick to respond. We have been delighted with the savings to date. Not only does a reduction in costs mean we can invest that money back in our members, but it is also helping to reduce our energy usage and footprint on the planet.” — Clare Baker, Devon & Plymouth Chamber of Commerce
