Cornwall Hotel & Spa

The challenge

The Cornwall Hotel & Spa is an iconic Cornwall Hotel with a strong local history and is well renowned for its luxurious accommodation, food and spa facilities. The hotel operators are highly respected in the hospitality sector for their forward-thinking approach to environmental sustainability and are aiming to be the net zero holiday destination of choice.

Our solution

After initial consultations, it was agreed that OH4 be installed at the premises with a guarantee that the installation cost would not exceed the first year’s saving.

With the hotel enjoying a constant flow of guests and visitors, it was business critical that the installation of OH4 did not have an impact on the hotel and spa operations. With the unique nature of OH4 and the fact that the hotel did not have to turn off their heating system, the installation was seamless and had no impact on the hotel or its guests and visitors.

In addition to the main hotel building, it has been agreed that OH4 will work around lettings for the smaller installations to the 20 separate holiday cottages with 20 installations fitted in May 2024 and hot tubs fitted with OH4 in July 2024.

The results

The savings achieved on a KWh per degree day per guest basis in the 6 months since fitting OH4 is 12.61% representing a saving of £5,359.25 in the 6-month period. However, we later identified that their pool had been set to a higher temperature, increasing their gas usage. If we factor in the increase in temperature on the pool the actual savings are over 29%, and representing a saving of £12,325 in 6 months, making the estimated annual saving £24,750. 

Under our current charging model this would be charged at £17,000 payable £708.33 per month for 12 months and £354.17 per month for a further 24 months based on a projected saving of 20%.
