The Georgian House
The challenge
The Georgian House Hotel is a collection of historic buildings brought together into a beautiful boutique hotel. Located centrally within London, they provide a launchpad to all that the city provides. The hotel offers a unique and authentic experience to their guests and the owners are keen to engage with renewable technology to provide environmental benefits and to reduce the operating cost of the hotel.
As a historic building that has evolved over time, the property operates on a combination of gas boilers, which are tucked away in basements and broom cupboards to provide heating and hot water facilities. The client’s current annual spend on heating and hot water was in the region of £40,000 which represented a significant cost and effect on operational expense.
In line with their sustainability and cost reduction targets, they were keen to explore OH4 Energy Saving Technology (OH4) as a potential solution that didn’t require extensive investment in new equipment.
Our solution
After a short site visit, it was agreed that OH4 be installed at the premises with a guarantee that the installation cost would not exceed the year one saving. With no need for any downtime on the heating and hot water system, and access only required in the plant rooms, it was shown that there would be no disruption to hotel operations.
OH4 was fitted in the 5 plant rooms on 3 30KW boilers, a 100KW boiler and a 60KW boiler two additional 30KW boilers were fitted in apartments serviced by the hotel but located away from the main site. The installation took place in October 2024 taking a total of 3 hours.
The results
Based on the data collected between October 2024 and January 2025 the hotel has seen a reduction in KWh per degree day per guest of 23%, representing a projected saving of £9,200 over a year. However, in addition to this, the hotel has opened additional rooms and has seen a significant increase in guest numbers. Taking this into account, the savings are 27% and £10,800 respectively.
