Helec delivers immediate savings of around 30% on Tewkesbury Park’s heating bills
With future savings estimated at circa £75k (electricity) and £150k (heating) per year
ISSUE:
Their energy bills were set to increase four-fold.
SOLUTION:
Helec provided a turnkey solution to;
Switch the site fuel away from oil to Calor LPG,
Replace the old boilers with new Strebel S-FX320 modulating boilers,
Supply & commission two combined heat and power units (CHP),
Replace the existing fixed speed pumps with intelligent modulating Grundfos Magna 3 pumps,
Provide thermal stores and a tailored BMS system to monitor and control the energy distribution throughout the hotel services
– all without causing disruption to the hotel.
RESULTS:
Immediate savings of 30% on heating bills, further electricity savings from the CHP’s onsite power generation along with reduced carbon emissions and improved environmental credibility for Tewksbury Park.

At the height of the energy crisis, Tewkesbury Park (a 93-room hotel & Spa with an 18-hole golf course) found their combined energy bills set to increase four-fold.
Chris McIntosh, Director had read about CHP and wanted to see if this could be the answer to reducing their power costs while bringing stability to their existing supply. Chris contacted the Helec team, who attended to review the hotels energy systems and see what could be done.
Initial Assessment and Site Visit by Helec:
Our initial site visit revealed the hotels existing boilers were old and inefficient and suggested replacing these would show an immediate saving of around 30% on their heating bills.
Taking into consideration the hotels need to not only save money but also reduce carbon emissions, Helec recommended the use of gas instead of the existing oil supply. Natural gas was unavailable, so LPG was chosen.
Heat pumps were considered but were deemed not suitable for the hotel’s immediate needs on this occasion.
Analysing their plant room also revealed that their existing boilers were no longer performing optimally and were fuelled by an expensive oil-based fuel source where we would use LPG.
This meant that Tewkesbury Park were spending more money than necessary to keep their water hot. By replacing this equipment, the hotel would immediately see benefits, providing instant savings on fuel costs.
Project Planning and Collaboration:
Working closely with Tewkesbury Park, we created a detailed project plan– encompassing civil works, plumbing upgrades, and the installation of the CHP units.
It was vital that any works carried out did not disrupt the normal day to day operation of the Hotel and Spa. The planning was carefully prepared to work with the hotels busy schedule and minimise disruptions.
Execution:
This project comprised of three key stages:
Magna 3 District pumps
Stage One
Remove and replace the oil boilers with the new Strebel S-FX320 LPG boilers and connect to the hotel.
Stage Two
Install 6 new Grundfos pumps to feed the newly zoned areas and integrate 3 Galu 2,500 litre thermal stores. These thermal stores enabled a much larger heat output for short periods than the new boilers were capable of alone.
Stage Three
Installation of a BMS system to monitor and control the energy distribution in the hotel. This ensures that the heat is always supplied where it is needed and nowhere else !
LPG Strebel Boilers
The BMS is managed remotely which makes updates and improvements quick and easy.
Installation of 2 new CHP units. The 50kWe CHP will operate almost continuously to satisfy the hotels base load whilst the second unit, a 75kWe unit will top up any shortfall, whilst also offering a standby power facility in the event of grid power cuts.
This setup now provides Tewkesbury Park with absolute energy security. Their remote location meant reliance on the National Grid came with connection issues and the very real possibility of power outages.
Now, with dual CHP engines installed, operations can continue completely unimpeded, should the situation of power cuts arise.
Efficiency Gains and Environmental Impact:
The installation of the CHP units and cleaner, greener high efficiency boilers, marked a significant milestone for Tewkesbury Park, not only in the addressing of their energy cost concerns but also in enhancing overall operational efficiency – helping the hotel reduce its carbon footprint.
Transitioning from oil to LPG gas to run the boilers, alongside the installation of CHP units, has resulted in a substantial reduction in overall operating costs– with the additional bonus of further reducing the environmental impact of the facility.
“One of the most impressive aspects of Helec is how they handle a lot of the work themselves, from planning to implementation they are with you 100% of the way. Our CHP was a fantastic investment and any company would benefit greatly from at least meeting with Helec to get an understanding of what the benefits might be.”
Chris McIntosh, Director of Tewkesbury Park Hotel
Our knowledge, collaborative approach, and innovative solutions were instrumental in transforming Tewkesbury Park’s energy infrastructure.
The successful implementation of CHP technology and associated upgrades not only reduced their energy costs but also secured the hotel’s energy and improved their environmental credentials.
We pride ourselves on our agility and our ability to tailor energy solutions to the specific needs of clients, and it’s this that now has ensured enduring efficiency and sustainability gains for Tewkesbury Park.
