 Recommendations also include estimated savings, budget costs, and payback periods for implementing the improvements. The Carbon Trust also advises businesses on eligibility for interest free energy efficiency loans or ECA (Enhanced Capital Allowance) tax relief.
The initial recommendation was to look into alternative fuels and replacement boilers. NJK Partnership suggested switching to liquefied petroleum gas (LPG) for heating and water heating as it is a more energy efficient fuel providing all the flexibility of mains gas in areas where mains gas is unavailable. Compared with oil, LPG burns more cleanly, produces fewer carbon emissions and produces less smoke.
“We were also able to offer the hotel The ThinkTank® telemetry system meaning that the gas level is monitored and Calor is automatically notified when a delivery is due.”
 Three LPG powered Viceroy GT pressure jet boilers from Ideal Boilers were installed in the plant room along with two Lochinvar LPG water heaters. NJK’s Mark Pattison explains the savings that have been made as result of switching to LPG powered equipment: “We looked into the carbon emissions currently being produced by the oil fired boilers and compared it to the estimated emissions from a similar LPG powered system. We identified the potential to save 116 tonnes of CO2 per annum.”
“By introducing the energy efficiency measures at the hotel, primary fuel use reductions of over £6,350 have been estimated per annum. This is due to the move from oil to LPG powered boilers and increased plant efficiency including improved control functions and better pipe insulation.”
“Estimated maintenance costs for the existing steam boilers were running at approximately £25,000 per annum, due to the age of the boiler plant. The new boiler plant has reduced this figure to £5,000 per annum. Finally, the steam boilers suffered water loss during the blowdown procedure, which has now been eliminated, providing further savings.”
Hotel manager Les Thompson concludes: “By implementing NJK’s suggested improvements to reduce our carbon emissions, the hotel has become more energy efficient and therefore resulted in the added benefit of cost savings. NJK has estimated that we will have made enough cost savings to cover the installation of the new equipment in less than six years.”
