Ways to reduce boiler, steam and process heating costs
1. Implement heat recovery
Heat recovery is a process where you redirect and use heat that would otherwise be vented outside, to preheat the boiler feed water.
Implement condensate recovery, a process where you redirect condensate into your boiler feed water tank.
To get the most out of your boiler, regularly blowdown water using steam pressure to remove any build-up of impurities, which improves the efficiency of the system.
On average, heat recovery will:
- cost less than $70,000 to implement
- save nearly $45,000 annually
- take less than 2 years to pay back
- save nearly 400 tonnes of greenhouse gas emissions annually.
2. Add operational controls and a variable speed drive to your system
Operational controls and variable speed drives work together to make your system more efficient.
Operational controls can switch the system on or off and adjust the temperature according to demand.
A variable speed drive adjusts the speed of combustion air fans and feed water pumps.
On average, adding operational controls and variable speed drive will:
- cost less than $27,000 to implement
- save more than $50,000 annually
- take less than 1.5 years to pay back
- save more than 270 tonnes of greenhouse gas emissions annually.
3. Insulate piping
Insulate steam, hot water and condensate piping to reduce heat loss and improve productivity of the system.
On average, insulating piping will:
- cost less than $16,500 to implement
- save more than $7500 annually
- take 2 years to pay back
- save more than 45 tonnes of greenhouse gas emissions annually.
4. Regular maintenance
Schedule regularly maintenance with a technician to make sure your system is working efficiently.
Regularly check for:
- burner combustion efficiency
- steam leaks
- heat losses
- faulty steam traps.
This can save up to 5% of your energy bill.
On average, annual regular maintenance will:
- cost less than $23,500
- save more than $51,500
- take less than 1 year to pay back
- save more than 270 tonnes of greenhouse gas emissions.
5. Measure and assess the performance of your system
Install electricity and gas meters to your boiler, steam and process heating system to monitor use.
The metre can show you how much energy the system uses and when. This data can be analysed to see if it’s working efficiently or when it’s not.
An operations manager will be able to analyse the data for you. If you don’t have an operations manager, call a technician.
On average, measuring, analysing and updating the system will:
- cost less than $50,000
- save more than $18,000 annually
- take less than 3 years to pay back
- save more than 160 tonnes of greenhouse gas emissions annually.
