Boiler Upgrades that Pay Off
We offer automated systems that can reduce oil/gas consumption by up to 35%, eliminate 90% of maintenance headaches, significantly reduce emissions and pay for themselves in as little as one year.
These improvements are possible when transitioning away from older linkage systems and antiquated burners to modern systems. However, even fairly modern installations can often see significant fuel and emissions improvements with our upgrades.

Featured Product: Autoflame Touchscreen Boiler Controls
Autoflame gives users a wide variety of controls and reporting features for their boilerhouse.
One Source Engineering has a number of these installations in the field, and can bring you and your team on-site to see them in action.
TDS/Top Blowdown
System drains water near the surface based on TDS (Total Dissolved Solids) readings from a probe. It continues to drain water (which is then refilled by a feedwater valve) until the probe determines that the water has reached prescribed TDS levels. The engineer can also choose to set Top Blowdown at timed intervals instead.

VSD Control
Control fan motor speed for greater efficiency
Water Level Control
System safety is guaranteed as water level measurement is managed by two identical capacitance probes, both of which measure and control to the level switching points entered at the time of commissioning. The probes support up to 7 switch points (High level, 1st Low Level, 2nd Low Level, etc). The points trigger feedwater activation, alarms or lockouts, depending on commissioning.
Bottom Blowdown
Prevents sludge buildup at the bottom of the boiler by rapidly draining water at prescribed intervals.
Steam Flow Metering
Adding steam or heat flow metering to a Mk7 with expansion board is as simple as optioning it in. Additional sensors increase accuracy. Once enabled, user has access to:
• Instantaneous steam & heat flow
• Gross/Net heat flow in the boiler calculated & displayed
• 24 hours of logged heat flow stored internally
• 2 years of heat flow data available on the Mk7 DTI
• Online analysis including instantaneous/totalised values, data logging & graphical display on the MM Controller & DTI
• Displayed in lbs/hr or kgs/hr
Dual Fuel
The current unit is configured for both oil (red line) and natural gas (yellow line - currently active) fuel operation. If this were configured for single fuel, one of these lines would not be visible.
EGA: Total Emissions & Fuel Costs

Featured Product: Limpsfield Burners
Limpsfield industrial burners are guaranteed with 3% O2 emissions when firing gas, while producing negligible CO, and with a maximized efficiency.
Upgrading your boiler to a Limpsfield burner could save up to 15% on your annual fuel bill.
