commercial high efficiency - Laars
®
VARI-PRIME TM Control Technology Laars VARI-PRIMETM flow control matches the modulation rate of a MagnaTherm’s combustion system to the rate of a variable speed boiler pump. This unique on board control allows the MagnaTherm boiler to mirror the heating system’s profile during varying load conditions and optimize overall efficiency.
COMMERCIAL HIGH EFFICIENCY
Boiler pumps are typically sized for the maximum flow that a boiler needs, but boilers rarely operate at maximum capacity. A pump’s power consumption can drop by as much as 50% with only a 20% reduction in speed. By replacing a boiler’s typical on/off pump with a VARI-PRIMETM equipped MagnaTherm control and variable speed pump, over a thousand dollars in boiler pump watt usage can be saved per year. The payback for the variable speed pump setup can be realized in as little as one year!
Condensing Boiler and Volume Water Heater
The combined potential energy savings of the MagnaTherm’s high efficiency combustion coupled with the VARI-PRIMETM control system is huge. Only the Laars MagnaTherm with built in VARI-PRIMETM controls can offer such savings in one package!

A Three Million BTU/hr MagnaTherm using VARI-PRIMETM pump control and a Goulds 22SH variable speed boiler pump were used in this example. *2013 US Average of 11 cents per kWH used, source US Energy Information Administration. See Laars VARI-PRIMETM white paper 9185 for complete details.
Lead Lag Cascading of up to 8 MagnaTherms The advanced MagnaTherm control system also includes a cascading feature that allows for up to eight units to be lead lagged together. This results in a modulating heating cell of up to 32 million BTU/hr with a combined 40:1 turndown. Also included is an auto rotation function that periodically changes lead boiler to evenly spread service between all boilers. Communication with Building Automation Systems happens seamlessly via a built-in Modbus protocol included with all MagnaTherm boilers. The Laars Gateway is available for use with BacNET and LON networks.

A Perfect Balance of Size, Form and Function Every commercial heating system is unique and as such requires a boiler that can respond to system fluctuations, while maintaining the energy conservation standards held by today’s building owners. Such a boiler now exists in the innovative Laars MagnaTherm.
A multi-color, simple to use smart touch screen display allows you to fully control and setup the MagnaTherm.
On board every boiler is MagnaTherm’s unique VARI-PRIMETM control that allows building owners to save thousands of dollars over the life of the boiler due to dramatically reduced energy costs versus a typical on/off pump arrangement. Only the Laars MagnaTherm includes the VARI-PRIMETM control that balances combustion, air flow and water flow on every boiler! The MagnaTherm’s small footprint, slim vertical design and removable top section help it to fit into tight mechanical rooms. It’s optional electrical packages allow for easy pairing with various field supply voltages. And the large easy-to-navigate color touch screen display results in quick setup and diagnostics and allows up to 8 MagnaTherms to be controlled in a cascading boiler bank.

CONDENSING BOILER & VOLUME WATER HEATER
A Perfect Balance of Size, Form and Function Every commercial heating system is unique and as such requires a boiler that can respond to system fluctuations, while maintaining the energy conservation standards held by today’s building owners. Such a boiler now exists in the innovative Laars MagnaTherm. On board every boiler is MagnaTherm’s unique VARI-PRIMETM control that allows building owners to save thousands of dollars over the life of the boiler due to dramatically reduced energy costs versus a typical on/off pump arrangement. Only the Laars MagnaTherm includes the VARI-PRIMETM control that balances combustion, air flow and water flow on every boiler! The MagnaTherm’s small footprint, slim vertical design and removable top section help it to fit into tight mechanical rooms. It’s optional electrical packages allow for easy pairing with various field supply voltages. And the large easy-to-navigate color touch screen display results in quick setup and diagnostics and allows up to 8 MagnaTherms to be controlled in a cascading boiler bank.

CONDENSING BOILER & VOLUME WATER HEATER
A Perfect Balance of Size, Form and Function Every commercial heating system is unique and as such requires a boiler that can respond to system fluctuations, while maintaining the energy conservation standards held by today’s building owners. Such a boiler now exists in the innovative Laars MagnaTherm. On board every boiler is MagnaTherm’s unique VARI-PRIMETM control that allows building owners to save thousands of dollars over the life of the boiler due to dramatically reduced energy costs versus a typical on/off pump arrangement. Only the Laars MagnaTherm includes the VARI-PRIMETM control that balances combustion, air flow and water flow on every boiler! The MagnaTherm’s small footprint, slim vertical design and removable top section help it to fit into tight mechanical rooms. It’s optional electrical packages allow for easy pairing with various field supply voltages. And the large easy-to-navigate color touch screen display results in quick setup and diagnostics and allows up to 8 MagnaTherms to be controlled in a cascading boiler bank.

VARI-PRIME TM Control Technology Laars VARI-PRIMETM flow control matches the modulation rate of a MagnaTherm’s combustion system to the rate of a variable speed boiler pump. This unique on board control allows the MagnaTherm boiler to mirror the heating system’s profile during varying load conditions and optimize overall efficiency.
COMMERCIAL HIGH EFFICIENCY
Boiler pumps are typically sized for the maximum flow that a boiler needs, but boilers rarely operate at maximum capacity. A pump’s power consumption can drop by as much as 50% with only a 20% reduction in speed. By replacing a boiler’s typical on/off pump with a VARI-PRIMETM equipped MagnaTherm control and variable speed pump, over a thousand dollars in boiler pump watt usage can be saved per year. The payback for the variable speed pump setup can be realized in as little as one year!
Condensing Boiler and Volume Water Heater
The combined potential energy savings of the MagnaTherm’s high efficiency combustion coupled with the VARI-PRIMETM control system is huge. Only the Laars MagnaTherm with built in VARI-PRIMETM controls can offer such savings in one package!

Lead Lag Cascading of up to 8 MagnaTherms HLW
The advanced MagnaTherm control system also includes a cascading feature that allows for up to eight units to be lead lagged together. This results in a modulating heating cell of up to 32 million BTU/hr with a combined 40:1 turndown. Also included is an auto rotation function that periodically changes lead boiler to evenly spread service between all boilers. Communication with Building Automation Systems happens seamlessly via a built-in Modbus protocol included with all MagnaTherm boilers.

CONDENSING BOILER & VOLUME WATER HEATER
A Perfect Balance of Size, Form and Function Every commercial heating system is unique and as such requires a boiler that can respond to system fluctuations, while maintaining the energy conservation standards held by today’s building owners. Such a boiler now exists in the innovative Laars MagnaTherm. On board every boiler is MagnaTherm’s unique VARI-PRIMETM control that allows building owners to save thousands of dollars over the life of the boiler due to dramatically reduced energy costs versus a typical on/off pump arrangement. Only the Laars MagnaTherm includes the VARI-PRIMETM control that balances combustion, air flow and water flow on every boiler! The MagnaTherm’s small footprint, slim vertical design and removable top section help it to fit into tight mechanical rooms. It’s optional electrical packages allow for easy pairing with various field supply voltages. And the large easy-to-navigate color touch screen display results in quick setup and diagnostics and allows up to 8 MagnaTherms to be controlled in a cascading boiler bank.

CONDENSING BOILER & VOLUME WATER HEATER
A Perfect Balance of Size, Form and Function Every commercial heating system is unique and as such requires a boiler that can respond to system fluctuations, while maintaining the energy conservation standards held by today’s building owners. Such a boiler now exists in the innovative Laars MagnaTherm. On board every boiler is MagnaTherm’s unique VARI-PRIMETM control that allows building owners to save thousands of dollars over the life of the boiler due to dramatically reduced energy costs versus a typical on/off pump arrangement. Only the Laars MagnaTherm includes the VARI-PRIMETM control that balances combustion, air flow and water flow on every boiler! The MagnaTherm’s small footprint, slim vertical design and removable top section help it to fit into tight mechanical rooms. It’s optional electrical packages allow for easy pairing with various field supply voltages. And the large easy-to-navigate color touch screen display results in quick setup and diagnostics and allows up to 8 MagnaTherms to be controlled in a cascading boiler bank.

VARI-PRIME TM Control Technology Laars VARI-PRIMETM flow control matches the modulation rate of a MagnaTherm’s combustion system to the rate of a variable speed boiler pump. This unique on board control allows the MagnaTherm boiler to mirror the heating system’s profile during varying load conditions and optimize overall efficiency.
COMMERCIAL HIGH EFFICIENCY
Boiler pumps are typically sized for the maximum flow that a boiler needs, but boilers rarely operate at maximum capacity. A pump’s power consumption can drop by as much as 50% with only a 20% reduction in speed. By replacing a boiler’s typical on/off pump with a VARI-PRIMETM equipped MagnaTherm control and variable speed pump, over a thousand dollars in boiler pump watt usage can be saved per year. The payback for the variable speed pump setup can be realized in as little as one year!
Condensing Boiler and Volume Water Heater
The combined potential energy savings of the MagnaTherm’s high efficiency combustion coupled with the VARI-PRIMETM control system is huge. Only the Laars MagnaTherm with built in VARI-PRIMETM controls can offer such savings in one package!

The advanced MagnaTherm control system also includes a cascading feature that allows for up to eight units to be lead lagged together. This results in a modulating heating cell of up to 32 million BTU/hr with a combined 40:1 turndown. Also included is an auto rotation function that periodically changes lead boiler to evenly spread service between all boilers. Communication with Building Automation Systems happens seamlessly via a built-in Modbus protocol included with all MagnaTherm boilers.
