Intelligent

The M2G is an advanced intelligent boiler optimisation control that optimises the efficiency of each individual boiler. A unit attached to each boiler monitors the temperature of the water in the flow and return every 10 seconds and the information is recorded, along with the heat transfer rates at both the first and second stage firings.

When a loading demand is made, the M2G system automatically checks the latest data it has stored and decides whether it is more economical to retain first stage firing or to introduce a second stage firing. The result is a substantial fuel reduction during less demanding situations while ensuring maximum capacity during heavy load periods. A UK and European patent is pending.

The M2G is not to be mistaken with a time delay unit. The M2G uses self learning intelligence when deciding if and when a boiler should fire and for how long it should fire. Time delay units on the other hand will stop the burner from firing even when there is a real demand from the building for heat. The timer adds additional control but not additional intelligence to the system and comfort levels in the building will be negatively affected.

How does it work?

By measuring the boiler system demand / load via two digital temperature sensors on the flow and return pipe work and by the adaptive algorithms the M2G will measure and calculate the boiler load profile, this will in turn inhibit the burner firing cycle based on the temperature gradient over time. This will ensure that the boiler does not fire unnecessarily for light load conditions or conditions of standing losses from the boiler. Thus saving energy and maximising boiler efficiency at all times.

Flexible

The M2G system is designed to be used in a wide variety of commercial applications that consume natural gas, LP gas, Class C oil or Class D oil. Although designed for multiple boilers, it can also be used singly and can be fitted to many types of boiler including forced draught and atmospheric systems.

Installation

With an average installation time of just 90 minutes for each boiler, and with no disruption to the heating system during installation, savings can be achieved from day one.

Easily and quickly installed with no readjustment or calibration required throughout the lifetime of the M2G system.

The M2G interface/interlocks in the following way:

a) Your boiler(s),

The M2G is wired in series with the existing boiler thermostat circuit, ensuring that existing boiler thermostat set point (temperature) is always maintained and controlled. In all cases, the primary safety controls of the burner/boiler are not compromised or interrupted.

b) Your BMS (Building Management System)

The M2G system can be interfaced with all types of BMS/ BEMS strategies and is non-intrusive to the building’s controls and preset comfort levels.

c) Your existing boiler house controls:

The M2G will work with and complement existing controls such as: Weather Compensation, Heating Optimisers Controls and Boiler Sequencing Controls.

M2G digital temperature sensors installation:

The M2G measures the boiler flow and return temperatures individually on each boilers, these are a surface mount method that is completely non intrusive to the system pipe work. The sensors are fixed mechanically and does not require system “drain down”.
