1. A method for measuring efficiency improvement in a heating system, said method comprising the steps of:sensing an outflow temperature using a temperature sensor, mounted on a heat outflow of said heating system;recording said temperature and a call time at a thermostat burner call;using a processor to calculate the following relationships:calculating a percentage of a reduction of fuel consumption, that the efficiency improvement saves; anddisplaying the percentage saved on a readout;where the calculating is by the following formula:% Savings=(RTn−RTx)/RTn Where: RTn=(K/(T0+T3))*(T3)RTx=(K/(T0+T1+T2+T3))*(T2+T3−PP)RTn=Extrapolated total burner run-time for the pseudo original burner cycleRTx=Extrapolated total burner run-time for the actual burner cycleK=constant used to normalize the data+3600PP=pre-purge timeT0 is time from burner shutdown to Thermostat call,T1 is Intellicon-induced delay of boiler firing timeT2 is time from post delay unit call to the Recorded temperature at a thermostsat burner callT3 is the period during a burner run from the Recorded temperature to burner shut-off. 2. The method according to claim 1 where the equation for calculating an average (Average Savings) of an accumulated percentage of Savings (% Savings) calculations is as follows:Average Savings=((Asav*(Ctotal−1))+Isav)/Ctotal where:Asav=Average Savings=Total of all Isav, divided by (Ctotal−1)Isav=value calculated from % Savings equationCtotal=accumulated number of cycles incremented by 1 at the end of T3 (Ctotal=Ctotal+1). 3. A method for measuring efficiency improvement in a heating system, according to claim 1, where:the heating system is hydronic. 4. A method for measuring efficiency improvement in a heating system, according to claim 3, wherein the calculating is by the following formula:% Savings=(RTn−RTx)/RTn Where: RTn=(K/(T0+T3))*(T3)RTx=(K/(T0+T1+T2+T3))*(T2+T3−PP)RTn=Extrapolated total burner run-time for the pseudo original burner cycleRTx=Extrapolated total burner run-time for the actual burner cycleK=constant used to normalize the data+3600PP=pre-purge time. 5. A method for measuring efficiency improvement in a heating system, according to claim 4, where a there is an equation for calculating an average (Average Savings) of the accumulated percentage of Savings (% Savings), calculated as follows:Average Savings=((Asav*(Ctotal−1))+Isav)/Ctotal where:Asav=Average Savings=Total of all Isav divided by (Ctotal−1)Isav=value calculated from % Savings equationCtotal=accumulated number of cycles incremented by 1 at the end of T3 (Ctotal=Ctotal+1). 6. A method for measuring efficiency improvement in a heating system, according to claim 1 where:the heating system is hydronic; andthe percentage of a reduction of fuel consumption is an average savings. 7. A method for measuring efficiency improvement in a heating system, according to claim 6, where the calculating of the average (Average Savings) is as follows:Average Savings=((Asav*(Ctotal−1))+Isav)/Ctotal where:Asav=Average Savings=Total of all Isav divided by (Ctotal−1)Isav=value calculated from % Savings equationCtotal=accumulated number of cycles incremented by 1 at the end of T3 (Ctotal=Ctotal+1). 8. The method according claim 3 where there is a further calculation of average savings, and a display of such average savings. 9. A method for measuring efficiency improvement in a heating system, said method comprising the steps of:sensing an outflow temperature using a temperature sensor, mounted on a heat outflow of said heating system;recording said temperature and a call time at a thermostat burner call;using a processor to calculate the following relationships:calculating a percentage of a reduction of fuel consumption, that the efficiency improvement saves; anddisplaying the percentage saved on a readout;where the equation for calculating an average (Average Savings) of an accumulated percentage of Savings (% Savings) calculations is as follows:Average Savings=((Asav*(Ctotal−1))+Isav)/Ctotal where:Asav=Average Savings=Total of all Isav divided by (Ctotal−1)Isav=value calculated from % Savings equationCtotal=accumulated number of cycles incremented by 1 at the end of T3 (Ctotal=Ctotal+1)T3 is the period during a burner run from the Recorded temperature to burner shut-off.
