so im on the right line then from website
Using this advanced technology almost all heat from the gas burner is utilised for either electrical power generation or central heating and waste heat is minimal.
In the last stage of the process, the rotary motion of the Stirling engine drives a permanent magnet synchronous generator that produce up to 6.4kW of electrical output. This power output is managed by our own power electronics to provide clean electricity in whatever form, frequency and voltage the client may require. Unlike some other microCHP appliances, the Inspirit appliance offers an electrical output, suitable for connection to both single and 3 phase installations.
The appliance offers an overall efficiency of ~90%, divided between electrical efficiency (15%) and thermal efficiency (75%), and compares very favourably with conventional boilers, which typically run at lower efficiency in real world situations and deliver no electrical output at all.
at 20kw in 15%=3.2kw and 75% efficency is 15kw so i think that maybe its standard mode but as you say it may modulate and produce more or less elec/heat but as you say we are bordering on guesswork but this is my best one all imho etc etc etc etc
