Rail001, are these guaranteed for 10 years?

Alliander feed-in tariffs +€265
Statutory funding +€860

Also, there is no allowance in that example for the price of gas or electric to go up/down over the 10 years, which it is guaranteed to do.

Neither does the example allow for the stack degrading (which ALL stacks do over time) which will reduce efficiency from 60% down to probably below 35% over the 10 years, so power output will be 43% lower, falling to that over the 10 years, so the returns will diminish each year to a final 43% per annum below where it started.

The example is what I refer to as 'massaging the figures' and any technology person or boiler salesman will spot it straight away.

Where do you get your numbers from? Price here in the BG pricing file is €29,750, not the €28,000 you are quoting.

Stack degradation:

Efficiency Degradation over past few 1000hrs about 0.5%/1000hrs

8760 hours in a year

Degradation per year 8.76 x 0.5% = 4.38% (linear degradation applies)

Year - Percent Efficiency
1 - 60
2 - 57.372
3 - 54.744
4 - 52.116

Your savings will never happen because the degradation reduces the returns year after year. Payback will never happen in 10 years. Chances are that a new one will be needed before the 10th year as the user will be 50% down on power output by then and will be spending cash on electric from the grid.
