    What are the pros and cons of these two models apart from the smaller footprint of the 20S, 715X405X248 and 780X400X338 (HXWXD) for the Mynute. The Mynute claims a modulation ratio of 10:1. The 20S is only 4:1, on start up it holds the output at 75% (15KW) for 15 minutes and then modulates as required, what is the advantage/purpose of this and finally can the Mynute be commissioned with a lower max output of say 15 KW but still modulate down to around 2 KW (20*1/10). Thanks.

    I was "reliably informed" that most smart gas boilers clamp the max output for 10 to 15 minutes, they look at the flow and return temps and do all sorts of calculations, rate of temperature rise, delta T etc and then release the clamp.

    Pros, not sure.
    Cons, they're Vokera
