on a standard bike, there are pedals to measure the power but it's not given. several hundred euros.

The slopes are probably more problematic, but the argument of the weight surprises me: vertically, the power is limited by the weight of the cyclist, since when the effort is greater than the latter, it is no longer useful for propulsion. ... In the recumbent bike, the effort of the legs can take ...

I really warn you about changing your pellet boiler by a more powerful one. chances are this is a bad idea. in a pellet boiler, it is not like an oil or gas boiler, it is not "who can do the most can do the least" with an oil or gas boiler ...

the problem is the volume available. the price is without direct correlation except in the short term. we do not go from an available volume equal to what we consumed the day before to ZERO the next day. it is the misleading effect of the R / P ratio (current reserves / consumption) which can be wrongly interpreted as X ...

as indicated by Remundo, the overlays in 2017 broke a record. never have we discovered so little oil on 1 a year. some will say that it is because we do not seek much since the price is low.

seen the black mouth full of bistre of this piece, your combustion must be disastrous.
you have to find out why quickly, otherwise you will damage your boiler.

never seen on my boiler.
will you have a picture of where it is?

second math course: equation of a straight line.
coef director (slope) = m = (Yb-Ya) / (Xb-Xa)
intercepted = Ya-mXa
in your case: slope = -1.48
origin = 64.1
with that, you can calculate the theoretical start time for all ext temp.
for example: if temp ext = 5 °
start time = -1.48 * 5 + 64.1 = 56.7

without a weather station, this kind of follow-up quickly becomes tedious and compelling.
Long live the progress and the graphs that fill themselves.

the correction by the room sensor only shifts the heating slope parallel to the red line of my graph.
for thermostats, they must be open.
