Scotte V7 graphs

[manniste]

Hi,

I took a look at my Scotte V7 graph and it looked really jumpy.

This is me: http://stokercloud.dk/dev/showgraph.php?mac=kikumiku

Is that ok?

I clean everything every weekend. Pellets have been the same for many years.
Circulation pumps are "smart" Grundfos pumps, every room has its own thermostat.
Chimney draught is good and has a regulator.

And I have a friend with same burner and his graph is really smooth.

Our houses are different size, mine is about 300m2 and his 120m2, but still shouldn't this burner be able to handle the power management efficiently.


Thanks for your help.

Thanks for your help.

Start by updating to version 7.0640
Set up your pump in constant pressure / speed.
Search for a heat consumer that open and close frequently.

Alright, thanks for the quick response.

Did the update.
Three rooms had a timer adjustable thermostats, changed them to normal ones.
Changed the circulation pump to more consistent flow.

Hope for best

Nope, still jumping a lot.

The circulation pump is at stable speed (faster than it was on automatic mode though).
All the rooms doors were kept closed to let the thermostats work properly.

Any more ideas what should I consider?

When I look at the graph that suddenly goes down,
then it must be a large heat consumer is opened for.
Maybe it's your input temperature floor heating which is too high.
Try if it will be warm enough at 30 or 35 degrees.

[manniste]

I only have radiators, no floor heating.
Basically heating only two floors. The feel of the warmth is constant, I don't feel that the rooms are getting warmer or colder.
Basement, attic and the garage are turned to 16C.

Look for the valves to your radiators can adjust how much they can turn on the water
(I dont mean the temperature but the hole for the hot water supply)

If supply to each heater is adjusted to it just gets hot enough to keep the room temperature,
there will not be as many variations in temperature in the boiler.

Perhaps this task is a job for an installer.
