woodpecker wood pellet boiler heating the rads and water

[rogerdodgerorkney]

Hi all,

i am having an issue i think!!

i am burning about 1 tonne of pellets a month. (£300) 4 bed house with 11 rads

boiler stat set to 70. water temp reaching 55 max

got a cold house!!
the rads aren't really warm, tried balancing them. getting better now, after opening all the trv's and closing all the lsv's then opening 1/4 turn.

water temp now 57-58 max.

am i missing something?

If I left my oil boiler on all the time I could probably burn £300 quids worth a month in winter.
Maybe your boiler is undersized or bad quality pellets!

Hi, sounds like could be the buffer set to low (if one fitted), also on the read out on the bottom right it's says 70? What temp is on the large read out?

 

[rogerdodgerorkney]

done the whole balance radiators thing.
working better, boiler is set to 60 now, and getting 56-57 on main temp.
it is modulating now down to 2 so i think its probably working as well as it can.
how can i check my buffer?

You can check the buffer by pressing the bottom left button (set) then scrolling to the buffer thermostat and pressing set again. This will show you the target buffer temp . You can do the same with boiler temp and this needs to be 10-15 deg c hotter than buffer.
How long has the boiler been in?
When you say hot water do you mean the central heating or domestic hot water from tap?

Sorry forgot to ask, what temp is the flue gas when it's on power level 5? If above 175 deg c then will need a service as the flue gasses are passing through the heat exchanger without being absorbed into the water

Where do I read the flue gas temp from? On the monitor?

Not got buffer temp in the menu.
