HI I WANT TO COUPLE MY WOOD BURNING STOVE INTO MY EXISTING RADIATORS WHICH ARE AT PRESENT SUPPLIED BY A COMBI I DO NOT WANT THEM TO BE RUN TOGETHER SO I WANT TO FIT VALVES INTO THE CIRCUIT SO I CAN RUN THEM INDEPENDENLY

You would have to have a indirect cylinder and motorized valves ,clyinder stat . It could be done you would need a heating company to check it all out .

Downdraft will extinguish the pilot light flame too. there are flue fans that run off solar. You might want to look into one

You burn wood, and smoke goes up flueway.
You're not running chimney smoke through ductwork so you have a heat exchanger.
What kind of heat exchanger?
probably air since you're running through ductwork?
How much hot air or hot water is coming off heat exchanger?
How big of a space can be heated with that amount of heat?
Is the exchanger located in optimal location?

Considerations.
One room log cabin with fireplace will not stay very warm.
One room house with big wood burning stove in center, with hot flue pipe running across the room and exiting on far wall, will get warm-hot, but will cool off fast.
Why?
Because the BTU output of firewood is much less than electric, coal, oil, or gas.
Otherwise they would have made wood-burning steam locomotives. But the locomotive boiler cannot get hot enough with wood ... the boiler needs coal to produce enough BTUs to boil water fast enough to rotate the turbine and turn the wheels.

Maybe your wood stove output should be measured.
Don't forget a huge percentage of fire heat goes straight up flueway.

Your talking about running pipes outside to this building ?

I would say that the wood fire/stove must have a heck of a draw to affect the bathroom heater. Maybe a separate air supply from outside via a pipe,to the stove meshed off against vermin would decrease the problem. Plus it could stop cold air being sucked across the room from an outside door.
Downdraft through the heater could happen with either vertical or horizontal vent. More important is the direction of the prevailing wind [horizontal] ingress of water/snow etc [vertical]
We often use the separate air supply in the UK and if the pipe bore is large enough 4" plus it seems to work ok.

Hi - hope someone can help. I have a VOKERA EXCEL 80SP combi boiler and been without hot water/central heating for two days. The pilot light is on, the fan is on, but boiler not triggering once the hot water tap is turned on.
Hopefully someone come to look at it today but hoping for some advice. Anyone else had this problem?
Thank you.

remove radiator and flush through, knocking botton of radiator on to a heavy block of wood releases part blockage in radiator should this fal replace radiator remember to flush out rad/valves when you have radiator off best of luck

what do you mean from the radiator TEMPATUTE adjusting control ( thermosatic rad /valve) if so jurt replace valve

the boiler should modulate to controll the radiator temperature but the central heating will go off whilst you are drawing hot water
