central heating from a log burner

[AstonHill]

Surely you connect both connections to the rad to both connections to the heater, teeing off from one of them to go to the header tank to act as the fill/expansion pipe?

Do you mean like this?

If its a back n baffle boiler and not wrap around it will be less than 2kwh output

I poured water in it other day and it came stright out so cant see much of a tank there really

What do you think the minimum a tank would hold?

So is my latest diagram right then?

 

[lostinthelight]

Are there firebricks each side with the boiler forming the rear wall,then sloping upwards and forwards to form like a roof over the firebox

No.

Yes fire bricks at the walls. yes boiler forms rear wall and yes slopes upwards

 

[AstonHill]

No.

Then what did you mean? I though you said the rad should connect to bough sides of the boiler

 

[lostinthelight]

Yes fire bricks at the walls. yes boiler forms rear wall and yes slopes upwards

So TBH that wouldnt be worth the effort and cost connecting to rads, just DHW and heat sink rad

What do you think its out put is

What do you think its out put is

As I said earlier, less than 2kwh
Edit made a mistake on the conversion, 3.5 kw

 

[AstonHill]

I can tell you for now! that puts out more then 2Kwh

Thanks! But I still feel it could and sometime dose more then that. What makes you say or think 3.5KWh though as you seam to know a bit about the log burner in question As I would say more 5Kwh

So lets just say we keep it nice and simple for now and hot water tank for washing only and no rads. Apart from the "safety header radiator" needing air venting and an inlet and out let on the header tank. Dose my latest diagram look ok?

Thanks

Simply unsafe.

If the stove can create 5kW of heat then to be safe there has to be a way to dissipate that 5kW of heat into air and/or water.

How can you tell that? What were you using to measure the Kwh with?
