Would a 6kw (nominal) stove power 4 radiators and DHW?

I have the Stanley Oisin 6 kw and was wondering if I should buy the boiler kit? I have two double pannelled radiators in my living room and would mostly be interested in having these heated. At most I would want it to cover 4 radiators (there are 7 in the house) at most. Could I simply turn off the ones I'm not using like in a gas or oil CH system? Also, is there any way I could install a boiler option to then off the option to heat the water and/or the radiators, in other words, to just have the stove functioning as it is now?

The 6kw probably wouldnt keep the rads very warm, not all of the 6kw will be going to the boiler side of things.

Take my stove which has abuilt in boiler:

if run on wood total output is 11.Kw which equates to 4.6 to space heating and 6.4 to central heating
if run on anthracite then total output is 16.4Kw equating to 7.1 space heating and 9.3 to central heating

So if your stove without boiler in is 6Kw you are really only going to be getting 2.5 / 3.5Kw to heat the water, the rest will be radiated into the room as space heat.

In all honesty HR you would be better off saving your money and getting a larger stove with boiler ready fitted.

When getting one with a boiler in as well there will be changes needed to your central heating, a metal header tank would be required, a heat sink radiator will be needed - essential for if you get a power cut and the pump stops otherwise you run a significantly higher risk of the boiler getting too hot and cracking and or exploding.

As far as fitting the boiler if you did and turning if off if you didnt want the water heating...you cant ! you constantly need water in the boiler if fitted otherwise it will warp - split crack etc and render it useless.

Combining a solid fuel stove/fire with a Central heating system is a complicated, and hence costly, procedure.

Ok nice advice - what do you imagine is more expensive, running an immersion heater - for around 1 hr - a day for enough for a bath or using an electric shower for maybe 10 minutes? In future I would like like just to have a stove and no CH at all - I don't need it.

An immersion heater would use 3kWh a day - say 36p @12p/kWh

Electric showers vary in power, but take a midddle of the range 9kW shower - for a 10 min shower that would use 1.5kWh - say 18p.

Ok, now here is an interesting question - does using a boiler with the stove require significantly raised amounts of fuel? I have spoken to people who had open fires with back boilers who said that the back boiler for CH was more like an added bonus and did not require large amounts of additional fuel. With a stove connected to a back boiler for water and/or CH, would I be using vast amounts more fuel to keep the system going, as well as throw heat out of the stove?
