i have a solid fuel woodwarm boiler which im removing and want to install a solid fuel rayburn. the problem is that there are 3 pipes coming from the woodwarm, from what i can make out 1 outlet and 2 return feeds and the 1 return has a pump on it which send heat around the raidiators. the problem i have is that the rayburn has only the 2 pipes inland outlet, can the two returns be plumbed into one or do i have to make major changes to the system.
please advise
 
the flows come off the top connection the returns off the bottom can't see no reason wy you cant t the two returns together close to the boiler alot of gas back boilers where done like that
 
I would recommend you get a professional to look at it.

A common means of driving heating from a conventional heat store type Rayburn is to use a thermostat on the hot water side which when a set temperature is reached to drive a pump and send the primary water round the radiators.
 
They have a pipe stat to overide the heating timeclock so if the cylinder starts boiling it turn the pump on to heat bleed the system went to one where the customer kept turning off the fused spur off to the randall time clock and he had even put copper overflow on the fe tank because the plasic one had melted very scary
 
it seems to me that on your woodwarm you have a injector tee fitted this allows gravity heating to work to your hw cylinder and when the temperture is reached the pump kicks in and sends the heat to the radiators therefore you would have the 3 pipes look-up injector tee for more info on google or something.


if the rayburn you have only as two pipes it is most likely to heat your hot water only with a flow and return gravity to a seperate heating coil in your hw cylinder.

the way in which i pipe them is two pipe flow and return gravity to the hw cylinder and then put a wee heat leak radiator after to take heat away once the cylinder is heated, and them connected your cold feed and vent as normal
