woodburning boiler stove

[supersyd]

Hi
I am just about to plumb in a woodburning boiler stove.
It has 2 22mm pipes coming out the back which I wll plumb into the radiators and 2 28mm pipes which I will plumb into the hot water tank. Do I need to put in a heat sink into the hot water system and do I need to put in a seperate pump into the radiator system.
Thanks very much
Tim

Can you design the system so it works on gravity only so that the heat can be removed from the boiler if an electrical failier happens.

Also do you know that an incorrectly fitted stove is just has dangerous as a gas boiler .......... carbon monoxide

Also what happen if Dihydrogen Monoxide leaks?

Thanks for the replies.
I will make the 28 mm pipes to the water tank gavity feed but do I need a heat sink as well?
I have fiited quite a few woodburning stoves before and am awre of the risks but I have never fitted one with a boiler before.
Thanks very much for your imput
Tim

28mm to hot water gravity
22mm to rads pumped
No heat leak required

Generally yes but read, and understand, the mi's.
Also consider a metal header tank and a copper ball for easily thought out reasons.

Once again thanks very much I do have a copper header tank it is built in on tope of the hot water tank I will make sure it is a copper ball as well and go for it
Fingers crossed!

Check the stove MI's to see if they recommend a minimum cylinder size too,it sounds like a Fortic cylinder you have there so they can be on the small side,in which case you might need a heat leak. If in doubt I would speak to the manufacturer and go with their recommendations.

Yes it is quite a small tank and very small header so I may put a radiator in the ho****er system just to be sure.

Sorry did not know it was a combination cylinder you will need a heat leak rad

 

[tamz]

Better to put in a copper overflow too.

does the cylimder look like this

This is a thermal store

No my tank is very old but it is a simular design it has the header tank built in as there is no access to the loft space.

What is the output of the stove in Kw to water syd?

Hi
Hot sure what the kw of this stove is as I bought it second hand.
I think I will give it a go and just plumb it in.
