stove install with dry boiler

crzybkr73

a friend wants me to install a stove he got. it looks to be in good ondition but have not tested it (yet). here is my problem...it has a boiler fitted in it,which he intends touse in the future,but for now it will remain disconnected. what is the best solution for to protect the boiler fornow.some people have suggested filling it with sand, but this sounds messy and a problem down the line. also the flu has to go out through the centre of a corrugated tin roof. got any ideas on how best to do this. i am mainly concerned with sealing the tin against dampness after. i was thinking of cutting the roof hole about 50mm smaller han the flu and trying to bend the tin upwards to form a lip which can be covered in lead. is there a better solution that anyone knows.
finally when he does connect the boiler to a few rads, will it be neccessary to have a coppper cylinder to help regulate the water temp. imean if there are only rads the water circulating may get too hot

Contact a heating engineer, second hand boilers can be a dangerous thing. Esp. if installed by amateurs !

i am an amateur, but have some experience in this field(fitted a few stanley stoves, plumbed some rads, etc. i realise that there is a huge risk of explosion from a dry boiler. i will pressure test it for him later this week by capping off the outlet and fitting a pressure gauge assembly on the other side to see if it holds the pressure over time

Pressure test it by all means but always leave the boiler open (uncapped) to atmosphere if fitting without using the boiler.
My advice though would be not to use the stove if at a future date you want to use the boiler. Generally the boiler can become knackered as the heat generated distorts the metal boiler and can split. It's the water inside that preserves them. Filling with sand does not quarantee the boiler will function as with wraparound boilers it would be virtually impossible to fill it 100 percent.

If you want to quarantee a working boiler stove don't fit it without the rads connected:).

If it's a clip in boiler it would be best to remove it.

yes its a wrap around boiler unfortunately. this guy wans to heat his workshop for now, but cannot afford the rads or pipework costs at the moment. will i need to install a cylinder and vent tank as per standard install for the rads or will the rads be enough to stop the boiler overheating(my belief is they will not)

u will need a header tank etc in the future anyway so fit it now even with one rad, if u use it dry u will wreck it: also if u fill with sand how will it be removed, it may solidify with heat: get a copper cyliner and use it as a rad, not with a coil.

why not a piece of double skinned flue pipe for roof

This is a recipy for a disaster.

thanks, i realie this is a dodgy setup, i shall try to get him to reconsider

i have a kingstar stove which has a leak in the boiler i am planning on putting this into another house just to heat the room and not connect the boiler. i am planning on filling the boiler with sand and leaving the top pipe open plus possibly drilling some holes in the boiler along the top. this stove will never be connected to a heating system again so im not worried about the sand or holes but should i take any more precautions?

I have a leaking boiler in a morso stove. I plan not to use the stove boiler to heat water but keep the boiler and disconnect and remove water. It has been suggested to me by a plumber to install four custom made firebrick to front boiler and also fill boiler with fine sand. The bricks would have to be made to measure.

I see on some posts where it is suggested to drill holes in the boiler for a heated air supply and not leave boiler pipe hole uncapped - so I presume that no sand is used in this approach. Am not sure about these air holes.

I have not started this project.

If the Boiler is leaking, then its very likely that fumes are getting into the boiler section. Therefore you cannot use the boiler as a hot air supply.
I would also presume the leak is going to be positioned in the area where the most poisonous gasses are generated.....

I would suggest a leaking boiler stove should never be used again.

I found a website where I can buy 4 made to measure firebricks to build in front of boiler in my Morso Dove stove - one each side and two at back - because of slope. see fire-bricks.com. They can be built in such a way as to not restrict shaking the ash riddle. Disconnecting the water pipes from stove and filling the boiler with sand is a separate step. The above is the plan - I have not started the work yet.

Has anyone ever seen or used firebrick built in front of a dry boiler?
