I think you are referring to the heat leak radiator being ommited on the schematic.
From the sfa.....
The heat leak radiator is not a safety device but serves to reduce the risk of water boiling and discharging into the header tanks and out the overflow. I am not aware of any legislation which covers this issue.


MI's always superceeds the regs in any case.

No it is the solid fuel boiler in the link which is on a pressurised system
 
The Stanley Brandon in the link is oil fired. So ok for a sealed system.
 
you have to think of others looking at this thread and thinking its ok to put a solid fuel boiler on a pressurised system, as this thread is about linking solid fuel to oil

There's nothing in the link to suggest connecting a solid fuel boiler to a sealed/pressurised system. What link are you looking at?
But since you mention it, it is OK to put solid fuel on a sealed system in the uk. Broseley fires for example have scws fully approved for use in the uk for solid fuel stoves engineered appropriately.

let yaz know how i get on, will be fitting the stove end of next week!
 
near all finished just need to connect pipes to boiler and fill the system! 1 more question the customer is now putting a harth around the stove and he was asked me to move the pump up above the ceiling into the roofspace, was thinking of putting it on the return to the stove,the only thing is that i have the feed and expansion on the flow out off the stove would this cause any problems?
 
What way do you have it piped? Have you used 4 pipes, ( 2 for gravity, normally 28mm & 2 for pumped circuit).
The gravity pipes should have a vent on flow & a feed on return. No valves or pump.

no i went the fully pumped route customer didnt like the idea of his new wooden floors being ripped up, he was happy enough to go ahead with it fully pumped! i ust have 2 pipes going to stove and i have the cold feed and the vent coming off the pipes when the enter the roofspace! The pump isnt blocking the vent as it is on the return to the boiler, i have a 22mm vent and cold feed coming off the flow pipework 100mm apart!
 
Not a way I would think of doing it. Assume you took the pipes to cylinder & then rads. That means the pump is on the gravity return, near to boiler?
 
Fit a gravity heat leak rad of the correct size, if the power goes off the heat has somewere to go, it is not a requirement to have gravity to the cylnder as long as you can get rid of the heat in a rad
 
I would advise a fire to have a gravity circuit bare minimum with flow having a vent, return a feed pipe. Some systems have been done with a pumped circuit teed to gravity circuit. At least this is not dangerous.

Gravity return? as i said there is no gravity circuit, the two pipes just link into the existing central heating pipework where te flow and return enter the property! yea the pump is on the return to the stove near the stove and feed and expansion is on the flow from the stove???
 
Yes agreed cold feed on return and vent on flow, this needs changing
 
I'll not lose any sleep over you that's for sure lol
You want to be a cowboy that's upto you
 
Water being heated from a fire must rise, as on a gravity circuit, or be pumped constantly, BUT, you can't rely on a pump & you really shouldn't have valves on gravity pipes in case they fail or some idiot closes one accidentally. Hence gravity is the only way. If fire is going full belt & the pump stops for any reason, the boiler will come under a lot pressure, & I wouldn't want to be in the house.
The stove manufacturer will not accept your install, I am sure.

cheers, whats wrong them both on the flow tho?

Why are you doing work that you obviously have no experience in. The key is safety first and it appears from your posts that it is not safe.
You'd have been better teaming up with somebody with good experience of safe installs, would have set you up a treat. Everybody's gotta learn somehow.
 
Best said:
More important is, where is this stove installed? .... Just in case it is in a house next door to me! Lol! :grin:

That's what I was thinking too lol
Glad it's not near me
Mr flux I guess you plumb in the south as any decent plumber would not do that in the north

Connect a solid fuel boiler up with a vent and no cold feed/expansion the water will simply boil off. I know that because I've done it.
After that its stress relief time for the welds.
Did you read what peteheat wrote on the bs6700 thread? That guy knows his stuff.

Where is it going to boil off to if you seal it?
There are ways to do this properly as i'm sure you are aware but none are yet approved for use in the uk.
Do what ever you feel right for you but don't encourage others who know no better to indulge in your experiments.

If a stove with thermostat control you need an heat leak rad of at least 10% what size for a stove with no control at all!!!!!!!!!!!!!!!!!!!!!!!!!!

Through the vent.

Ok if water is boiled off out of vent how does this get replaced? You need to have a read of the requirements for solid fuel boilers in the UK. This is a UK based forum and we have to conform to the requirements, if you are outside the uk that is up to you, carry on, but don't encurage other to follow

Someone said its dangerous. Its not. I'm well aware of the regs.

I apologise for misreading your post. I saw only "no cold feed/expansion" and thought you meant sealed.

You are still encouraging practices of which not many people are aware of the consequences if not done correctly.
Why?
 
And who MI's do you comly with? all manufacturers base their instuctions on the the regs unless of coures you fit some dodgy chinese carp

What solid fuel stove manufactorer would allow a vent only no cold feed???????
 
I would encourage Mr Flux to adhere to the MI's. But they seem to be scant on information regarding the piping layout.
I'd also recommend a clear and unobstructed path to the boiler.

That is because they expect it to be fitted by someone with some idea of the regs
