Preservation of the boiler would be my main reason, everytime your open system expands and contracts, it draws oxygen into the water which then causes corrosion in the boiler and pipes and reduces the life of the plant. A sealed system if done correctly and you don't have any leaks would drastically reduce this . I would certainly suggest sealing the primary side and transfer heat through a PEX

Fair enough, makes sense, thanks for that. All our secondary sides are sealed, just boilers that are open.

Agreed
Farm 2000 is open vented to an expansion tank above the accumulator tank, cant really say that it draws any new water into the system, just expands into the header and contracts down when cooling.
As mentioned earlier I have a 195 Glenfarrow - installed in September 2013. It has generated around 300mwh in that time primarily on Oilseed rape straw, heating a 8 bed old farm house, 2 x 3 bed cottages and a workshop.
My understanding of the output rating is a calculation done taking into account the type of fuel and the size of the chamber.
We looked a various different systems, my aim was to be in control of the fuel if possible. As we have a cattle enterprise we have a baler, use a forklift 365 days a year and grow OSR the batch boiler suited us.
We chose Glenfarrow because we believed they could deliver the project and I was not disappointed. Excellent installation, all the RHI application work (tight timescale due to emissions specs introduced around installation time) and the service is second to none considering they are based 250 miles away.
We have had to learn how best to run it but I do not think I would change much if I was to do it again.
From what I know of Glenfarrow their business is industrial heating, irrigation and biomass. In my experience is they know about plant design and installation (then again I do not).

@T C
V similar here. Preferred F2000 as from memory more heat tubes and in general better built (it weighed more!)
You are spot on with fuel - takes some fine tuning, what are you getting out of a bale?
I think all these boilers do work if installed right, I just think sometimes tight farmers or muppet domestic plumbers have a go and get it wrong

Sealed system here - No cold water header tanks to worry about here !
As mentioned above Expansion vessel sized per system schematics.
Pro s and con s with it but an approved , qualified, clip board weilding money charging expert will tell you ???

It's the clip boards that cost the money I reckon!

I just make do with the bonnet!
we chose glen farrow because it was a turn key deal amongst other things.
they supplied and fitted boiler, and did the RHi with no issues. we were approved very quickly.
Neighbours who used a different supplier are still having issues.
For that part im happy.
HOWEVER, glen farrow were not bothered about accumulator tanks and did not really advise very well imo. As we had a 12000 litre stainless tank, it was OUR idea to install it. Im very, very glad we did.
We heat an oldish farm house and a workshop.
Ive not done it well enough to work out power outputs etc so cannot comment on that part.

sorry i'm not the best with a camera
they do have over 300 systems out like this from what i gather

Yes it's been in a while now, we have no accumulator tanks and part of the system is closed as the houses are higher than the boiler header tank. It works away for us as it's very simple just like me. I have found GLENFARROW a good firm to deal with.

just signed back into the farming forum after not being on for months!
boiler update;
4 months later we have installed a 2nd glen farrow boiler, to be fair to glen farrow they have resolved any issues we were having with the 1st boiler, quickly and efficiently, hence we've installed a 2nd system the same!

WHAT WHERE THE ISSUES YOU HAD?

the issue was not with the boiler itself, it was the fans in the back of the log kiln not being the correct spec. Turns out the supplier GF used had changed the spec of that particular part (FANs) without informing glen farrow, so glen farrow then replaced the fans with ones that were more than upto the job, using more than double the heat to dry the logs. to be fair glen farrow sorted it and got the system working as promised, and as i commented previously we then installed a 2nd unit, and then a neighbour installed a unit upon our recommendation.

Very good, Paul from GF is coming to see me end of the week regarding a log drying kiln and 210kw system.
