Was size of boiler is that FFG?

Will keep the bags on the pallet in that case - my plan was to have two at any time so that we don't have to panic buy.
21kw. I wanted to go 26kw but was told if its to big it will kick in and then go cold which is less efficient so I went with it and there was a potential to upgrade to 26kw for about £250.

So installation kicks off tomorrow - they are working over weekend to make sure its done in time for the RHI reductions, which is really good of them.

Most interested in how they intend to get the thick underground pipe into the house. Its a solid concrete foundation due to the water table around here (near to sea and low land) so I am interested to see how the are going to do it and protect the house from water ingress!

Perversely the weather is getting better, but a high power unvented shower is going to be a treat.

Well a week in and enjoying a rather too warm house at times.

I have a few niggles about how pipes come into house and are exposed outside (although covered) but overall it's good to have an even temp in the house.

What I would say though is there are some un-expected elements to this. The manifold system in the utility room is an impressive feature but something I wish had heads up about in advance.

Pellet use seems a little high just now, but I have yet to start tweaking the timings and temps much. It has weather comps, which I gather take some time to settle in and get used to.

It seems to come on very quickly after water use however and is set to keep the temp of the hot water to 55c constantly. I gather that its more efficient to have the boiler coming on more often (it does modulate) but the old school in me wants to set it to only heat water during peak periods!

Well for anyone interested - we have the first breakdown. They are heading out this morning to check but it looks like the auger motor has failed.

Funnily enough they had trouble starting it on install and it was "clanking" slightly last few days (I did call them).

Hoping this is a teething problem.

My guess it will be the plate at the bottom of the burner bowl which spins around the clear the ash when the pellets are burnt. This needs to be in properly (over the 2 guides with the pin nearest the door (you'll need to lean in to see it) through the hole and the plate flat on the base of the bowl) otherwise it will make a clanking noise, like metal on metal.
This plate also gets caked up in carbon so will need cleaning say once a month at least. Ours has suffered recently as it seems to clog up a lot quicker which we were told could be damp pellets and the moisture is causing the ash to stick and build up as carbon therefore inhibiting the movement of the plate - but the pellets are inside by the boiler in a dry warm environment so don't believe this.
Assume you've been told you need to clean it regularly and left the tools to do it. I always empty the ash bin at the same time now.
Have Windhager commissioned it yet? Does the display screen go red and return an error message?
Good luck.
After the first breakdown about a month ago, which was the heating element replaced under warranty, we also got another as a spare.

Thanks for that!

The pellet feed wasn't working at all and it was displaying an error in terms of empty burner bowl. Turns out that's the error for the heating limit being exceeded, because no pellets were getting into the burner. I emptied the hopper right out and sure enough the auger wasn't turning at all.

They messaged to say its fixed a wee while ago - but no explanation yet.

They commissioned it themselves, but I email windhager about a few things and changed quite a bit. I am tempted to ask if they will come up and review the whole boiler set up make sure its running right.

Examples being that the boiler optimisation wasn't switched on - despite me having the MES+ weather comp.

I think you need eyes open on this for complexity levels before fitting TBH.
