We have tried isolating the radiators and only putting on the ufh to no avail, I believe they do share a tapping

Exactly my thoughts re the installers, I thought when I paid for installation it would include actually getting the thing working but apparently it was only the actual installation of the pipes and manifold then you’re on your own, there is a pump on the TS which is for the radiators upstairs and the UFH, works ok for radiators so I’m assuming the valves are fully open, yes a visit from @Nickfromwales would be great pity he’s so far away! And by the way it’s IRN bru?

That's not a ideal scenario.  Two sets of plumbers needed so will both find fault with the others work and blame the other when it doesn't work and you end up with the bill. 

Our plumber who did everything including the radiators seemed to know nothing about ufh so was no help at all, this system seems to be so different from the one we installed in our last house, hubby did it all himself and there was a comprehensive manual you could work through, this one has a couple of sheets of paper regarding manifold and that’s it!

Oh how I wish I hadn’t got carried away with energy saving, 20 k light between ufh and pellet stove and still no heat! If we’d put in an oil boiler and radiators we’d be laughing by now ?

@Christine Walker, I felt a bit like that myself trying to get my ASHP working, mine however was a self design and Ebay cheapy but it’s working now so don’t give up hope, lots of experts on here to help you.

Heating is on! Suddenly it started to flow on Friday night and all is now well with the world! But my god can that pellet stove eat those pellets!

we were told we would use 1and a half to two tons a year but I can’t see that happening, installer has said it will use a lot until the house is heated up and then settle down, I really hope so or I’d have been as well with oil. It’s a funny piece of kit, set the water temperature to70degrees and it burns away at the top setting until it gets to about 68 then gradually cuts down its rate of burning till it eventually goes very slowly, you then see the temperature drop gradually and when it’s down about 50 degrees it starts working it’s burn rate up again but this can take quite a while and I do wonder why it gets so low before ramping up again, I’m just not sure of it yet but I suppose time will tell, hope it’s not been an expensive mistake.

Glad it's working! My heating ate up the electric when it was on for the first time this year, but it did settle down after that. Hopefully it will be the same for your boiler. 

Mine would use around 1.5t a year. How much pellets you burn will depend on how big your water tank and how much hot water your build needs to heat it and your DHW needs. The price hasn't really changed much in 4 years.  Maybe an increase of  £60 a ton. 

So do you have a large store and get them blown in,  delivered in tonne bags or 10kg bags?? 

Mine will burn flat out till it reaches its set point then slowly decrease until its barely ticking over.  If the  ufh needs heat or you take a long shower and take heat from the tank and its temp drops then the  stove will quickly fire up until the  tank is back up to temp then dies of again. 

I have mine set that it doesn't turn on its self if heat is called for.  We just use the range of timed programs and have it come on at  6am.  It will then fire up  and heat the tank and any ufh zone calling for heat takes it.  The  floor will take heat and the stove replace it.  By 8am the  floors should be hot enough and my rad circuit will come in for  30mins to warm the kids bedrooms. The  stove then  turns off at 9 and  will maybe have burned 15kg of pellets.  If  no ufh zones needed heat then it won't burn as much. 

We use this setup from nov/ Dec to feb/March  depending how cold it is.  

Some days if the  house doesn't need heat it will use very little pellets. Haven't it programmed yet as it's still not cold enough so just give it a blast if and when it's needed. 

Good to hear, and probably just air-locked, hence me asking if they'd purged it. You can see a hose attached in one pic, is that now disconnected? 

Yes @Nickfromwaleshose is now gone!

So have you moved in now @Christine Walker? 

 

 

 

 

 

@newhomeno we’re in between! Getting all the flooring laid and the staircase should be this coming week, we drink coffee in the house but still have to eat in the caravan until the gas is connected to cooker, just so many little bits and pieces to do but hopefully in a week or so in time to get the Xmas tree up!
