    Anyone got experience of these?

    We've been looking for a quality pellet boiler at lower cost than the ETA's that we normally install.

    We have 'value' offerings from a well established UK company with a good reputation, however it isn't a 'name'

    The advantage of this - it comes with a brand, are they built by grant? Rebadged? Made where?

    Do they have any particular issues?

    I don't particularly like the type of burn back protection that tends to proliferate in this price range, though some other aspects of it look quite good for the price.

    Comments please :)

    It's made by grant
    It's a condensing pellet boiler
    Limited on size it you want bigger it's 2 boilers ect
    They say they work better going direct into heating not into a buffer

    I've footed a few they are good enough
    In same league as eta I don't think so

    I fitted a hapero it was a great bit of kit and I would put that above the eta

    I'm seriously intrigued by this, Alex.

    How does the condense pipework not clog up?

    There is a mains supply on a solenoid valve it washes itself out every so many hours
    Flushes out the condensate trap

    Thanks guys, so it fits in that gap below Eta which is fine, as going forward not all our clients want to spend that much capital.

    We're off to Devizes for a half a days training soon (having met us and seen our work, they claimed we don't need the two days like everyone else :) - We'll take a full day from them though, as to cover all the fault finding and service items properly will take a bit longer than an hour.

    @Gray0689 Interesting way to mount an expansion vessel, hope they're strong anchor bolts on that for when the bladder / valve fails, not just a bit of pasterboard :)

    Yep they're insistent that it doesn't NEED a buffer, though did acknowledge that it could be even more efficient with one - they claim 92% without on.

    And yes it does condense, apparently uses the same condenser as their oil boiler range.

    Iv seen the plastic pipe melted where it caught fire as it goes into the burner! Only a basic overheat stat on the hopper feed, it needed new o/h stat & plastic pipe etc... That was an early model, maybe improved now!

    That's the purpose of the plastic pipe - it's supposed to melt as part of the burn back protection :)

    Not as sophisticated as ETA's gate feed which cannot burn back.

    It's a common and accepted burn back protection method, not one I'm a bog fan of though.

    Would I fit one in my own house
    The answer is NO
    There not easy on pellets
    They tell to have problems with pellets sticking in feed tube
    For the price range there is better on market

    Lol they say that to everyone about training

    Yes 3 knock in anchor bolts 10mm rod and locking nuts the wall will fall first lol
