    ASHP for heating setup

    Thanks chaps, @ragg987 @ProDave @JSHarris I went for the simple fixed temp solution first off. A little tweak on some of the UFH flow rates also seems to have evened things out. So far Energy consumption has reduced. I'll play along for a bit. I might return to weather compensation once I get to grips with the Samsung unit and their explanation of the Water Law.

    ASHP for heating setup

    I'm currently set on a compensation curve - but the unit is defrosting more frequently than I would like, and then working hard to reach temp when the thermostat timers knock the temp down overnight, possibly too much. So it may have the wrong compensation curve, or be slightly undersized ASHP for the temperature, I did all the calcs as did others and the 9Kw unit should be enough. I think I'll try a KISS methodology and set a flow temp and limit the temperature differentials on timers on the thermostats and see how it goes.
  3. Hi All, I'm sure this has been done before and in depth, but as a kind of straw poll what do people find the most efficient configuration of providing heat to the home. As we have just having our first coldish spell using the ASHP. I'm thinking about: Temperature Compensation vs A Set water discharge Temp. Thermostat timers vs No timers. Constant Thermostat temperature, or a couple of degree differentials. Anything else?

    OS Map Requirement For Work on TPO'd Tree

    Have to agree, last time I did this, especially given the history, I dotted the I's and crossed the T's. From memory there was an LAPD online check list for bits and pieces to supply. This included a detailed sketched plan of the site, location of the trees in relation to other trees, buildings and roads etc To be fair to the most recent tree officer she said keep the wording and plans etc and just re-submit the next time you apply for works. Time will tell if it's that simple. where tpo's are concerned Good Luck is what you really need

    Daikin Altherma ASHP Heat Output Issue

    @joe90- Don't want to jump this thread, but I'm having a similar issue with regards to Air in the system, some loops just will not heat and I'm struggling to release the air: "I concentrated on heating only at first and found a lot of air in the system so powered the pump directly and left it on full chat for an hour which released a lot of air." I'm not exactly clear what you mean by this, could you explain, it seems to have worked for you.

    Floor tiling Prep.

    Thanks Nod, I hoped to have minimised UFH as an 'issue' by running the "concrete cure" UFH function on to help dry out the floor before even thinking about getting a tile down. That and the decent weather.

    Floor tiling Prep.

    Why is this ^ ? Adds substantially to the job price - I was considering not using the decoupling matt - seems to be mixed opinions as to whether it's essential.

    Floor tiling Prep.

    I'm prepping a large floor area for tiling. I expect to be using a Mapei Adhesive so for priming prep of the floor do I use the Mapei Primer G or go for a more generic SBR product, it looks like I may get a better dilution/coverage rate for the SBR so may be a bit cheaper. Any pre -tiling prep advice Cheers

    Green roof

    in our submission I have a small green roof. (eco credentials) It will be the last thing we do and it will the cheapest and most low maintenance I can find...as money runs out a Green roof does not get us in through the door.

    PV up and running

    The electricity co. won't/don't accept the "As Design" EPC. Got to be at least the "interim" version - but to get the "elevated" FiT it needs to be before certification of the PV, so the PV is not included in the EPC figure as @le-cerveau has pointed out. - it's all "Ar$e about Face"

    PV up and running

    @le-cerveau I want to do exactly the same thing to get the "better" FiT rate and not miss out on the summer of generation. Did you have problem getting the interim EPC - my current Assessor doesn't want to do one, but If as ask a new assessor they say they have to do the whole thing from scratch again costing hundreds, what all I want them to do is lodge the interim. which should only cost a few quid.

    Digging in the Verge

    unfortunately I've not been able to confirm any existing wayleaves, the hatch has 2 existing houses connecting to it, however the cover and chamber lie mostly within a boundary, if it was in the drive way it wouldn't have been a problem. The 2 houses in question, were built by an individual 1980's who then sold this one. I secured the plot the other side of the existing drive. Yep, would probably cop for most if not the lot. worth considering though ?

    Digging in the Verge

    It wasn't a problem, but now is, the lateral inspection hatch rests partially within the neighbours boundary and they have now at this late stage decided to refuse permission to cross the boundary to lift it. I don't want to go there!

    Digging in the Verge

    Yep, I tried these: www.swqr.org.uk "street works qualification register" - apparently they don't have a register they just dish out the cards....they said try the council. I have gone back to Highways at the Council......this could be a while.

    Digging in the Verge

    Due to some unforeseen and recent neighbour issues we may be forced to redirect our waste to further along an existing lateral drain. This would mean joining to the drain in a large verge inserting a new Inspection Chamber and connecting. I have to submit an S50 + extortionate fee to the council to "dig in the highway", it stipulates that I have to use accredited contractors for this work. The council so far are unwilling to give me a list of accredited contractors, so I'm wondering what is an accredited contractor, how do I get hold of one. My contractors are happy to the boundary, as a building contractor he says he is not "accredited", but I fear I'm going to get stung by a large contracts firm to dig quite literally the 2m from my boundary to the proposed connection point in the verge.
