    Just a update Melin homes has still done nothing about our heating system and has refused to re-house us so far, Over 4 months now and still no fix ,

    This is beyond a joke now,

    And off topic as far as we know Melin homes has done nothing about the anti-social behaviour we have had,

    So if we want a solution we have to do it our selves ,

    Almost 4½ months now and still our Nibe is noisy and our landlord and Greenhill construction never fixed the problem of low heat upstairs when it is cold out,

    We have spoken to the head of Melin homes and as far as they are concerned they will only monitor the nibe and that is it as far as we know and if we do not like it tuff luck,

    So if we are still here next winter we have to put up the problem of low heat upstairs as Melin DO NOT care that young children have to sleep in that environment,

    i have sent 2 letters to nibe, and an email, asking what sort of consumption of electric i should be using in my 2 bedroom house over the course of the year, they havnt bothered to reply, so i can only assume they dont wish to have anything written down that could compromise them.Every summer i get optimistic that my nibe fighter 2005 is running economically, i love my usage in the summer, and then as the weather starts turning colder and colder my usage soars, and i get into debt trying to keep up with the bills.Also the constant humming from my unit and my neighbours drives me to distraction i feel like im living next to a generator,whos bright idea was it to install these awfull units, and then try and persuade us that they were economical and quiet, im not convinced, and never will be.

    Hello all,

    So this morning the bill landed on the mat!

    From 20 Jan 11 to 11 Apr 11 (81 Days) the entire house (2 bed... just me) used 1341KWh (16.5KWh per day). Makes a change seeing as it was using that in a month!

    I have been billed £119.13 for the period. Which is nice seeing my electricity account in credit for once!! This works out at £1.47 a day and £44 a month. Seems pretty reasonable I feel. When I get half an hour I'll document the settings I'm using on the unit. As it is pretty warm at the minute the house is using approx 5KWh per day, so looking forward to the next bill! I've given up hope of compensation tho.

    Is it a two story terraced house of recent construction?

    What dates did the bill cover?

    As promised here are the settings I'm using on my Nibe 360P with RC10 Room Stat/Controller. These seem to work quite economically. These are for a 2 bed, 2 floor house (89m2 in total) using radiators and no underfloor heating. Obviously use them at your own peril as I am certainly no expert on these systems! Perhaps you can compare them to your own and may highlight some of issues?

    Well we have had good news with our heating system:j Greenhill Construction never did anything about it but Melin are installing solar pv with the feed in tariff for us :beer:we have had half the installation done and it will be finished next week we are having a 2.4k solar pv system installed and I have worked out we will save quite a bit in energy consumption:dance:,

    With solar pv in the summer months with the savings in energy consumption though out the day with the Nibe set to summer mode to heat only hot water it will cost us nothing to run_party_ and in the spring and autumn with the Nibe set to spring/autumn mode (immersion disabled) the Nibe will cost us less than 50p per day to run and come winter time it will also help a fair bit to,

    Also Melin are going to monitor the energy use of the Nibe 360P aswell I am very happy:cool2: now that this situation is now sorted out:T and I am happy that we are having solar pv as I know it is going to make a difference and the carbon footprint of our house will drop as well:dance:,

    I'm glad things are being sorted for you! Hopefully with the solar panels, the savings in the summer will go some way to offset some of the winter running costs.

    I've got a new problem. This time with the gas. I posted a thread the other day about it (see here: http://forums.moneysavingexpert.com/showthread.php?t=3189888). Guess what it is the same company who installed the Nibe System.

    I spoke to the company today as they wanted access to my property to put it right. Which will hopefully be on Friday. I asked the guy, who assured me it had been comissioned how exactly they did it, with the cap still on, the meter reading zero (no gas has gone through the meter) and a leak. Unsurprisingly, they couldn't provide me with an explanation!

    Hi there they are halfway through the installation the scaffolding went up today hopefully the solar pv will help with driving the cost of the bills down a bit:j , I just need the noise of the Nibe fixed now and hopefully Melin can sort the anti-social behaviour:mad: that some of their tenants are causing us out as we are constantly:( having problems the two neighbours with one trying to ram us off the road while reserving on to our driveway:eek::(,

    Don't get excited, presumably the FiT (Feed in Tariff) for the panels on the roof will be earning your landlord hundreds if not thousands of pounds per year. You will get £100 per year; or a bit more, if you try hard to balance your consumption to your production around noon on summer days.

    Your house is on the gas grid and should never have been fitted with a heat pump.

    Today the BBC has broadcast a programme about the use of air source heat pumps in an existing bungalow.

    I recommend the program, with the provisos below

    http://www.bbc.co.uk/iplayer/episode/b010vzmv/Dont_Get_Done_Get_Dom_Series_5_Eco_Heat_Pumps/

    Like any TV programme this one had to skate over the technology and totally failed to explain the need to insulate and draft proof before installing a heat pump.
    It is a trickle technology that cannot be allowed to "set back" more than a few degrees at night nor should it be allowed to "cycle" (ie turn on and off when the temperature falls or rises a degree or two.

    Heat pumps become less efficient as the heat gradient, that has to be overcome, rises. IE when is is very cold outside and the inside of a poorly insulated house needs to be at a higher temperature inside to maintain comfort levels; this is just the time that the pump becomes less efficient, especially as an air source heat pump has become an ice maker. (and the direct full price electric heating gets turned on to help melt the ice).

    I won't spoil the programme for you BUT watch out for the ruling that has forced all the heat pump companies to "modify" their promotional claims.

    The BBC employed a consultant to explain why the pump was not fit for purpose, but he did skate over the need to present a SAP (standard assessment procedure) to identify the heating requirement of the building and then seasonally model that against the equipment to be used.

    Turning to your "heat recovery" system fitted to a relatively new building:
    The building should be "built tight and ventilated right" - a block of (social and shared ownership) flats has been thrown up near me - I cannot comment on the general finish but I can say that the thermal blocks have been mortared together with really thick courses of traditional mortar, and there are some funny looking solar thermal panels facing East and West - so I think there is still a long way to go in this country in the "eco" construction industry.

    I still cannot understand how a heat pump can "make heat" by "swallowing its own tail":
    Your natural use of the home be will inputting energy while cooking, washing, freezing, and lighting. "Ventilating right" in a totally sealed home does require mechanical ventilation in most cases.
    (Google "Zbed" if you would like to live in a home that looks a bit like an oast house)
    Taking heat out of this warm air and the latent heat by condensing the moisture in this waste air, could make sense on the road to "zero carbon".
    BUT CAN SOMEONE EXPLAIN TO ME HOW SUCKING AIR AT (say) ZERO DEGREES THROUGH A HOUSE AND USING AN ICE MAKER TO GET A BIT OF HEAT OUT OF IT WORKS.
    (Talk me through the volumes of air and the maths of the heat extraction)

    [STRIKE]If gas is no longer available, I would get a night storage heater or three off Ebay and have a mate wire them in for the 3 months of next winter [/STRIKE]

    Sorry I cannot say that - it is now totally illegal - night storage heaters need a sensor in the garden so they (not you) can control themselves.
