    Hi all.
    I've been reading this forum for the past year in the hopes of gaining tips on trying to make the home we bought in March as enviromentally friendly as possible within the scope and budget of neccesary jobs.At the moment it runs from a solid fuel coal fed back boiler with a few storage heaters in hallways and the extension.
    The house is a rural 3 bed in a row of eight down a private road,built in the early thirties and has a solid 9" brick construction with a dormer style bedroom window at front and back.
    We plan(planned) to add oil condensing combi boiler( no gas in village) to heat and provide hot water since the immersion heater is old ,badly positioned and there is very limited space in the loft which meant the water tanks were housed in a bedroom and were keeping us all awake every flush of the loo.
    Since requiring new lighting we also planned to install low energy downlighters and where apllicable low energy pendant fittings(since then read on here there may be problems with building regs). Ahhhh.
    First thing we did was look into cavity insulation when we moved in which is where we discovered the solid walls.Next we planned loft insulation where we were told we would have to remove all the fibreglass that was stuffed into the eaves and replace the lot,which we will do.
    Before we chose oil heating I spent hours and days reading up about the pros and cons of every type of heating from ASHP to biomass but every alternative has a double edged sword.Smoke pollution from wood burning,difficulty gaining pellets,cost of installation,ect.Yesterday I looked forward to my plumber starting finally on the oil system.He had asked buiding control to pop out and give him advice about siting the oil tank as we have only a narrow passageway at the side of the house and because of a long extension wih a further conservatory it wasnt possible to place the tank in the backgarden.It would have been 50mtrs from the tanker and ruin our narrow garden.
    In line with my oftec registered plumbers advice we had replaced our fence panels with concrete panels and built a level sturdy base.Because my conservatory window was only 1.2mtrs from the tank we were told it's a no go.Despite my plumber explaining that we intended to surround the tank on three sides with fire barriers going slightly past the tank.Madness!! As i sit looking out at next doors tank fitted last year and directly next to the barrier fence and his shed it just seems totaaly unfair and ridiculous.Oftec had stated that although they cuoldn't pass it buiding control had more power to make exceptions and had phoned building control and told them that they regarded it as safe.
    We have a 7k budget to update the heating and water and make the house more HIPS friendly.No room in the property for vast storage tanks(it was hard enough to find the space for the boiler),the kitchen is very narrow.
    Is updated storage heating my only avenue?
    Very depressed and at my wits end.

    Hi Susie,

    The design of our house is such that we would also have to replace our existing oil tank ( which is currently against the back wall of the house) far behind the house out of reach of the oil tanker, which would require pipework and valves to allow the tank to be filled. The replacement of the tank and piepwork alone was going to costs us £2300 on top of the £3500 for replacement of the oil boiler controls etc. Which is why we have decided to add a bit more and go for a log boiler instead, but this need a big thermal store. I share your frustration about building controls in the UK. I always thought the Netherlands was very big brother.

    The quilt is a great idea and greener than green

    There was no reason to chuck out old fibreglass insulation -- that was ungreen. Putting in more was a good idea

    Cant see why tanks cant go in loft -- try coffin tanks?

    A couple of air source heat pumps or even three would do you house most of the year and cost less than 2k they only use 1/4 of the electricity too, for the same heating effect. Try them? gshp may be better but air source will do.

    We'd better have a discussion about the sustinable population level of eider ducks and the ethical position of nicking their down.

    Where did the OP say they were using Eiderdown? They might be using duvets filled with Thinsulate (TM) polyester insulation ;) Now, how green is that?!

    An ASHP would be a good choice as electricity is the most flexible fuel long term. Neither gas nor oil represent a long term view and everyone knows my opinion of wood burners - neither sustainable nor clean in present form.

    Sorry Paul, I just assumed that nobody posting on the Green Building Forum would entertain the thought of using a plastic duvet. The choice is between eider or goose. Or do I hear someone suggesting sleeping in multifoil?

    The cost of an eiderdown duvet is about ten times that of goose down. Yes eider down is best but at the cost of robbing the eider nests. Plenty of Hungarian goose down available.

    Now surely we have to be thinking of using an under-used resource. What about urban pigeon down, or magpie feathers? Seems to work OK for them.

    The Multifoil Kid - there's a bounty on his head. What's he wanted for? Rustlin'!

    Susiespearing, tony and PaulinM are right - you've been saved from a bad mistake. There are alternatives. You can get rid of your water tanks altogether - both heating and hot water can be mains-pressurised.

    Biff, what do you wear in bed then?
  4.  
    After moving to Canada, I must say that I don't miss the feeble water pressure that many UK hot water systems have. Everything over here is mains pressurized - header tanks would freeze in the loft and many houses don't have lofts anyway, preferring to use basements instead (which is far more sensible in my humble opinion). I'm happy to report I wear nothing in bed, except the occasional smile :wink: With air leakage reduced and drafts eliminated and a well designed forced air distribution system on the GSHP there are no hot or cold spots - everything is a nice even temperature and the system is as quiet as the hot water radiators I had in the last house I had in the UK - probably quieter as the heatpump is in the basement and really just sounds like a large fridge (which, essentially, is what it is).

    I do have a goosedown duvet though - actually two - a thinner one for summer (since we keep the bedroom temperature around 23.5C) and a thicker one for winter when the temperature is maintained at 20.5C (both are probably hotter than most people in the UK are used to). The reason other birds feathers are not used is I guess geese and ducks are also part of the human food chain whereas flying rats (sorry, pigeons) and other birds are not. Hard to be a vegan with a goose-down duvet.

    Paul in Montreal where we're having the warmest October on record - it was 25.4C yesterday with a nighttime low of 17C

    Is goose down a by-product of the foie gras industry?

    (Mind yer own business, Tom.)

    Thanks all.
    Ok so someone better start talking in english rather fast as I've now agreed to have a filler point and the tank moved right down the garden at even more expense.Yikes ! I gather that your suggesting I go for a couple of ASHP's?.Fostertom how can I have my heating and hot water from mains ? Please explain? Will this gain me brownie points with the hips survey or damn me to hell,as we are only here for another two years?
    I wouldnt dream of sleeping in some poor birds feathers.Wool blanket I should have said (renewable energy ,yes?) ahemm.

    Posted By: susiespearinghow can I have my heating and hot water from mains ?
    You don't need the small high-up header tank to pressurise your boiler/radiator (primary) water circuit, nor do you need the big cold water tank to supply and pressurise your (secondary) hot and cold tap water circuits. Either or both of these can instead take both their supply and their pressure direct from the mains. To achieve this for the boiler/radiator primary circuit you'll need some pipework alterations and a bright red pressure vessel, usually mounted near the boiler. To achieve this for the secondary tap water circuits, you'll probably need a new higher-pressure hot water cylinder, which will have its own pressure vessel and other gubbins attached. Any plumber will explain.

    Thanks Tom but we still havent established whats powering my boiler?
    Having looked at ASHP's they are not up to the task of providing full central heating yet.Even the industry association site suggests their use purely for heating DHW and possibly shop premises.Way too complicated and expensive to have a group of multi split units in a three bed house.This is where green technology falls down time and time again.Contradicting reports about what each system can and can't do and for every devotee of one method there are an equal number of people pointing out serious flaws.I came on here with around 8K to spend on a very ordinary house than needed updating so thought I'd try to do my bit if possible and go with new green technology.The truth is we are a long way off providing a reasonably priced ,easy to use,form of true central heating.Sad,but true.

    It seemed you've committed to oil, by having the tank moved? By going to mains-fed primary and secondary, you can get rid of both your header tanks and have an efficient (maybe condensing) ordinary boiler, not combi. Sorry, I've nothing to add about heat-source alternatives - others can tell you more? - but seems to me that you're stuck in the 'normal' solutions because no part of your plan is about seriously reducing heat demand or capturing solar gain (a bit of cavity or loft insulation, or otherwise merely ticking the HIPs boxes or complying with current building regs, doesn't do it)
  7.  
    susiespearing.

    Would 8K be enough to insulate your house so would not need central heating? If so then that would be Green!

    To not need CH, that has to read super-insulation, plus airtightness (otherwise super-insulation largely futile) plus then necessarily heat-recovery ventilation. That would work. Occasional emergency heat top-up could be by simple electric element in the supply-air duct - or by occasional woodburner.

    How many storeys - Is the dormered attic 2nd Fl? If that super-insulation can't go on the outside wall face, then minimum 75mm or more of sprayed hemcrete on the inside face plus a little way back, perhaps tapered, inboard along the party walls (or all the way for a boost in neighbour-soundproofing). At all costs avoid creating a lightweight-surface insulated interior e.g. by plasterboard lining over insulation. Let the interior 'see' the heavyweight walls. Roof shd be easy - but get advice on this forum, after more description of existing. Last priority is the lowest floor - again seek advice here.

    Windows - don't think of buying ordinary DG-trade or Builders Merchant windows - much much better can be had for similar money. Or with some ingenuity, possibly upgrade what you have.

    Your misunderstanding me fostertom.I wasn't planning on a "bit of loft insulation".To date we are looking at complete exterior insulation.Replacing all light fittings with energy saving fittings and bulbs,a composting toilet is planned.I already look at less use of resources and recycling is a way of life in this house on everything from building materials furniture and clothes.This isn't "just" about the HIPS,but I do have to take that into account.If you truly want the man in the street to take green seriously then sneering at any attempts they do make (however small) is hardly the way forward.I had hoped that there would be a real sustainable practicle solution to updating heating needs in a more enviromentally friendly way that was affordable for the average home owner.I havent got any boiler other than a back boiler at present and believe me if there was an affordable alternative the very last thing I'd be having fitted is a smelly old oil system,but as far as i can see there simply isn't.

    I think you have missed the point Tom and I are putting forward? We are talking about realocating your budget from supply (central heating) to demand side (super insulation, air tight etc) so you do not need to upgrade or install a heating system.
    see passive house specifications.

    Susie don't be hypersensitive - you're getting good advice here but you just seem to want a pat on the back. For a start, cancel the money you're about to spend on oil tank/relocation/concrete fence panels.
  10.  
    Sorry Jeff.
    I've read about the passive home but I dont believe that will work in an old property like this.I'm hoping that by insulating as best we can that will obviously cut down on the heating needed.solar would most likely take care of HW but I still want additional controllable heating.I had considered a stove with back boiler but due to the small areas of the rooms to find a stove to run a heating system would be uncomfortably hot.A neighbour went this route and its been a disaster.They can't stand to sit in their lounge.Log pellets boilers sounded the answer until I contacted a firm that markets them and was told that in reality thye arent ready for the domestic market yet in the uk and transporting the pellets makes them unnafordable at the moment.Trianco are working on an affordable air source heat pump boiler system but its still at the design stage.Electric heating is frowned on by everyone from the energy council to the man in the street and especially in this area where they built a new housing estate in the village supplied by electricity.They have petitions going due to the high cost they are paying in reality despite having been sold these properties as an economic breakthrough for non gas areas.
  11.  
    The relocation aspect isn't an option Tom.I have to go where my work states.I'm not the slightest bothered about a pat on the back.People dont even know i have an interest in trying to be green.I have read so many threads on here and the first few posts I think wow thats the answer!Then the negatives are brought up and its back to the drawing board.
    Sorry if i seem hypersensitive but when your reading and trying to understand something thats outside your direct experience and each site contradicts another it can be very frustrating.

    I think he might be talking about an oil tank!:bigsmile:

    I would try and get some local advice on the level of insulation you can install before deciding on what heat is required. Getting the demand side down as low as possible is the best investment.

    Yeah I meant relocating the tank! - you yourself are clearly rooted in your excellent terrace house. Maybe the info you're getting isn't really so contradictory - tendency to misunderstand what's being said - info overload perhaps. I'd go back to the beginning of this thread and re-read it - after initial explorative stuff, now all the basic info is there to do without oil or water tanks, boiler, rads etc. Maybe even your existing back boiler will serve you well, as part of an altered setup. It's within reach - you can be a prototype for millions of similar houses - true though that no-one, government/regulations, HIPs, building trade, has a clue that it's even possible - they just go on pushing half-measure insulation and more-of-the-same central heating.
