Trafford Eco House

Our latest planning application is in – we’ve made many, many, changes to placate the council but have managed to keep the main elements that improve the house’s performance:

  • 200mm of external insulation
  • Extensive solar PV
  • Locally-made triple-glazed windows
  • A large thermal store, heated by solar thermal and a woodburner

Overall we’re still targeting a reduction in heating requirement of up to 95%, and to be a net producer of energy. All of this can only get built though if we can get planning approval though, and to date that has been difficult.

We need your help

We need to show that there is support for this type of sustainable building. We’re getting our neighbours to write letters of support, and add supporting comments to the planning application online – but the more we can get, the better.

What you can do – by November 27

Have a look at the planning documents, our application number is 81791/HHA/2013  and the documents can be seen here

If you have any questions, please contact us and I’ll do my best to get back to you quickly. If you’re happy then please send in a supportive comment. You can do that in three ways:

Online

The quickest way is to add your comment using the council’s online form with our application number – 81791/HHA/2013

Send an email

Or you can send your response to planning@trafford.gov.uk. Please be sure to include the planning application number (81791/HHA/2013), your name and address and your comments.

Snail mail

You can write to the Chief Planning Officer, but please be quick – we need all comments in by the 27th of November:
Planning and Building Control, PO Box 96, Waterside House, Sale Waterside, Tatton Road, Sale M33 7ZF

 

Please do what you can – we only have until November 27 to get comments in!

A quick update to my post yesterday on Woodburning Stoves for Heating & Hot Water in Smokeless zones. I’ve just had it confirmed by Rayburn/Aga that they do no wood-fired boiler models which are suitable for smokeless zones. So that means that I should update my Bin your Aga – buy a Rayburn post to “Bin your Aga and Rayburn – A Dunsley Yorkshire’s the only one for me”, and it means I can kiss my prospects of a Rayburn Solar Thermal System goodbye too. 

Maybe it’s time to move to the country 🙂 or look for alternatives to a wood-fired stove for my back-up water heating.

dunsley-yorkshireWe’re slowly narrowing the field in our wood-fired heating search. Following up on my previous posts on Woodburning Stoves for Heating & Hot Water and Using a Wood-Burning Stove in a Smoke-Control Area, I’ve found an interesting thing:

The Dunsley Yorkshire is the only stove with a back boiler that can be legally used in a smokeless zone

They cost £1922.30 for the wood-only version or £2218.40 for the multi-fuel.

So, if we’re looking at a wood-fired top-up to our solar hot-water that the sort of outlay we’re looking at.

The other consideration is overheating the house – if we succeed in super-insulating the house then having 4.5kw coming out of the Yorkshire into the room might cook us all! I’ll have to do the calculations, and look at how SIP and PassivHaus houses heat their hot water.

ecocamelJust seen the EcoCamel aerating showerhead – their test results claim a more pleasant shower with almost 50% of the water consumption of a standard shower. At the moment they are £40 for two – not the cheapest option, but a major saving if they work as forecast. Not only do you save water, but also they save the energy required to heat that water – assuming you’re not a devotee of cold showers! Potentially it could also mean that you ned to install less Solar Hot Water panels, which would be a significant saving!

solarthermal-300x225This sounds a bit too strange to be true, but it does appear to be above board. I’ve emailed them to check and we’ll see what the response is. 

Anyway, what am I talking about? Good Energy – suppliers of 100% renewable electricity – are just starting to roll-out a Renewable Heat Incentive. On this programme they will pay you 4.5p per kWh you produce. Don’t worry, you do not need to work out a clever way to trasport the hot water back to Good Energy – you can keep using the hot water, your bank account just gets an additional warm glow too.

Steadily firming up the shopping list for our new house – here’s the latest list, with links. 

Kitchen

Dining Room

  • Expandable table

Playroom

  • Instant-heat to stand in front of (Gas?)

Lounge

  • Wood-fired stove
  • Central Pendant light in diffusing shade – 12v CFL?
  • Two Standard/Reading Lamps – 12v CFL?

Garden

  • Kitchen Scraps Compost: Black Soldier Fly Composter / Worm Farm 
  • Firewood store, and at least 12m³ of wood
  • Greenhouse with Aquaponics system

Heating & Hot Water

Power & Light

Water

In my PassivHaus Renovation post I said that:

Any non-solar water heating to be Gas Condensing boiler or CHP – wood fired stoves are not permitted (this conflicts with my peak-oil resilience planning)

In return I got a comment posted by Andy Simmonds at the AECB stating:

The AECB standards do not proscribe wood stoves, nor does the german version of the PassivHaus standard.

I’ve been back to the AECB standards and here are the sections of the Proscriptive Standard that deal with heating & cooking:

Space heating (Silver Standard):

Normally radiators or underfloor pipes. Fed from SEDBUK A-rated mains gas condensing boiler, CHP or, outside the gas supply area, SEDBUK A-rated LPG or oil condensing boiler, earth-source heat pump (seasonal COP ≥3.0) or cleanburning biomass boiler; i.e, one using liquid or gaseous fuels. Wood pellet boilers are permitted outside the gas supply area but are not encouraged due to the exhaust emissions. Blocks of flats or maisonettes to have a central boiler and/or CHP plant or heat mains connection; i.e. heat distribution within the block rather than individual boilers or electric heating.

Space heating (Gold Standard):

Normally hot water coil(s) in ventilation ductwork. Circulating pump consumption ≤0.1 W per m2 floor area or pro rata; e.g., Grundfos Alpha Pro or equiv. Heat sources as for Silver.

Cooking (Gold Standard):

Hobs gas, LPG, electric induction or clean-burning biomass – liquids or gases only. Ovens gas, LPG or electric A-rated. Electric min. A+ or A++

I don’t see anything in there which suggests a wood-burner would be permitted? I’ll have a chat to Andy and see if he can clarify things for me!
