When I built my first house I went on a bicycle and the majority of my jobs have been within walking (long walk) distance.

Even tradesmen or professionals driving opposite ways round the M25 to work, or working in each others home towns when these are miles apart.

There is a business opportunity for a job swap shop? Both parties would save the time and travel costs shop could get a percentage?

Might seem a simple question but in the past we have built what was needed at the time yet many buildings are now millstones round our collective necks.

Should we build homes today with tomorrow in mind -- "Building for the Future"?

Are todays building standards and quality suitable for even half way forward into the buildings life?

What do you think and in particular what should we be doing differently?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=543 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=543 Wed, 08 Aug 2007 09:41:57 +0100 aberned
As a result, I have decided to change the heating system and would appreciate advice on what to replace it with. My thoughts are towards three potential solutions:

1. Ground Source - I don’t want to go down the road of installing underfloor heating so it would have to work with radiators (which I will have to buy anyway albeit 30% bigger). I have the space for a horizontal system, but rock could be a problem. Boreholes seem to be quite expensive.

My main concern is that I'm not totally convinced of the effectiveness of ground source with radiators and don’t want to go to big expense to be left with a solution that doesn't work effectively.

2. Air Source - to some extent I have similar concerns to those above regarding effectiveness with radiators. Another possible issue is that I am on the coast and suspect that the ASHP would be prone to rusting.

3. Wood Pellet boiler (self-feed). This is possibly my preferred option at the moment, although I still have to receive a quote. Seems to tick the boxes to some extent in terms of cost against oil and environmental impact. There seems to be limited information about wood pellet boilers (although I may just be looking in the wrong places).

The house is reasonably well insulated (Zone 1 - 32.8W/C and Zone 2 as 466.6W/C - not sure exactly how this translates - but most of the house is 'upstairs' with a games room downstairs). There is hardwood double glazing (not particularly clever, but probably sufficient), loft, floor and wall insulation.

I would appreciate any comments on any of the above or if there is a better solution that I might have missed, that would also be welcome.

Apologies for the ramblings!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=934 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=934 Sat, 01 Dec 2007 19:49:35 +0000 julie https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=930 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=930 Fri, 30 Nov 2007 18:15:43 +0000 jlogan

The Renewable Energy Institute defines a green home as a comfortable, cost-efficient, healthy home that significantly reduces energy and water usage and protects the environment.

Perhaps one might also argue with the science and the conclusions to one degree or another.
Set politics aside. This is larger than political parties or politicians. This is about surviving and thriving as families, a nation, and the world. It is about using economics and proven science to wage peace.
The alternative is the continued ravages of war for energy; a war which can only get worse before it gets better.
Replace the phrase “Global Warming” with “Peak Oil”. Peak Oil means that the world consumes more oil than it produces.
Peak Oil will cause the price of oil, gasoline, and natural gas to increase as the supply decreases.
Texas, for example, is a deregulated electricity state which uses natural gas to fuel turbines that provide most of the state’s electricity. What will be the effect on electricity prices if the cost of natural gas continues to escalate? Do you think prices for electricity will go down as fuel costs rise?

There are solutions available to everyone. There are State, and Federal Tax Credits available that will pay for, in many cases, most of the equipment needed to be Green.

A retro fit stove may not be the final answer, but it would be a simple, quick step in the right direction. We have a lot of fifty's council houses in this area and most have open fires with highly inefficient back boilers. The council is spending thousands, fitting cavity wall and roof insulation when all the heats going up the chimney. I don't consider central heating as essential, if the main room has a reasonable heat source and the house is well insulated.

Plumbers & heating engineers are rare a rocking horse poo down here so I am going to do as much as I can myself & get it sighned off before going live & will get advice along the way.

My 2nd problem is my Dads house, they spent 5k having an oil burner fitted 5 years ago, it was always too hot & they used to have the windows open with the boiler on all the way tough the winter as even set on the lowest setting it was too hot, they have since given up on the oil as they are skint & have decided to jump on the free wood wagon from my brother.

We are removing the old oil burner & they have bought a wood burner with a back boiler, they used to run about 3 rads off it aswell as hot water, my question is how easy is it to change them over & how & also would they need to replace the current liner which was fitted with theoil burner? I heard that they would need to change the tank in the attic to a stainless one, is that right?

any help or advice on these would be very welcome.

Anyone feelings on massiveness in radiator heating systems. Following on from the discussions on high or low mass in construction and the debate between UFH and radiators (assuming you need these of course).

I was thinking what are the differences between low water content Steel or Alu radiators and the more volumous cast iron or steel column radiators. The bigger the water content the longer to run upto temp, but when the room stat/TRV/timers switch off the water contained within the unit has more heat to dissipate to the room. Greater thermal inertia.

I was trying to see if one or the other was more or less suited to a relatively well insulated situation as compared to not well insulated Victorian pile, but couldn’t decide whether fast heat up was more or less desirable in either situation, or if the faster cool down was more of a problem in either.

In the colder situation fast warm up is good, but as heat losses are higher the cool down will be quick too. So I thought higher mass, but you’d be colder waiting for the warm up. It’s basically the UFH argument again I suppose.

Any thoughts – just interested.

I was looking at this to improve insulation/condensation proofing in difficult areas. Its flexible so can be pasted to curved areas. That was why I was looking at it. I have recently come across a number of curved areas that span across rooms in roofs, and are otherwise inaccessible. Also alongside some narrow stairs. However, the only retail price I could find seemed to be very high. The U value isn’t that good (although I believe the product is good for sound deadening) it looks like the stuff yoga mats are made of.

I discovered that the thin 2mm thick paste on polystyrene is still available, 2 layers of that has the same insulation as the 5mm sempatap (not much I grant you – but everything helps).

Isn’t this polystyrene stuff a fire hazard? I didnt think these types were still available.
Are there any other very thin flexible materials that can be used?

Please don’t suggest rip it all out and start again, I can’t make the oldsters live in the garden till next Easter, even if they could afford the job

I have installed and tested a low cost woodstove adapted to make it clean burn and added a carefully positioned back boiler. The back boiler feeds by gravity into a thermal store from which mains pressure hot water is generated via a plate heat exchanger whenever the store is above 50C. If below this hot water is heated by my gas combi boiler as per usual by switching solenoid valves. I have now added a second plate heat exchanger to feed heat into the gas central heating circuit which is enough for three rads. My gas use is now down by 80% as the wood is free! and I do not require heating in kitchen were the stove is and in the room next door. I reckon the cost of the whole install was about £600 using as much eBay parts as possible and pluming it in my self. I have an option of solar input as the tank has a standard coil in the lower half.

· Are you planning to renovate your house and want to do it in
the most environmental way possible?
· Do you want to slash energy bills and make your house warmer,
brighter and healthier?
· Are you selling your house and want to improve its poor
energy rating?
· Do you want to prepare for life in the climate change century?

18 eco-houses in Oxfordshire (14 of them in Oxford city) are opening their houses to the public to share the techniques, products and possibilities of eco-renovation. This is a superb opportunity to see a wide range of approaches and talk to the house owners directly about their experiences.

The houses cover a wide range of challenging types -including a garden office, a flat, a former council house, a terraced Victorian house, a 17th century cottage in a conservation area, a listed Regency villa and a 1980's developer house.

All of them have dramatically reduced their energy and water use. Some have used standard materials that could be bought at any builders merchant. Others have used new technologies including straw bale and sheep wool insulation, solar panels, wood burners and a heat pump that draws water from the Thames.

I live in Guernsey and it is pretty damp here the whole time. Alot of the houses are old granite ones and the traditional approach was to have an Aga running to keep the perceived moisture levels down. I grew up with them and love them...

However, I guess that they are the car equivalent of a 4x4, guzzling oil like nobodies business.

My gran has an electric one (Economy 10 or something) which is a more indirect way of using fossil fuels (no direct personal combustion), but still pretty bad for the environment. I think that the local electric company is looking at a tidal solution but that will be a while away.

Anyway, it got me thinking. My gran's Aga is much like a very large night storage heater - a bunch of bricks that heat up and store energy and then release it for cooking.

Surely there must be a way to heat up that amount of bricks (or whatever the material inside is) to the correct temperature by solar energy? Would PV panels work or would you need to use some kind of evacuated tube/water solution?

As you can see I am blissfully unaware of all the details but hoping to find out alot more about solar power in general (will post another thread on that). So if you are more practical in this area please let me know if this exists or is possible or even is desirable.

We're buying a house in the north of England, 1000 feet up in the Pennines - a mix of solid stone and cavity insulated walls, about 190 square metres. Currently it's heated by a coal-fired stove powering radiators, and that's going. Question is, how do we heat water and space.

GSHP impossible due to configuration of land. No mains gas, obviously. Planning permission unlikely for solar panels (we're in an AONB). We looked at wood-burning systems, but we don't have anywhere to season wood, and the level of hard labour required makes it impractical. Wood pellet systems are prohibitively expensive to run. So we were thinking that, like everyone else around there, we were going to have to fit an oil tank and have done with.

Then we came across this business of _air_ source heat pumps. What we're thinking of now is the following:

- Panasonic make air-to-air heat pumps, which they claim blow warm air around your house enough to heat it adequately. I've used air-duct heating systems in the US and have no problem as such with them. What makes me nervous is (a) their claim that one or two such units can effectively heat a whole house; (b) are they going to make so much background noise that I go postal; (c) can they really extract enough heat from the northern English air? They claim that they can function without backup as long as it is more than -5 degrees outside, which (if true) covers enough of the year to be able to manage with a wood-burning stove and electric radiators for the rest of the time.

- And the 'Altherma' system which is being marketed in the UK by Daikin claims to be able to use an air-to-water heat pump to be able to provide domestic hot water, with an immersion heater backup for heavy usage / very cold weather. That seems more straightforward, but again I don't really know if it can do what it claims. Nor what it costs (they are very cagey about that).

All this seems very appealing, both in carbon-footprint terms and in reducing running costs. And since I have to shell out to fit a new system of _some_ kind this year, it seems an obvious opportunity. But I am nervous about being an early adopter of something which is obviously very new in Britain.

Can anyone reassure me, or warn me off?

Option 1; Underfloor heating running off a wood burning stove with back boiler.
Think we need an accumulator and pumps - concerned that pumps may require too much electricity given we are not on the mains and don't yet know how good a wind site we have here.

Option 2; Pumped radiators running off a wood burning stove with back boiler.
Don't need an accumulator but still need a pump, same concern with electrical requirement.

Option 3; Thermosyphoning radiators running off a wood burning stove with back boiler.
No pumps required but due to restrictions on all pipes [min 28mm copper] needing to rise along their entire length from boiler to radiators it is not possible to have radiators in some rooms without pipes crossing in front of windows a few feet up and having a couple of radiators half way up the walls..

Option 4; Two wood burning stoves without radiators [well one would have a back boiler for heating domestic hot water and would have a radiator for pressure relief]
Nice and simple to install but will the heat percolate through the rooms enough? Building regs require us to put sound insulation in the internal walls and we are worried that this could prevent heat moving from heated rooms to unheated rooms.

Where the pools become very big and the shape is very freeform and 'pond-like' it seems a little overboard working like this, especially if the soil is quite hard and cohesive. Gabion walls must be a good option if their is a lot of hardcore onsite, or crushed rock available locally if there are aesthetic concerns. I have considered many of the modular precast systems. One of the best ideas seems to be precast concrete L- blocks, which are very quick to assemble and good for walls with curvature, but use a lot of heavy machinery and are still made of concrete.There must be some clever systems using the soil itself, such as filling recycled tyres, however the surface of such a wall is very irregular.

"Announcing the Green Homes Service this morning, environment secretary Hilary Benn said: "When it comes to cutting your carbon footprint, the old adage 'there's no place like home' really is true.
"We need to make this as easy as possible for people to do. There's a lot of help out there in the form of grants, advice, and other assistance, but it’s hard to know where to start."
He said the new-look Energy Saving Trust would act as a one-stop shop to extend the use of renewable energy at home and improve efficiency.
The government wants 150,000 homes to be generating their own renewable energy by 2011, but recognises householders will need government help to meet this goal.
Mr Benn continued: "The Green Homes Service will cut through the confusion by providing a one stop shop, including a green MOT for your home and a green home makeover."
Housing minister Yvette Cooper is also backing the initiative, which launches on April 1st 2008. "]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=879 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=879 Sat, 17 Nov 2007 09:05:53 +0000 biffvernon
Looks like they're spelling things out a bit more clearly this time.

But Oh Dear! Look what the Grauniad has found:

What is the best way to feel these holes and stop the loss of heat and draughts from below into the loft space?

I am installing an Ice Energy heat pump running underfloor heating and hot water and want to integrate
a wood burner with back boiler to run 5-8 rads and provide hot water back-up.
Two initial questions:
1) Does anyone have technical plumbing information for this kind of set-up?
2) Does anyone know if the HWAM Classic 4 stove is capable of taking a back boiler?
I'm trying to find a boiler which is utility/contemporary in style but with the boiler option....
I'm trying to avoid the traditional looking boiler such as the Charnworth......

How best to deal with this attractively?!

No screeding has been put down and I was wondering if anyone could add their comments to an alternative idea I have to screeding my floor.
I want to lay 50mm celotex/kingspan floor insulation between batons spread at 450mm wide intervals. Onto this I wish to nail 18mm solid oak floorboards. The new concrete floor already has an insulation slab and DPM as to current building regs. I'm hoping this idea will eliminate the higher cost of screeding and also improve even further the insulation properties of the rooms. Would appreciate any comments you may have.

240m2, reasonably well insulated, retaining 16 radiators.Considering an Aarrow Stratford TF90 wood stove (24kw water / 4.5kw room) and a 350l Gledhill 'Torrent RE' thermal store and 2x Navitron 20 tube collectors (in the spring time), with an ageing Worcester oil boiler as back up.

Going to speak with manufaturer's and my green plumber friend who'll be helping, and who's open to experimentation, but would appreciate any other comments / ideas to put on the table...

My first question's going to eb whether the 24kw stove rating (intended for a primary pumped heating circuit?) is suited to the store size / strategy, next will be controls / thermostats / designs to set an alarm clock off when store temp is falling towards an oil boiler firing, giving time to stoke a fire up.

Saw a 1500l accumulator tank for sale on a thread here & got me thinking about strategies to store enough hot water to only power up the wood burner sparodically (say alternate /3 days in deep winter?)]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=875 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=875 Fri, 16 Nov 2007 03:02:53 +0000 Terry As a popular cladding presumably durability is ok, but what about movement or any other issues with cedar in this application?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=688 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=688 Sun, 23 Sep 2007 20:46:30 +0100 pdurkan@yahoo.co.uk 1 - Use "wood"-coloured silicone sealant
2 - Use a mixture of wallpaper paste & sawdust
3 - Use a product called Rubio mono-coat(?)
Has anyone tried any of these? Good or bad? Or can you recommend something else?

Cheers
