Oversized rads a good idea?

What about a boiler like this then, in an lean-to boiler house ajoining your house. A single skin concrete block boilerhouse can be built in 1-2 days???
Stick with logs mate, sounds like you can get plenty of good quality firewood. Sorry mate I'm not having a go at you or your poor girlfriend.

Thanks for the link.

The boiler looks great and I love the multi fuel thing - safeguarding the future and supply costs. Which is exactly why I am doing this.

Unfortunately, despite out rural location we are located next to a highway...a fork classed as a highway (to the back and side of our house), so planning would be needed. See this thread i started: //www.diynot.com/forums/buildi...ng-permisson-for-lean-to-near-highway.294390/

Of course I could get planning but it all adds to the cost and hassle. Not to mention the cost off the actual lean-to. We also dont have space for a large accumlation tank that I imagine would be needed for a boiler like this.

The other issue is that that boiler, although is a good price, doesnt seem to be accredited and also needs filling 2-4 hours on wood. Tht just wont work with our lifestyle. There's no my lady will fill it up during the day. The pellet addition could help.

Really we want an electricity solution or an exterior boiler of some kind.

Sorry i'm not making this easy.

Can anyone see how a water ASHP is possibly now looking like a sensible idea? Despite the house age, insulation and dreaded microbore!!

Here are some photos of the outside area of the back of our house.

Where the calor bottles and coal box are is a possible location for an outside boiler or ASHP. With a bit of clearing out and knocking out of a ledge.

Is there a way I could build an under cover area for a biomas boiler here that doesnt need planning. We have a highway both sides so planning will be needed. Maybe if it had a low roof that didnt connect to the house?

It's a semi, so the white vent on the wall is where the neighbours house is.

How water tight would the outbuilding need to be for one of those multi fuel boilers?

Here's another image of the gable end where I was thinking an outdoor pellet boiler would go. Just before the green shed kind of where the cylindrical compost bin is. There's a road to the left of the shed.

Any thoughts?

thought i'd reignite this thread with my current line of research.

Many have suggested in this thread, on the earlier pages, to go for an ASHP combined with our current ecotec 831 combi.

This isnt ideal as a big hope was to get rid of the boiler but its seemingly more and more the sensible option.

I'm still tempted by the DanFoss AQ with maxi controller.

I'm thinking of having this system installed with a 110ltr buffer with coil. Linking the boiler into the coil on the buffer tank.

Over the next year or so I can assess how much the boiler has been used and then decide whether to decomission and remove the boiler completely if the results are good.

What do people think to this idea?

I still say don't fit a ASHP, but draw your own conclusions;

Let's compare figures. 16panel array cost approx £12K generates £2k PA.
10 year running is £20k.8K in the black.
Solar thermal, £4K install,saves £200 PA, 10 year running £2k so where £2K in the red.

You are correct, PV panels will payback much quicker than solar thermal (installed by a pro), but that's only because of FIT, and who pays for FIT?

If I understand correctly, "it's the suppliers who pass on the cost of the Feed-In Tariffs scheme to all their electricity customers.
... so the bottom line is that people who don't install renewable energy systems pay for those who do!" see: http://www.fitariffs.co.uk/FITs/principles/funding/

But for a DIY Solar thermal install (I presume most who read this forum would consider DIY) the cost is nearer £500-700 not £4000. I plan to install an Evacuated Tube Solar Panel later this year, there are some interesting tips here http://www.solarproject.co.uk/index.html Makes me wonder how the pros can charge so much when solar thermal panels are relatively cheap?

The Guys at this site: http://www.builditsolar.com/ seem very pleased with their DIY solar thermal panels.

those panels are a bargain at that price with "free maintenance" too...I guess they will need that at those prices!

its down to quality.. most pros wouldn't touch that stuff with out decent guarantees and semi decent technical support.

solar in this country is very "installation sensitive" because we don't have much sun, as you may have noticed...

its never worth economising now to pay later which is what "cheapness" comes down too... decent solar installs will be around in many years but diy ones probably won't...

Please could you recommend a "Decent" Evacuated Tube Solar Panel? It's hard to tell what's good quality or just overpriced tat!

it really depends on the installation...in my book getting the design right is the critical thing then comes the manufacturer..

for some reason all my installs are evacuated tubes that have to be laid even vertical of horizontal ( I work in central london so planning restrictions are quite restrictive), so the viessmann vitosol fits the bill... in one I actually wanted a bit of inefficiency because of low hot water usage so I specified others...
