Would this be enough heating in our extension?

Extension on th cards starting in 2 weeks. Just realised my lovely pencil drawn plans have no radiators on them for FIL to put in to go with the existing GFCH!!

The extension is across whole back of 1960's house, single storey, 25ft x 14ft Width x depth, with kitchen at one end, living at the other.
We are putting 2 x 8ft wide Vufold concertina style doors (double glazed with low U value) and timber floors. also 2 large velux skylights in sloping roof.

How many radiators would we need to keep the place cosy in the winter??
With all the glass I only have 2 walls to put rads on and each bit of wall is only about 3ft wide!! Was thinking of thosefancy tall skinny ones.

I plan on stuffing the whole ext with as much insulation as poss in walls, floors and roof as want to make it a bit eco friendly, will heating be an issue at all really??

Anyone any ideas??
 
Re: Would this be enough??

Why don't you install a pellet stove - just a space heater would be simpler than a full boiler. That would do away with the requirement for rads and reduce your oil/gas consumption, even the most basic ones have a very high output and depending on your taste, there are some very contemporary designed and modern looking pellet stoves out there.

Other advantages include - they are C02 neutral, have a very simple flue installation, very clean burning and easy to maintain, many of them have a timer function so can be set to come on automatically. Also they do not heat up like a solid fuel stove so do not need to be guarded off from children. We installed one last year and are very pleased with it.

SEI will give you a €1,100 grant under their Greener Homes scheme, although I think most sellers have by now added that on to their price.

Re: Would this be enough??

Thanks for that Jake, Its funny as Hisband had really wanted one of these to being with and then the idea kinda slipped our minds, Saw a great one of TV about a year ago where this guy was making them himself from bits of old VW beetles and car parts Hot pods they were called, might have to look into it now s a surprise for Hubby,

I let you know how I get on

Thanks again for reply, what about supply of pellets or could you just use bits of wood??
 
Re: Would this be enough?

Apologies admin, will be more specific next time...

Hi Whistler, Don't have much skirting board either as don't have much wall space left after kitchen, ceiling to floor doors etc. Will look at the website anyway, might give me some ideas. They were in the house when we moved in , very old looking electric things that we ripped out!! I presume nowadays things are more advanced!

Thanks for the idea!
 
Re: Would this be enough?

When we had a look at pellet stoves, the minimum delivery was 3 tons. It was also necessary to have a dry storage area to store the pellets. Space is an issue with this type of heating. Larger stoves for full central heating had a hopper to feed the pellets into the stove. We would have had to build a double garage to accomodate it.
 
Howto heat my large extension??

Hi,
Had heard that the pellet ones need an extra house to store them in alright!! Seems a shame to have to deliver so much in one go.

I was thinking more wood burner where I just pop up the mountains for fallen wood every so often like I do at the moment for our normal open fire in the living room and that would heat the room nicely, anyone done this??

Would it give of enough heat along with the insulation to keep the place toasty??

You only need additional bulk storage space if you have a pellet boiler which provides your central heating, hot water etc. If you just have a pellet stove which just heats the room it's in, it will have a built in hopper into which you can empty pellets by the bag. There is an increasing number of fuel merchants selling them by the bag now. We installed ours last November and have never had a problem getting pellets. This is not the cheapest way to buy pellets but that's not why we bought one.

Details for the models that qulaify for the SEI grant can be found at

If you download the product list, there will be a web address for most of the manufacturers and installers, so you can do quite a bit of research. There is in general some very useful information on pellets and sustainable technologies throughout the SEI site.

You could install a wood burning stove, most models will provide brilliant heat for your extension (Most pellet stoves can only burn pellets). However the flue installation can be quite tricky for a single storey extension to a double storey house, as it must be brought up above the eaves of the existing house. This may also be expensive. The main reason we went for a pellet stove was because of the very simple flue installation. Another disadvantage is that a traditional solid fuel stove will heat up really hot so if there are kids around, it will have to be guarded off.

I have no vested interest in pellet stoves, but ours is fab, I can't understand why more people don't have them.

Hope this helps

Hi,
I never knew that about the bolier/stove difference. Very interesting but have also just read the post above mine about the pellets not being that available and there is only one supplier near me. Costs would worry me too, I think I d rather just burn bits of wood that are free, We would do alot of country walking and always come home with car load of old wood for the fire. I presume this is considered environmentally friendly, is it?? Kind of recycling, I think.
WE have thought about the flu bit as would have to extend the chimney part up above the eves but Father in Law is building the ext so thats not really an issue.

I think Ill go and investigate more...
Thanks so much for the helop at leats I have more options now. HAve also looked intot the skirting heaters too ut company is in UK, not sure if there is one here in Ireland which is a problem for parts and problems.
