Advice needed on heating new room

wexford12

Hi im looking to get some advice on heating a new livingroom/diningroom we are adding on to our kitchen.The room will be 400sq ft we are putting in 2 1200 radators do you think this will be enough to keep it cosy.We would like to put in a fire ie gas/elec but cant find a really nice elec one and most gas ones need a flu which is working out very expensive.Also the build cost is working out about 59euro per sq foot is that about right do you think.Iv been amazed how hard is has been to get a builder to quote for the job we have a floor plan but not drawings for roof etc its a very simple L shape room.Any ideas for savings or tips on the build would be great. Thanks

What do the drawings say about insulation in the floor, walls and ceiling. What area of glass will you have and what direction NSEW will it be facing.

Double or single rads?

Would be a great space for a standalone pellet burner.

Without being disparaging about the build quality that can be achieved in a €59 sq ft extension it is unlikely you are going to be getting top end insulation or windows/doors.

Sorry it will be 2 double rads one is 1000 and other is 1200. the wall can be either pumped beed insulation or a board type he has given me the choice. roof will be 300mm insulation also.The windows are Senator A rated and there will be two corner windows 1500mmx2 each side of extension ie 10 feet of glass in each corner + 2 french doors 1800mm each the build faces south so one side will get morning sun and full sun mid day and evening sun to the other side.Hope this makes some sence any advice would be great

Firstly the price of 59 sq ft seems very good. I would go for the pumped insultation unless you are in an exposed site. 300mm would be a minimum.

Can you do a rough sketch in paintbrush of the layout. attach that to the post. Need to see the layout as position of rads will be very important or else you are going to get cold spots especially with that much glass. An A rated window sounds good until you compare it to a standard insultated wall. The wall will perform at least 6 or 7 times better at keeping in the heat.

Remember south facing is great in spring/autumn sunny days with say a standard window. When you have a lot of glass the room can overheat and especially so in summer. Then on the gloomy days (a lot of those recently) you will have zero solar gain and maximum heat loss through the doors especially.

This might help regarding the resizing of images to be uploaded.

If you are using paintbrush save as jpeg and NOT bmp.
