Yes, its just trying to keep with them all. I would rather be in the garden in the evening than reading the latest technical specs on a worcester-bosch boiler.

I hear that! Get out in the garden while it's nice.

Which is the most important the wattage or the BTus is a double panel better than a single panel?

Many thanks

Which is the most important thing to look for when buying a radiator the wattage or the BTUs? Is it better to buy a double panel radiator rather than a single panel radiator.

Many thanks

You need to work out the BTU requirements for the room and buy a radiator to suit

[JBradleybz]

I would carry out heat calculations of the room first, measure the length then the width and the height i like to do this in feet.
Then go online there are loads of heat calculators for the uk just enter it into google and you can work out yourself what BTUs (British thermal units)are required for the room your checking.
Doubles always tend to give more BTUs, im glad your not going for the underfloor heating ive worked on it lots years ago and i dont rate it at all even more so when its older.
Any more advice needed we are here just ask cheers jon.

It's a big room of about 30 m2 so need 2 radiators really, the problem is we bought a square tube designer radiator for lounge and it says over 7,000 BTUs but it never feels very warm to me. These ones have got to warm up as its a big room.

Thanks

Hi posted on your other radiator thread cheers jon.

[leelister6]

Your room requires approx 14,000 btus. Two 600 x 1200 K2 rads would probably give sufficient heat

[Designzilla]

According to the calculator I've just used I need 18,800 BTUs but only got enough room for 2 radiators so it's going to have to be a lot less

[JBradleybz]

You probably have worked out different due to fine details such as north facing walls, double glazed windows, french patio doors, plus how many degrees C temp rise your wanting in each room.

If you used an online calculator then there are several, and in my experience they all give different outputs. It is a large room but seems cotrary to suggest you do not have sufficient room to accommodate big enough rads?

Many thanks

Electric under floor has its limitations and is costly to run. Not bad as a tile warmer in a bathroom but would stick to wet underfloor heating systems anyday of the week.

Regarding radiators, you do indeed need to carry out a fabric and ventillation heat loss calculation for the room first. This will tell you what the total energy loss for the room is and the required heat input to meet the rooms design temperature. There are basic calcs online that will give you a rough idea of the output needed from the heat emmitter i.e. radiator.

Towel rads tend to be limited, and chrome rads kick out even less heat than their equivalent white ones.

Id check out Stelrads online product range as they will have the widest choice.

Happy to advice further if you wish to email me speacock@greenbuyenergy.co.uk or you can always pop into out high street showroom in Doncaster (near Frenchgate) for a chat.

If you email me a sketch of the room I will do an accurate fabric & ventillation heat loss calc for you.

I will need the following information to be able to carry out the calculation...

Room type i.e. living room, kitchen etc

length & height of each wall including what the wall is made of, and whats at the other side of that wall

eg Dimensions: 3m long x 2.4m high, Wall construction: Cavity wall with insulation, Other side of wall: Outside North facing.

If there is another room at the other side of the wall, then I need to know what that room is,

eg Dimensions: 3m long x 2.4m high, Wall construction: Insulated timber stud 100mm thick, Other side of wall: Kitchen.

Make sure you indicate any windows or doors that communicate to outside, and give the dimensions. I also need to know what type of door or window it is i.e. single / double glazed, what the frame material is, i.e. UPVC, aluminium etc, and the thickness of the glazing.

I need to know what the floor construction is i.e. suspended timber, solid etc.

I need to know what the ceiling construction is and what is above that ceiling i.e. another room and what type of room that is.

few... nearly there I promise.

I need to know your geographical location (just the street name, and town will suffice, or area if you prefer not to disclose). This is to obtain the outside design temperature for your area.

Are there and chimneys or open flues in the room?

I think that should cover it, but as you can see, an accurate room heat loss calculation is quite in depth. Its not difficult to do, the hardest part is getting all the above accurate information

My email is speacock@greenbuyenergy.co.uk

Kind regards

It would be best to plan from the house rather than the products. Everything depends on your heating situation and then find the solutions.

Does anyone have experience of having their central heating system power flushed? was it messy? was it successful? who did it? Thanks in anticipation.

We had our central heating system flushed by British Gas ... took about half a day (5 bedroom house), included having some additional filters fitted. Fixing of any 'leaks' along the way were included in the price. No mess, and it appears to have benefitted our aging system: radiators get warmer quicker and appear to radiate more heat. Cost was around £700 I seem to remember.

[WasThatWise]

had this done by British Gas about 3 months ago, it was deemed necessary because of a hot water problem and took about 7 hours at the promotional rate of £599, no mess but nearly didn't go ahead as you need to have an open drain not in the road that they can use, luckily neighbour let me use his. Unfortunately it wasn't the cause of the hot water problem which reoccurred a week later and was a diverted valve problem. Think radiators are hotter, not sure am using less gas though. Various valves and filters and rerustproofing with fernox and a new pump were included in the price.

[jaycee331]

Was it BG who told you it needed Powerflushing?
I just say this because they do have form on telling people they need one when in fact a chemical flush would suffice for quarter of the price.

I was once quoted about £700 from BG too. You will find a good independent plumb will charge around half that.

So yeah I nearly had it done as BG insisted it was needed. I hired an independent to check it out and for £300 I had a chemical flush done and a Magnetic filter installed, and everything has been just fine since. LOL BG wanted £300 just for the filter+fit alone.

BG are generally twice the price of an indy. But some people will pay that for peace of mind and guarantee backup from a firm you know won't disappear overnight.
