Hi, Earlier this year we had to shut off our main kitchen raiator as it had started leaking; the leak in question was from the bottom of the radiator, partly underneath and more or less in the middle. Inconvenient but still... This week we've had another radiator go in exactly the same...

Hi, As the cold weather draws in were looking at ways reducing draughts and keeping as much heat as we can in. Our living room, a typical semi-detached, one external wall type has 4 airbricks in. 3 at ground level (bottom left, bottom middle & bottom right) and 1 in one of the top corners...

Hi, In picking a new radiator for a room, I've noticed that BTU figures seem to differ considerably between sites and manufacturers. As an example, a Double panel 1000w x 500h panel from B&Q (Kudos brand) states 1.476Kw whereas from Homebase (Quinn brand) stated 1.662Kw - a difference of...

The radiator I was going get in the new year is wider and taller than the current one - I did say the previous occupier didn't have a clue. If it was a case of just buying a radiator I'd buy it now rather than faff about. Thing is the pipework needs to be altered and so the fitting cost would...

Hi, Recently we've noticed that one of our radiators has started leaking and upon closer inspection we've found that the leak is coming from the bottom of main panel of the radiator itself - as if it has been knocked by something. This leak is tiny, most of the time you can't see it...

Whilst I agree with what EST states now, earlier this month it had an online wizard that stated what I put in my last post instead. This wizard appears to have been pulled in the past couple of weeks (I wonder why) but I did print each page of the wizard to a PDF file when it was live, so I...

Hi, We recently had our back boiler and accompanying fire removed as part of a heating system upgrade and what we would like to fit in its place is a quality wood-burner 'effect' fire (be it gas or electric) - think cast iron Broseley/Aga as opposed to tin can Valor/Dimplex. The thing is...

I think the engineer at the time took me literally, I didn't know there was anything up the chimney and therefore couldn't ask for work to be done that I didn't know needed to be done. Going forward, we're either looking at putting either an electric fire or a gas fire in its place. We...

Excuse me but if you look at the EST calculations for external wall area they are: - NoOfExternalWalls x (Length + Width) x RoomHeight x NoOfFloors Now I don't need to be a heating engineer to understand basic maths here but "(Length + Width) x Room Height x NoOfFloors" = the area of two...

Hi, Having had a back boiler and accompanying fire removed (one of those fires that won't work on its own) we've looked at what we are left with and you can see what appears to be a flexible spigot (that was attached to the old boiler) that runs up the chimney surrounded by insulation -...

"Where do you expect the other 10 Kw to go to? " I did say excuse my ignorance.

Ok, excuse my ignorance here but firstly, what is the benefit of this (let's face it, although heating systems are designed around specific temperatures - eg. 21° in living areas - I, as a user might want my house to be a lot warmer and therefore use more Kw). Secondly, would there be anyway as...

Hang on a sec, what does "range rated" mean and once installed, how would I be able to tell how this was set? Sadie.

13½Kw was worked out from the Energy Saving Trust 'whole house' calculator, but going through the figures I think a few of it's screens are out or misleading... which is a little disturbing. Using the SEDBUK whole house calculator, the calculations come to 8.5Kw heat loss plus 2Kw water...

Hi, We have a small 3 bed house (by small, I'm talking 17' x 23' x two floors, no dining room, no ensuites, 1 of the bedrooms is barely big enough to fit a bed in), and using conventional wisdom (ie 'system' boiler calculations) this equates to 13½Kw of heating plus 2½Kw of water heating or a...

Woody... Trying to insulate the house as much as is reasonably possible. Etienne247... Thanks, I'll take a look Sadie.

Deluks, Care to give me some more information on insulated backed plasterboard? info links, effect on U values etc., PJ1. Sorry, we've got solid walls, no cavities to fill. Now bearining mind that we have a small 1930s semi, that we cannot really afford to lose 2" off each rooms...

Hi, Has anyone had any experience of Warm-a-wall internal wall insulation. It appears to be one of only two products that the EST recommend for Internal Wall Insulation (the other being Sempatap Thermal). Unlike Sempatap however this (warm-a-wall) needs to be skimmed before use and as...

Having done a little research on floor U values and feeling a little out of my depth on building terms ("cold bridging"..? What's that..?) I thought it was time to step back a little and check that I am not using a sledgehammer to crack a nut. Just to put this into context; Considering that...

Hi, I had an idea re the above and could do with some feedback as to whether I am completely barking or whether this is a sensible suggestion. In our house we have suspended wooden flooring on the ground floor and B&Q (ww.diy.com) are currently doing top-up loft insulation (200mm) for £9...
