Hi, I always hear that wax trv are slower than liquid ones to response to temperature changes, so the question is: What is the average response time to temperature changes for A- liquid trv B- wax trv ?

And in a slightly different topic would anyone know if the honeywell vt15eg valve could be fitted with the honeywell vt117 or vt200? Are the 3 of them interchangeable by any chance or only the last two?

Doubting between Honeywell vt200 and the Drayton tr4. Any preference between those two? Tr4 seem to be a lot more popular in eBay.......

Hi. Sorry to resuret an old post but just wondering how you got on putting a drayton head into a Honeywell body valve!?

Hi all. Looking for a bit of advise. I have stove in the living room and then fire is on I wonder if it would be a good idea go fit a trv to the room radiator so it closes the radiator when x temperature is reached. What do you think? At the moment I have a condensed oil boiler with thermostat...

Looking for a bit of advice in brickwork. I have brick sills in all my windows. Last summer I decided to clean one of them with water and a hard brush. Whatever I did I am not sure if I screwed them up. They did get cleaned alright , although I think I discolored them at bit, but since then when...

The reason why I ask is the following. I had the glazing replaced in the 20 years old DG and also had a TG new window fitted in a garage conversion. I now suffer condensation in the DG but no signs of it in the TG. There is outside condensation in the TG but nothing inside. As opposite the DG...

Just wondering if internal condensation is possible in triple glazed windows since the the coldest point of a triple glazed windows is its litter pane. Hope someone can answer this question. PS. I know triple glazed windows suffer from condensation in the outside pane.

Yes there is a big price different. Retrofit would cost 75% less than going with new windows (in triple glaze). The retrofit guy tells me that my frames have a 24mm DG at the moment. He also reckons he could retrofit a 28mm DG Low E glass with Argon gas. If he is able to do that I am confident...

Hi, I have double pvc window frames. 20 years old and in ok conditions. Although the glass in many of them is gone. There condensation between the glasses and some are so bad that you can't even see through the glass. My options are: 1- replace glass in existing frames, or 2- replace...

Do you think that acid detergent could have taken a bit off the color of those brick? Would you just clean the other window cills and match them or let the weather / time do its work and they should all look the same in few months?

I used this fila concentrated acid detergent - 50% with water. http://www.tilecouture.co.uk/product/fila-deterdek/ Some photos before and after cleaning so you can see what I can. Before cleaning http://s24.postimg.org/7cfe7l08l/Before_Cleaning.jpg After cleaning...

I had the great idea to clean my bricks in my window cill and it looked like I took a bit of the red color off making it look brighter red. Is there anything which I could now do? Stain it? Seal? Water resilant? Anything?

Question. Looking to fit new windows (4) in the front of the house. Size around 2m*1.5m. I am looking for some 90mm insulated frames but I have big doubts whether to go double or triple glaze. The double glaze + frame would come around 1.2 U value and 1.0 for triple. The front house is...

Morning. Regarding the flow. I need to raise it 90mm. What is better option? 1- Flooring floor. Lay damp proof membrane + 60mm rigid insulation + 18mm tongue and groove chipboard. Or 2- Make a wooden frame with joists and fit rigid insulation in between it with chipboard or plywood on top...

Thanks very much for the info. Definitely something for me to think about. Now can I ask you for your opinion on my plan. Render the brick wall with non-waterproof render and then fix 120 PIR and plasterboard to the wall using mushroom fixings. I know this will not achieve the best U rate...

1) Sorry I meant between 120mm and 150mm. My criteria for perfection is U Value. This room is currently an attached garage to the house. It is very cold and built in single hollow block. Over the ceiling there is a roof. My plan is to fit insulated boards using mushroom fixings. 2) Outside...

Hi, I am converting an attached garage to a play room. Two quick questions. 1 - Rigid insulation to cavity block. What thickness? 120mm or 150mm? 2- Insulate only external wall or all around? Thanks.

I will take some photos and post them here.

1. Is the hot water supply from the boiler transferred to the cylinder via the pump. If not how does it get there? Yes via a pump which is located in the outdoors boiler case. http://www.warmflow.co.uk/products/boilers/k-series_he/kabin_pak_he_pre-pumped 2. How many cold water feed and...
