Hello I have the Honeywell wireless thermostat with this receiver. Please see image below of the wires going into the Honeywell receiver. Can anyone confirm where I connect the cables on the Honeywell into the Nest Heat Link? I can see that I only have a connection at terminals A and B...

My apologies, I have just been and checked and the Flow/Returns to and from the 428 and cylinders are 28mm. I trust thats okay? I am not sure about the bypass? What am I looking for there?

Yeah I think I will just leave it as I don't have any spare tiles. Thanks for the reply!

Hello I have some plastic homelux edge trim and I would like to replace it with stainless metal trim or similar. Is this possible without removing the tiles? Has anyone done it? My thinking was to try and pull the old stuff out, but not sure if its worth it or not! Advice from anyone...

Perfect, thank you! The stuff they used is really rather thin - probably 9mm, so I will definitely replace it with the thickest I can.

Do you mean the pump, Dan? Do you know what the next one up would be?

The pump is a Grundfos Red Type UPS 15-60 130 p/n: 96281478 and it is set to level 3, maximum. Does that sound like an appropriate pump? It has to pump approximately 8 metres up from the cellar to the top room.

I do notice that the cellar is warm - the fitters definitely lagged the pipes but I am sure it is not good stuff! What thickness is the Climaflex Water Regulations grade? I see various thicknesses: 9, 13, 19 & 25mm - should I be using 25mm in the cellar? Unfortunately, they definitely...

Both cylinders are actually heated at the same time - they are connected together to make a total of 290l hot water, they don't supply a different zone, but they each have their own motorised valve. My boiler does enter anti-cycling mode when heating the hot water, I wonder if that is why. I...

Okay all is good rad wise - with the new radiators for the new loft conversion, we are still within 19k. The pipe runs on the system are huge, though, so I am sure that 10k will get sapped up by the long pipe runs between the boiler and the cylinders. The boiler is in the kitchen and...

As well as the rads, you may need to take into account the Hot water cylinder. If it's an old one, it will only use about 2kW. But if it's a modern rapid recovery, it can use 20kW. However that does not mean you have to add 20kW to the rad total to get the required boiler size. All you do is set...

Ah okay, thanks! I will go and check the Btus for the existing rads. The boiler is 28kw, so assuming that the radiator BTU's are less than 28kw (when converted to BTU) it will be okay? Is there anything else to consider? Will I need to increase the size of the expansion vessel? The expansion...

Hello everyone We are having a loft conversion carried out soon and we have a Vaillant 428kw boiler. Currently we have 14 radiators (incl 2 towel rails) of different sizes and we are looking at adding another 3 radiators (perhaps 4). Can the Vaillant 428kw heat this many? I remember when...

I have seen notes on a cold roof system on the web link (see below )I notice that it mentioned that sometimes cold roofs need ventilation and I wondered it if is possible to not have ventilation?: http://www.rooftechnology.co.uk/flat_roofing_insulation.html We are planning a cold roof deck...

Madness really. The thing is, when it will come to the neighbours turn to do it, if they have stung you, you are only going to do it to them. The only people who win are the surveyors. Ultimately, if there is nothing to stop you doing the work, I don't see the point in the surveyors other...

I do agree - I took out the bit about the paragraphs anyway, but I hope she doesn't dissent! Thanks for the help - much appreciated! :D

Thanks, thats great - I have seen that a few of the templates I have found online don't actually list the separate paragraphs so is it okay to do what they have done and say?: I hereby serve you with notice, as required by Section 3 (1), in accordance with our rights under Section 2 and with...
