So you have water dripping through your ceiling and you decide to ask a question on a DIY forum hoping for someone to give you a solution and you are prepared to wait for a correct answer, all this time you have water dripping through your ceiling, what constitutes an emergency these days?, try...

If you are just adding underfloor to one small area I fail to see the need to have a all singing all dancing system, simply addd a Danfoss RTL valve (Return Temperature Limiter valve) simple, easy, cheap and it works well, I would say putting wood on top is not best, you would be better with...

Is this a forum for DIY questions or an Agile advertising and work touting site

Here you go, you said about a CH pump immeresed in the bottom of the cylinder, I am just asking for you to give me details of a CH pump that does this, as far as I am aware they do not exist

You said that pumps can be used in the bottom of a cylinder submerged in the water and the heat can be extracted from the pump, so I have simply asked for you to show me one of these CH Pumps that can be submerged in water

Still not answered the question, show me details of an immersed CH pump

Johnsvill as usuall you avoid answering the question, can you provide the information on these thermal stores where the pump is mounted in the bottom of the store submerged in the water, to allow heat to be extracted from the pump, you are the one who says these exist, you are the one who seems...

I know he is Kev, just exposing him to everyone else, this is Dr Drivel, again, or what ever is last re-incarnatiuon was, he does this all the time, spouts absolute nonsense, but then goes very quiet when asked to provide proof, he disappeared from Screwfix when caught out when he used someone...

Johnsville, still waiting to see an example of one of these stores with the CH pump submerged in the water of the store to extract the heat from the pump, can you please give me the details of where I can find the information on this.

As usual, you preach this an that but cannot prove anything, I think it is you that is digging the deeper ditch, I am still waiting for you to show me a store where the CH pump is submerged in the body of water of the store, so please show me the evidence of such a store. Please don't try and...

I have no issues with thermal stores, I have fitted hundreds, but you are trying to rate a unit that you have never fitted, you are only relying on the sales stuff from the web site, just like a Google Warrior, this is a plumbing forum, not an engineers forum, although I doubt very much that you...

immersed pumps may be fitted in fish ponds etc, but these are low voltage pumps all pumps can fail, so how would you go about changing one of these pumps at the bottom of a cylinder, the blurb on the site is not what I call technical, its sales led, you are singing the praises of this store...

There is no technical info on this cylinder, just the blurb on the web site, I am not aware of CH pumps been immersed in the vessel water, never heard of it, sounds total nonsense to me, you are just taking what is on their web site, have you ever fitted one, what make of pump do they use...

CH Pump inside what

PHX will only lose heat when the PHX is in use, they are instantaneous, so they do not suffer from standing heat losses, so I think the heat loss saving is very small

I was gonna suugetrs exactly the same, ASBESTOS FIBRES!!! no one told me that when I was using the bloody stuff

"Facts of heat loss, efficiency, smaller packaging, etc" That is a fact that is stated by Nu-Heat, how many have you installed to prove that fact, what a manufacturer says to what the product actually does are two totally different things

Nu-Heat, not the best UFH in my opinion, so I would not rate their stores persoanlly. You go on facts, what sorts of systems do you install using Plate Heat Exchangers?

But as I have said all along that is not how a plate heat exchanger is designed to work, the exchange occurs plate to plate At the end of the day, you believe what you want and I will believe what I want, I doubt that either will change their opinions, but I have installed hundreds of heat...

"Having the PHX inside the top of a cylinder gives clear advantages. The whole of the plate is preheated by the mass of hot water." Really? how do you work that out, do you uinderstand the makeup of a plate heat exchanger, the mass of water will only be in contact with the outer plates and...
