Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.

Forgot your Meds again eh Dr Drivel?? C'mon you auld git fess up it is you. Where have you been, have they had you under full sedation for a few months??
Your threads are like Deja Poo; You know you've heard the same old sh.te before.

Oh use the saying at will Onetap, I've got a million of em....
The fun has started already!! I hope his Nurse doesn't visit him again for a few days, we'll have a right laff!!'

Here are some interesting youtube videos for you.
As I explained in my first post, you can dispense with a thermal store when fitting UFH by fitting a small Geminox 0.9kW to 10kW boiler heating only the UFH. DHW is via another means such as: a cylinder & small boiler, combi acting as a multi-point (or supplying rads as well), DHW only small thermal store heated via a small boiler, cylinder with an immersion, etc.
In one installation I kept the existing boiler and cylinder and cut off the rads and had the boiler heating DHW only. The new separate Geminox boiler only did UFH. A cheap quick and highly effective solution. The customer was expecting it all to be ripped out and replaced and was pleasantly surprised when a quick, cheap, solution came in.
Cost each setup and see which comes out cheaper. Glad to help. I am off to work.
It's so amusing to watch playground arguments
But if you are going to claim the high ground, then you really ought to at least try and hide your own hypocrisy - you slag off <someone else> for having set opinions on certain topics, but give the impression that you cannot conceive of any valid use case for certain things you dislike. See if you can think of a well known phrase involved pot, kettle and the colour black. <someone else> may well be trolling something you don't like, but you aren't much better when it comes to being open minded.Apart from the cost, there are many things in favour of a thermal store or heatbank. For one thing, it means you can completely eliminate the inherent incompatibility between a decent sized boiler and a moderate sized heating system (which is made worse when grossly oversized combi boilers are fitted to supply hot water).
If properly setup you should be able to get a thermal store or heatbank system such that :
The boiler is always condensing, and never runs in short cycles - though this is made harder to achieve by **** poor design on the part of the boiler manufacturers.
The heating system can run quietly with variable flow rate (fully modulating pump is great for this).
Running multiple heating systems (eg rads and UFH in different areas) is trivial without cross interaction.
Hot water is available on demand, at decent flow rates* and at mains pressure*.
You can have an electric backup for hot water and heating for when your new and horribly complicated boiler breaks down.
* Yes, that's subject to mains capacity - but that's the same with a combi which seems to be very popular.

Thermal stores, rightly, got a rotten reputation in this country due to poor specification and design..and in part being a way for a specifier to save a few pounds...with a correspondingly poor installation
we would do well do adopt a different vernacular, buffer tanks for uncontrolled heat sources.
Thermal stores do work with condensing boilers, but poorly. Thats in part because high temerature themal stores dont really exist out if the UK...
In energy efficiency terms what is the point of over heating water to bring down the temperature to usable temperature...much better to minimise wastage by specifying a product that designs out waste...ie unnecesarily high temperatures...

They also help make TPi controllers super efficient when hooked up to a TS - something I know gets a bee up several poster's backsides .
Bit like a certain someone slagging off the CC, but then bleating on about wanting to get back in
A TS is a nice way to mix underfloor heating and rads, and condensing boilers. Granted the condenser has to work harder to top up the hot water section, but it certainly condenses the whole time.
How do I know....? 'cos I have one.
Still trying to find the time to jam a camera inside to see all the wonderful sludge from my microbore heating system , but the longer I leave it, the more there is to build up I suppose .
The only thing I will add though - make sure you lag the pipes and tappings, otherwise the standing losses can be a bit annoying.

I'd call that a buffer tank Dan..for integrating varying loads...
Alec - I have a firking great PHE on the side of mine.... Top of cylinder gets to 82 ish. Controller switches boiler off at 52.
Only thing with adding WC is to use a 4 pipe boiler and separate control set. Which makes the install cost and complexity not worth it for mortal man. Stratification is also an issue I planned on researching as my unit doesn't have any baffle arrangement.
DIA.... not a drop of inhibitor in mine
Don't believe in the stuff.

I'm gonna cut a hole in the tank when I come down in July
Thinking about it, the doc may let me borrow the endoscope for the weekend.
I al;ready ahve an endoscope... need it to find the cash in my wallet after having to pay for the running of my TS .Alec... How hot do you need to run a boiler to generate hot water? Why is a TS system less efficient?
I could limit the boiler temp to 70, but then i need to deal with slow ramp up rates of boilers. When a boiler is in hot water mode (like your beloved Viessmans and Vaillants) they will also be cranked up to 80 odd degrees. But then I will need to reduce my flow rates off the PHE.
But once it is nicely lagged... I remember posting my TS skin temperatures a while ago... you chose not to respond .

nothing to really to respond to...there wouldn't be any standing loss if the heating was off as the boiler would be off!
with a TS its is always waiting at high temperature for a call for heat...although in summer you may heat less of the store...
