ACV cylinders

[jon26]

Anyone had any experience with the ACV cylinders, how do they compare with other. I hear the re-heat time is much quicker?

Much cheaper and far faster reheat using a direct cylinder, a plate heat exchanger and a bronze pump. Also condensing is guaranteed for 90% plus of reheat.

Customer support lousy, product very good.

Why are you always pushing the thermal stores. Ive never come accross a plumber that prefers one over an unvented indirect cylinder, wouldnt touch Gledhill with a bargepoll

I did not describe a thermal store, it was the fastest way of re-heating a cylinder..and the cheapest too. What didn't you understand? BTW, there are a number of ways of re-heating a cylinder besides using a coil, which is about the most inefficient.

Plumbers are best doing drains. I find few understand thermal stores - as you have just overtly displayed. If they did they would not fit silly unvented cylinders and directly heated rads meaning auto by-passes which invariably open at too early reducing condensing efficiency, centralised wall stats and lots of inefficient boiler cycling. Thermal stores are far superior to other systems...by a mile. Anyone who understands thermal system would know that. Read the thread "Heat Banks". Look at the posts describing performance near the end.

Highly cost effective and unsurpassed performance.

Used more on commercial systems but can easily be applied to domestic cylinders.
I only know one plumber out of about half a dozen in my area who sets his systems up this way. Very highly sought after plumber and his pipework is perfection, but you know when you have him in your gaffe as he ain't cheap.

This describes it better:
http://www.mcdonald-engineers.com/products/plateflow_specs.htm

A plate heat exchanger is about £100, a bronze pump around £50:

The cylinder can be downsized saving space, and no internal coil, so savings there. Overall it is cheaper and a far superior way of re-heating a cylinder.

Unvented:
A Santon 100 litre direct is £433
A Santon 150 litre indirect (equiv of above in DHW delivery) is £589.15

Also the plate heat exchanger can be screwed off for descaling - a DIY job. And you never run out of hot water.

When installing 300 litre cylinders using this plate heat X and bronze pump it knocks a fair bit off the total price. Using the plate a 200 litre cylinder is equiv.

300 litre indirect is £760
210 litre direct is £533

£230 less - an for a far, far superior setup all around.

BTW, this can equally be fitted to a vented cylinder too.

Sounds like you only have one decent plumber about your place. He sounds like excellent value. His craft skills aside, he obviously technically is on top of things and gives the most efficient system. That is cheaper in the end. Most plumbers only know what the man at the counter told them, so buy that.

The only drivel is what you just wrote.

I take on board your comments... but answer this. Why do unvented cylinders outsell the heat bank (thermal store) type cylinders by about 50 to 1 ?

And the unvented's tend to be slightly more exensive, as you have already mentioned. Why are they not in every house, the unvented cylinders are so much more popular.

It was around 10 to 1 the last time I looked.

Unvented cylinders sell because of ignorance by installers and also they get an annual service charge from one.
Look at this thread. Not one of these posters has the remotest idea of what they are on about. The distinct lack of knowledge regarding thermal systems and thermal layers is disturbing:

Look at this thread "Heat Banks" on how an integrated heat bank is put together. An amateur DIYer figured it out and bought one to order. He put to shame the so-called professionals on this forum, even doing so tests on how it performed, noting return temperatures that promoted extensive condensing efficiencies, which was impressive (Not to be disparaging, however it could be improved even further that is how efficient they can be, however a great result):

They can also be purchased off-the-shelf.

"DHW Only" Heat banks knock cobs off unvented cylinders.
Look at:

An integrated heat bank (DHW & CH), as Gordonspants fitted, is different and cannot be directly compared to an unvented cylinder it is so much more advanced.

utter cobblers.

it was a thinly veiled exercise in you talking to yourself from 2 different ip adresses, come on who do you think your kidding?
