As a general note. Using a combi boiler for a high pressure show only and using it to heat a low pressure combination cylinder with a 3/4" ballcock and 22mm cold water mains supply for the rest of the hot water is an excellent way. The 3/4" ballcock will ensure the integral hot water tank will be filled quickly. It is cheap, safe and reliable.

Good luck with fitting a 3/4" ballcock and a 6" ball in a 18" diameter combination cylinder.

I can see it now......ole Hard-On muttering "oh fook..."....
If anything he should of suggested two 1/2" ball valves although he spouts total bo!!ocks whenever he touches the keyboard.
Kind of defeats the object suggesting a 3/4" ball valve , by the time the ball valve arm is bent in order for the 6" float to clear the lid the water level will be just proud of cold feed outlet......****...

It's filling from the cold storage tank on top of the hot water cylinder, so it's going to be low pressure, not mains pressure for the hot water take off. But Shakey wanted the shower to work off of the new water heater (whatever that would be) not the old combi, so this would really need fitting in the loft to give a god head of water pressure, even for the kitchen taps, certainly no good in a bungalow.

Am I seeing something others are not or is it Specsaver time for me
The big picture is of a cylinder where the cistern is, I presume, maintaining the primary system at low pressure so not suitable for a sealed system boiler, e.g. a combi, unless it is an Intergas. Does anyone see the blending valve? Thermal store comes to mind. So hot water will be at mains pressure. While for hot water, cylinder siting is of no importance but to have the primary system carry out the task, cylinder needs placing at a higher point

Second picture is a combi cylinder which. Here the hot water will be at low pressure or am I wrong?

They are available.

Big picture is a thermal store. it can be heated by a sealed system gas boiler, open vented boiler, solid fuel, solar ect ect , store can be sited any where.

and thus less work for G3 plumbers.

Run mains pressure water through a second coil in the top of the low pressures cylinder for the shower. Avoids the need for a combi and the complications / compromises that come with a combi.

An alternative to a coil inside the cylinder ( which reduces water volume ) is a coil(s) wound around the outside of the cylinder ( inside the insulation ) and thermally bonded to the copper of the cylinder.

Bernard, shower coils tend to need very high storage temperatures with a blending valve for the DHW taps to drop the temperature.

No, DP, it was my vision express moment (just breaking in new varifocals) I thought it was a hot water cylinder with cistern above it, so my mistake.

But I think I'm going to nominate this thread/situation for the most confusing I've ever come across; if only because we're discussing a poster that isn't even posting on this thread. Shakeys original thread got shut down because people started arguing, and here we again.

The combination cylinders look like that. One neat unit. It is technology the average plumber can understand.

Combination cylinders are easy to understand. A simple one unit solution.

No you cannot. You do not even know about gas relay valves. Unless you are converted on the road to Damascus you will never see it. Sad......but true.

 

[Doggit]

You're right Hard-work, but it wasn't the solution that Shakey was after; he wanted a seperate water heater of some sort because of the distance of the kitchen/bathroom from the boiler, and the hot water not getting through because the pipes were bedded in concrete. Most disagreed with him, and the only person that tried to give him the solution he wanted, got shouted down

Clueless drivel!!
