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

True the temperature in the cylinder may have to be a bit higher than may be comfortable for the wash basin hot tap but with a thermostatic mixer shower it works very well.

Hard-on & Berny have reinvented the Sludge Bucket!! It's amazing their depth of knowledge(BS).

He's not right, it's drivel!!

Don't they have combination cylinders in Glasgow?

 

[hard-work]

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

Shouted down? Typical. Yes the dead leg maybe too long. Then you need separate water heaters, for opposite ends of the house. I would have thought all the pipework would run through the loft in a bunglow. I would re-pipe it that way.

Good lateral thinking HW; no ones come up with that yet. PM Shakey and see what he thinks.

The problems with many of these on the market a number of years ago, was that the shower coil was always too small with the cylinder water temperature needing to be too high. They only ever did one shower at a time. They needed larger coils and especially when two showers are needed, then you getting into full thermal store territory.

You were better off with a combi serving only the shower and a combination cylinder doing the rest. A nice cheap way of doing it. The combi will last and be reliable enough as the water section is only being used a few times a day.

So you are claiming that a cylinder fed at the bottom with cold water from a cistern in the loft and supplying low pressure hot water from a connection at the top of the cylinder to taps in bath and wash basins is a sludge bucket. ?

Dickie is referring to a thermal store.
A hot water cylinder fed via CWSC wouldn't utilise a mains fed coil..

ye thats really cheap isn't it

Mine was custom built so I specified the size of the shower coil. But made it too big which reduced the volume of water in the cylinder. But it works and does two long showers with ease before the temperature in the cylinder drops too far.

It does have a mains fed coil for the mains pressure hot feed to the shower. It is part thermal store ( to heat the mains pressure coil ) and part hot water cylinder fed via CWSC

What does?..what unit are you referring too.
So the stored water temperature within 'cylinder' is around 80c in order to heat mains coil?..and you're also saying another tapping is used to feed hot water draw offs?
Enlighten me.

You having a laugh??
Who manufactures these units?.
80c stored water temp feeding hot water outlets?

 

[Steelmasons]

Hey Bernard , this must be one fook off sized unit in order to enable surface area of HW mains fed coil along with volume of water for gravity fed HW outlets.
Unless you're referring to what's known as a 'sidewinder' which was an add on and not supplied/recommended by any cylinder manufacturer.
These were also absoloute pants when fitted due to surface area of coil , also the cylinder was susceptible to scale due to high store temps.
