Cylinder Mods

[BoyWonder]

I have an old house with similarly antiquated plumbing modified over 80 years. To resolve a major air lock I have had to separate the boiler (central heating and secondary hot water cylinder circuit) from a Rayburn stove (also feeding the same jumble of pipework) and fit motorised valves. The boiler and associated circuits now work faultlessly but we also want the Rayburn as a hot water source (since this will be effectively free heat). Clearly we cannot go back in to the secondary circuit but I understand I can connect directly into the body of the cylinder.
In this regard can I connect via Tees to top and feed pipes? If not (and I suspect that the flow to taps would be inconsistent by this means) how and where do I drill into the cylinder and what precautions (apart from the obvious one of emptying it!) do I take? What connectors will be suitable given that, unlike a tank, it is a curved vessel?
The alternative would appear to be another secondary (tertiary??) coil. Do cylinders like this exist or can a coil be retrofitted?

My grandfather used to have a directly heated cylinder from a coke boiler!

Nowadays you would not do that so would need a further coil or a plate heat exchanger.

You dont say what fuel the Rayburn is burning but assuming its uncontrolled solid fuel then special precautions and a heat leak is likely to be needed.

Thanks for both these. The neutraliser looks like a solution - till I saw the price which is comparable to a new cylinder. I shall look more closely at the Systemzone approach for which I could see no prices.
Tony, it is an oil fuelled device so has some control over heat output via the control valve but would not regulate the hot water output. Having seen the results of this from a faulty gas boiler I do take the point.

I'll have a ponder over the summer - luckily I don't need to rush this since the boiler is happily covering all needs.

A systemlink manifold is about £150.
