Hi

I would like to hook up my solid fuel stove to the existing ch system.

The problem is that stove is a long way from the boiler so connecting them via a hydraulic separator before hooking up to the heating circuit is difficult and would also require a lot of work to keep the pipes hidden.

A gravity system is only really possible by adding a tank in a cupboard behind and to the left of the stove but even if a tank is put in this cupboard connecting it to the existing ch system is still the issue.

In that cupboard there is access to the ch circuit at the point where the flow becomes the return (28mm pipes). Running new pipes from this cupboard is difficult, so what I am wondering is if there is any way around this. There is also a 3/4 pipe here that is currently unused.

If anyone has any ideas I would love to hear them. I don't have a lot of money to do this, so I am looking for a simple and inexpensive solution that will work.

I have some pipe, fittings, a spare fixed speed pump, a old hot water cylinder (80 litre), and a motorised valve.

Safety is always a priority.

Only answer is get a HETAS engineer to design and install , cold water at normal atmospheric pressure exands 242x it’s original volume when converted steam

Oops sorry blame the bbc program about steam engines,
Rob Foster....1600:x it is even more reason to not muck about with this type of installation

Yep definitely, people really don't realise how dangerous it is, because as well as the explosion, you get scalding water acting like shrapnel and metal shrapnel.

Some of the videos on youtube of cylinders blowing up are truly eye opening!
 
It must increase the mass of the water as you are adding mass to it in the way of salts, so yes, increasing salinity must increase the weight.

Yep that would make sense, wish chemistry/physic/bio a-levels weren't such a distant memory!
 
Ok, thanks for the safety advice.

I live in Ireland we don't have HETAS or any other body for solid fuel (gas yes, solid fuel no).

I have had 2 plumbers around and the only safety consideration they had was to use a pressure relief valve and they had little or no knowledge about hydraulic separation or neutralisers, etc. but they were both willing to do the work.

Any work I do myself will be okayed by a plumber before being commissioned.

So what I am trying to do is figure out if there is any way to connect to the ch via the flow and return in the cupboard or do I need to connect to a point between the boiler and the first rad via a neutraliser etc. and create a primary and secondary circuit.

I presume there is no way to do the former but maybe someone has some possibility, complicated though it may be.

Hi Paul
I did the same thing many years ago in an old farmhouse. The plumber made a total cockup to start with, resulting in the plastic expansion tank in the loft melting from the excessive super heated water from the back boiler and flooding our daughters bedroom . His solution was to replace the plastic expansion tank with a galvanised one! I did some research and contacted Dunsley Heating in Holmfirth, West Yorkshire. They recommended their round “Equalizer”. I got another plumber to fit it and it worked perfectly for many years. The only mod I had to do was fit a magnetic thermostat to the equaliser which started the circulation pump when the temperature reached a certain level. I think it was set to about 8O deg c. This was only necessary when the CH was not on but the solid fuel stove was in use.
Hope this helps.
