Stove query & back boiler

If you already have a copper cylinder with a coil you should consider fitting a suitably sized stove with back boiler- the back boiler to be used to heat domestic hot water only as a direct cylinder system. Your oil boiler will, with the use of motorised valves etc., heat cylinder thru coil in summer or when stove is not in use.
Also, assuming that house is occupied during the day to do the stoking, you can use the stove for cooking etc. and save on gas/elect.

stove all the way had an open fire with back boiler and found it useless,changed it to a stove[with a back boiler] and have never looked back

It can be done, have you easy access to pipes at back of stove ? Get your plumber to sort pipework out. Replace boiler with fire brick, should be available off the shelf.

Where would the damper be located and what does it look like? Could this be the temperature dial you mean?

No its built into the stove, you need to look up the manual of the stove and it will tell you the location. That picture shows a thermostat that probably triggers the pump to come on

so you still have the boiler stove, just its not connected to the boiler anymore?

I have an oil burner as well but when I turn that on, the hot water flows into the back boiler. Should that be the case? To me it should just circulate around the rads to be most efficient. Also how big are back boilers usually?

Would that improve the heat going to the rads as right now some are only warm , especially downstairs when the oil heating is on.

It could but the thing is you don't need the big roaring fire on anymore a few sods would keep it going,also seems to be running a lot cleaner glass not getting as black as it used to can't belive people are still connecting stoves to heating systems as with the price of coal at the minute and turf won't heat rads might in a small house with 3 or 4 rads.

A swing type non return valve correctly fitted on the stove isn’t going to cause any real issue. The stove remains fully open vented and there is no safety impact.

What you describe is undoubtedly preferable, but this is an existing installation and would involve significant modifications to pipe work.

If it was me, I’d live with the boiler circulating through the stove. I don’t see it causing any great issue. When you choose to introduce solid fuel boilers to heating systems you have to accept that your ability to control the system will be significantly reduced.

Yeah, as I am finding this to be the case now, some rads warmer than others, I am thinking of just getting rid of boiler and then its a case of is the boiler stove usable as a dry stove or do I need to go out and buy a new stove?

The rads warmer than others can likely be solved with some balancing, and possibly a flush of the system if there is significant sludge buildup.

If it was me I would get rid of the boiler stove. Put in a room heater only model. You could then add some time and temperature controls to your oil system.

Out of interest what health and safety regulations would they be?

You might be as well get your own one disconnected, ASAP!

A pressure relief valve. It opens if the pressure in a system exceeds a preset level and releases pressure/hot water to a safe place (ideally outside).

Should be fitted to any boiler (incl oil) as a safety measure. If something went seriously wrong, any excess pressure is released long before there would be an explosion risk.

I know exactly where you were heading with your Questions, and your attitude to fitting a Non-Return valve on the Primary pipes of a Solid Fuel Boiler, etc.

Also you asked the following question:-

“Out of interest what health and safety regulations would they be?”

The answer is - The Building Regulations, whose main 3 purposes are for the Health Welfare and Safety of Persons.

Here are some of the Regulations for Health Welfare and Safety of people when fitting Solid Fuel Boilers below:-

No doubt you will obtain copies of the all the BS EN specified to read and check.

For people who cannot understand written Regulations, the Solid Fuel Boiler Manufactures also provide Diagrams-

I will not be taking your last advice above to Disconnect my Solid Fuel Boiler, as you know absolutely zilch about my boiler.

Note: When solid fuel boilers are to be made redundant, they MUST be completely Disconnected and Must be removed. There have been many Explosions of disconnect solid fuel boilers left in place by Delboy Trotter &Co.

Mine is installing 100 % correctly. I did not allow any incompetent Plonkers or Morans near it.

The Non-Return Valve is fitted on the Oil Boiler Central Heating pipe next to the Circulating Pump on the Diagram as per the BS EN. This prevents hot water from the Central Heating Oil Boiler from entering the Solid Fuel Boiler.

Absolutely nothing fitted on the 25 mm primary pipes, and no valves fitted on the Gravity Rad as per diagram above.

It is so amazing that everything in Construction is so simple when done correctly to Regulations and Standards etc.

Will I be charged for simpling assessing the system as that will need to be done before he does anything.
