fireboard for stove surround

fiestaman

Hi i am putting in a stove into an open fireplace, opening will be 36"x36". could i use sand and cement plaster in the opening or would i hav to use fireboard??

sand and cement will be fine for what you need, what KW/h is the unit you have?

fiestaman

stanley erin. 13.2 kw

Sand and cement be the finest lad. Ya going to have rads off it?

fiestaman

ya rads on zone 2 which is the bedrooms and me toilet.

Good stuff. SHould be well capable of heating a zone and cylinder.

I will be putting in a sechondhand stanley super star solid fuel range. I want to run some radiators of it, not much room near the range so I wonder if it would be ok to fit the circulating pump upstairs near the hot water cylinder

You will probably be fitting the pump upstairs anyway near the injector tee. You will have to run heat resistant cable however to the stat on flow from range.

Thanks. Will I have to fit the stat near the range ?

It usually states in the stove spec that within a half metre of the stove flow pipe exit from stove. The system should have a gravity feed anyway for safety with no restrictions on pipework such as pumps on the primary circuit.

Thanks Kay 9
I got a guy to look at what I propose to do. He advised me to put the circulating near the range or otherwise I would encounter problems. He gave me a list of materials I will need it included two injector tees. I know I put one on the return pipe from radiators but I cant fathom out where the other one goes. Any help would be greatly appreciated

I don't know why he requires 2 injector tees to be honest. If he puts the pump at the stove it will restrict the gravity loop. Rule of thumb is have the pump pumping back into the return from the heating with injector tee the stove side. Just make sure that he has a constant gravity (safety loop) in the event of a power shortage. Is he taking 2 returns and 2 flows from the stove? Curious why he wants 2 injectors hmm

As I understand it, its 2 inch pipes from the range to cylinder ....gravity flow. Off these two pipes near the range we will take 2 3/4" pipes for the heating circuit with the injector tee fitted between the range and the pump on the return pipe. perhaps he ordered second injector tee by mistake. I think I have a basic understandind of how the system works now hopefully

2 1" pipes is correct anyway. Just make sure you have a loop and insulate all well especially in attic for fear of frost. Is the flow going up the wall and the return down?

red bull

Not sure I know what you mean by loop, is it to have an unrestricted gravity flow or is it pipes for the radiators flow and return ? yes the flow is going up the and return down why ?

kay 9

It's very important that you have a constant circuit(Loop) meaning an unrestricted exit for flow from stove back to the return. Usually this constant circuit is to the primary circuit which is the hot water cylinder. Hence the reson for not installing pump at stove. I'm not the best at explaining mate, but hope that helps:) The flow from stove must if at all possible go up after exiting stove as to minimize the risk of banging or even an explosion(although quite rare, it has happened) Return can go up also but usually goes down.

Thats fine, Im taking the heating circuit 3/4" teed off the primary circuit 1"
Should be ok.

Ah it will be ok red bull, you will need to have smaller fires for the first week or so and gradually increase it.
