Thinking about installing a stove and boiler

deeksofdoom

I'm thinking of having a solid fuel stove and back boiler installed in my house.

I currently have 2 open fires in the house one of which I don't use. we have oil central heating, its 3 zone heating - upstains , downstairs and water.

I'm just trying to understand what my requirements are at the moment before I get a few quotes from plumbers etc...

The house is approximately 1600 sqare foot, we have 15 rads they are all 'Double panel with fins', I was doing a bit of googling this morning and have calculated my heating requirements for all these rads to be approximately 19Kw thats not including heating the water in the tank (I'm assuming I only have a single coil tank, haven't looked at it yet)

The room I intend to put the stove in is a good size room 4.2m X 5.8m X 2.5m by my googling calculations it requires 2.5 to 3KW to heat. Now the room is on the gable of the house and it has 3 windows and a large door leading out to a patio, so I'm guessing that all that double glazing will increase my heat loss. However some of the boilers I have been looking at have an output to the room of 5.5kw to 8Kw - would the heat be unbearable in the room with that size of output, if i was to reduce the fire in the stove wouldn't it have a knock on effect on the heating output to the rads.

Should i go for a more Kw output rather than less?

how much kw would it take to heata tank of water?

What kind of questions should i be asking the heating engineers when I get them in?

To be honest' and I'm not trying to sound like an ass here...you'll struggle to find a stove that will heat 15 double rads to a comfertable temp....
And if you do your gonna be horsing fuel into it all day long.

You will be looking at a boru 30kw which is the biggest and most popular stove of this size
Do some more research on the cost of running a stove of this size as it is more expensive than the oil to run and you will need a conveyor belt to keep it fueled
A stove seller or plumber/installer will not warn you of this as they just want the job/sale
A good dry/room heater stove will heat the room you use, and is easier to keep in fuel.

I fit stoves and call to many people to try deal with problems regarding boiler stoves ie no heat from stove to room, using massive amounts of fuel, smoke spilling out of door and chimneys blocked after a few months use.
I have never met anyone who is really happy with a large boiler stove!

Keep researching and check (fuel cost comparisons) also factor in approx 3-4k to buy the stove and have it fitted

I was thinking about something along the lines of a Waterford Stanley Reginald, I know its not a boru.

Its 5.5 kw to the room and 14Kw boiler output.

I don't have to heat all the rads just some of them. What would you think.

All i want is to try and harness some of the heat thats going out the chimeny to heat the rads and the water.

the output figures given will be the maximum so if you are close to the limit the next size up would be a good idea

You can always light a smaller fire in a bigger stove, but you cant burn more in a smaller stove to give more heat than it is rated for.

the closer to the limit you fire a stove the more heat it will put into the room.

around 2kw

Agree with both of the above.
20-30kw of heat is a lot of fuel through a stove.

I have a 30kw Boru carraig more boiler stove In the corner of a 4.5m x 10m x2.4m room, It you run it hard it quite easily pushes the room temp up over 25oC

Important point most people underestimate the costs of stoves and installations.

the 30kw Boru lists around €1800 from memory add to that the flue, pipe and fittings, new cylinder if needed and your material cost gets quite high. and if you have to start pulling up floors, chasing walls etc there can be alot more labour involved than you might think.

As stove man said allow 3-4k but if could be more if its a complicated install.


ask plumbers/installers about thermosyphon, if and where would they would use an injector tee, will they be using 1" or 3/4" qualpex;) , where will the pipe stat be fitted, what stoves they have fitted, would recommend, and what they didnt like about them.

The stanley reginald is a well built good quality stove so no problem if it is not going to heat all the rads.

A boiler stove uses approx 3 times as much fuel as a non boiler stove, it is this extra fuel that is used to heat the water.

A common mis-conception is that you may as well heat a few rads if you are going to run a stove anyway, you will only get out the heat from the fuel you put in, ie 30 kw stove will use 5 times the fuel of a 6kw stove

Get a quote from a few plumbers and work out the cost of fuel and make a decision based on all the info
