Stove

I am thinking of replacing my open fire with a wood burning stove.

Couple of questions if anyone can help please

1) I currently have a wooden fireplace, do I need to replace this with a marble one (i was told the wood fireplace may crack with the heat of the stove)

2)Any ideas on price difference between stove with and without back boiler

3) Do i need to get my fireplace knocked through to allow a stove insert

4)Which stove give out best heat, an insert stove or standalone stove

Any help here very much appreciated

An insert stove won't give the same heat as a stand alone one. If you can heat rads with a back boiler stove it it's a no brainer to get that option if you're going to be lighting the stove fairly often. The price difference will be in hundreds and well worth it in the long run.

You won't believe how little fuel you will go through in a stove compared to an open fire, they are very efficient and once you get used to using one after a few weeks there should be no fear of cracking a thick wooden mantle or uprights.

If I was buying a stove I'd go for the multi fuel option rather than just a wood burning one, there is good value in using ovoids or coal and they are easy to source.

Thanks a mill @Rows Grower

I though having the back boiler would cost a fortune buts if its a few hundred well worth it

Very helpful. Any suggestions on brands of stove to go for?

I’d be ignoring this reply if I was you.

A 5kw inset stove and a 5kw freestanding stove will strangely both give out 5kw. So once you know what kw you need then use the same logic.

Every stove is tested for a distance to combustibles. This will tell you if it can be used with your existing timber fireplace or not. There is no broad rule covering all stoves.

Boiler stoves have shot up in price. Expect to pay upwards of €1500/2000 for most boiler stoves now. Plus increased install costs for plumber etc. A room heater stove will be half that. On average a boiler install going to cost 3500-4500. A room heater €1500-€2000.

We went with a Heritage Derg about 12 years ago and have no complaints with it.

At the time they were being sold through Right Price Tiles but they don't seem to be doing them anymore.

This crowd in the north came up when I googled it, they are a fine stove.

Here's one: https://www.charnwood.com/stove-calculator/

Lots of the manufacturers do similar.

how does the back boiler part work?

For a boiler stove a plumber should calculate it accurately. As an estimate you count how many radiators you have(a single radiator is 1 but a double radiator is 2) and add 3kw to the total for hot water tank. This will tell you how much you need for the boiler. Some boiler stoves will then say they have a room heat from 4-6kw but generally they don’t give great heat to the room as their primary function is to heat water.

For a room heater use one of the calaculators mentioned above.

Also the Heritage Derg mentioned is discontinued with 6 years.

Boiler stoves are hard to get now due to new EU emissions regulations. Stratford and Charnwood would be considered the best but you will pay through the nose for them. Stanley way overpriced for what they are. Some good models if you can get them and they suit your requirements would be the Olymberyl Aidan, Henley Druid, Boru Carrig Mor and Henley Achill boilers.

If you are going for a room heater there is massive option there.

If you already have OFCH or similar fit a stove without a back boiler. Fitting one with a boiler could be costly depending of the layout of copper cylinder, pipework etc. Also in case of power cut or mains water issues which normally happens in severe, stormy, freezing weather, you'll have heat in one room and depending on the stove you fit you may be able to cook a meal or boil a kettle.

Thanks for all the advice

I’m being quoted €2300 in Dublin for a 5kw insert with install & sealing the chimney to improve the BER. Not a boiler stove. Seems to be an Atlantic stove. Any reason I shouldn’t be expecting the €1500-2000 range these days?

Dublin would be normally more expensive than any other areas. Does that price include a flexible chimney liner? If yes is your house single storey or two storey and is it accessible by ladder?

High grade flexi flue was what it was described as and it’s a two story semi detached.

Have seen the stove itself retailing for ~€800. As you said, Dublin prices. Have got one other quote today which was in the same ballpark so might have the answer.

A high grade liner is a 904 grade liner. A standard 316 grade liner would be the norm in most installs and could be €200/300 cheaper. I would only advise 904 for heavy daily usage of a stove. €2300 is a fair price if 904 grade is being used.

Just on the 5kW being 5kW thing, how much of the 5kW goes to the room? I would always have been taught that the inset stove would see more heat go up the chimney than the free standing stove.

That is a question of efficiency. I would imagine that an inset stove would be a little less efficient than a standalone, as there is less surface area in which to allow for heat exchange with the room.

But in theory this efficiency figure will be built into the design. Two 5KW output stoves should each give the same output. If one has a lower efficiency, it may take a little more fuel to give you the 5KW output.

Personally I would take those KW figures with a pinch of salt. The real life situation will vary greatly depending on fuel used and flue conditions. They are at best a rough guide.

Spot on. I would always advise trying to find the test certificate for the stove as it will show KW, Efficiency and fuel types used.They were easily available online but not as much anymore.
