I bought a house with two stoves in it. After a few winters I'm considering ditching both of them and replacing with something more suitable.
The previous owner of the house obviously spent a few quid extending and renovating etc but I think he didn't think through the stove selection properly.
The kitchen/living and dining rooms are open plan and have an overall floor area of 64 sq. M. Doing the sums, this requires 9.4kW to heat and with a 75% efficient stove, would require approximately 13kW of stove output. There is a Stanley Erin in situ in the dining room with back boiler and TBH, it does a piss poor job of heating the space and the 8 radiators. It does neither job well. So the plan is to replace it with a non-boiler stove and just let the outdoor oil boiler deal with the central heating. All going well, we could even turn off the three radiators or at least turn them right down in the three rooms exposed to the heat of the stove.
The other stove is in the living room is a Stanley Tara oil burning stove and it's an expensive ornament at the moment. In the years we've been here we used it twice and it stank up the house so we've avoided it since.
The way I'm thinking at the moment is to swap the boiler stove for a properly specified non-boiler model, probably multi-fuel (maybe wood-only?) and swap the oil stove for a lesser specified wood-burning stove for occasional use only. Last winter we burned wood exclusively, the winter before, both wood and coal. We have taken delivery of another load of timber so I'm planning on wood-only from here on out.
So, what I'm really asking is: what/where's the best value in stoves at the moment? I'm hoping I can sell off the two existing stoves on donedeal to fund their replacements, they're both enamel finish models so should make a reasonable price. It wouldn't bother me to buy matt-finish stoves as replacements. I have a quote of €1575 for an enamel Stanley Erin non-boiler which I think is excessive. I'd be hoping to replace both stoves for that. I'm not brand-snobby BTW
any help/pointers/advice appreciated

Hi, I calculate you need a max of 10kw to heat the open plan space based on 8mx8m, with 2.4m heigh ceilings.
I would say it's a case of shopping around for the best price/deals whether here or the UK. On google uk type multifuel stoves:) We ordered our villager stove from the UK as it was cheaper.
Are you absolutely sure you want to ditch your boiler stove because surely with the cost of oil it would pay, if you could get it working better or a replacement? It has a 45,000btu boiler so should do better. A person who did work on our house has a stanley erin but it didn't work great probably due to the rubbish install and plumbing install. Trapped air due to pipework running down from stove, undersized pipework, not crossflowed, excessive horizontal flue, no heat leak rad, no seperate feed and vent. vented using oil vent. Pipe stat on pipe miles away that never got hot so stove just boiled. In other words a right hash job.
I wouldn't be without our boiler stove:DIn fact it's our only form of heating. Maybe the stove is running all doubles or large rads and so undersized?
Granted it should half heat the space:(
ours stove produces 3kw to the room of 28sqm and heated it well even in that cold winter, but it's a well insulated detatched bungalow.
I myself would evaluate the boiler stove and installation before condeming it. See if it's plumbed in correctly, install a small multifuel stove in the living room.
If you would measure the rads and note if doubles or singles I'll see if the stove is undersized if you want me too:).

radiators:
1.6M x 0.5M double
1.0M x 0.5M double
2.0M x 0.5M double
1.2M x 0.3M double

1.2M x 0.5M single

the house is basically divided in two, the older section, built 1975ish and contains the bedrooms and bathroom. The newer section, built 2005ish has the open plan kitchen, dining, living rooms plus a small utility. Even with no heating on, the new section is way warmer than the old section.
My thinking is that we use solid fuel to heat the new section, turn off/down the radiators in the new section, close the door between the new and old parts of the house and just let the oil heat the bedrooms. The old section has already had the walls pumped with styrofoam beads and I stripped out the old 100m fibreglass loft insulation last year and refitted 300mm glasswool instead. All windows are double glazed. So the old section is as well insulated as possible without cladding the outside.
I just didn't feel like we were getting any result from the radiators on the stove alone. When the oil boiler kicked in, it warmed the radiators up better than just the stove but after the oil kicked out again, the stove didn't really maintain the heat in the radiators. Plus there was an overflowing issue with the c/h header tank, with both oil burning and the stove well fired up, it would overflow warm water out the eave pipe occasionally. Had a plumber look at it and after replacing a seized water pump on the boiler he thought he had it sorted until it happened again. Since the weather warmed up a bit I haven't gone after the problem. I'm hoping that ditching the back boiler stove in favour of a non-boiler model will solve a few problems.
**EDIT** just re-read this bit:A person who did work on our house has a stanley erin but it didn't work great probably due to the rubbish install and plumbing install.

not much of that makes much sense to me except I know the pipe-stat on the system is a good bit away from the stove. Does that make a big difference?0 -

Hi, I have calculated you need a 18kw back boiler stove to heat everything including hot water, although it would need to be a bit more powerfull if not using coal or the wood fire wasn't roaring for a good hour. I find a lively fire is essential for the first hour.
Your stove isn't far off so I'm highly suspicious of this problem with overflowing and should certainly get 6 rads hot after about 60-90 minutes with a good fire going.
You shouldn't run the stove and oil boiler together unless specially linked using a systemlink or centraliser. Otherwise you may well get pumping over/pitching problems and possible water running out the overflow pipe.
See if the water is warm in the smaller tank in loft etc when the fire is lit without the oil boiler on and see if any water comes out the vent pipe. It is probably poor pump positioning on the solid fuel fire or using both boilers together. This is probably where your heat is going by heating up the water in the cold feed and expansion tank. Do you always use both boilers together? Try the fire without the oil being on.
If your system isn't linked using a system link you should have 2 central heating pumps, one near the oil boiler or inside the boiler case and one near the boiler stove. Running both pumps will cause issues as they are conflicting with each other.
The pipe stat needs to be on the flow pipe that actually gets hot. Normally near the stove on the flow pipework or on the gravity flow pipework to the hot water cylinder. This is the pipework linking the stove to the hot water cylinder and should always be in 1 inch diameter pipe which doesn't require a pump to circulate the hot water through it.
After 15 minutes of the fire lit go and feel the pipe that the pipe thermostat is attatched too. If it's getting warm/hot it seems correctly positioned. If not follow the hot pipe from stove along, this is where the pipe stat needs moving too.

It feels weird lighting a fire in the middle of June :eek:
I didn't get around to it last night but the stove is stocked up and a good wood fire burning since about 4.30 this afternoon. As I type, the radiators are only barely warm (like just gone off cold) in the top inch only. The rest of the radiators are basically cold.
We also drew a bath for the little one, no hot water from the stove, again, just barely off cold. Resorted to boiling kettles to heat up the bath...
There has been no over flow out the eave outlet as of yet. The oil boiler is fully off and won't kick in on the timer at all so the stove is responsible for any heat/water/overflowing issues, should there be any 0 -

Hello all,
I am going to replace my 16" open fire with a non boiler inset stove my room requires approx 5kw to heat it, I have narrowed my choice down to 2 makes the clearview vision inset 5kw or woodwarm 4k or 6.5kw I would be grateful for any advice on these inset stoves.
Also I intend to install a 6" 316 flexi liner into a 8" clay liner the house is 2 story and the chimney is straight and 9mts high and in the middle of the house, Q would there enough room between flexi liner and clay liner to insulate. or would it be ok to leave it uninsulated.
Regards
couldnt recommend it enough. we put in an inset stove last year and its athe Boru inset, small heart in irish i think. some serious heat out of it, cannot sit in the room without the door open! u would pass out... great heat for such a small stove, very efficient also.
now, i am kinda sorry o didnt perhaps go for a boiler stove and had piped the yoke up to the heating too. but it would ave been a good weeks work or so. but then, thats all it is, oh and an extra grand or 2 probably. 0 -

Hi, could you post up some pictures of your stoves plumbing:) Was the water warm in the small feed/expansion tank? What is your pump speed set too for the stove? 2or3?
Where is your pipe stat located and did the pipe heat up and the stat switch on the pump? What is the pipe stat temp set at?
The photos may well help.
The heat must be going somewhere. Is the wood well dry and well loaded and roaring for a good hour? Is the thermostat on full on the rear of the stove? Does the chimney draw well?
