heat pump without stove

gooner99

From reading passive house plus and some threads here some have installed stoves as secondary heat sources but never use them as their heat pump heats their low energy or passive house quite cheaply. So the stove really becomes a focal point, albeit a very nice focal point and maybe lit a Christmas. I was thinking in such a build that a fake fireplace or similar with grate and logs or candles or the like would create a nice focal point. Anyone do this and would this result in much of a saving on the cost of installing a chimney, suitable external air supply stove + fitting. I know you could spend a fortune on a stove or go with a cheaper model, but how much potentially could be saved by removing a chimney and stove setup?

Noisy heat pumps don't work without electricity..

But maybe you can scrounge a few bits of timber To keep the house warm

In last year more of these are out...in the flesh really cool/realistic ...

You could save on the cost of a stove and chimney by buying a backup generator powerful enough to run the heatpump....

My guess is that you'd probably get away with something around 12-15kw....

*I have an A2W system....a couple of years ago the power went off for about 3 days. I was never as glad that I had a chimney and a stove at the bottom of it....a completely lifesaver...I have a backup genny that runs the lights and water pump (i have a well) and either the kettle or the microwave and a few other bits and pieces but its not big enough to run the heatpump..

Also balanced flue gas fires.. be it stoves or built in wall units..can go straight out wall...no need for built chimney, so can be very cost effective and can work with passive house / sealed room with no vent in room..
Very controllable heat and flame.
No ash.

Your not a fan of heat pumps Bryan. I'd imagine the majority of the folk affected had oil or gas burners that wouldn't work in a power cut either.

Those look real nice. They are not fuel based, just a flame effect right.

Are there stockists of these type fires in Ireland?

Sounds good. Do you have experience of these?

Any links to examples?

No problem with them at all, once they reducing the use of fossil fuels. in Ireland we should be looking at where our electricity comes from

Maybe ask the question on the need for a fire? Put the costs difference into something else.

Didnt put one in and its the best decision ever. One less job to do around the house. Plus one less headache to source and store fuel.

Now build starting,
Spent more time thinking about this than I care to think of.

But went from stove to gas to electric to pellet back to stove, end of day the stove won over ascetics ease of use and the smell of burning wood logs on a Christmas morning.

Doing an insert stove with external feed.
But put in a valve for external feed in order to not have a reverse radiatior, Eg cold air flowing through the stove when its not lit and cooling the room. Dont have this valve electric as in a power cut you wont be able to open it.

I met with an interior designer. Wasn't thinking of a stove in my self build due to cost of flue etc but she pointed out it would be a nice focal point for the corner of the living room. I like the free standing circular stove type. I'm planning on going with a Bio-ethanol version. A litre of fuel lasts 4 hours and it has a nice flame effect. No pollution, it's about the same as having 5 lit candles in the room. Not using it for heat, just for visitors. ASHP will take care of heat but no backup with this approach.....

Yes all available in stove/ heating outlets.
Dru gas fires are really nice
Gazco have nice range as well

Heating wise we did not need a stove (ASHP has us covered), but we went ahead with a small standalone 7kw one. Pretty happy we have it, its small and in the corner and great to sit around in the winter nights. Have it on 2/3 times a week. have an old metal drum of a vaccum that makes short work of the ashes.
If our budget survives, may do a 2nd stove (inset) in sitting room in a year or 2.
I have the summer to source logs and an excuse to get a chainsaw.
