I can't believe your house in 20 degrees! I live in a 1900 typical terraced valley miners house and it's around 10 degrees... Must be the oak door you fitted, must be monstrously tight fit hahaha Could you do a video to see if upstairs is warmer too? Your videos are epic. Love the little squabbles with the other half. Keep up the great work and looking forward to see more videos!
I do plan a number of other tests when I got a larger stove. Currently I’m testing an enamel, which to be honest doesn’t lend itself to hugely functional use 😆.
Fantastic real world test and that's a big open space. Looking forward to the test with a bigger stove and maybe a second pump? Door looks great as well!
I am VERY VERY close to placing an order (and will use your link). Just wondering if a chimney sweep would do the install or would I have to get the fireplace installers back out?
The requirement is for a competent person. I would expect a lot of end users are competent, and certainly most chimney sweeps. From what I’ve been told there is no requirement for any kind of HETAS certification for this to be installed. It may be useful to get the fitter depending on your flue set up, but if you have an adjustable pipe like me then basically anyone could do it. I believe the instructions recommend testing the draw after too, to ensure it hasn’t caused the draw to be below the stoves requirements, but the chances of this are almost zero. Draw changes constantly so it’s impossible to prove, but I didn’t sense any change in draw on my chimney at all, all the readings were essentially the same.
Hi Gabriel when looking at temperatures inside the house the external temp must be taken into consideration too and wind as well. I have a meter on my oil and when it’s day 12 degrees we use day 8 litres of oil but when it’s zero degrees we use 14 litres of oil. Good work on the door by the way
You’re correct. I remember checking the weather trying to find 2 similar days. According to the weather apps the 2 days were basically the same, the reality could well have been different but there wouldn’t have been much in it.
Hi Gabriel, fascinating stuff. I wanted to place on record my thanks to you for your advice on PM2.5 particles the other day. I had actually (before contacting you) ordered a Temptop particle sensor, which has now arrived. I wanted to make it known to your subscribers that the (from my sofa in front of the Heta 45) results from the particle meter bear out absolutely the advice you gave me that the stoves are not gushing out shedloads of pollutants (well, my Heta 45 isn’t) and your advice seems absolutely correct based on my armchair study. Many thanks to you....🍷🍷
We bought the Temtop M2000C from Amazon, at £150. I think we could have saved about £20 by looking elsewhere but Amazon delivered next day. Simple to use and, it seems, fairly well rated for accuracy.
Hi Gabriel, great channel and test. I'd like to get one of these, but my 5 inch flue is cemented into the collar. Any ideas on the best way to remove the cement without causing damage so that I can raise the flue enough to get the recoheat in. Thanks.
It will come out with relative ease, but at first look will appear very solid. If the stove is pulled forward and tipped back that cement will crack and come out relatively easily. But it’s always possible to call your fitter or sweep if there is anything you’re worried about.
Great test! Thanks for taking the time to set it all up and run it with and without. I'm so pleased that someone else is this obsessed with finding out how well things like this actually work. Keep up the amazing work on your channel and I hope it continues to grow for you. Question: Thinking about getting one of these. Any feedback on the implications of running the stove without it turned on? Do you foresee any issues with overheating the coil (much like running a boiler dry if you catch my drift)? Cheers,
Interestingly the only issue is that the silicone tube, feeding the air, will dry out quicker. But it’s replaceable anyway and often someone will move the pump out of the room and use a copper pipe, so it’s no issue. I’m planning to abuse mine as much as possible over the coming years to expose its faults. But so far there is no issue that I’ve found or Recoheat have told me about.
@@kevinhaworth5935 Very true! The question came from the feedback that they can be a bit noisy when running at full temp. Without knowing how loud it's difficult to say if I'd want it running when sat in a quiet room. Although as the temperatures continue to fall I'm sure it wouldn't bother ne that much! 😅
@@kevinhaworth5935my pump has been installed outside which reduces the noise but the hissing sound from the heat outlet valve is still noisy, mind you I view it as the noise of saving money on wood fuel and central heating!
Hello - really helpful study of the Recoheat! The results you are getting are very encouraging! How do you think the Recoheat would work with a Burley stove? As these stoves have a convection system at the top of their stoves that recover heat and send this into the room with the help of convection through the top tubes. And the flue gases are (claimed by Burley) to be at a much lower temperature - so this may mean the Reco heat is less efficient/recover less heat? Has Recoheat done any tests on a Burley with potentially lower flue temperatures? Your thoughts?
The flue temperature differences will not be huge, the main advantage with the Burley is that the flue should stay cleaner even at a lower temperature (due to high efficiencies). I think that further up, the temperature maybe lower, but at the height of the Recoheat, the temperature difference will be very small.
@@TheTortoise Thanks. Burley make claims that the flue gas temperatures are very low, and to some degree this is backed up by their stoves preference for a tall flue/chimney - i think i read somewhere as low as 122 degrees as they exit the stove. This is maybe mainly theory? Not born out in practice? Not sure. burley.co.uk/wp-content/uploads/2016/01/How-it-Works-The-science-behind-the-stove.pdf
@@Simon-vp3st that may be theoretically true in a lab with perfect conditions, but these results will vary hugely. The reason it doesn’t necessarily matter is because a lot of the heat is due to the fact that the stove is directly attached to the Recoheat so the temperature of the metal will get a lot higher. It is interesting though because when I tested the Butley Thorncombe I didn’t notice any particular differences. Obviously I use a flue thermometer to measure temperature and the temperatures were precisely where I expected them to be, so their claims do seem a little strange???
@@TheTortoise Nothing beats common sense and real world experience in my book...i am with you all the way :) I think Burley make good stoves, but i totally agree with you...a home is a long way from the laboratory - well mine is anyway!
Hi, Could you kindly do a video showing the pros and cons of burning wood vs burning anthracite? Thanks, and keep up the good work with your very informative channel
Yea they’re great particularly when your stove is in a fireplace. They drive all the heat out and circulate the room, so it definitely speeds up the heating of a room!
@@TheTortoise Hi, that's what I was going to ask, I have a stove top fan running constant and when I want to move the heat quicker I just use a 12" floor fan pointing at the stove. Would this device be substantially better than this? Thanks for the vids!
@@rhine2005 I think this is substantially better, because it is additional heat. The fans will move existing heat and increase the affect across the room. But this will not only do that, but also give additional heat (roughly 1 kw).
Houses with mechanical heat recovery do not gel well with stoves. You would definitely need to directly vent the stove through the back on an outside wall. If you look for a stove with “direct air”, and place it on an outside wall then this is a good first start. You would then ideally set the heat recovery system to pressurise the room with the stove as this will force the smoke up the chimney when you open the door. It will be worth chatting to the heat recovery installer and stove installer about this, so you can tailor things to be safe and work well in your situation.
Everyone’s electric will vary in cost, but roughly speaking if you ran it for 1 week then you would use the same electricity as you would boiling your kettle once. In other words, the consumption is tiny.
I can see this was uploaded a couple months ago when temperatures were perhaps slightly more mild. What temperatures do you achieve now, now that it's very chilly out? P.s for a house with single glazing, no heating used and poor insulated doors etc, 20/19'c is fantastic! We also have an older property (1900's) double glazed other than original front door and we're achieving around 18'c downstairs with our 5kw ecosy+ stove.
Yes it will. However flue temperature is generally lower with a boiler stove, so it’s effectiveness will be heavily determined by how you run it. If your stove is on low and slow 24/7 then it will have some affect, but not tremendous. If however you run your stove a bit hotter then it can delivery it’s heat very effectively through the room and out into other spaces too.
Not really. This is the hottest point on a flue so soot production will be at its very lowest. Bear in mind if a stove is used sensibly then even the top of the flue (the worst point) will have hardly any soot at each annual sweep.
I will have a look, but if it is helpful to say, this stove appears to be a relative low cost import (low cost to import at least). There are simply tons of these and very often many of them are the same stove with some aesthetic changes. This stove will operate very similarly to many other imports such as the Saltfire stoves, Woodford stoves, ACR, Mendip stoves, F2 (to name just the few that I have reviewed). They’re all generally quite good, so it’s not that imports are bad, but they do tend to be at least similar in: performance, obviously build quality and fuel economy. The Penman is an all cast stove, so likely to have a shorter life than the other steel imports, but equally it will be more characterful and interesting aesthetically.
@@TheTortoise Ok thanks for your quick reply. The reason I ask is that I own this stove, and wanted to know other peoples opinions of it. I hear people saying they can last upwards of 10-15 years. But what exactly is the issue which causes them to fail? And is there anything that can be done to enhance there lifespan? And are these stoves rebuildable in anyway? Thanks Mike
@@TheGoose81 I don’t expect terrible longevity issues, but it will be almost impossible to rebuild successfully after years of use. The good news is it seems they give a lifetime warranty which I would suggest means that if there were an issue they would replace the product as long as you had complied with their conditions. The chances of it being refurbished after more than 5 years for sure, is incredibly unlikely. I don’t think you’ve got anything to worry about, so just enjoy it. Like the others I’ve reviewed, it’ll do a great job and the warranty certainly gives peace of mind.

How loud is the air conditioning Ming out of the flue. Is it possible to measure the decebels
I’m doing a bit more playing with this on a big stove at the moment, so I will include some sound clips with other things to give a comparison.
In the room we have a vent coming from our Heat Recovery Ventilation - (There are no window vents) would this be sufficient to vent a small ESSE stove
