I think we have discussed this before somewhere........
I have one lurking somewhere. Bought it to use in a (new) log burner at a previous place because I cant have real wood burning for health reasons.
It worked okish. It did give off a slight smell but I am super sensitive so someone else may not notice it.
I thought it quite expensive both to buy and use. Eventually I will get round to using up all the bottles of fuel I still have, probably use it outside in a chimea or something. For inside at this house I am going for the optimist water/electric, no fumes, flames or hassle.
If I were you I would buy a stainless steel unit as they come with a cover to kill flames etc. You can put it into any setting/surround you choose.
It may affect the MVHR as it does need oxygen, Im no expert on flames and air mvhr....no doubt someone can advise.
And I’ll still wager that Scottish Power are worse. Still have no bills since Nov 17, and it says I last took a meter reading 230 days ago when I did it last Sat. And this morning 10 letters turned up all addressed to my deceased husband and I. I have been asking them to remove his name from the account for over 2 years and I keep being assured that it’s done. Absolute shambles of a company!
