Hi I have got two of these, the 4 and 6kw. I bought them 2 years ago direct from the factory. It was well worth the trip up to see them as I got to see the guys building them which is a rare thing this day and age!
We made our decision as the efficiency was listed as 82%. We were a little sceptical after always having the traditional style stove. Our new house is a bit too modern for an old style stove.
The stoves from vesta are extremely well built and and we have had great results from them for 2 seasons of burning.
We did quite a lot of research because we didn’t know if we should get a multifuel conversion for the stoves but after reading about how the efficiency drops if you burn wood on a multifuel stove we decided against it.
I can say that from our experience the vesta stoves have been fantastic addition to our home and throw out a huge amount of heat. We should have probably gone for 2 x v4 stoves as the v6 almost heats the whole house.
hope this helps.
