Ageing Hunter 6 double sided Multifuel stove

[Cliffclop]

Hi, 

I was thinking about changing my Hunter for a more modern stove, but given the prices, I'm having second thoughts, as there's nothing wrong with the stove, although it's been in about 17 years. I can refurbish it with new door rope and gaskets as they're still available.  My only concern is around the state of the flue. It's double skinned and is inside an existing chimney, it's swept once a year. and there's no evidence of anything wrong with it. The stove is used to burn mostly seasoned wood, with the odd load of smokeless anthracite, as a secondary heat source, along with oil.  Does the flue have a recommended life? any opinions would be appreciated.

Usually within a masonry chimney is a flexible flue liner,  unless your property is thatched that is what you are likely to have in place.   At 17 years old it will need to be replaced,  no installer is going to certify it as safe to use ,  it's just to risky.

 

Your old Hunter will be around 55 percent efficient,  many of the best stoves on the market todsy have an efficiency in excess of 80 percent,   this will mean that as long as the stove is correctly installed then you will use around 25 percent less logs for the same amount of heat.  

 

I would suggest that a 2022 compliant 5kw nominal heat output stove will do the job nicely and not require additional outside air ventilation that stoves with a nominal heat output of 5.1kw or more require. 

 

PM me if necessary.
