High lip?

[youthoftoday]

The "Stoves in Boats" guide is full of all kinds of useful numerical suggestions about dimensions for stove and hearth fitting, but baulks at the lip of the heart, suggesting a hearth should have a

 

high lip

 

What does this mean? 5cm? 10cm? 15?

 

Why don't the recommend a dimension?

 

What size is yours? What would you recommend?

Mine does not have a hearth lip .

A relevant distance would be edge of hearth from front of fire as coals etc. can bounce when they fall out.

However you are there opening door so always have shovel to hand to scoop up any ember that trys to escape.

About 5mm in the case of mine.

It may be worth leaving a small gap to allow the hearth to be swept out, if the regs will allow this.

Vacuuming where there might be hot stuff isn't a good idea, but if there's no gap in the lip it's very hard to clean properly with a brush and pan.

We have an Invicta woodburner in the kitchen. It has next to no lip so that as you open the door, it carefully deposits a quantity of ash or embers on the floor. Partly because of that, we are in the middle of having a new system fitted, with an MBS thermovulkan plus, which is as big as it sounds. And has a good lip at the front of the fire basket.

Once again, this is where a look at the full BS 8511 document gives much more info than the Soliftec drawing which is just a precis of it. The Soliftec drg at least is free to look at but 8511 either costs an arm and a leg or requires you to go through many hoops to get access to a copy!

 

From my studies of it (after I went through the hoops!), there is a trade off between hearth area size and upstand (lip) height. The upstand can be zero for 225mm distance from hearth front edge to stove front, but if it is increased to 12mm, 25mm or 50mm the hearth front edge to stove front distance can be reduced to 200mm, 150mm or 100mm respectively.
