Hi All

I’m hunting for a design for a wood boiler / fireplace. Basically we want to install a wood fireplace in our main living room, which will provide some space heating but then also have a boiler heat water for the radiant slab heating we have. Looking for about 20kw output for the radiant system and a bit more for space heating the living room.

Most boilers tend to be ugly, and super insulated so they don’t provide much space heating.

I’ve been looking over the seton plans a fair bit, always wanted to build one, and am wondering if this concept could be modified. Maybe by adding a glass door and reducing the insulation around the sides of the unit adding tiles or something to make it look less utlaitiarian.

Has anyone ever done or seen something like this?

Pretty much you can either use the heat for radiant output of you can transfer it to water for hyrdranic but you cant have both. And a fireplace isnt going to mske much heat in either form.

By fireplace I mean some sort of wood burning heater... not an open fire.

Let’s say we wanted 30kw, 20 for radiant and 10 for the space... could a boiler not be made to leak a bit of heat?
