Opus Calypso Woodburning Boiler Stove

Opus Calypso Woodburning Boiler Stove

The Opus Calypso stands out as a robust wood-burning boiler stove, compliant with the latest SIA Ecodesign regulations—truly a distinctive offering in the industry. Boasting a total output of 8.3kW, it efficiently allocates 3.4kW to the room and 4.9kW to the boiler, making it capable of heating water for radiators or showers for a standard sized living space.

Featuring an open-fronted log store for convenient log storage and a small cavity above the firebox to keep a kettle warm, the Opus Calypso combines practicality with style. A sleek chrome handle is positioned on the right side of the curved door, and the large glass viewing window is kept impeccably clear through a robust airwash system.

With a spacious internal firebox accommodating logs up to 330mm in length, this stove allows you to relish the flame pattern for extended periods. Take full control of the burn rate with two air control levers conveniently located just beneath the door.

Wood needs high temperatures and a precise supply of oxygen to burn. Opus stoves are designed to optimise the burning conditions in the fire chamber.

PRIMARY AIR:
Supplied from below the burning wood and used as a ‘boost’ for starting the fire, or when you have added fresh logs.

CONVECTION: FOR AN EVEN HEAT
An Opus stove has two outer layers with an air gap between them. Cool air is drawn up from the floor, heated by the body of the stove, and then released out through holes at the top. This makes for a more even spread of heat in the room and keeps the body of the stove a little cooler.

SECONDARY AIR:
This preheated air flows down the inside surface of the window, feeding the fire and keeping the glass clean. Once the stove is hot you control the burn rate by adjusting this secondary air.

TERTIARY AIR:
Preheated air enters higher up at the back of the fire chamber through a series of holes. Look here for dancing, floating flames as the gases given off by the wood combust.

INTUITIVE AND SIMPLE CONTROLS
Two easy to use levers give you full control of the burn rate of your stove

MULTI-POINT DOOR CLOSURE
Our cylindrical models all have a 2 or 3 point door mechanism, giving a positive feel and a firm closure.

DIRECT AIR: NO MORE DRAUGHTS
All Opus stoves can be connected to an external air duct. The air needed for combustion is taken fromoutside the house, not from the room. This reduces draughts in your home, helping to preserve valuable cosy heat.
