We have a Morso Badger 5Kw. By controlling the ventilation we can moderate the burn times. A half open vent keeps the give enough flame and heat to keep the room warm & glass clean.
We buy 1 cubic metre of seasoned logs for £55. Its has lasted 8 months, supplemented by random offcuts. Occasionally, we add coal if we want have a warm fire in the morning.
My opinion dry(20% humidity) logs and practice. You’ll get it wired.
We removed the radiator thinking stove would make up for it, but we have now got he rad back on. Its just handy to have.
