DELTA 3 Plus Power Station 1800W X-Boost 3600W - Expandable to 5kWh

Only if the appliance is DEFRA approved — look for the DEFRA mark on this page. Under the Clean Air Act most UK towns and cities are smoke control areas, where you may burn smokeless fuel, or wood in an appliance DEFRA has exempted. Burning wood in a non-exempt stove in one of those areas can carry a penalty from your local authority. Gas, electric and bioethanol fires are not affected by smoke control rules.

As a rough guide, measure the room in metres, multiply length × width × height and divide by 14. A 5m × 4m room with a 2.4m ceiling gives about 3.4kW. Most British living rooms land between 4kW and 6kW. Oversizing is the common mistake — a stove run too cool tars up the flue and blackens the glass. Well-insulated or new-build homes should size down; a draughty solid-wall cottage should size up.

You do, or an installer you appoint — we supply the appliance only and do not offer or arrange installation. A solid fuel appliance must be installed to Building Regulations Document J and signed off; a registered installer (HETAS or equivalent) can self-certify, otherwise you must notify building control before work begins. Gas appliances must by law be fitted by a Gas Safe registered engineer. Bioethanol and electric fires need no flue and no notifiable work.

That depends on the appliance and on your chimney, so have your installer confirm it before you order. As a general picture: into an existing masonry chimney a stove normally needs a flexible stainless liner sized to its flue outlet; with no chimney, a twin-wall insulated system can be run internally or up an external wall; a balanced-flue gas fire needs only an external wall; and bioethanol needs no flue at all, only adequate room ventilation.

Boxed on a pallet, kerbside, on a tail-lift vehicle to the nearest hard standing — free to UK mainland on orders over £500. Stoves are heavy, so have two able people ready to move it from the kerb. Highlands, islands and Northern Ireland run on a longer schedule with any surcharge quoted at checkout.

Everything we sell is new, genuine UK stock and carries its manufacturer's warranty, which you register with the manufacturer after installation. Wearing parts such as rope seals, glass, baffles and grates are consumables and are not covered by warranty — we can supply them for the models we stock.
