Hot tub heater

The set includes a 2-metre stainless steel chimney, a connection kit for attaching the heater to the tub, hoses and hose clamps.
The external marine-grade aluminium heater takes logs up to 50 cm long. Wood briquettes heat the water faster.
When the heater is in use, the chimney and heater door become hot. The other surfaces of the heater stay at the same temperature as the water in the tub.

Heating time also depends on the season. The tub can take considerably longer to heat in winter than in summer.
