Versatile & portable climate solutions

Master BV77 indirect space heaters are built with a robust outer casing, stainless steel combustion chamber, and high quality components. They are designed to offer longevity, reliability, and safe heating. As a result of the tough exterior, these space heaters are ideal for any application and can withstand harsh conditions. They are mounted on a robust trolley frame with sturdy handles and highly durable wheels. The trolley makes the Master BV77 a highly portable space heater that can be moved easily to where it will be most effective. Indirect heaters are versatile machines. They can be used within a space with the flue installed through a wall to exhaust the fumes outside. They can also be used outside of the space with ducting used to vent the warm air directly into a space while the fumes are safely exhausted away separately.

Analogue thermostats, ducting lengths & more

Master BV77 space heaters are compatible with a range of fantastic accessories. Master produce flues, rain cowls, analogue thermostats, duct adaptor rings, and PVC ducting available in 3m or 7.6m lengths. The flues and rain cowls allow you to safely exhaust the fumes while protecting the internal parts from rain and general ingress. The adaptor rings and ducting allows you to duct heat into different locations directly. The thermostats offer you a level of control over the ambient temperature of a room before the heater shuts off automatically. If you are interested in a Master BV77 indirect fired heater plus accessories, we do also sell small Master space heater packages. Our heater packages include the space heaters plus all the accessories needed for a versatile climate control system with free delivery. You can even choose optional upgrades to exchange the analogue thermostat to a digital model, and add a durable rain cover. The rain cover prolongs the quality and performance of the heater and can be used for when the heater is in use as well as when it is in storage.
