Small on the outside, big on the inside.
Harvia Delta is a powerful package for a small sauna. It is a compact and efficient heater with a large stone space. The stainless outer casing of the heater gives your sauna a modern look. The triangular design allows Delta to be installed in a corner, improving the efficiency of space utilisation in the sauna. The heater is easy to mount on the separate mounting rack included in the delivery.
Delta models D23 and D36 are equipped with a built-in control unit. The models D23E and D36E are controlled by a separate control unit.
