The Finnish company produces Harviya stoves in the form of wood-burning stoves with a natural flame or electrical installations of various capacities, steam and infrared booths. The buyer acquires a reliable unit that lasts 10-15 years. The Harvia stove is mounted on the floor or wall, available in a cylindrical, round, rectangular shape.
Product Purpose
The Harvia stove is installed in a bath, sauna or steam room, heats the room and creates a humid atmosphere for relaxation and relaxation. The principle of prolonged combustion of fuel is used, heat is supplied through the convection channels of the built-in exchanger. The temperature in the rooms in the neighborhood rises with the help of additional ducts. There are models of Finnish Harvia bath stoves with built-in tanks for heating liquids.
Electric heaters are heated in a given mode, which is coordinated by remote controls. A power supply lock is provided if the user forgets to turn off the unit. Steam generators are designed to create high humidity at low temperature in the room.
Varieties of furnaces
Models of heating equipment differ in technical characteristics, appearance and principle of operation.
The design of the Harvia stove has standard elements:
- the furnace compartment, which is made of heat-resistant metal 10 mm thick, contains stones or an electric heater;
- a device for removing gases and smoke removes combustion products and creates additional heat transfer.
The wood-burning stove for the bath contains a heater and a network of convection collectors in the design. The portable firebox is mounted in a niche or dressing room for a separate fuel supply. The doors of the combustion chamber are made by heat-resistant glass.
Wood burning stove
The principle of pyrolysis underlies the operation of equipment. Carbon dioxide is released during the combustion of fuel at a stable temperature and limited supply of fresh air. The substance enters a separate chamber and burns out, generating additional heat.
Harvia sauna stove works as follows:
- firewood is placed in the furnace below the stove, solid residues wake up in the blower;
- heat is produced in the main chamber and afterburning section, then it enters the channel system and heats the stacked stones, water in the tank;
- used gas is removed through the pipe outside the room.
Models of the Harvia sauna stove are equipped with chimneys of different designs and materials for a convenient combination with any interior of the sauna. Barriers and bases are used for safety and protect close walls, ceiling and floor from overheating.
Electric heaters
The design contains a housing, a layer of heat-insulating material, a control unit and PETN. The electric-generating principle of the Harvia sauna furnace allows heating stones without solid or liquid fuels. The temperature in the bath rises after pressing the button on the remote control. The unit heats the air and the built-in water tank.
The control unit is installed outside the steam room and regulates:
- the degree of glow of the electrical element;
- the duration of the heater;
- unit turn-on time, which can be delayed for a certain period.
The panels are mounted on the wall in the waiting room and do not require much space. The power of electric ovens is calculated for small rooms, family use rooms or commercial professional saunas.
Steam generators
Units increase humidity to 40-60 g of water per 1 kg of dry atmosphere in a bath at a temperature of + 40-45 ° C. Steam nozzles are not included in the kit when they are sold, because their number and type changes depending on the purpose of the generator.
The flavor is supplied to the room by mixing the concentrate of the substance with steam. The smells of eucalyptus, needles, passion fruit are used. The compact device is mounted in a limited space, the work is regulated by a control unit with a touch screen.
Additional devices regulated by one unit are connected to the nodular steam generator if a sauna from several rooms is used.
Features of choice
Harvia stoves for a bath are selected based on a power of 1 kW per 1 cubic meter. m area, but non-insulated rooms require clarification in the calculations. Uninsulated surfaces of walls, windows, doors give off heat, so the stove will need more power. Each uninsulated square of the floor ceiling area and fences adds 1.2 cubic meters to the volume. m, and in a bath with walls made of logs without sheathing, the result is multiplied by 1.5.
Ventilation provides fresh air and comfort, but removes heat, so it is taken into account when choosing power. The mass of stones affects performance. 5-7 kg per 1 cubic meter is recommended. m room. Furnaces are purchased with a capacity that exceeds the estimated figure by 10-15%. This is due to fluctuations in mains voltage, changes in outdoor temperature in summer and winter.
Advantages and disadvantages
The chamber capacity holds up to 200 kg of stones, therefore the productivity and the rate of vaporization increase.
Units are sold for rooms of any size, inside there is an air flow separator for better heat supply. The materials used are environmentally friendly, high-strength steel with heat-resistant qualities is used.
Customers do not like stoves because of the large convection, but the problem is solved by making brickwork around the unit at 1 m. The high price scares some users away.
