The Finnish company produces Harvia stoves in the form of woodburning stoves with a natural flame or electrical installations of various capacities, steam and infrared cabins. The buyer purchases a reliable unit that lasts 10-15 years. The Harvia stove is floor or wall mounted and is available in cylindrical, round or rectangular shapes.
Purpose of products
The Harvia stove is installed in a steam room, sauna or steam room, heats the room and creates a humid atmosphere for relaxation and relaxation. The principle of long-term fuel combustion is used, heat is supplied through the convection channels of the built-in exchanger. The temperature in the neighboring rooms is increased by means of additional air ducts. There are models of Finnish Harvia sauna stoves with built-in tanks for heating the liquid.
Electric heaters are heated in a preset mode, which is coordinated by remote controls. It provides for blocking the power supply if the user forgets to turn off the unit. Steam generators are designed to create high air humidity at a low room temperature.
Varieties of ovens
Heating equipment models differ in technical characteristics, appearance and operating principle.
There are standard elements in the design of the Harvia stove:
- the furnace compartment, which is made of heat-resistant metal 10 mm thick, contains stones or an electric heater;
- the device for removing gases and fumes removes combustion products and creates additional heat exchange.
The wood-burning stove for a bath contains a heater and a network of convection headers in the construction. The remote firebox is mounted in a niche or dressing room for separate fuel supply. The manufacturer makes the doors of the combustion chamber from heat-resistant glass.
Wood burning stove
The principle of pyrolysis underlies the operation of the equipment. Carbon dioxide is emitted during fuel combustion under conditions of stable temperature and limited fresh air supply. The substance enters a separate chamber and burns, releasing additional heat.
The Harvia sauna stove works as follows:
- firewood is placed in the firebox at the bottom of the stove, solid residues spill into the blower;
- heat is produced in the main chamber and afterburner section, then enters the channel system and heats the stacked stones, water in the tank;
- used gas is removed through a pipe outside the premises.
Harvia sauna stove models are equipped with chimneys of different designs and materials for a convenient combination with any sauna interior. Guards and bases are used for safety and protect the nearby walls, ceiling and floor from overheating.
Electric heaters
The design contains a body, a layer of heat-insulating material, a control unit and a heating element. The electric generator principle of the Harvia sauna stove allows heating stones without solid or liquid fuel. The temperature in the bath rises after pressing the button on the remote control. The unit heats up the air and the built-in water tank.
The control unit is installed outside the steam room and regulates:
- the degree of heating of the electrical element;
- the duration of the heater's operation;
- time to turn on the unit, which can be postponed for a certain period.
The consoles are mounted on the wall in the dressing room and do not require much space. Electric stoves are rated for small rooms, family rooms or commercial professional saunas.
Steam generators
The units increase the humidity up to 40-60 g of water per 1 kg of dry atmosphere in a bath at a temperature of + 40-45˚С. Steam nozzles are not included in the sales kit, as their number and type varies depending on the purpose of the generator.
The fragrance is supplied to the room by mixing the concentrate of the substance with steam. The smells of eucalyptus, pine needles, passionfruit are used. The compact device is mounted in a confined space, the operation is regulated by a control unit with a touch screen.
Additional devices are connected to the nodal steam generator, regulated by one block, if a sauna from several rooms is used.
Features of choice
Harvia stoves for a bath are selected on the basis of a power of 1 kW per 1 cubic meter. m of area, but non-insulated premises require clarification in the calculations. Uninsulated surfaces of walls, windows, doors give off heat, so the heater will need more strength. Each non-insulated square of the ceiling area of the floor 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, therefore it is taken into account when choosing the power. The mass of stones affects performance. Recommended 5-7 kg per 1 cu. m premises. Furnaces are bought with a capacity that exceeds the calculated figure by 10-15%. This is due to fluctuations in the mains voltage, changes in outdoor temperature in summer and winter.
Advantages and disadvantages
The capacity of the chamber holds up to 200 kg of stones, therefore, the productivity and the rate of vaporization increase.
The units are sold for rooms of all sizes, inside there is an air flow divider for better heat supply. Materials are used environmentally friendly, high-strength steel with heat-resistant qualities is used.
Buyers dislike stoves because of the large convection, but the problem is solved by making 1 m of brickwork around the unit. The high price discourages some users.
