Wood-fired workshop heating

The workshop or site heater is a mobile device.
It is used as a primary or auxiliary heat source, and is adapted to generate a stream of warm air.
These devices can be made more efficient by combining them with other specific accessories.
Workshop heating equipment comes in many forms.
However, wood-fired models offer a number of advantages, including good value for money.

What was the customer’s need?

Find an economical heating solution for your carpentry workshop in Tarbes.
The building has a surface area of 800 m2 and a height of 5 meters.
The building is well insulated.
The desired temperature is 12 to 15°.

Polypoles proposal

In view of the ever-increasing cost of fuel oil and gas, we proposed a wood-fired generator. In this way, the customer can convert his wood offcuts into energy.

Solutions provided by Polypoles

The F range wood furnace is the ideal economic solution for our customer’s business.
It delivers heating quality on the same scale as a traditional installation running on fossil fuels such as oil and gas.

• Installation of a FABRI F115 kW wood furnace
• Installation of a Ø 180 double-skin smoke pipe

The generator was installed inside the workshop using bulk blowing technology, and we connected the smoke system to the outside. To find out more about these innovative solutions and how they can meet your energy needs, visit our biomass boiler page.

Why use wood heating?

Wood heating is one of the most widely used types of heat-generating equipment.
Both ecological and economical, wood-burning heaters are particularly efficient and guarantee a long service life.
They are equivalent to any other type ofheating equipment, such as condensing gas boilers or heat pumps.
Wood-fired heating offers a considerable reduction in energy consumption, while remaining an environmentally-friendly solution.
The design aspect is particularly striking in stoves and fireplaces.
You can also regulate the temperature with a biomass boiler, heat pump or other systems.
Although wood-burning appliances are environmentally friendly, it is possible to reduce emissions even further thanks to double combustion.
This is a process that increases the calorific value of wood.

It works in conjunction with certain wood-burning stoves or log-fired boilers.
The aim of these appliances is to provide a second puff of air, to return the gases from the first combustion to the flames.
In this way, energy consumption and gas emissions are considerably reduced.
Wood-burningworkshop heaters are designed for industrial environments, carpentryworkshops and repair shops.
Specialists in cabinetmaking, metalwork or ironmongery also opt for this solution.
Wood-burning appliances are available for use in the home.
Those designed for use on building sites have a large volume corresponding to the power required.

Choosing the right wood-fired workshop heating equipment

Before even considering the type of equipment, it’s imperative to have a precise idea of the volume of air to be heated. Indeed, the choice will depend in part on this last aspect. You also need to take into account the location of the workshop, its level ofinsulation and its configuration.

Volume of air to be heated

Generally speaking, in workshops, the volume to be heated is quite large.
The unit’s heating power will therefore be proportional to the size of the workshop.
Expressed in Watts, power is defined according to the volume in m³ of the workshop to be heated.
In practical terms, the standard formula for benefiting from the heater’s performance is as follows: 1m³ of air=40 watts of heating power.
The calculation is based on height and surface area.
So, 1m² of surface to be heated = 100 watts of power.
For a poorly insulated location, you’ll need to add 15% of this power to get a proportional result.
Depending on the volume, air destratification is recommended for optimal mixing.

The different types of wood-burning workshop heaters

Given the volume of air to be heated, it’s much more practical to use wood furnaces or woodpellet/biomass furnaces.

Workshop stoves hot air generator

Workshop stoves are heating appliances that work by blowing large volumes of air into rooms.
They rapidly propagate heat throughout the interior space.
They are ideally suited to car garages, carpentry workshops, warehouses and many others.
They work in a similar way to radiant fireplaces . At Stoves, on the other hand, radiate much more heat.

Wood-fired furnaces

Wood-fired furnaces are the most efficient.
They spread heat over the entire workshop volume with a high flow rate.
Also known as wood-fired forced-air boilers, they are specially designed for workshops, ovens, warehouses and all kinds of large spaces.
They run on wood alone, reducing energy costs.
They also feature a fan for even heat distribution.
Wood-fired furnaces can also be used for drying operations.
And because they run on wood, the purchase price is quite affordable compared with other energy systems.

The pellet furnace

As far as the pellet-fired furnace is concerned, it’s by far the least expensive manual-loading version, and requires no complex system. It’s a warm-air heating system with a built-in radiator/heater . It works exclusively with wood pellets or biomass. The stand-alone version is more expensive because of all the on-board automatic systems.(auger, temperature control, ash extraction).

Wood fuels you can use in these workshop heaters

For workshops that have opted to use wood-burning stoves and furnaces, wood and wood waste fuels are very welcome.
The temperature of these products remains above 900 degrees.
Solid-fuel furnaces are compatible with wood and wood waste fuels: wood chips and coal.
Wood pellet furnaces, as their name suggests, run exclusively on wood pellets.
For safety reasons, regulations insist that waste wood containing glue, varnish or similar substances must not be burned.
Burning them could damage human health or the ecological balance of the environment.

Other energy sources for workshop heaters

In addition to wood-fired workshop heaters, there are also electric workshop heaters, gas-fired workshop heaters and oil-fired workshop heaters. Of all existing workshop heaters, fuel oil heaters are the most powerful. Also known as hot-air guns, they are powered by electricity. The sheer size and weight of such devices cannot go unnoticed. There are two types: direct combustion and indirect combustion. The first is much more practical for larger rooms, while the other offers greater flexibility. Whichever type of oil-fired workshop heater you opt for, the price remains high. At the same time, wood-fired workshop heating offers the same advantages at a much more affordable price. What’s more, it’s a renewable energy source. That’s why it’s so much cheaper to opt for a wood workshop heater.

Biomass” renewable energy

Wood-fired generators are known for burning this fuel, but biomass heating biomass heating opens up new energy sources that are little-known to the general public.

• Olive stones, cherries, prunes, peaches, apricots, nectarines
• Almond or coconut shells
• Miscanthus
• Grape seeds
• Vine beds

For wood: forestry pellets or chips(P31 – ISO 17225 standard)
