How to choose your pellet insert

Installing a pellet insert increases the energy efficiency of your home while maintaining the aesthetic appeal of the flames. However, pay attention to the following criteria to choose the best pellet insert for you.

#1 - The dimensions of the insert and the fireplace

The size of your fireplace is an important criterion. To avoid heavy work, choose a pellet insert that is smaller than your fireplace

. In this way, you can embed the device without any problem. Of course, some minor masonry work is still required to fill the empty space.

Be aware that the pellet insert requires an electrical connection. Make sure you have enough room to prevent the electrical cable from overheating. The location you choose should also be close to an electrical outlet for easy connection.

#2 - The power

The

higher the output of the pellet insert, the more rooms you can heat without using a heat spreader. In 10 m² with 2.5 m ceiling height, count 1 kW for an average insulation, 800 W for a well insulated home or RT 2005 and 600 W for a very well insulated home or RT 2012.

To heat an area of 100 m², that is to say the whole house or at least most rooms, count 10 kW for an average insulation, 8 kW for a well insulated home or RT 2005 and 6 kW for a very well insulated home or RT 2012. For houses with poor insulation, review the insulation before installing a pellet insert. 30 cm of insulation should cost you 20 euros / m² installed.

#3 - Performance

It is

the ratio between the amount of heat returned and the amount of heat produced during combustion. Expressed as a percentage, the efficiency of a pellet insert varies from 70 to 95%

on recent models. This means that 70 to 95% of the energy contained in the wood is returned as heat.

#4 - Autonomy

This

criterion refers to the length of time you will not have to refill with pellets. On average, a 15 kg bag of pellets should be enough for one day in the middle of winter. Note that the autonomy can reach 24 h in continuous mode, even more with some modifications on the insert.

It is indeed possible to increase the capacity of the hopper of your pellet insert during installation. Specifically, this involves installing a drawer system

to create a small additional reserve above the device. In this configuration, the pellet reloading will be frontal.

The slide system

is the most recommended. It consists of a hatch placed on the side of the chimney and a slide acting as an auxiliary tank. With this system, the capacity of your pellet insert can easily reach 45 kg, the equivalent of 3 days of continuous autonomy.

#5 - The materials used

Prefer

inserts made of cast iron. Despite its high weight, cast iron offers great robustness and high thermal inertia

. Indeed, this material resists better to temperature changes while offering a uniform diffusion of heat. Steel, which is lighter, rises quickly in temperature but suffers from a lower inertia.

It's not just the material of the pellet insert that counts. You should also consider the material of the fireplace bricks

. Although fragile, vermiculite retains heat well. The chamotte is robust but suffers from a lesser inertia. As for cast iron, its resistance and thermal inertia quickly make you forget its weight.

Finally, don't forget to choose the insert's covering

. The right material will have a non-direct impact on the installation costs, the life span, the aesthetics and the ease of installation. Depending on your taste and budget, you will have the choice between stone, wood, marble, ceramic, aerated concrete, brick or metal.

#6 - The available features

In contrast to

wood inserts, pellet inserts are fully automatic

. The programming and the timer allow to light the pellets at the desired time. But be aware that the automatic ignition varies in quality depending on the inserts. In addition, a thermostat is often available to regulate the heat in the room.

The best devices offer 3 time slots, with a different temperature for each. Average quality pellet inserts only offer 2 programs each day. You should also consider the simplicity of the control panel. And the Wifi option allows for remote settings.

Pellet insert: What you need to know

buyingbetter.co.uk

It is not enough to consider the selection criteria for pellet inserts. The energy efficiency, compliance with current standards and possible financial aid are also important.

How a pellet insert works

The pellet insert is a built-in version of the pellet stove, which is also called pellet stove. You can install the insert in an existing fireplace or enhance it with a custom-made surround. The addition of fuel is done by pulling the surface on which the insert is mounted towards you.

Good to know, the addition of pellets should only be done when the fire is out. Otherwise, the high temperatures expose you to severe burns. However, you can add a specific drawer during the installation of the insert. This system will allow you to refill the fire with fuel from time to time.

Heat diffusion

Pellet inserts make a noise that can be annoying. In the case of a ventilated pellet insert, a fan diffuses the heat frontally, which causes a noise of uncomfortable blowing at high speed. Note that the speed of ventilation of this type of insert varies from 1 to 5, the maximum speed should be used only in case of force majeure.

The ducted inserts have 1 or 2 additional fans, which allows a better distribution of heat to other rooms. On the other hand, more fans means more noise, even if the noise level is lower than with the main fan. Ducting is still an option on some conventional vented inserts.

The ultimate is the hydro pellet inserts. They are connected to the central heating so that they diffuse a small part of the heat directly into the rooms where they are located. This heat diffusion is done by ventilation or by natural air convection. Most of the heat is supplied to the water radiators of the house.

Standard and Green Flame label

Pellet inserts are governed by the standard NF EN 13 229 of the AFNOR. It defines the requirements for pellet inserts in terms of safety and energy production. Therefore, this standard allows to compare the efficiency of different devices and their degree of pollution.

To complement the standard, the ADEME launched the Green Flame label with the help of manufacturers of inserts. This label aims to reward the best appliances in terms of energy and environment via star ratings. If there are labels Flamme verte 5 or 7 stars, an insert of 4 stars is enough to receive financial aid.

About wood pellets, certifications exist. They allow you to choose quality fuels and to save money. In this regard, we strongly recommendusing pellets certified DIN Plus, NF biofuel pellets or EN Plus.

Financial aid

Pellet inserts reduce greenhouse gas emissions in a house. That's why the state provides loans for the purchase and installation. The ANAH (National Agency for Housing) via its program Habiter Mieux Agilité, can finance 35% or 50% of the total amount excluding VAT of the work according to your income. This aid is limited to 7 000 € and 10 000 €.

There is also the tax credit for energy transition, at a rate of 30%, with eligible expenses capped at between €8,000 and €16,000 depending on the case. Not to mention the eco PTZ, a loan whose interest is fully supported by the state!

Pellet insert or wood insert?

Each has its advantages and disadvantages. The wood logs cost less than the pellets and produce very beautiful flames. But the maintenance of a wood insert is demanding, not to mention the limited autonomy. Automatic device, the pellet insert has a greater autonomy and can operate 3 days in a row without refueling.

Maintenance of a pellet insert

buyingbetter.co.uk

Apart from lighting, refueling and extinguishing, a pellet stove requires regular maintenance to keep it running. Use an ash vacuum to clean the combustion chamber. This should be done 2 or 3 times a week. And take 5 minutes to clean the glass with a damp cloth.

For longer maintenance, follow the manufacturer's instructions. Over time, soot and debris build up in the flue pipes. To reduce the risk of fire, sweep the flue pipe and chimney at least twice a year, once during the heating season.

The log insert or the pellet insert

The Log Insert

The log insert is still a very popular solution because of the efficiency and safety it provides. From the safety point of view, it will avoid any projection of sparks or twigs, thus minimizing the risks of fire.
As for its efficiency, a log-burning fireplace can reach 80% compared to 15% for open fireplaces. The most important thing is that thanks to this innovation, you will be able to optimize the heat in your interior without using too much wood.
However, it is necessary to remain realistic, because a log fireplace requires a daily cleaning of its windows. With the wire of time, it is very likely that its output decreases up to 60 %. Finally it is necessary to envisage a rather important place as for its installation.

The pellet insert

Many households make the choice to turn to a pellet insert because of the comfort it provides. On the one hand, it is easy to switch on and is programmable. Once the desired temperature is reached, this device stops distributing the pellet, thus minimizing the risk of fire. On the other hand, if the temperature drops, its thermostat will automatically restart the fire.
The only thing you can reproach it with is that it must operate with electricity.

Verdict

Choosing between a log burner and a pellet burner is never easy. So if you want to enjoy natural women then the log insert remains the best alternative. On the other hand, if you want to regulate the intensity of the temperature according to your desires, then the pellet insert is best for you.

Why buy a pellet insert?

The pellet insert is the ideal solution to replace a traditional fireplace. The device offers a better autonomy, automatic operation, adjustable temperatures, easier maintenance and a successful aesthetic. Here are the reasons why you need a pellet insert.

Optimal heat distribution

Despite its aesthetic and authenticity, the old fireplace with an open wood fire does not allow for optimal distribution of the heat produced. The opposite of a pellet insert. Built into a corner fireplace or a central fireplace, the device distributes the heat automatically. You can even adjust the temperature!

Aesthetics that can be customized to your liking

The insert is a built-in appliance. This means that you can arrange the casing as you wish. Whether it's a contemporary style fireplace, a traditional fireplace or a modern, designer fireplace, you are free to choose the material of the fireplace bricks or the materials used for the cladding according to your taste and budget.

High energy efficiency

Know that a pellet insert can multiply by 5 the output of your fireplace. In addition, pellets are the cheapest fuel after wood logs. Not to mention that the energy efficiency of the best pellet inserts exceeds 85%, which is higher than the efficiency of a log insert.

A profitable investment in the long term

The wood pellet costs 6 cents of euro the kilowatt-hour, against 15 cents of euro for electricity. As an example, a house of 100 m² averagely insulated consumes each year 1 ton of pellets or 65 bags of 15 kg. In total, this will amount to 300 euros TTC over 1 year. In addition, the inserts rated 4 stars or more can benefit from financial aid for purchase and installation.

Practical device in use

The pellet insert retains the soot and ash, unlike a fireplace. So you won't have to sweep up in front of it! In addition, the closed design of inserts limits the risk of fire and carbon monoxide poisoning. And some pellet inserts have a double combustion system to burn the gases from the first combustion, which reduces pollution and waste.

Tips

Don't forget to take into account the costs of installation and pellets.

If you take the plunge and decide to buy a pellet fireplace, don't just consider the price of the appliance. Installation work will be required as well as the hiring of professionals to carry it out. The operating cost and the maintenance cost are also to be taken into account.

Clean regularly with an ash vacuum cleaner.

Think about

purchasing an ash vacuum to thoroughly clean debris and ash in your insert. Don't forget to vacuum critical parts like the tray and fan. Clean as often as the operating instructions require.

Remove the ash briquettes formed in the firebox.

For some

reason, some ash clumps may harden. This can interrupt the air flow and cause inefficient combustion in the firebox. As a result, you must remove these ash briquettes during maintenance.

Install a pellet drawer or slide for greater autonomy.

The

drawer system provides a small additional supply above the insert. The refill is then done from the front. The slide-in system offers more capacity. The pellets go from the extra tank to the insert through a hatch on the side. Thanks to this system, your insert can work 3 days continuously.

Keep the noise to a minimum.

The

insert's built-in design requires a fan to cool the unit. It is this fan that makes noise. You cannot uninstall this system, but it is still possible to adjust the fan speed independently of the power. Avoid speeds 4 and 5, unless really necessary.
