multifuel stove with back boiler – Inter Tek’s website –
A multifuel stove that has a back boiler can heat radiators as well as supplying hot water to the house. This could reduce heating costs.
Installing a wood burning stove with a built in back boiler to an existing central heating system is relatively simple and can be accomplished by a qualified plumbing engineer. This article will show you how.
Features
When a stove is equipped with a boiler, the heat produced from burning wood or other fuel is used to heat water in a hot-water cylinder as well as to heat the space. A boiler stove is also able to heat radiators in the home. We have a large variety of multifuel stoves, including back boilers. All come with a full manufacturer warranty.
A standard wood stove emits heat in one direction as it passes through the flue outlet from the firebox. Multifuel stoves with a back boiler generate more energy because the heat is distributed across multiple directions more efficiently. This means more heat is directed towards the room and less heat is lost through a flue outlet.
Once the heat of a multifuel woodburning stove that has a back boiler is used to heat the space, it is possible for this heat to be redirected elsewhere in the property through a pipe loop. This can be used to heat a hot water cylinder, radiators or even a nonpressurised shower. A thermostat is typically installed to check the temperature of the hot water tank and turn on the radiators’ pump when this level is reached. This will stop the hot-water cylinder from running out and ensure that there is a constant supply of hot water for domestic use.
The CSB multifuel stove with a back boiler has an impressive output of 21kw and can power a complete home using the central heating system or a domestic hot water cylinder. The CSB is a cast iron multi fuel stoves 5kw-purpose stove that can burn wood logs, anthracite, Briquettes, as well as smokeless fuel. Alternatively it can be run as a separate wood burner that is heated by thermosyphon technology. The CSB works with open and closed system type central heating installations (not compatible with pressurised systems). A CSB is equipped with a stainless-steel thermal store or neutraliser.
Fuel type
The difference between a multifuel stove and a boiler stove is that the latter comes with an inbuilt water tank that can be used to heat the hot water in your home and even radiators. This feature makes boiler stoves a popular choice for environmentally-conscious homeowners who want to reduce their reliance on gas, oil or electricity.
The most common kind of multifuel stove with back boiler is the wraparound boiler stove, which is equipped with an water tank that runs across the sides and back of the firebox. This means that the boiler section of the stove is able to effectively hug the firebox, thereby maximising heating efficiency and power output. Wraparound boiler stoves are available from a variety of top manufacturers, including Stratford and Hunter Stoves.
Another option is the clip-in stove, which comes with a water tank which replaces the firebricks located at the rear of the stove’s firebox. These stoves aren’t capable of producing large quantities of hot water, as the boiler tank has a smaller area than the wraparound boiler stove.
There are a variety of ways you can fit multifuel stoves that have an back boiler into your system, but the most common is by plumbing it as a radiator within a vented central heating system. This lets the boiler stove be a second source of heating by coming on when your gas central heating turns on and boosting the temperature.
Installing a wood-burning stove with a boiler back is also possible by connecting it to a multi coil hot water tank or heat accumulator. In this case, the stove will heat the hot water tank before transferring it to your radiators via an electronic thermostat. This installation is more complex and should only be carried out by a qualified heating technician.
A multifuel stove that has a rear burner that is not properly installed can be dangerous. When the stove is in use with water, the boiler can transform into steam. This could cause damage to the system to explode if it’s not properly vented to explode.
Fuel supply
The heat generated by the stove’s combustion could be transferred to a tank of water through a boiler unit that is integrated into the back. You can utilize the heat inside your home to lower carbon emissions and energy bills. This makes the stove more energy efficient because heat isn’t lost through the chimney. This type of stove is often called a wetback wood burning stove, or a back boiler stove.
Modern multifuel stoves that look attractive and come with a back boiler are equipped with a hot water cylinder that is pre-installed. This lets you connect the stove to your hot water system and use it to heat both your radiators and taps around the home. Some older models of boiler stoves have separate hot-water cylinders, or the boiler might be placed in a movable box that can be positioned over the fire chamber.
This model has a massive firebox, with a large ceramic window and an “advanced air wash system” to ensure the view. This stove is also equipped with both the top and bottom (Primary and Secondary) air vents to enable easy and effective control of the burn rate and heat output. Its chrome door handle and air controls provide a fashionable appearance to the stove.
When the stove needs more air, a thermostatic probe connected to the stove will open and close a second vent at the rear. This boosts the flow of air through the heat exchanger which boosts the output of room temperature.
The models of the ‘Elegance B’ have 4 water ports (2 x flow and 2 return) on the rear of the stove, these can be capped off when only one water heating circuit is needed. These stoves will heat up to 10 standard radiators as well as the domestic hot water system is installed correctly.
We offer a broad selection of wood-burning stoves that come with back boilers from the UK’s top manufacturers. We also have a broad variety of boiler stoves, thermal stores, and pumps for these models.
Installation
There are a variety of ways to connect a boiler stove to your central heating system. It can be connected to a combi boiler by using a special adaptor, or you can add a thermal storage that will allow your wood burning stove to feed the hot water system on its own (this requires an additional header tank that is located in the loft). You can also give priority to hot water by connecting radiator loops and heat loss radiators via injector tees to the stove and feeding the system from there. A thermopile thermostat could be used to control the pump in the loop for the radiator. This will ensure that the system operates only after the stove has heated the hot water tank.
Adding a wood burner with back boiler to an existing system can be fairly easy. It is dependent on the plumbing layout and the system you are using However, you can connect the boiler stove to many modern open vented systems without much disruption or cost. It is a good idea to seek the advice of a HETAS certified person or a local plumber installer who is experienced with wet systems prior to putting in multifuel stoves with back boiler.
A typical system would comprise a thermal store and an accumulator tank to store hot water and woodburners with a back boiler in the firebox. The stove is connected to the system by way of the back boiler water ports which are measured at 1 inch BSP (British Standard Pipe) and can be easily modified to fit the size of 22mm or 28mm pipes by using compression fittings available from the majority of reputable plumbing retailers.
The thermal store is a huge tank that has the capacity to hold an enormous amount of heat and is connected to the radiators as well as the stove via a system of pipes and tees. The radiator loop is controlled by a thermostatic switch, which only allows heating to come on once the hot water in the system has reached 55 degrees C.
The CSB small multi fuel stoves for sale-fuel wood burner with back boiler is a very popular option. It’s a powerful stove that can provide power to up to 10 radiators in your home. It can burn a wide range of fuels like coal, logs peat, smokeless fuel and peat. The CSB can also be used as an additional source of heat, such as a log gasifier or biomass pellet boiler.
