Multifuel Stove With Back BoilerA multifuel stove that has a back boiler can heat radiators as well as heating hot water for the house. This will save money on heating bills.
Adding a wood burning stove with a built in back boiler to an existing central heating system is simple and can be accomplished by a competent plumbing engineer. This article explains the process.
Here are some examples of
If a stove is equipped with an engine, the heat generated from burning wood or other fuel is used to heat water in a hot-water cylinder and to heat the space. A boiler stove is also capable of heating radiators throughout the home. We have a large selection of multifuel stoves with back boilers. All come with a full manufacturer warranty.
A typical wood burner puts heat in one direction when it moves from the firebox through an outlet for the flue. A multifuel stove equipped with back boilers can generate more energy since the heat is distributed across different directions in a more efficient way. This means that more heat is directed towards the room and less heat is lost through the outlet of a flue.
By running a pipe, you can transfer the heat produced by a multifuel woodburning fireplace with a boiler to another room. This could lead to the heating of the hot water cylinder or radiators, or even a shower that isn't pressurised. Typically a thermostat would be installed to keep track of the temperature of the hot water tank and switch on the radiators' pump when the temperature reaches. This prevents hot water from being depleted and ensures that the hot water cylinder has a steady supply of hot water available for domestic use.
The CSB multifuel with a back-boiler has a powerful output of 21, 000 watts and can be used to heat a entire home with the help of central heating system or even a domestic water cylinder. The CSB is a
multi fuel wood stove-purpose stove that can burn wood logs, anthracite coal Briquettes, as well as smokeless fuel. It can also be used as an independent wood burner heated by a thermosyphon. The CSB is compatible with both open and closed central heating systems (not compatible with pressured systems). A CSB is typically supplied with a stainless steel thermal store or neutraliser tank.
Fuel type
The main difference between a multi-fuel stove and the boiler stove is that the latter has a built in water tank that can heat your home's hot water 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.
Wraparound boiler stoves are the most popular multifuel stoves that have back boilers. They are equipped with a water tank that runs along the sides and back of the firebox. This means that the boiler portion of the stove effectively hugs the firebox, which increases the efficiency of heating and power output. Wraparound boiler stoves are available from a variety of leading manufacturers including Stratford and Hunter Stoves.
The clip-in boiler stove is an alternative option. It features a water tank which replaces the firebricks in the rear of the firebox. These types of stoves are not capable of producing large volumes of hot water, as the boiler tank has a smaller surface area than an all-round boiler stove.
You can put in a
multifuel stove which has an back boiler within your system in many ways however the most popular method is to pipe it as a radiator into the vented heating system. This allows the boiler stove to act as an additional source of heat by turning on when your gas central heating turns on and boosting the temperature.
Installing a wood-burning stove that has a boiler back is also possible by connecting it to a multi coil hot water tank or heat accumulator. In this scenario, the stove will heat the hot water tank, and then deliver it to your radiators through an electronic thermostat control valve. This is a more complex installation procedure and should only be carried out by a trained heating engineer.
When a multifuel stove fitted with a back burner is fitted incorrectly, it can be dangerous. When the stove is used with water, the boiler could turn into steam. This could cause damage to the system to explode if not properly vented to explode.
Fuel supply
The heat from the stove's combustion is transferred to a tank of water via a boiler unit that is built into the back of the stove. This allows you to harness the heat and use it to heat your home, reducing energy costs and carbon footprints. It also makes the stove more efficient since it stops heat from going up the chimney. This type of stove is also referred to as a back boiler or a wetback stove.
Most modern aesthetically designed multifuel stoves with back boiler feature hot water cylinders that have the heating unit pre-built into the body of the appliance. The stove can be connected to the domestic hot water system to heat your faucets and radiators. Certain older models of boiler stoves could come with a separate hot-water cylinder or they might have the boiler tucked away in an open box that can be positioned on top of the fire chamber.
This model features a huge firebox, a large glass window and an "advanced air wash system" to maintain a clear view. This large stove has both the top and bottom air vents (Primary and Secondary) to allow for simple but efficient control of the burn rate and output. The chrome door handle and air control give the stove a a stylish look.
If the stove requires more air, a thermostatic probe attached to the stove will open and close a second vent in the rear. This increases air flow through the heat exchanger which increases the output of a room temperature.
The models of the 'Elegance B' come with 4 water ports (2 flow and 2 x return) at the rear of the stove. These can be closed off when only one water heating circuit is required. If plumbed correctly these stoves are able to heat up to 10 radiators in average size and the domestic hot-water system.
We have a huge range of wood burners with back boilers from the leading manufacturers in the UK. We also have a huge range of boiler stove parts, pumps, thermal stores and spares for these models which means we can assist you with any inquiries.
Installation
There are many ways to connect a stove boiler to your central heating system. It can be connected to a combi boiler by using a special adaptor, or include a thermal store that allows the wood burning stove to supply your hot water system directly (this requires a separate cylinder in the loft to house the header tank). You can also give priority to hot water by connecting radiator loops and heat loss radiators through injector tees that connect to the stove and feeding the system from there. Another option is to use a thermopile thermostat to regulate the pump in the radiator loop so that the system will only run once the stove has heated the hot water tank and the heater has been shut off.
It is possible to connect a wood stove that has a back boiler to an existing heating system. It depends on the plumbing and system layout, but the majority of modern open vented systems can be connecting to a boiler stove little effort or expense. Before installing a multifuel back boiler it is best to consult an HETAS-certified person or plumber experienced with wet systems.
A typical system would comprise the thermal store with hot water storage tank, and a wood burning with a back boiler installed inside the firebox. The stove is connected to the system via one of back boiler water ports which are sized at 1 inch BSP (British Standard Pipe) and are easily converted to tubes of 22mm and 28mm with compression fittings that are available from the majority of reputable plumbing retailers.
The thermal store is a massive tank, it holds a considerable amount of heat. It is also connected to the radiators as well as the stove through a network of pipes and tees. The thermostatic switch controls the radiator loop which is only turned on the heating once the water temperature in the system has reached 55 degrees C.
A very popular option is the CSB
10kw multi fuel stove fuel wood burner with back boiler. This is a powerful stove that can power around 10 radiators throughout your house. It is able to burn logs as well as peat, coal, and smokeless fuel. The CSB can also be used as a supplementary heating source, such as a biomass pellet boiler or log gasifier.
