multifuel stove with Back boiler (https://www.fireplacesandstove.com/products/warwick-4-kw-ecodesign-multi-fuel-stove)
A multifuel stove can heat radiators as well as provide hot water for your home. 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 straightforward and can be done by a qualified plumbing engineer. This article explains how.
Here are a few examples of
If a stove is equipped with an engine, the heat generated from burning wood or other fuel is used to heat hot water in a cylinder and to heat a space. A boiler stove can also heat radiators in the home. If you’re looking for a multifuel stove that has a back boiler then there are a lot of options to choose from, all of which are covered by a full manufacturer’s warranty.
A typical wood burner puts out energy in one direction as it moves from the firebox to an outlet for the flue. A multifuel stove with a back boiler will generate more energy since the heat is distributed across different directions in a more Efficient Warwick 4 kW Multi Fuel Stove manner. This means more heat is directed to the room and less heat is wasted through the outlet of a flue.
By putting a pipe in, you can transfer the heat created by a multifuel woodburning fire place with an electric boiler to a different room. This can be used to heat a hot-water cylinder, radiators, or even a nonpressurised shower. A thermostat is typically installed to keep track of the temperature of the hot water tank and turn on the radiators’ pump when this level is reached. This prevents the hot water from being depleted and ensures that the hot water cylinder is able to provide an ongoing supply of hot water available for domestic use.
The CSB multifuel stove with back boiler has an impressive power output of 21kw and can power a whole home via the central heating system or a domestic hot water cylinder. The CSB is a stove that can be used in a variety of ways that can burn wood logs, anthracite coal, brquettes, and smokeless fuel. Alternatively it can be run as a separate wood burner and heated using the thermosyphon system. The CSB works with closed and open system central heating systems (not compatible with pressurised systems). The CSB is equipped with a stainless-steel neutraliser or thermal store.
Fuel type
The distinction between a regular multi fuel stove and a log burner with back boiler is that the latter features a built-in water tank that is able to heat domestic hot water supplies and even radiators in your home. 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 popular kind of multifuel stove that has a back boiler is the wraparound stove, which features an water tank that runs along the sides and back of the firebox. This means that the boiler part of the stove effectively hugs the firebox, thereby maximising heating efficiency and power output. Wraparound boiler stoves are available from a range of top manufacturers such as Stratford Stoves and Hunter Stoves.
Another option is the clip-in boiler stove, which features an water tank that replaces the firebricks that are located at the rear of the stove’s firebox. These stoves are not able to produce large amounts of hot water because the boiler tank is smaller than the one of the wraparound stove.
You can install a multifuel stove with a back boiler in your system in a variety of ways but the most common way is to pipe it as a radiator into an air-ventilated heating system. The boiler stove can be used as an additional source of heat by turning on when the gas central heating is switched on.
You can also install an electric wood stove with a back boiler by connecting it to a multi-coil hot water tank or a heat accumulator. In this case the stove will heat up the hot water tank, and then send it to your radiators using the thermostatic control valve. This is a more complicated installation and should only be carried out by a qualified heating technician.
When a multifuel stove with a back burner is installed improperly, it could be dangerous. This is because when the stove is being used the water in the boiler transforms into steam, which can cause the system to explode if not correctly vented.
Fuel supply
The heat produced by the stove’s combustion could be transferred to a water tank through a boiler unit that is integrated into the back. You can use the heat inside your home to cut down on carbon emissions and energy costs. It also makes the stove more efficient because it prevents heat escaping up the chimney. The system is generally known as a wetback wood burning stove, or a back boiler stove.
Modern multifuel stoves that are aesthetically attractive and come with back boilers that include a hot water cylinder that is pre-installed. The stove can be connected to the hot water system in your home to heat your taps as well as radiators. Certain older models of boiler stoves might have a separate hot water cylinder or they might have the boiler installed in an adjustable box that could be placed on top of the fire chamber.
This model features a huge firebox, a large ceramic window and an “advanced air wash system” to ensure an unobstructed view. This large stove also incorporates both the top and bottom (Primary and Secondary) air vents to allow simple but effective control over the burn rate and heat output. The chrome door handle and air control give the stove a an elegant appearance.
A thermostatic probe that is connected to the stove’s thermostat opens and closes an additonal vent on the rear of the stove whenever it needs additional air. This increases air flow through the heat exchanger, which boosts the output of a room temperature.
The ‘Elegance B” models come with four water ports (2 x return and 2 flow) on the back of the stove. These can be shut off when only one circuit is required. These stoves will heat up to 10 average sized radiators and the domestic hot water system is properly plumbed in.
We offer a wide range of wood burners that come with back boilers that are available from the top manufacturers in the UK. We also have a wide range of parts for boiler stoves such as pumps, thermal stores and spares for these models which means we can assist you with all of your enquiries.
Installation
There are many options on how a boiler stove can be connected to your central heating system. It is possible to connect it to a combi-boiler by using a specific 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 a separate header tank that is located in the loft). It is also possible to make it priority for the hot water by connecting the radiator loop and heat loss radiators to the boiler stove using injector tees, and feeding the hot water system via this. Another alternative is to utilize a thermopile thermostat to regulate the pump on the radiator loop so that the system is only running after the stove has heated up the hot water tank and the heater is switched off.
Adding a wood burner with back boiler to an existing system could be quite simple. It depends on the plumbing and system layout but most modern open vented systems can be connecting to a boiler stove little effort or expense. It is recommended to seek the advice of a HETAS qualified person or a local plumber installer who is familiar with wet systems before installing a multifuel stove that has a back boiler.
A typical system would comprise a thermal store with an accumulator tank for hot water and woodburners with a back boiler installed in the firebox. The back boiler water ports are used to connect the stove to the system. These ports are 1 inch BSP and can be easily adapted to the size of 22mm or 28mm pipes using compression fittings.
The thermal store is a huge tank that holds a considerable amount of heat. It is also connected to the radiators as well as the stove by a network of pipes and tees. The loop of radiators is controlled by a thermostatic switch which only allows heating to be turned on when the temperature of the hot water within the system has reached 55 degrees C.
A popular option is the CSB multi fuel wood burner with back boiler, this is a very powerful stove that can power about 10 radiators throughout your home. It can burn a wide range of fuels including logs, coal, peat and smokeless fuel. The CSB can also be used as a supplementary heating source, like biomass pellet boiler or log gasifier.
