Multifuel Stove With Back Boiler
A multifuel stove with back boiler can be used to heat radiators and supplying hot water to the home. This could lower heating costs.
The addition of a wood-burning stove with a built-in back boiler to an existing central heating system is easy and can be completed by a skilled plumbing engineer. This article explains how.
Features
When a stove is fitted with a boiler that heats up, the heat produced by burning wood or other fuel is used to warm water in a hot water cylinder as well as to warm rooms. A boiler stove is also capable of heating radiators throughout the house. We have a broad selection of multifuel stoves with back boilers. All come with full manufacturer warranties.
A typical wood burner pumps out energy in one direction when it moves from the firebox to an outlet for the flue. Multifuel stoves with back boiler are more efficient because the heat is distributed in multiple directions more efficiently. This means that more heat is directed into the room, and less heat is wasted through the outlet of a flue.
When the heat generated by a multifuel woodburning fireplace with a back boiler is used to heat a room it is then possible for this heat to be transferred elsewhere in the house through the pipe loop. This can be used to heat a hot water radiator, cylinder or even a non-pressurised shower. A thermostat is installed to monitor the temperature in the hot water tank. The radiators' pumps will be activated once the desired temperature is attained. This prevents the hot water from being depleted and ensures that the hot water cylinder is able to provide an uninterrupted supply of hot water available for domestic use.
The CSB multifuel stove with a back boiler boasts an impressive power output of 21kw and can power a complete home using the central heating system or even 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, briquettes, and smokeless fuel. Additionally, it can be used as a standalone wood burner, and heated by thermosyphon technology. The CSB works with closed and open system central heating installations (not compatible with pressurised systems). The CSB is equipped with a stainless-steel neutraliser or thermal store.
Fuel type
The difference between a normal multi fuel stove and a log burner that has a back boiler is that the latter features an integrated water tank that can be used to heat domestic hot water supply and even radiators within 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 boiler stove, which is equipped with a water tank that runs along the sides and back of the firebox. The boiler portion of the stove is set so that it hugs the firebox. This increases the efficiency of heating and power output. Wraparound boiler stoves can be found from a number of leading manufacturers such as Stratford Stoves and Hunter Stoves.
The clip-in boiler stove is another option. It comes with a water tank that replaces the firebricks at the rear of the firebox. These types of stoves aren't capable of producing large volumes of hot water because the boiler tank is much smaller surface area than a wraparound boiler stove.
It is possible to install a multifuel stove with an back boiler within your system in a variety of ways, but the most common way is to pipe it as an air-tight radiator into a vented heating system. The boiler stove can then be used as an additional source of heat by turning on when the gas central heating is switched on.
Installing a wood-burning stove that has a boiler back is also possible by connecting it to either 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 a thermostatic valve. This is a more difficult installation procedure that should only be carried out by a trained heating engineer.
A multifuel stove with a rear burner that is not installed correctly could be dangerous. When the stove is used, the water in the boiler can turn into steam. This can cause the system if it's not correctly vented to explode.
Fuel supply
The heat from the stove's combustion is transferred to a tank of water through a boiler unit that is built into the back of the stove. You can utilize the heat from your home to lower carbon emissions and energy bills. It also makes the stove more efficient because it prevents heat escaping up the chimney. This type of stove is also referred to as back boilers or wetback stove.
Modern, attractive multifuel stoves with a back boiler include hot water cylinders with the heating unit already built into the body of the appliance. The stove can be connected to the domestic hot water system to heat your taps as well as radiators. Some older boiler stoves might have a separate hot water cylinder or the boiler mounted into an open box that can be placed over the fire chamber.
This model features a large firebox with a huge ceramic glass window that is complemented by an " advanced air wash system" to ensure a clear view of the flames. This large stove has both top and bottom air vents (Primary & Secondary) to permit simple but effective control of the burn rate and output. Its chrome door handle and air controls give a stylish appearance to the stove.
A thermostatic probe linked to the stove opens and closes an additional vent located at the back of the stove whenever it needs additional air. This boosts the flow of air through the heat exchanger which increases the output of a room temperature.
The "Elegance B" models have four water ports (2 return and 2 x flow) on the back of the stove. They can be shut off when only one circuit is needed. If properly plumbed the stoves can heat up to 10 radiators in average size, as well as the domestic hot-water system.
We offer a broad selection of wood burning stoves with back boilers from some of the top UK manufacturers. We also have a huge range of parts for boiler stoves, thermal stores, pumps and spare parts for these models, and we are able to assist with any inquiries.
Installation
There are many ways to connect a boiler stove to your central heating system. It can be connected to a combi boiler using a specific adaptor or add a thermal store that allows the wood-burning stove to supply your hot water system by itself (this requires an additional cylinder in the loft to serve as the header tank). It is also possible to give priority to the hot water by connecting the radiator loop and heat loss radiators to the stove using injector tees, and feeding the hot water system via this. Another option is to use a thermopile thermostat to control the pump in the radiator loop, so that the system is only running once the stove has heated up the hot water tank and the heater is turned off.
The addition of a wood burner with back boiler to an existing system can be quite simple. 10kw multi fuel stove on the plumbing system and layout, but the majority of modern open vented systems are capable of connecting to a boiler stove minimal disruption or expense. Before installing a multifuel back boiler, it is best to consult an HETAS-certified professional, a plumber or installer familiar with wet systems.
A typical system will comprise a thermal store and hot water accumulator tank and a wood burner with a back boiler installed inside the firebox. The stove is connected to the system via one of back boiler water ports which are designed to be 1 inch in size BSP (British Standard Pipe) and can be easily converted to the size of 22mm or 28mm pipes by with compression fittings that are available from the majority of reputable plumbing retailers.
The thermal store is a massive tank that can hold a lot of heat. It is connected to the stove and radiators by pipes and tees. The thermostatic switch regulates the radiator loop that only activates the heating once the water temperature in the system is 55 degrees C.
A popular option is the CSB multi fuel wood burner with back boiler, this is a very robust stove that can power up to 10 radiators in your home. It can burn a wide variety of fuels, including coal, wood, peat and smokeless fuel. The CSB can also be used as a supplementary heating source, such as biomass pellet boilers or log gasifier.
