Multifuel Stove With Back Boiler
A multifuel stove (Keep Reading) that has a back boilers can heat radiators and also providing hot water to the house. This can 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 skilled plumbing engineer. This article explains how.
Features
When a stove is equipped with a boiler, the heat that is generated by burning wood or any other fuel is used to warm water in a hot water cylinder, and also to warm the room. A boiler stove can also provide heat to radiators in the home. We offer a wide selection of multifuel stoves with back boilers. All come with full manufacturer warranties.
A typical wood burner puts out energy in one direction as it flows from the firebox to a flue outlet. Multifuel stoves with a back boiler are more efficient because the heat is distributed across multiple directions more efficiently. This means that more heat is directed towards the room, and less heat is lost through the outlet of a flue.
Once the heat of a multifuel woodburning stove that has a back boiler is used to warm the space, it is possible for this heat to be transferred to other areas in the house through a pipe loop. This can result in the heating of the hot water cylinder, radiators or even a shower that is not pressurised. A thermostat is typically installed to monitor the temperature of the hot water tank and turn on the radiators’ pump when the temperature is at a certain point. This prevents the hot water from being depleted and ensures that the hot water cylinder has an ongoing supply of hot water available for domestic use.
The CSB multifuel stove that has a back boiler has an impressive output of 21, 000 watts. It can be used for the whole home via the central heating or even a household water cylinder. The CSB is a very versatile stove and will burn most types of wood logs and can also burn anthracite, coal, briquettes, and smokeless fuel. It can also be used as an independent wood burner heated by thermosyphon. The CSB works with open and closed system type central heating systems (not compatible with pressurised systems). A 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 that has a back boiler is that the latter features a built-in water tank that can be used 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 type of multifuel stove with back boiler is the wraparound stove, which is equipped with a water tank which runs across the sides and back of the firebox. This means that the boiler section of the stove effectively fits the firebox, thereby maximising heating efficiency 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 another option. It has a water tank that replaces the firebricks in the rear of the firebox. These stoves can’t produce huge amounts of hot water due to the fact that the boiler tank is smaller than a wraparound stove.
There are a variety of ways you can connect a multifuel stove with back boiler to your system, but the most common is by plumbing it as a radiator inside the vented central heating system. This allows the boiler stove to serve as an additional source of heat by turning on when the 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 either a Mazona Ripley: 8 kW Ecodesign Multi Fuel Stove – Buy Now! coil hot water tank or heat accumulator. In this scenario, your stove will heat the hot water tank before sending it to your radiators via an electronic thermostat. This is a more complex installation process and must be performed by a trained heating engineer.
A multifuel stove with a rear burner that’s not installed correctly can be dangerous. This is because, when the stove is being used the water in the boiler is converted into steam, which could cause the system to explode if it isn’t properly vented.
Fuel supply
The heat produced by the stove’s burning can be transferred to a tank of water via a boiler unit that is integrated into the back. This lets you make use of the heat and utilize it within your home, reducing energy costs and carbon footprints. 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.
Most modern aesthetically designed multifuel stoves that have a back boiler feature hot water cylinders that have the heating unit built into the body of the appliance. This allows you to connect the stove to your hot water system and make use of it to heat your radiators and taps around the house. Some older models of boiler stoves come with a separate hot-water cylinder, or the boiler may be placed in a movable box that can be positioned over the fire chamber.
This model features a large firebox with a large glass window made of ceramic that is complemented by an ” advanced air wash system’ to maintain an unobstructed view of flames. This large stove also incorporates both bottom and top (Primary and Secondary) air vents that allow simple but effective control over the heat and burn rate output. Its chrome door handle and air controls give a stylish appearance to the stove.
When the stove requires more air, a thermostatic probe connected to the stove will open and close a second vent in the rear. 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 return and 2 x flow) at the back of the stove. These can be shut off when only one circuit is required. 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 some of the top UK manufacturers. We also have a huge range of boiler stove parts such as thermal stores, pumps and spares for these models and we are able to assist with any questions you might have.
Installation
There are a variety of options for how a boiler stove could be connected to your central heating system. It is possible to connect it to a combi-boiler using a specific adaptor or you can also add a thermal storage to allow your wood burning stove to feed the hot water system on its own (this requires an additional header tank 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 through injector tees and feeding the hot water system via this. Another option is to use 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 turned off.
It is possible to add a wood stove with a back boiler to a heating system. It is dependent on the plumbing layout and system however, you can connect an electric boiler to modern open vented systems with little disruption or expense. Before installing a multifuel back boiler it is recommended to speak with an HETAS-certified person or a plumber who is familiar with wet systems.
A typical system will include a thermal store, an accumulator tank for hot water, and an electric woodburner with a back boiler 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 28mm or 22mm pipes using compression fittings.
The thermal store is a huge tank, it can hold a considerable amount of heat. It is connected to the radiators and the stove through a network of pipes and tees. The loop for the radiator is controlled by a thermostatic switch, which only allows heating to start once the hot water in the system has reached 55 deg C.
The CSB multi-fuel wood burner that comes with back boiler is a popular option. This is an extremely powerful stove that can provide power to up to 10 radiators in your home. It can burn logs, peat, coal and smokeless fuel. The CSB can also be used as a supplementary heat source like biomass or a log gasifier pellet boiler.
