Multifuel Stove With Back Boiler

A multifuel stove with a back boiler can heat radiators as well as heating hot water for the property. This could reduce heating costs.

The addition of a wood-burning stove with a built in back boiler to an existing central heating system is simple and can be accomplished by a qualified plumbing engineer. This article explains how.

Here are some examples of

When a stove has 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 capable of heating radiators throughout the home. We have a broad selection of multifuel stoves with back boilers. All are covered by the manufacturer's warranty.

A typical wood burner pumps out energy as heat in one direction when it moves from the firebox through an outlet for the flue. Multifuel stoves that have a back boiler produce more energy because the heat is distributed across multiple directions more efficiently. This means that more heat is directed to the room, and less heat is lost through an outlet for the flue.

When the heat generated by a multifuel woodburning stove with a back boiler is used to heat the room, it is possible for this heat to be transferred elsewhere within the home by utilizing a pipe loop. This can lead to the heating of a hot water cylinder as well as radiators, or a non-pressurised shower. Typically a thermostat would be installed to keep track of the temperature of the hot water tank and switch on the pump for the radiators when the temperature reaches. This will stop the hot water cylinder from leaking, and will ensure that there is a constant supply of hot water for domestic use.

The CSB multifuel stove that comes with a back boiler boasts an impressive power output of 21kw and can be used to power a whole home via the central heating system, or a domestic hot water cylinder. The CSB is a multi-purpose stove that can burn wood logs, anthracite, briquettes, and 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 system type central heating installations (not compatible with pressurised systems). The CSB comes 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 a built in water tank which can 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.

Wraparound boiler stoves are the most common multifuel stoves that have back boilers. They feature 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, increasing heating efficiency and power output. Wraparound boiler stoves arel stoves that have a back boiler feature hot water cylinders with the heating unit pre-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 boiler stoves might include a separate hot water cylinder or the boiler mounted into an adjustable box that could be positioned on top of the fire chamber.

This model has a large firebox, an enormous ceramic window as well as an "advanced air wash system" to ensure a clear view. This large stove has both top and bottom air vents (Primary and Secondary) to permit easy but effective control of the burning rate and output. The chrome door handle as well as air controls add a chic appearance to the stove.

If the stove requires more air the thermostatic probe that is attached to the stove will open and close a second vent at the rear. This improves air flow through the heat exchanger which increases the output of room temperature.

The 'Elegance B' models have 4 water ports (2 x flow and 2 x return) located on the rear of the stove. These can be closed off when only one water heating circuit is required. If properly plumbed, these stoves can heat up to 10 radiators in average size as well as the domestic hot-water system.

We have a variety of wood burning stoves, including back boilers from the top UK manufacturers. We also have a huge selection of parts for boiler stoves such as thermal stores, pumps and spares for these models so we can help you with any questions you might have.

Installation

There are a myriad of options for how a stove for a boiler can be connected to your central heating system. You can link it to a combi boiler using a special adaptor or add a thermal store that allows the wood burning stove to supply your hot water system by itself (this requires a separate cylinder in the loft to serve as the header tank). It is also possible to make it priority for 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 alternative is to use a thermopile thermostat to control the pump on the radiator loop, so that the system only runs once the stove has heated up the hot water tank and the heater has been switched off.

Adding a wood burner with back boiler to an existing system could be fairly simple. It is dependent on the plumbing and system layout, but modern open vented systems are capable of connecting a boiler stove with 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 will include a thermal store, an accumulator tank for hot water and a woodburner 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 easily be adapted to the size of 22mm or 28mm pipes using compression fittings.

The thermal store is a huge tank, it has the capacity to hold a considerable amount of heat. It is connected to the radiators and the stove by a network of pipes and tees. The thermostatic switch controls the radiator loop, which only turns on the heating when the water temperature in the system reaches 55 degrees C.

The CSB small multi fuel stove-fuel wood burner that comes with back boiler is a popular choice. It is a powerful stove that can run up to 10 radiators within your home. It is able to burn logs as well as peat, coal, and smokeless fuel. The CSB is also compatible with additional heating sources, such as a biomass pellet boiler or log gasifier.
