Multifuel Stove With Back Boiler

A multifuel stove with back boilers can be used to heat radiators and 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 competent plumbing engineer. This article explains how.

Features

When a stove is fitted with a boiler, the heat that is produced by burning wood or other fuel is used to warm water in a hot water cylinder and to heat rooms. A boiler stove is able to heat radiators throughout the house. We have a large selection of multifuel stoves with back boilers. All come with full manufacturer warranties.

A standard wood stove produces heat in one direction as it passes through the flue outlet that is located inside the firebox. A multifuel stove that has back boilers will produce more energy since the heat is distributed over multiple directions in a more efficient way. This means that more heat is directed into the room, and less heat is wasted through an outlet for the flue.

Once the heat from a multifuel woodburning stove that has a back boiler is used to warm the space, it is possible for this heat to be transferred elsewhere within the home through a pipe loop. This could be used to heat a hot water cylinder, radiators or even a non-pressurised shower. A thermostat is installed to monitor the temperature of the hot water tank. The radiators' pumps will be activated when the level is reached. This will stop the hot water tank from running out and will ensure a constant supply of hot water for domestic use.

The CSB multifuel stove with a back-boiler boasts an impressive output of 21, 000 watts and can be used to heat a entire home with the help of central heating system or even a household water cylinder. The CSB is a versatile stove that can burn wood logs, anthracite coal Briquettes, as well as smokeless fuel. It can also be operated as a standalone wood burner, and heated by the thermosyphon system. The CSB works with open and closed system type central heating installations (not compatible with pressurised systems). A CSB is usually supplied with an 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 comes with an integrated water tank that can heat your home's domestic 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 well-known kind of multifuel stoves that come with back boilers. They are equipped with an water tank that runs along the sides and back of the firebox. This means that the boiler portion of the stove is able to effectively hug the firebox, thereby maximising the efficiency of heating and power output. Wraparound boiler stoves are available from a range of leading manufacturers including Stratford and Hunter Stoves.

Another option is the clip-in stove, which has a water tank which replaces the firebricks located at the rear of the stove's firebox. These stoves are not capable of producing large quantities of hot water, since the boiler tank has a much smaller surface area than a wraparound boiler stove.

There are a variety of ways you can fit multifuel stoves with a back boiler to your system However, the most common is by plumbing it as a radiator inside the central heating system that is vented. The boiler stove can be used as an additional source of heating by turning it on when the gas central heating is on.

Installing a wood-burning stove with the boiler back is possible by connecting it to either a cheap multi fuel stoves coil hot water tank or heat accumulator. In this case, the stove will warm the hot water tank, and then deliver it to your radiators via a thermostatic control valve. This is a more difficult installation process and should only be done by a qualified heating engineer.

A multifuel stove with a rear burner that's not installed correctly could be dangerous. This is because when the stove is being used, the water inside the boiler turns into steam, which can cause the system to explode if it isn't properly vented.

Fuel supply

The heat produced by the stove's combustion can be transferred to a tank of water via a boiler that is integrated into the back. This lets you harness the heat and use it within your home, reducing energy costs and carbon footprints. This makes the stove more energy efficient, as heat is not lost through the chimney. This type of stove is also referred to as a back boiler or a wetback stove.

Modern multifuel stoves that have a back boiler feature a hot water cylinder with the heating unit already built into the body of the appliance. You can connect the stove to the hot water system in your home to heat your faucets and radiators. Certain older models of boiler stoves have an additional hot-water cylinder or the boiler could be mounted in a removable box that can be placed on top of the fire chamber.

This model has a large firebox, with an enormous ceramic window as well as an "advanced air wash system" to maintain a clear view. This stove is large and has the top and bottom air vents (Primary & Secondary) to allow for simple, but efficient control of the burn rate and output. Its chrome door handle and air controls provide a fashionable appearance to the stove.

When the stove needs more air, a thermostatic probe attached to the stove will open and close an additional vent located at the rear. This improves air flow through the heat exchanger which increases 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 closed off when only one circuit is needed. If plumbed correctly the stoves can heat up to 10 radiators of average size and the hot-water system for domestic use.

We offer a broad selection of wood burning stoves, including back boilers from the UK's top manufacturers. We also stock a large selection of boiler stove parts such as pumps, thermal stores and spares for these models, so we can help you with all of your enquiries.

Installation

There are many ways to connect a boiler stove to your central heating system. You can connect it to a combi boiler by using a special adaptor or include a thermal store that will allow the wood-burning stove to supply your hot water system on its own (this requires an additional cylinder in the loft to serve as the header tank). You can also give priority to hot water by connecting loops of radiators and heat loss radiators using injector tees to the stove and feeding the system from there. A thermopile thermostat can be used to regulate the pump within the radiator loop. This will ensure that the system runs only after the stove has heated the hot water tank.

It is possible to connect an existing wood stove with a back boiler to an existing heating system. It is dependent on the system and plumbing layout, but the majority of modern open vented systems can be connecting a boiler stove with little effort or expense. Before installing a 5kw defra multifuel stove back boiler it is recommended to speak with a HETAS-qualified person or a plumber familiar with wet systems.

A typical system would include a thermal store with 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 massive tank that has the capacity to hold large quantities of heat and is connected to the radiators as well as the stove via a system of pipes and tees. The thermostatic switch regulates the radiator loop, which only turns on the heating once the temperature of the water in the system is 55 degrees C.

A popular choice is the CSB multi fuel wood burner with back boiler. This is a very powerful stove which can power about 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, like biomass pellet boiler or log gasifier.
