Multifuel Stove With Back Boiler

A multifuel stove can heat radiators and supply hot water for the home. This can reduce heating costs.

Installing 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 the process.

Features

When a stove is fitted with a boiler, the heat that is produced by burning wood or other fuels is used to warm the water in a hot water cylinder, and also to heat rooms. A boiler stove can provide heat to radiators in the home. If you're looking for a multifuel stove with a back boiler then there are a lot of options to pick from, and all of them come with full manufacturers warranties.

A typical wood burner pumps out energy in a single direction as it moves from the firebox through an outlet for the flue. A multifuel stove with a back boiler will generate more energy because the heat is distributed over different directions in a more efficient way. This means more heat is directed to the room and less heat is wasted down the outlet of the flue.

By putting a pipe in, you can transfer the heat generated by a multifuel woodburning fireplace that has a boiler to another room. This could be used to heat a hot-water cylinder, radiators or even a nonpressurised shower. A thermostat is installed to monitor the temperature inside the hot water tank. The radiators' pumps will be activated once the desired temperature is reached. This prevents the hot water from running out and ensures that the hot water cylinder is able to provide an ongoing supply of hot water for domestic use.

The CSB multifuel with a back-boiler has an impressive output of 21, 000 watts. It can be used to heat a whole home via the central heating system, or even a water cylinder for the domestic. The CSB is a highly versatile stove that burns all kinds of wood logs and can also burn anthracite, coal, briquettes, and smokeless fuel. It can be used as a stand-alone wood burner heated by thermosyphon. The CSB is compatible with both closed and open central heating systems (not compatible with pressured systems). A CSB comes with a stainless-steel thermal store or neutraliser.

Fuel type

The distinction between a regular multi fuel stove and a log burner that has a back boiler is that the latter has an inbuilt water tank that can be used to heat domestic hot water sources 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 boiler stove, which has a water tank which runs through the sides and the back of the firebox. This means that the boiler section of the stove is able to effectively hug the firebox, increasing heating efficiency and power output. Wraparound boiler stoves are available from a variety of top manufacturers like Stratford and Hunter Stoves.

The clip-in boiler stove is a different option. It comes with an water tank that replaces the firebricks that are located in the rear of the firebox. These types of stoves aren't capable of producing large quantities of hot water because the boiler tank is smaller surface area than an all-round boiler stove.

You can put in a multifuel stove with back boilers in your system in several ways, but the most common way is to pipe it as a radiator into an air-ventilated heating system. This allows the boiler stove to act as an additional source of heat by turning on when your gas central heating turns on and boosting the temperature.

You can also install an electric wood stove with a back boiler by connecting it to a multi fuel stoves with back boiler-coil hot water tank or a heat accumulator. In this case, the stove will heat the hot water tank before sending it to your radiators using an electronic thermostat. This is a more difficult installation procedure and should only be carried out by a trained heating engineer.

A multifuel stove with a rear burner that's not installed correctly could be dangerous. When the stove is in use, the water in the boiler can transform into steam. This could cause damage to the system if it's not correctly vented to explode.

Fuel supply

The heat generated by the stove's burning can be transferred to a water tank via a boiler that is that is integrated into the back. You can utilize the heat in your home to cut down on carbon emissions and energy costs. It also makes the stove more efficient because it stops heat from going up the chimney. This system is usually referred to as a wetback wood burning stove, or a back boiler stove.

Modern, attractive multifuel stoves that have a back boiler have hot water cylinders 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 taps and radiators. Some older model boiler stoves could include a separate hot water cylinder or the boiler tucked away in a removable box that can be fitted on top of the fire chamber.

This model has a huge 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 stove is large and has top and bottom air vents (Primary & Secondary) to allow for simple, but efficient control of the burn rate and output. The chrome door handle and air control give the stove an elegant appearance.

When the stove requires more air the thermostatic probe that is attached to the stove will open and close an additional vent in the rear. This boosts the flow of air through the heat exchanger, which boosts the output of room temperature.

The models of the 'Elegance B' have four water ports (2 flow and 2 return) at the rear of the stove. These can be closed off when only one water heating circuit is required. The stoves can heat up to 10 standard radiators and the domestic hot water system is plumbed in correctly.

We have a huge range of wood stoves with back boilers that are available from the top manufacturers in the UK. We also have a broad range of boiler stoves, thermal stores and pumps for these models.

Installation

There are several ways to connect a boiler stove to your central heating system. It can be connected to a combi-boiler using a special adaptor or you can install a thermal storage to 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 option is to use a thermopile thermostat to control the pump in the radiator loop to ensure that the system will only run when the stove has heated up the hot water tank and the heater has been turned off.

Incorporating a wood burner that has a back boiler to an existing system could be fairly easy. It is dependent on the plumbing and system layout, but the majority of modern open vented systems are capable of connecting to a boiler stove little effort or expense. Before installing a multifuel back boiler it is recommended to speak with a HETAS-qualified person or a plumber who is familiar with wet systems.

A typical system would comprise a thermal store and an accumulator tank to store 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 easily be adapted to 28mm or 22mm pipes using compression fittings.

The thermal store is a huge tank that can hold a lot of heat. It is connected to the stove and radiators via a system of pipes and tees. The loop of radiators is controlled by a thermostatic switch, which only allows heating to come on once the temperature of the hot water in the system is at 55 degrees C.

A popular choice is the CSB multi fuel wood burning stoves fuel wood burner with back boiler. This is an extremely powerful stove which can power around 10 radiators throughout your house. It can burn a diverse variety of fuels, including coal, wood peat, smokeless fuel and peat. The CSB can also be used as additional heating sources, like a biomass pellet boiler or log gasifier.
