Multifuel Stove With Back Boiler

A multifuel stove with a back boilers can be used to heat radiators and providing hot water to the home. This can reduce heating costs.

Adding a wood burning stove with a built in back boiler to an existing central heating system is relatively straightforward and can be done by a skilled plumbing engineer. This article explains how.

Features

When a stove is equipped with a boiler that heats up, the heat generated from burning wood or any other fuel is used to warm the water in a hot water cylinder and to warm the room. A boiler stove is capable of heating radiators throughout the house. If you are searching for a multifuel stove that has back boiler, there are a lot of options to choose from, all of which are covered by a full manufacturer's warranty.

A typical wood burner pumps heat in a single direction as it moves from the firebox to an outlet for the flue. A multifuel stove that has a back boiler will generate more energy as the heat is distributed across different directions in a more efficient way. This means more heat is directed to the room and less is lost through a flue outlet.

By putting a pipe in, you can transfer the heat produced by a multifuel woodburning fire place with the boiler to another room. This could lead to the heating of a hot water cylinder as well as radiators, or a non-pressurised shower. A thermostat is installed to monitor the temperature of the hot water tank. The radiators' pump will be activated when the level is reached. This prevents the hot water from running out and ensures the hot water cylinder has an ongoing supply of hot water available for domestic use.

The CSB multifuel stove with back boiler boasts an impressive output of 21 kw. It can be used to power a whole house via the central heating system, or a domestic hot water cylinder. The CSB is a versatile stove that can burn wood logs, anthracite, briquettes, and smokeless fuel. It can be used as an independent wood burner heated by the thermosyphon. The CSB is compatible with both closed and open system 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 multi-fuel stove and a boiler stove is that the latter has a built in water tank which 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, 8kW Multi Fuel Stove oil or electricity.

The main kind of multifuel stove that has a back boiler is the wraparound boiler stove, which has an water tank that runs along the sides and back of the firebox. The boiler part of the stove is positioned so that it hugs the firebox. This maximizes heating efficiency and power output. Wraparound boiler stoves are available from a range of top manufacturers like Stratford and Hunter Stoves.

The clip-in boiler stove is another option. It comes with a water tank which replaces the firebricks at the rear of the firebox. These stoves can't produce huge amounts of hot water because the boiler tank is smaller than the one of a wraparound stove.

You can put in a multifuel stove that has a back boiler in your system in several ways however the most popular way is to pipe it as a radiator into the vented heating system. This allows the boiler stove to be a second source of heating by turning on when your gas central heating turns on and boosting the temperature.

Installing a wood-burning fireplace with the boiler back is possible by connecting it to either a multi coil hot water tank or heat accumulator. In this case, your stove will heat the hot water tank prior to sending it to your radiators through an electronic thermostat. This setup is more complicated and should only by done by a certified heating technician.

If a multifuel stove that has a back burner is fitted improperly, it could be dangerous. This is because, when the stove is being used and the water inside the boiler turns into steam, which could cause the system to explode if not properly vented.

Fuel supply

The heat produced by the stove's combustion can be transferred to a water tank through a boiler unit that is built into the back. This lets you harness the heat and then use it within your home, multi fuel stove reducing energy costs and carbon footprints. This makes the stove more energy efficient since heat isn't lost up the chimney. This type of stove is often known as a wetback wood burning stove or a back boiler stove.

Modern multifuel stoves that are aesthetically appealing and feature back boilers that include a hot water cylinder that is pre-installed. You can connect the stove to the hot water system in your home to heat your taps as well as radiators. Certain older models of boiler stoves could have a separate hot water cylinder or they might have the boiler mounted into an adjustable box that could be fitted over the fire chamber.

This model features a huge firebox, with a large glass window and an "advanced air wash system" to ensure a clear view. This stove is also equipped with both top and bottom (Primary and Secondary) air vents to allow simple but effective control over the burn rate and heat output. The chrome door handle as well as 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 located at the rear. This increases the flow of air through the heat exchanger and increases the room temperature output and helps the stove achieve its maximum efficiency.

The models of the 'Elegance B' come with 4 water ports (2 flow and 2 x return) on the rear of the stove. These can be closed off when only one water heating circuit is required. These stoves will heat up to 10 average-sized radiators and the domestic hot water system if plumbed in correctly.

We offer a wide range of wood burning stoves with back boilers from the top UK manufacturers. We also have a wide range of parts for boiler stoves, pumps, thermal stores and spare parts for these models, which means we can assist you with any questions you might have.

Installation

There are a variety of ways to connect a stove boiler to your central heating system. You can connect it to a combi-boiler by using a specific adaptor or you can also add an energy storage unit that will allow your wood-burning stove to supply the hot water system on its own (this requires an additional header tank that is located in the loft). You can also give preference to hot water by connecting radiator loops and heat loss radiators via injector tees to the stove and feeding the system from there. A thermopile thermostat could be used to regulate the pump within the radiator loop. This will ensure that the system is running only after the stove has heated the hot water tank.

Incorporating a wood burner that has a back boiler to an existing system could be relatively simple. It is dependent on the plumbing system and layout but most modern open vented systems are capable of connecting a boiler stove with very little upheaval or expense. Before installing a multifuel back boiler it is best to consult an HETAS-certified person or a plumber who is familiar with wet systems.

A typical system will comprise a thermal store with hot water storage tank and a wood burner with a back boiler installed inside the firebox. The stove is connected to the system by way of the back boiler water ports that are sized at 1 inch BSP (British Standard Pipe) and can be easily modified to fit the size of 22mm or 28mm pipes by using compression fittings from reputable plumbing stores.

The thermal store is a large tank, it holds large quantities of heat. It is also connected to the radiators as well as the stove by a network of pipes and tees. The radiator loop is controlled by a thermostatic switch that only allows heating to be turned on when the hot water in the system has reached 55 degrees C.

A popular choice is the CSB multi fuel wood burner with back boiler. This is an extremely powerful stove which can power up to 10 radiators throughout your house. It can burn a wide range of fuels including coal, wood, peat and smokeless fuel. The CSB can also be used with an additional source of heat like a log gasifier or biomass pellet boiler.
