Multifuel Stove With Back Boiler
A multifuel stove can heat radiators and provide hot water for the home. This could 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 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 other fuels is used to warm the water in a hot water cylinder, and also to warm a room. A boiler stove can warm radiators in your home. If you are searching for a multifuel stove that has back boiler, there are a lot of options to choose from, all of which come with a complete manufacturer’s warranty.
A typical wood burner puts heat in one direction as it moves through the outlet of a flue. Multifuel stoves with a back boiler generate more energy because the heat is distributed in multiple directions more efficiently. This means that more heat is directed to the room and less heat is lost through the outlet of a flue.
When the heat generated by a multifuel woodburning stove with a back boiler is used to warm the space, it is possible for the heat to be transferred elsewhere within the home by utilizing a pipe loop. This can be used to heat a hot water radiator, cylinder or even a non-pressurised shower. In most cases, a thermostat is installed to monitor the temperature of the hot water tank and switch on the radiators’ pumps when the temperature reaches. This stops the hot water from running out and ensures the hot water cylinder is able to provide a steady supply of hot water for domestic use.
The CSB multifuel stove with a back boiler boasts an impressive power output of 21kw. It can power a whole home via the central heating system or even a domestic hot water cylinder. The CSB is a highly versatile stove and will burn most types 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 can be used with open and closed system type central heating installations (not compatible with pressurised systems). The CSB is equipped with a stainless-steel thermal store or neutraliser.
Fuel type
The main difference between a standard multi fuel stoves fuel stove (go to the website) and a log burner with back boiler is that the latter comes with an integrated water tank that is able 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.
Wraparound boiler stoves are the most popular multifuel stoves that have back boilers. They are equipped with an water tank that runs across the sides and back of the firebox. This means that the boiler part of the stove effectively hugs the firebox, increasing the efficiency of heating and power output. Wraparound boiler stoves are available from a range of top manufacturers that include Stratford Stoves and Hunter Stoves.
Another alternative is the clip-in boiler stove, which has an water tank that replaces the firebricks located at the rear of the stove’s firebox. These stoves are not capable of producing large volumes of hot water because the boiler tank is smaller area than an all-round boiler stove.
There are several ways that you can connect multifuel stoves with back boiler to your system, but the most common is to use it as a radiator inside the vented central heating system. The boiler stove could be utilized as an additional source of heat by turning on when the gas central heating is on.
You can also install wood-burning stoves with a back boiler by connecting it to a multi fuel stoves uk-coil hot tank or an accumulator of heat. In this case, the stove will heat 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.
When a multifuel stove with a back burner is fitted incorrectly, it can be dangerous. When the stove is in use, the water in the boiler can turn into steam. This can cause the system to explode if it’s not properly vented to explode.
Fuel supply
The heat from the stove’s combustion is transferred to a tank of water through a boiler unit that is located in the back of the stove. This allows you to harness the heat and then use it to heat your home, reducing your energy bills and carbon footprints. This makes the stove more energy efficient because heat isn’t lost to the chimney. The system is generally known as a wetback wood burning stove, or a back boiler stove.
Modern multifuel stoves that are aesthetically appealing and feature back boilers come with a pre-installed hot water cylinder. The stove can be connected to the domestic hot water system to heat your faucets and radiators. Some older boiler stoves may come with a separate hot-water cylinder or the boiler installed in an adjustable box that could be placed to the top of the fire chamber.
This model comes with a massive firebox that has a large ceramic glass window that is complemented by an ” advanced air wash system” to keep an unobstructed view of flames. This large stove has both top and bottom air vents (Primary and Secondary) to permit easy but effective control of the burn rate and output. The chrome door handle and air control give the stove a an elegant appearance.
A thermostatic probe that is connected to the stove opens and closes an additonal vent at the rear of the stove when it needs extra air. This increases air flow through the heat exchanger, which boosts the output of room temperature.
The ‘Elegance B’ models have 4 water ports (2 flow and 2 x return) at 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 as well as the domestic hot water system, if installed correctly.
We offer a wide range of wood stoves with back boilers 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 a variety of options for how a stove for a boiler can be connected to your central heating system. It can be connected to a combi boiler by using a special adaptor or add a thermal store that allows the wood burning stove to feed your hot water system directly (this requires a separate cylinder inside the loft to serve as the header tank). It is also possible to prioritize the hot water by connecting the radiator loop and heat loss radiators to the stove through injector tees and feeding the hot water system from this. Another alternative is to use a thermopile thermostat to control the pump on the radiator loop so that the system will only run when the stove has heated up the hot water tank and the heater is shut off.
It is possible to add a wood stove with a back boiler to an existing heating system. It’s dependent on your plumbing layout and system, but you can connect an electric boiler to modern open vented systems with little disruption or expense. It is recommended to seek the advice of a HETAS certified person or a local plumber installer who is familiar with wet systems prior to installing a multifuel stove with back boiler.
A typical system would include a thermal store with an accumulator tank for hot water and a 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 large tank, it has the capacity to hold an enormous amount of heat. It is connected to the radiators and the stove by a network of pipes and tees. The loop for the radiator is controlled by a thermostatic switch that only allows heating to come on once the hot water in the system has reached 55 deg C.
The CSB multi fuel stove (go to the website)-fuel wood burner that comes with a back boiler is a popular choice. It is a powerful stove that can power up to 10 radiators in your home. It can burn wood, peat, coal and smokeless fuel. The CSB can also be used with an additional source of heat, like biomass or a log gasifier pellet boiler.
