The Stratford TF90 coal and wood burning multi-fuel boiler stove , the largest of the Stratford family of boiler multi-fuel stoves made by Aarrow, it offers a mighty 28.5kW output and the capability to provide domestic hot water and heat up to 19 radiators. It really is the complete home heating solution. Stratford multi-fuel boilers are a market leading brand well known and respected for their performance, quality design and craftmanship. Each Stratford multi-fuel boiler stove can be fuelled on either coal or wood and is easily optimised (by flicking a lever) to burn either fuel in its preferred conditions to maximise efficiency and increased control. Features include; anti-cold water corrosion system, primary air diversion grate, airwash system, thermostatic control and extra thick steel boiler.
Smart Technology from Aarrow
Primary Air Diversion grate
The air diversion grate allows the flow of air to come up through the grate for coal or to come in over the top of the grate for wood to ensure each fuel burns in its ideal conditions. The control for this system is clearly marked on the side of the stove and can quickly and easily be set for either coal or wood.
Airwash
Aarrows airwash system uses a curtain of preheated air to protect the glass from darkening with unburnt material ensuring you always have crystal clear view of your fire.
The following advice is designed to answer some of the more commonly asked questions and give guidance on getting the best out of a Stratford stove.
1.
Contact your local Heating Engineer prior to ordering find one here : www.hetas.co.uk , ask them to calculate the BTU/kW requirements of your system, it is important to match the BTU/kW output of the boiler to that required by your system. The number of radiators in average installation given here is for guidance only, and should not be used alone for choosing the right size stove.
2.
Stratford boiler stoves should only be installed in an indirect system.
3.
A flue draw measurement should be taken at the time of installation and overdrawing flues should have measures taken to reduce their draw. Uncorrected, an overdrawing flue may mean that the stove is unable to shut down and slumber once installed, this can cause over firing and may damage the appliance.
4.
A heat leak radiator should be installed that is 10% of the rated output of the boiler.
5.
A radiator may be required in the room where the boiler is installed as the radiated heat outputs of boiler models are fairly small due to the efficiency of the boiler.
6.
A pipe stat must be fitted to the return hot water, set at 45°C.
7.
A rust inhibitor should be added to the heating once the engineer is happy there are no leaks from the system.
8.
If using solid fuel ensure only recommended fuels are used, and definitely no Petroleum Based fuels. Please refer to your installation manual for further information.
9.
If burning wood use only seasoned, dry wood. Unseasoned and wet wood will burn inefficiently and can damage flue and stove. For every twelve hours alight a period of fast burn should be undertaken for up to 20 minutes to ensure the flue is cleared.
Please note that numbers of radiators quoted are based on an average size single radiator, and that in order to match a stove to your home's energy requirement, both Gr8 fires and Arada strongly recommend consulting a heating engineer to calculate your requirements.
