  • Worcester DT20 Twin Channel Digital Programmer

    The Worcester DT20 Twin Channel Digital Programmer allows the user to set 3 different central heating and hot water times each day and can be different times for each day of the week. The DT20 will automatically set to the right time and can also adjust the time to the Greenwich mean time and british summer time so that the does not have to worry about making the changes themselves. The DT20 also features the innovative holiday function whereby normal central hearting and hot water times can be suspended while the owners are away and resume upon their return.

    The Worcester DT20 Twin Channel Digital Programmer is compatible with all Greenstar Combi Boiler ranges and with Greenstar System Boilers as long as the optional intergrated diverter valve is also used. The DT20 can also be used with the FR10 intelligent room thermostat and will help increase the boilers fuel efficiency and reducing fuel bills and carbon emissions. 

    At Boilers2go we recommend the DT20 for use with Worcester Greenstar Combi Boilers for greater control over central heating and hot water times compared with a standard programmer and its ability to help reduce fuel consumption when used with the FR10 room stat.

  • Fernox TF1 total filter 22 mm

    The Fernox TF1 Total Filter is a revolutionary in-line filter that combines hydrocyclonic action with specially designed magnetic assemblies to remove both magnetic and non-magnetic debris and contaminants commonly found in central heating systems. Commonly found debris within central heating systems include iron oxide sludge, scale, casting sand, welding debris and non ferrous metal flakes which can cause the premature failure of valves and pumps and cause blockages with heat exchangers, pipework and radiators. Such problems can be costly to remedy and blockages can cause cold spots in radiators and significantly reduce the efficiency of the boiler and central heating system. A reduction in energy efficiency can result in higher fuel bills and carbon emissions which is bad news for households making a boiler filter such as the TF1 Total Filter a wise investment.

    Key Features & Benefits:

    • Hydrocyclonic and magnetic filters for effective filtration
    • Removes both magnetic and non-magnetic debris
    • Fits both vertically and horizontally
    • Cleaned quickly and simply without removal or disassembly
    • Will not restrict flow
    • Valves and Fittings included


    At Boilers2go we highly recommend the Fernox TF1 Total Filter 22m for systems using 22mm pipe and to fully protect the central heating system for commonly occurring contaminants. Also the TF1 Total Filter 22mm will ensure the optimum running efficiency of the boiler and central heating system resulting in continued reduced fuel bills and carbon emissions.
