Mechanical Time Clock

worcester time clock

The Inbuilt Boiler Time Clock

The most basic of all controls, a simple easy to use time, clock often built into the boiler. This is a good starting point for a simple easy to use heating controls system. We would recommend adding a basic room stat and thermostatic radiator valves to your radiators and you will be in total control of your heating system. Unfortunately most modern boilers do not come with a basic time clock fitted as standard anymore, and are often ridiculously expensive for a clock that fits into the boiler as it has to be purchased from the boiler manufacturer. It is often more economical to fit a digital wireless programmable room stat if the boiler does not come with a built in time clock.

Worcester Mag

The Worcester Greenstar Filter System

Over time, central heating system water accumulates harmful dirt and debris, such as rust and solder fragments shed by radiators and boilers, all of which can cause considerable problems.
The Worcester Greenstar System Filter has been specifically designed to combat the damaging effects of system debris and pollutants by capturing contaminants before they reach your boiler.
Receive 1 extra year of boiler warranty when fitting this filter to your CDi boiler.

Adey Micro2

Adey Micro filter

The Adey Magnaclean Micro 2 

This magnetic filter from Adey is a little gem, its compact size allows it to be fitted in to the tightest of spaces and despite its compact size it is still capable of catching as much sludge as filters twice its size.
