The Thermomatic Combi, The Complete Combination

When choosing a Thermomatic Boiler, you are choosing a quality product, which due to its unique design will give years of satisfactory service. Other combination boilers are usually "dry wall" boilers. These are insulated around the combustion (burner) area to prevent excessive heat ‘build up’ to the metal sides.

The Thermomatic Combi boiler has a water Jacket extending to the burner assembly. Heat radiating from the burner is absorbed into the water. This gives a higher boiler efficiency and reduces the running cost.

Other Advantages:

• No cold water or other storage tanks to freeze or leak.
• The Thermomatic is a complete combi boiler which includes several expensive items normally purchased by the installer and fitted separately. These parts are correctly matched, tested, and guaranteed with the boiler.
• The Thermomatic is simple to operate. It is fully automatic. Just switch on and your boiler will light.
• Simply switch to Summer use when hot water only is needed, and to Winter use for both central heating and hot water.
• With a Thermomatic combination boiler, you can never run out of hot water.

Completely Safe

By choosing a Thermomatic boiler, you will choose not only the most reliable boiler, it will be guaranteed by Keston Boilers.

Economical

100 hot baths or several hundred showers is the price paid for one year's unnecessary pilot flame.

All Thermomatic room sealed boilers have automatic ignition which eliminates the pilot burner, saving a full 60m3. (2100 cu. ft.) gas per year.

The circulating pump on the central heating operates from a capillary thermostat, and does not switch on until the water reaches 60°C and switches off below this temperature.
The domestic hot water does not need a pump.
All this plus a high efficiency boiler gives a very positive saving in fuel consumption.

Easy to Operate

Just switch on, the boiler is full automatic.

Versatile

Switch on to Summer use for hot water only.
Switch to Winter use for central heating and hot water.

Durable

The materials used, and boiler controls for this boiler ensures reliability for many years to come.

Advantages to the Installer

• A ‘Filling Loop’ complete with double check valves and separate "shut off " valve is a Water Board requirement when fitting combination boilers. The Thermomatic has these supplied as standard. This saves the additional cost involved in purchasing these as additional items.
  Often combi boilers are supplied without a pressure vessel on the domestic hot water line. This would add a further cost to comply with Water Board regulations. The Thermomatic fits a separate hot water mini expansion vessel as standard.
• The pipework connection manifold is detachable from the rest of the boiler. Hence, using the supplied template, all pipework connections can be made and fixed to the wall without the boiler in position. The boiler itself can be wall hung and quickly connected to the manifold at the very last stage of installation.
• A Flow Regulating valve is also fitted to the boiler, allowing the installer to regulate the flow of water through the hot water taps.
• Flow and return ball valves, domestic and gas valves are already fitted to the boiler connection plate.
• Room sealed boilers arrive with a 90° flue bend and one metre of flue assembly pipe. Extension kits are available to give up to 3m horizontally or vertically.
• Thermostatic radiator valves may be fitted on all radiators without affecting the boiler.
• A by-pass is not needed on the boiler or the external pipework.
• Easily dismountable boiler casing makes servicing simple.
• All parts are easily obtainable in the UK.

Technical Data

REMEMBER

The Thermomatic is the least complicated of all the combination boilers. With less complications, there are less "call backs".
