Another stunning collection of designer heating from Milano, the Capri takes its name from the island off the coast of Italy and just like that little island, is the epitome of understated style.
A poisonous gas known as the silent killer, because you can’t see, smell or hear it. It is created from improperly burnt fuels like gas, coal and wood and causes around 50 deaths every year in the UK.
Not an essential part of a boiler working, the casing is the surround that protects the inner workings of the boiler.
This is a wall made of two separate and parallel masonry skins with a section of air space in between.
A minimalist designer radiator from Milano Heating, the Cayos is an instant style pick-me-up that combines designer styling with an impressive heat output.
A CE Marking is the declaration by any manufacturer that a particular product meets all appropriate European Directives. It shows that a product can be legally sold in the EU.
A common unit of temperature that has a zero point, which corresponds to the temperature at which water will freeze.
Centre to centre
Measuring from the centre line of one pipe to the centre line of another in order to make all of the tube centres appear uniform. This ensures that the pipework looks perfectly parallel.
The overall distance between the tappings on a radiator.
Radiators or towel rails that have their valve inlets at the bottom and the centre of the underside of the radiator. These are opposed to regular valve inlets, which are normally found at either side of the radiator.
Hot water is heated in a ‘central’ boiler and then circulated through the radiators in a building. There are two main types of radiator – single-pipe and double-pipe – the former working with steam and the latter with steam or water.
Central Heating Flow
This is the heated water leaving the boiler and the same water entering the radiators.
A sleek and contemporary designer radiator from heating specialists, Hudson Reed.
A groove that has been cut into masonry or plaster into which electrical cabling or pipework is fitted.
See Non-return valve.
Chrome/Chrome Plating/Chromium Plating
Chrome is applied in a thin layer to a surface to help prevent corrosion of the plated material and improve both appearance and maintenance.
Radiators require a certain amount of space underneath in order for them to adequately heat a room and operate correctly. The recommended (minimum) height (or clearance) from the base of the radiator to the floor is 150mm.
Closed Central Heating System
A central heating system that is closed off from the mains or external water supply. The majority of new heating systems are designed this way as it aids the prevention of water oxidisation.
Cold Water Storage Tank
Usually located in a loft, but can be found anywhere that is higher than the system – (see Feed & Expansion Tank)
Combination (Combi) Boiler
A boiler that supplies both instantaneous hot water and central heating from the same appliance.
A chemical reaction in which a substance (a fuel) reacts violently with oxygen to produce heat and light.
Air that provides the necessary amount of oxygen to ensure clean and complete combustion of a fuel, helping to maximise heating value.
Any space – wholly or partially enclosed – within which combustion takes place.
The reduction of volume of a vapour or a gas by mechanical means.
This is what your boiler can become if it gets to a point that renders it beyond repair – a heating engineer will normally be the one to make this decision.
This is what you may sometimes find on the inside of your windows at home or in your car. It occurs when water reaches its dew point – or condensation point – at which point air turns from vapour to a liquid due to changes in temperature and pressure.
A boiler that extracts all usable heat from the combustion process, cooling the flue gases – the collected water is then evacuated from the boiler form the condensate pipe.
Heat travelling through a substance with the heat being transferred from one molecule to another.
The property that enables a metal to carry heat (thermal conductivity) or electricity (electrical conductivity).
A type and style of interior decorating that contains the very latest style and trends, to help create an updated and modern look.
Heat transfer through the movement of a fluid substance – this could be water or air.
A radiator that transfers its heat via convection. These will normally have ‘fins’ at the back of the radiator or in between the radiators’ panels.
Any process involving the deterioration or degradation of metal components.
A chemical inhibitor that protects the inner workings of your heating system (See also Rust Inhibitor and Inhibitor).
There are two types of cylinders. A cylinder may be an ‘open vented’ type or an ‘unvented’ type. Vented cylinders have a vent pipe which will subject them to atmospheric pressure, whereas an unvented water cylinder is plumbed directly from the mains water supply. Unvented cylinders have many safety features in place to prevent excessive pressure build up and hot water expansion.
