Conventional Boilers

Conventional boilers are generally used in conjunction with a hot water cylinder and roof tanks and radiators. Available for oil or gas, floor standing or wall mounted with a large range of flueing options. External oil fired conventional boilers are also available.

Megaflow system- delivering more hot water

A mains pressure system takes water directly from the mains and supplies it to both the hot and cold systems. For the hot water, the mains is supplied direct to the boiler. The heated water is then stored in a special hot water storage cylinder built to withstand the pressures of mains hot water. These systems were only introduced into the UK relatively recently and is used when a standard system is not covering the needs of the property.

Condensing Boilers

By converting approximately 88% of fuel into heat compared to 72%+ for a new conventional boiler, the condensing boiler is the most efficient of them all, wasting the least energy. Condensing boilers are available as both conventional or combination units. A conventional boiler burns fuel in a combustion chamber surrounded by a water jacket. This heats the water, which is then circulated around the heating system. Unfortunately, much of the heat produced by the burning of the fuel is either lost to the surrounding air or disappears up the flue. Condensing boilers basically scavenge the heat not recovered by the main heat exchanger and make effective use of it by reducing the temperature of the flue gases to a point where water vapour produced during combustion is "condensed out", releasing latent heat that would otherwise escape up the flue.

Combination Boilers (Combi Boilers)

Combination boilers do the work of both a central heating boiler and a hot water cylinder and they are compact (usually wall hung in the kitchen) which means you either have more space in your airing cupboard, or you don뭪 need one at all. Installation costs may be lower and fitting is often less disruptive than with a conventional boiler. However, because the hot water heats on demand it runs more slowly which means it takes longer to run your bath. Combi boilers are popular in properties where space is limited because they negate the need for hot and cold water tanks.

Condensing Combination Boiler (Condensing Combi)

This is a condensing version of the standard combination boiler, which gives you the extra efficiency of a condensing boiler as well as the advantages of a combination boiler. It can easily be installed as a direct replacement for an existing combination model.

Noises in the Plumbing System

In designing the plumbing system  the plumber will try to make it as noiseless as possible.

Because so much of the noise is due to water traveling at a high velocity, it follows that whatever can be done to reduce the velocity of the water will correspondingly reduce the noise in the system. It is for this reason that it is so important not to skimp on the size of the water supply piping. Larger pipe will not only provide a more adequate supply of water but will reduce noise.
There are three general types of noises found in some of the older plumbing systems. These are water hammer, whistling and chattering.

Water hammer is the thump in the piping heard when faucets or valves are turned off abruptly.  It can usually be eliminated by the installation of an air chamber or short length of pipe in the wall where each supply pipe enters a plumbing fixture.

In some cases, however, the ordinary type of air chamber will not prevent water hammer. In such cases, special devices known as shock arrestors should be installed on the main line near the meter or as close as possible to the cause of the noise.

Sometimes water hammer is due not to the plumbing in the house in which it is heard but to a condition outside of the house, either along the water main or in a neighboring house.

The noise is only an audible symptom of what is going on in the piping. The piping is being subjected to the wear and tear of a multitude of shock waves. The result will be leaks in piping, tanks or fixtures unless the condition is corrected. 
Chattering in the piping may be caused by loose pipes, by pipes rubbing against a metal projection, by worn faucet washers or looseness of other inside parts.
Whistling is caused by the speed of water flowing through piping which is usually too small. A pressure reducing valve will help as will a general straightening out of the plumbing system. Whistling is most common at bends and tees in the pipe.

Sweating Pipes

"Sweating" pipes and plumbing fixtures in summer-time or during seasonal changes are not a sign of faulty plumbing. Due to condensation of water vapor in the air, beads of moisture will form in warm weather on any pipes and fixtures containing cold water.

Normally, when not in use, the water and fixtures will worm rapidly to room temperature and the condensation will stop. When a closet tank or other fixture continues to sweat for hours after it has been used, it is a sign that cold water is continuing to flow through it, possibly due to an improper adjustment of the tank valve or a leak.
Sweating pipes can be wrapped with an insulation material which prevents the condensation and formation of moisture. IE
