The heated water ( sometimes referred to as hydronic systems or wet systems) is then circulated from the through pipes to heat emitters ( radiators, convectors and coils), through which the water loses its heat to the room. The cooler water then returns to the boiler for reheating. Central heating generally means that there is commonly only one heat source ( the boiler) that provides both space heating and domestic hot water for the entire house. You can system-link a number of boilers together in a hydronic central heating system depending on the systems required output for both space heating and hot water provision but most family sized homes only require one. What is A Fully Pumped Central Heating System? A fully pumped hydronic central heating system is one in which water from the boiler is circulated ( not pumped as commonly referred) by a circulator to both the and through the heat exchanger ( the coil) inside indirect hot water storage cylinders ( hot water storage optional).

This system incorporates a full range of control options. Generally a fully pumped hydronic central heating system will have a circulator, a room thermostat, cylinder thermostat, a programmer for heating and hot water, a 3 port motorized valve, ( or two 2 port motorized valves), and an automatic by-pass valve. Note: Central heating can also be provided by ducted 'forced air' systems and multi-split air heat pumps systems. For example, a multi-split system has multiple indoor units (a unit in each room) connected to a single outdoor unit - this system can have 2 to 8 indoor units connected to a single outdoor unit. Many of today's brands of heat pumps have 'inverters'.

This technology allows the system to match the compressor's speed output to your indoor heating or cooling load conditions. Basically this means that a heat pump with inverter is a system that can slow down the speed of the fan and the compressor to maintain your ideal environment and in so doing offer greater energy savings over the fixed speed heat pumps that run at full speed then switch off when the thermostat is satisfied and then repeat the process when the temperature has fallen. Most domestic air-conditioners and heat pumps are the same thing as they generally have a reverse cycle, summer cooling and winter heating.

The picture above shows a typical schematic for a hydronic central heating system using a conventional boiler that provides heat for underfloor heating pipes ( coils), radiators, and stored domestic hot water. You can also use a system boiler to provide heat and hot water.

A system boiler is basically a mains fed appliance, a high pressure system that now houses internally some of the components that were previously installed elsewhere in hydronic central heating systems but not inside the boiler itself. For example the ciculator pump, diverter valve, by-pass valve, expansion vessel and filling loop are all now housed inside the boiler, hence the name 'system boiler'. A conventional boiler or a system boiler can be used to provide just heat or just hot water or both.

Must I Store Hot Water? You don't have to have store hot water if you don't want to. If your home is small, or you don't have the space for storage, ( for example a small flat or apartment), then you could use a ' combination boiler' which provides both hot water on demand and heating. Hot water on demand is simply this - as soon as you turn on a hot tap/faucet the burner inside the boiler fires up and heats the water instantly. If you are a single person, or one that is hardly at home, then a combination ( Combi) boiler would be for you as there is no wasting of money and energy heating and storing water that you may not use.

What Benefits Do I Get With A Combination Boiler? What Else Should I Know? You should know that gas combination ( Combi) boilers and system boilers are 'mains fed' operated systems, this means that the water is supplied to both the combi and system boiler at water mains pressure. This is called a 'direct' system. Low pressure boilers used in hydronic central heating systems are 'gravity fed' meaning water is provided from a cold water storage cistern/tank sited at a high level. This is called an 'indirect' system.

Standard conventional gas boilers are being replaced with high efficiency boilers of both condensing and non-condensing types. Condensing combination boilers are now also available. What is A Condensing Boiler? A condensing boiler is a boiler that reuses the heat that would normally escape from the boiler flue to reheat water in a secondary heat exchanger.

When hydrocarbon fuel such as coal, gas and oil are burnt, as part of the combustion process they combine with the oxygen in the air to form water vapour. The latent heat that is used to produce this vapour forms a significant part of the heat given up by the fuel. Because this vapour leaves the boiler, together with the combustion gases through the flue, this heat is lost. If this vapour can be condensed into liquid within the boiler it can then give up this heat which can be transfered to the heating system therefore raising the efficiency of the process. With boilers made from materials such as steel and cast iron it was important not to cool the combustion gases down to the 'dew point' which is about 55°C, the point where gas condenses to liquid.

This liquid ( condensate) is a corrosive acid that can attack boilers and flues. Condensing boilers are made from stainless steel or cast aluminium/aluminum and therefore resistant to the mild corrosive acid of the condensate. The flue gases leave a condensing boiler at about 5 - 10°C above the return water temperature and this is cool enough to allow the use of plastic pipes for the flue construction. Condensing boilers are also less harmful to the environment than conventional boilers because their high efficiency enables them to produce more heat from a given amount of fuel and because less harmful elements in the combustion gases are released into the atmosphere ( even in non-condensing mode condensing boilers are still markedly more efficient than conventional boilers). Types of Domestic Hydronic Central Heating Systems There are a number hydronic central heating system choices at your disposal.

When the heat loss calculation have been made and the boiler sized the choices are as follows: • Hydronic central heating boilers can be either conventional non-condensing, combination non-condensing, or both boilers types ( conventional and combination) can be of the condensing type which is recommended because its more efficient and is environmentally cleaner than non-condensing boiler types. • Fuel can be natural gas, liquefied petroleum gas ( LPG) and oil.

Carbon dioxide ( CO2) levels are much higher for oil than natural gas and LPG. Solid fuel ( wood, coal, wood pellets) boilers can also be used for hydronic central heating and domestic hot water (floor standing only). • System-Link Hydronic Central Heating- automatic boiler ( eg. Conventional boiler) and solid fuel boiler linked both providing domestic hot water and space heating Renewable energy systems: • ground source heat pumps• • water source heat pumps and• ( solar panels) Heat pumps can take low temperature from the soil, rock, water and air, and increase it to higher more useful temperatures suitable for and/or. Solar panels can provide the energy required to run the heat pump, making it a totally clean system.
