London Boiler Installation – Replacement
These boilers come in various outputs,London Boiler Installation meaning they can suit many sized homes, providing there is only one bathroom or shower room. If there is more than one bath or shower to be used at any one time, then a regular or system boiler would be required with stored hot water.
REGULAR BOILERS
Unless the heating system is really old, this would be the most cost effective way of installing energy efficient A rated boiler in your home.
Central Heating Installation Types
Sealed Systems with a pressurised unvented water cylinder
COMBINATION BOILERS
Combi boilers London Boiler Installation are a common way of providing hot water and heating as the boiler houses the components to heat both the hot water and central heating. No water is stored as the boiler fires and heats the water on the turn of a hot tap….
This usually includes a boiler, Boiler Replacement London hot water cylinder in an airing cupboard, big and small water tanks in the loft or top floor and the radiators. Water is heated by the boiler, sent through the cylinder where the heat is given off to the tap water that you draw off in the kitchen or bathroom……
They are especially good in houses where there are a large number of radiators or showers/bathrooms. If your boiler isn’t working then you may have an immersion heater on your hot water cylinder that will provide you with hot water until you get it fixed.
These types of boilers are for larger houses where more than one bath or shower is to be used at any one time and where stored hot water is required.
These are usually installed in flats and houses with no more than 2 showers/bathrooms. They rely on water pressure from the mains to drive hot water through the taps.
A system boiler is a pressurised central heating boiler that incorporates parts of a conventional heating system actually inside the boiler, making installations neater and easier.
These boilers give you instant hot water at mains pressure meaning you get better hot water pressure to your taps and shower at the same time saving you money with only heating the water that you use and not a stored cylinder.
Sealed Systems with a Combi Boiler
Sealed systems are very similar to open vented systems but instead of having a small feed and expansion tank in the loft you should have an expansion vessel somewhere on the pipe work or built into the boiler. These are usually red and resemble a large watermelon in size….
Central heating water is heated by the boiler and diverted to the radiators. This system is open vented as expanding water due to temperature can rise and fall through the open vent in the loft. This is a very common way central heating is installed and works very well if installed correctly.
SYSTEM BOILERS
These systems must be pressurised using cold water from the mains and usually require a minimum of 1 bar of pressure. They work well as they reduce the chance of air being pulled into the system and reduce the chances of an airlock. Not all boilers can be installed on a sealed system and should be checked with the manufacturer.
Open Vented systems with a Conventional Boiler/Back Boiler
The advantage of these systems is that, with good water pressure coming into the property, one can store a large volume of hot water, serve multiple draw offs under mains pressure where a combi boiler might struggle. These must be installed and notified by a qualified engineer to ensure that the safety features are set up correctly.
Although these boilers are still used in conjunction with a hot water cylinder they are pressurised which reduce the risk of air locks, making the system more better balanced and more efficient.
All boilers today, whether it be a combi or any other have to be condensing boilers.
All boilers today, whether it be a regular boiler or any other have to be condensing boilers.
These are becoming ever more popular. Basically this is a sealed system but with a pressurised water cylinder (common makes include Megaflow, Glow-worm). Mains pressure water is stored in the cylinder and is driven to the taps….
A regular/conventional central heating boiler is a boiler that works in conjunction with tanks and cylinder.
Sealed Systems with a conventional boiler
A combi/combination boiler is the most common boiler in and around the UK today. These boilers are great for creating space in your home by removing the need for any tanks or cylinder.
