Boiler Installation

 

Plumbing & Heating understand that some engineers like to blind their customers with science and inside jargon. We like to keep our clients well informed enabling them to make appropriate decisions. Here's our guide to jargon busting, which we will add to on a regular basis.

Combi Boiler

A combination boiler has all requirements and control systems for the household heating systems incorporated into a single unit. Hot water is provided instantaneously on demand at mains pressure. It's advantages: no hot water cylinder required therefore reducing running costs. No tanks are required in the loft removing potential flood damage and providing more space. There is mains pressure at all outlets thus removing the need for pumps. It's a pressurised heating system and therefore increases heating efficiency and because its pressurised we can locate the boiler almost anywhere.

It requires a healthy volume and pressure of mains water and we recommend good quality makes which offer greater reliability and spare parts are easily available and installed i.e. Worcester Bosch, Potterton, Baxi, Vailiant

System Boilers (Unvented)

A halfway house between a combi boiler and a traditional boiler. The system is pressurised there is no need for a small heating tank in the loft but the large tank and a hot water cylinder remains.

Because its pressurised the boiler can be situated in a wider variety of locations, and the pressurised water transfers heat better. The boiler installations will be slightly more expensive.

Traditional Vented Heating Systems

Most commonly found, it consists of a boiler, hot water cylinder and two tanks in the loft. It comes in two varieties; gravity, which no longer complies with regulations and fully pumped which allows full control o the heating of the hot water and/or heating.

It delivers a healthy volume of hot water on demand, however this means that the running costs are high in order to keep water hot.

Direct Hot Water

Electrically heated water, mainly where the supply of gas/oil is not available. The heating is provided by economy 7 storage radiators. It is a simple system with no complex parts, however it is expensive to heat water. Makes include Ariston, Santon, Megaflow.

TRV

Radiator valve fitted to one end of the radiator. Turns the radiator off when required temperature is reached in the room it is fitted in. I use Honeywell trv's.

Lockshield

A fixed valve on a radiator that controls the maximum water flow through the radiator. This usually has the plastic cap on that cannot be turned.

Power Flushing

Over a period of time the efficiency of your central heating deteriorates as sediment and rust accumulates in the system. Power flushing is a process where the radiators and the connecting pipes are cleared in situ - being flushed! On completion your central heating will be repaired to optimum efficiency.

Inhibitor

Chemicals introduced into your central heating system that will slow down the rusting process of your radiators. We recommend that good quality brands (Kamco, Fernox, Sentinal), are used and handled by a professional, and introduced following a power flush and topped up every three years.

Magnetic System Cleaner

This tool is introduced as part of the heating matrix after power flushing or installation of a new boiler. It attracts rust and magnetic particles returning to the boiler thus reducing the build up of sludge. Must be cleaned out once a year, can carried out by you or part of the annual boiler service. I recommend fitting these to you heating system. A good make to choose is Magnaclean.

Single Pipe Systems

Introduced in the 50s this consists of a single pipe from the boiler servicing all the radiators, there is poor heat distribution with limited control. Some houses still have this system, now not installed and we recommend that if your house has this system we upgrade and introduce extra control to increase efficiency. However upgrading is a big job and connecting a boiler to this system is possible.

Two Pipe System

Has a flow of hot water from the boiler and a return of water for reheating. Ensuring heat is evenly distributed and allows greater control. More water content than the single pipe system but better for altering and adding radiators.

Microbore

Introduced in the 80s as a system of small pipes 8mm or 10mm in diameter. It was a quick and easy system to install however is has limitations with regards to additions, alterations and maintenance. It is unsuitable to power flush but efficiency can be improved through introduction of a magnetic filter. Pipe work can block if not maintained ( flushed out every five years and treatment added). If taken care can be a good system with low water content and quick warm up times.

Programmable Room Stat

A combination of room stat and timer allows greater control and efficiency of the system and we recommend this on most heating systems. Please note: the timer in the stat controls when the stat changes temperature.

Frost Stat

Its primary job is to protect the boiler when located in an exposed location e.g. garages and lofts. Please note: some boilers have frost stat's built in.
